How To Choose Between Patio Doors And Bifold Doors For Your Space

cosyadmin — Wed, 06 May 2026 13:54:22 +0000

Homeowners often find themselves deciding between patio doors vs bifold doors, as both options are designed to bring in natural light, enhance aesthetic appeal, and provide flexible access to outdoor areas.

Understanding the differences between these door styles, from opening mechanisms to frame materials and energy efficiency, will help you select the perfect solution for your home.

Feature	Patio Doors	Bifold Doors
Best for small spaces	✅	❌
Fully open wall	❌	✅
Panoramic views	✅	✅
Space saving	✅	❌
“Wow factor”	Moderate	High

Patio Doors and Bi-Fold Doors

Patio doors, often called sliding doors or sliding patio doors, operate on a smooth track, allowing large glass panels to move effortlessly. They provide sleek sight lines and unobstructed access to outdoor areas, making them ideal for smaller spaces.

Bi-fold doors, sometimes referred to as folding doors, use a concertina-style mechanism, where multiple door panels fold together to one side. This allows the entire wall to open, creating a seamless transition between indoors and outdoors. Aluminium bifold doors are particularly popular due to their slim frames, thermal efficiency, and high-quality construction.

Opening Mechanisms

How bifold doors open

Bi-fold doors operate on a top and bottom track, and the panels fold and stack neatly to the side, allowing the full opening to be unobstructed by fixed panes. Bi-fold doors can completely open up by folding back on themselves, offering greater ease of access between indoors and outdoors. Additionally, bifold doors can open inwards or outwards, which is perfect for homes with limited space.

How patio doors open

Sliding patio doors slide open along one or two tracks, leaving at least one pane covering the opening when partially open. Sliding doors can be opened as far as desired, allowing for flexible ventilation.

Threshold differences

Threshold design also differs: bi-folds can have a flush threshold for a seamless connection, whereas sliding doors need a top and bottom track that may require track maintenance over time.

Views and Natural Light

Both door types bring light into your home, but the way they do it differs:

Sliding doors

Sliding doors tend to provide panoramic views with large glass panes and slim sight lines, ideal for small openings or spaces where less frame is preferred.

Bifold Doors

Bi-fold doors fold away completely, offering unobstructed access and a seamless transition to the garden or patio, perfect for wide openings or entire walls of glass.

The amount of natural light depends on the glazed area, not just the mechanism. Both door options can create bright, open spaces filled with fresh air and natural light.

Space and Layout: Bi-Fold vs Sliding Doors Space Saving

Best for smaller spaces

Sliding doors save floor and lateral space because panels move along a track rather than folding outwards, making them ideal for smaller spaces. Sliding patio doors are better for saving floor space and are excellent for framing wide, uninterrupted views.

Best for large openings

Bi-folds need room for folding stacks either internally or externally, affecting adjacent furniture and circulation, so they are better suited for medium or larger spaces. However, bi-fold doors can provide more space for opening and light by fully folding back, creating a sense of more space and unobstructed access between indoors and outdoors. Their major advantage is the ability to create a seamless transition with no threshold, enhancing both aesthetics and convenience. Bi-fold doors also provide a modern, “wow factor” aesthetic that can replace an entire wall. Bi-folds offer flexible stacking configurations and traffic (lead) doors for everyday access without opening all panels.

Things to consider

For narrow balconies or tight exterior reveals, sliding or lift‑and‑slide variants often prove more practical. Ultimately, the choice between patio doors and bifold doors often comes down to personal preference regarding space, layout, and style.

Thermal Performance and Energy Efficiency

When comparing patio doors and bi-fold doors, thermal efficiency is key. Modern aluminium bifold doors and sliding patio doors use thermal breaks and double or triple glazing to reduce heat loss while maximising natural light.

Slim frames and low threshold designs enhance insulation and provide a seamless connection to your outdoor space, making these doors both energy efficient and accessible. Performance depends on the combination of frame, glazing, and threshold, so choosing high-quality systems ensures your doors stay thermally efficient, durable, and stylish for years to come.

Security and Durability

When comparing door styles, security is a top priority. Modern aluminium bifold doors and sliding patio doors feature multi-point locking systems, anti-lift hardware, and strong aluminium frames to resist tampering and forced entry.

Both door types meet current building regulations, offering homeowners peace of mind alongside a sleek, modern look. With robust construction and advanced security features, these doors provide a safe, stylish, and durable connection between indoor and outdoor spaces.

Cost Comparison

The cost of patio doors and bi-fold doors depends on a number of factors, including materials, glazing, size, and panel configuration. Aluminium bifold doors may have higher initial costs due to multiple panels and complex installation, but they offer wide openings, flexible layouts, and a modern look.

Sliding patio doors are often more space-efficient and can be less expensive to install, especially in smaller openings, while still providing large glass panels, energy efficiency, and durable aluminium frames.

Ultimately, the best choice balances budget, home layout, and desired features, ensuring a stylish, functional, and long-lasting door system.

Installation, Maintenance and Practical Use

Both patio doors and bi-fold doors require thoughtful installation and regular maintenance to ensure long-term performance. Sliding patio doors rely on smooth-running tracks, which should be kept clean and occasionally have their rollers adjusted for seamless operation. Similarly, bifold doors need periodic servicing of hinges and rollers to maintain proper alignment and preserve effective sealing.

With the right installation and ongoing upkeep, both door types remain durable, secure, and easy to use, delivering a seamless connection to your outdoor area.

Final Considerations

In summary, both patio doors and bi-fold doors bring distinct advantages to your home, making them suitable for a variety of architectural styles and personal preferences. Patio doors, with their sliding mechanism and expansive glass panels, offer a sleek, modern look and maximise natural light, making spaces feel brighter and more open. Bifold doors, on the other hand, feature multiple panels that fold away to create a wide, unobstructed opening, perfect for those who want a flexible connection between indoor and outdoor living areas. When deciding between these options, consider factors such as the amount of space available, the level of natural light you desire, thermal efficiency, and your own style preferences. By weighing these elements, you can select the door style that best enhances your home’s comfort, energy performance, and visual appeal.

How To Stop Condensation On Windows And Prevent Mould In Winter

cosyadmin — Wed, 06 May 2026 13:49:06 +0000

If you’ve ever woken up to water droplets running down your window glass, a damp smell in the room, or even the early signs of black mould, you’re not alone.

The good news is that understanding how to stop condensation on windows is relatively straightforward, and in most cases, it doesn’t require drastic changes. With the right balance of ventilation, temperature, and moisture control, you can reduce condensation and prevent long-term damage to your home.

What Causes Condensation On Windows?

Condensation forms when warm air carrying moisture comes into contact with cold surfaces, such as cold glass or a cooler surface like your window pane.

Why condensation forms

When this happens, the air can no longer hold as much moisture, and water droplets begin to form. This point is known as the dew point, and it’s the key reason why condensation forming on windows is more common in cold weather.

Why it’s worse in winter

Indoor humidity levels rise due to heating, cooking, and drying clothes

Outside temperatures drop, creating a greater temperature difference

Homes are more sealed, leading to poor ventilation

Why Condensation Is More Than Just a Nuisance

While a small amount of window condensation might seem harmless, ongoing condensation problems can lead to:

Mould growth and spreading mould spores

Damage to your window frame

Peeling wallpaper and stained exterior walls

Persistent damp smell

Potential health problems, especially for those with respiratory issues

That’s why it’s important not just to wipe it away with a dry cloth, but to properly control condensation at the source.

How To Stop Condensation On Windows

Here are the most effective, practical ways to stop condensation and improve your home environment.

Improve Ventilation Throughout Your Home

The number one cause of condensation issues is poor ventilation.

To prevent condensation, you need consistent air circulation so that humid air doesn’t sit and settle on cold surfaces.

Simple ways to increase ventilation:

Use an extractor fan in kitchens and bathrooms

Open windows regularly, even during winter

Keep an air vent or trickle vents open where possible

Leave a window open slightly overnight if safe to do so

Even opening a window for 10–15 minutes a day can significantly reduce condensation.

Reduce Excess Moisture In The Air

Every day activities create excess moisture inside your home. Cooking, showering, and even breathing all contribute to moisture buildup.

To remove moisture effectively:

Avoid drying clothes indoors where possible

If you must dry clothes inside, use a vented tumble dryer if possible

Keep lids on pans when cooking

Close bathroom doors after showers

The less humid air you create, the less chance you’ll have of condensation on windows.

Use a Dehumidifier

A dehumidifier is one of the fastest ways to lower high humidity levels in your home.

Running a dehumidifier overnight can:

Extract more moisture from the air

Help maintain balanced moisture levels

Reduce the likelihood of condensation forming on your windows overnight

For best results, place it in rooms where condensation is worst.

Maintain Consistent Indoor Temperatures

Big fluctuations in indoor temperatures can make condensation worse.

Try to:

Keep your home at a steady temperature

Avoid letting rooms go completely cold

Heat your whole house evenly, where possible

When warm air suddenly hits a cold surface, it’s more likely to attract condensation – consistency helps prevent this.

Upgrade From Single Glazing

If your home still has single-glazed windows, you’ll almost certainly experience ongoing condensation issues.

Single glazing creates very cold surfaces, making it easy for moisture to settle and turn into water droplets.

Modern double-glazed windows are designed to reduce this problem by:

Creating an air gap between panes

Improving insulation

Keeping the inner glass surface warmer

If your existing units are older or failing, upgrading to a modern sealed unit can dramatically improve your home’s ability to prevent condensation.

You can learn more about Cosyhomes Windows replacement options here.

Check Your Existing Double Glazing

Even if you already have double glazing, condensation can still be an issue if the unit has failed.

Signs of a problem include:

Condensation between the panes

A broken sealed unit

Reduced insulation performance

When the seal fails, the unit can no longer properly trap moisture or insulate against cold air, which leads to increased condensation.

Wipe Away Condensation Daily

While it doesn’t solve the root cause, removing water droplets helps prevent moisture problems from escalating.

Use a dry cloth each morning to:

Stop water from soaking into frames

Reduce the risk of black mould

Prevent long-term damage

Think of this as maintenance, not a full solution.

Improve Ventilation In Problem Rooms

Some areas are more prone to making condensation than others- especially kitchens, bathrooms, and bedrooms.

Focus on:

Installing or upgrading an extractor fan

Keeping doors closed to contain humid air

Increasing airflow in areas with cold walls

Targeting these high-moisture areas will significantly reduce condensation across the rest of your home.

How to Prevent Mould Growth

Condensation and mould go hand in hand. Once mould spores find a damp surface, they can quickly develop into visible black mould.

To prevent moisture from turning into mould:

Act quickly when you notice condensation issues

Keep surfaces dry

Maintain good ventilation

Monitor humidity levels

If left untreated, mould can spread across walls, ceilings, and window areas – and lead to serious health problems.

Learning how to stop condensation on windows isn’t about one quick fix – it’s about managing the balance between heat, air, and moisture in your home.

By improving ventilation, reducing moisture content, and upgrading inefficient windows, you can:

Control condensation

Protect your home from damage

Create a healthier living environment

If condensation issues persist, it may be a sign that your current glazing isn’t performing as it should. In that case, upgrading to modern, energy-efficient units can make a significant long-term difference.

A Guide To Stippolyte Glass

cosyadmin — Wed, 25 Mar 2026 19:56:43 +0000

This privacy glass is called stippolyte glass. In this article, we look at the many benefits of this type of glass, the different styles available, and where you might install this in your home. Read on to learn more.

What is stippolyte glass?

Stippolyte glass is a frosted type of glass that is often used to create high obscuration of the room from the outside looking in. It distorts light as it hits the window and is a particularly good choice for bathrooms.

Another room that you could use this in is a downstairs toilet if you have one. Particularly good if the toilet is street-facing. It’s also often installed in UPVC front doors. The frosted effect will make the interior blurry, soft, and undefined. Privacy guaranteed!

Pros & Cons

If you’re considering stippolyte glass for your home, it’s worth knowing the pros and cons of these types of glass panels.

Pros

Privacy
The most obvious benefit is of course privacy. Stippolyte is an obscure glass and will create privacy in any room that you choose to install it.

Noise reduction
This is an advantage in rooms such as a downstairs toilet as it will reduce the noise of a noisy toilet.

Energy efficient
Double-glazed stippolyte glass creates good insulation, making it energy efficient. They can also reduce condensation which is great in bathrooms where this can be a real problem.

Mould reduction
Mould can cause many health problems and make it harder to keep your windows clean. Installing double glazed stippolyte glass in rooms where there is a lot of moisture, such as your bathroom or shower room, will reduce the possibility of mould occurring.

Styles to suit your preference
Choose from either 4mm or 6mm glass thickness and a pattern to suit your home – from acid-etched glazing to frosted and floral.

Cons

Cost
Stippolyte glass can be expensive.

Too much privacy!
By this, we mean you may actually want to see the other side of the glass. For example, if you have this installed on your front door it makes it harder to know who is there – not so good if you want to avoid cold callers!

How To Fix A Broken Window Lock Easily

cosyadmin — Wed, 25 Mar 2026 19:55:51 +0000

As well as securing your doors, it\’s also essential to secure your windows and fix any broken locking mechanism. A broken window, whether it\’s a lock or window handle, can be a worry. UPVC windows\’ locks have a lifespan of 5-8 years on average however, as they are a moving part they are more prone to wear and tear than a window frame for example.

In this article, we\’re going to look at how to fix window locking mechanism easily and give you peace of mind this holiday season, so you leave no window open but all are locked shut to secure your home.

Identifying the Type of Window Lock

If one of your windows has a broken mechanism, there\’s no need to immediately think that you need to replace the entire window. Firstly, identify what type of window lock your window has. Below are some popular designs:

Sash locks

A sash window lock stops the window from being opened from the outside. Unlike some other windows, a sash lock doesn\’t act as a handle latch and you need to slide the lock up to open the window.

Casement locks

To identify a casement lock on a window, look for a window handle or lever mechanism typically located along the window\’s vertical or horizontal edge, allowing you to open your window and close and lock it securely in a swinging motion.

Sliding window locks

To identify a sliding window lock, check for a latch or lever usually positioned on the horizontal track of the window frame, enabling it to be locked shut by locking the sliding panel.

Gathering Necessary Tools and Materials

Once you have identified your UPVC window lock, you can gather the tools you need to make your repair.

The tools you need include:

Screwdriver – For removing screws from the existing lock.
A replacement window lock – Make sure that you ensure it matches the size and type of your existing one.
Tape measure – To measure dimensions for proper alignment and position.
A pencil or pen – For marking positions and aligning the new lock accurately.

Depending on the specific type of window lock and installation requirements, you might also need:

A drill – If new holes need to be drilled for the installation.
Drill bits – Matching the size required for the screws or bolts.

Step-by-Step Repair Instructions

Start by gathering the tools required, including your screwdriver, tape measure, pencil, and the replacement window lock.
Remove your old lock – Unscrew and remove the existing window lock with the screwdriver.
Measure and align – Use the measuring tape to determine the proper placement for the new lock. Mark the position with a pencil.
Prepare your new lock – Ensure the replacement window lock matches the size and type of the old one.
Drill holes (if needed) – If the new lock requires different screw placements, use a drill and appropriate drill bits to create holes in the marked positions.
Install your new lock – Attach the replacement lock using the provided screws or bolts. Tighten securely with the screwdriver to make sure it is attached.
Test – Test the opening mechanism and confirm that the new window lock functions correctly. A jammed or stuck window is sign that there is a problem with the repair.
Adjust if needed – If the lock feels too tight or loose, make any necessary adjustments according to the lock\’s instructions.

Drafty Windows: Causes and How to Prevent Them

cosyadmin — Wed, 25 Mar 2026 13:21:10 +0000

Drafty windows are a common problem that can significantly affect home comfort and energy efficiency. During the colder months outside temperatures are lower and a drafty window allows cold air in and warm air out, making it harder to maintain a cosy home.

Beyond discomfort, these drafts can lead to a high heating bill as your heating system works overtime to compensate for the temperature loss. Addressing this issue is essential to keeping your home both comfortable and cost-efficient year-round. In this article, we look at common causes of draft windows, how to identify them, and how to fix drafty windows or whether window replacement is a better option.

What Are Drafty Windows and Why Do They Matter?

Drafty windows and doors or leaky windows are caused by gaps or poor seals that let outside air in and warm air out, causing drafts. This increases energy bills as heating or cooling systems work harder and can lead to moisture issues like condensation or mould. Fixing drafty windows to block drafts improves home comfort, increases energy savings, and protects your home from damage.

Common Causes of Drafty Windows

Poor Window Sealing

Deteriorated silicone caulking, or weatherstripping allows air to pass through gaps, leading to drafts. Regularly inspecting and replacing seals with quality materials can reduce energy loss and improve comfort.

Ageing Windows

Old windows often lack modern insulation and develop wear that leads to drafts. Upgrading to new windows that are more energy-efficient, with double glazing or better sealing technology, can drastically stop drafts, enhance insulation and reduce your energy bill.

Damaged or Warped Frames

Window frames can warp, develop small cracks, or rot over time, creating small gaps for drafts. Repairing or replacing damaged frames with durable materials like uPVC to create a tight seal ensures better insulation and longevity, preventing window drafts.

Single-Pane Glass

Single-pane windows lack insulation, making homes more prone to drafts. Replacement windows that are double-glazed prevents heat loss and improves thermal performance.

Gaps or Improper Installation

Poor installation can leave gaps around the window panes and frame, letting air in. Resealing or professionally reinstalling the window ensures a tight, draft-free fit, improving efficiency.

How to Identify Drafty Windows in Your Home

The Candle Test To Check Air Movement

Light a candle and move it around the edges of your window frame. If the flame flickers, it indicates air movement from a draft. This quick test is especially effective on windy days to pinpoint window gaps.

Visual Inspection

Check for cracks, gaps, or deteriorated caulking around the frame. Look for signs like daylight peeking through, which indicate drafts and require attention.

Feel for Air Leaks

Run your hand along the edges of the window to detect cold air or movement. This helps you quickly identify cold air coming in and where to seal windows.

Solutions for Preventing Drafty Windows

Re-Caulk and Replace Weatherstripping

Applying fresh caulk and replacing old weatherstripping can seal gaps and stop drafty windows. These cost-effective and easy fixes are quick and help insulate windows and stop window drafts.

Install Window Insulation Film

Insulating film adds an extra layer to reduce drafts and heat loss. It’s easy to apply and an affordable option to improve window insulation during colder months.

Upgrade to Energy-Efficient Windows

Replacing old windows with double or triple-glazed energy-efficient models significantly improves insulation. This upgrade reduces drafts, lowers energy costs, and enhances overall comfort.

Add Thermal Curtains or Blinds

Insulating curtains or blinds are an extra barrier against drafts, preventing cold air coming in and keeping warm air in. They are a stylish and practical way to improve window insulation.

Use Draft Stoppers or Window Inserts

A draft stopper or inserts block air leaks and are easy to use for a seasonal or temporary solution.

Repair or Replace Damaged Windows

Fixing cracks, warped frames, or broken glass panes helps seal drafty windows. For severe damage, replacing the window improves long-term insulation and performance.

Benefits of Fixing Drafty Windows

Lower Energy Bills

Fixing drafty windows reduces energy waste by preventing heat loss, allowing your heating or cooling system to work more efficiently. This can save money on monthly energy bills.

Enhanced Comfort

Eliminating drafts creates a more consistent indoor temperature, making your home warmer in the winter and cooler in the summer, creating a comfortable living space all year round.

Better Air Quality and Reduced Condensation

Sealing drafts helps prevent outdoor pollutants from entering your home and reduces moisture build-up that can cause condensation. This improves indoor air quality and reduces the risk of mould or mildew.

Increased Home Value

Upgrading or repairing windows enhances the overall appearance and energy efficiency of existing windows in your home. These improvements can increase property value and appeal to potential buyers.

Conclusion

Addressing drafty windows is crucial for creating a comfortable, energy-efficient home. By identifying and sealing gaps, upgrading to energy-efficient windows, or using simple solutions like thermal curtains, you can reduce energy waste, enhance comfort, and protect your home from potential moisture issues. If drafts persist, it might be time to consider a window upgrade for long-term benefits.

How To Fill Cracks Around Window Frames

cosyadmin — Tue, 17 Mar 2026 19:07:33 +0000

Sealing window frame cracks is crucial for energy efficiency and comfort and should not be left unaddressed. It prevents drafts, can reduce energy bills, and excess moisture, which can cause mold and water damage elsewhere. Properly sealing cracks ensures long-lasting results, enhances window performance, and preserves your home\’s value.

In this article, we\’re going to look at the process of how to fill window frame cracks including the tools and materials you will need, as well as advice on filling the cracks.

Tools and Materials You\’ll Need

Some tools and materials that you\’ll need to repair cracks around the window frame are:

Caulk Gun: This is for applying caulk smoothly and evenly.
Utility Knife: To cut the caulk tube tip and remove old caulk.
Putty Knife: This is for scraping away old caulk and smoothing new caulk.
Cleaning Supplies: Such as cloths and soapy water to clean the area before sealing.
Masking Tape: Mask off areas and ensure clean caulk lines are used.

You may also need a backer rod to fill larger gaps or voids before applying caulk to ensure a more effective seal.

There are different types of caulking that you can use on a window frame when repairing:

Silicone: Best for non-porous surfaces like glass and metal, offering excellent flexibility and water resistance.
Acrylic Latex: Ideal for painted surfaces and easy to clean up with water, though less flexible than silicone.

Backer Rod: Ensure a proper seal is used to fill larger gaps before caulking.
Expanding Foam: Useful for sealing and insulating larger cracks and gaps.

Having these tools and materials on hand will help you seal cracks around your window frames effectively, enhancing your home\’s efficiency and comfort.

Preparing the Work Area

To remove old caulk and debris from the crack:

Use a Utility Knife: Carefully cut along the old caulk to remove it from the crack.
Scrape Debris: Use the utility knife or a putty knife to scrape away any remaining old caulk and debris.
Clean with a Damp Cloth: Wipe the area clean with a damp cloth to remove dust, dirt, and residue. This ensures better adhesion for the new caulk.

Proper preparation is important for a successful repair as it ensures that the new caulk adheres well and forms a tight seal. Removing old caulk and debris allows the new caulk to bond properly with the surface, preventing air and moisture infiltration. A clean surface also results in a neater finish and prolongs the lifespan of the repair, contributing to the overall efficiency and longevity of your windows.

Filling the Cracks

For Small Cracks (using caulk):

To load the caulk gun, insert the tube and push the plunger forward. Cut the nozzle at a 45-degree angle, then squeeze the trigger while moving steadily along the crack. Finally, use a wet finger to smooth the caulk for a professional finish.

For Larger Gaps (using backer rod and caulk):

The backer rod prevents overfilling with caulk by controlling the depth of the sealant. To use it, press it into the gap, ensuring it\’s slightly below the surface. Then, apply caulk on top, following the same method as before, for a smooth seal.

Conclusion

Properly sealing cracks around window frames offers your house numerous benefits, including improved energy efficiency, enhanced comfort, and protection against moisture damage. If you feel that the cracking is a larger problem rather than a cosmetic issue, or there may be structural issues, contact Cosyhomes Windows for expert servicing and repairs. We can ensure your windows are properly sealed for optimal performance and longevity. Contact us here.

How To Adjust UPVC Windows

cosyadmin — Sun, 08 Mar 2026 19:06:18 +0000

UPVC is a material chosen for window frames for its durability. Unlike other materials like wood. It is also water-resistant.

If you live in a modern building, it\’s very likely that your windows will be double glazed and UPVC. However, if your UPVC windows have been installed for some time, you may find that you have trouble opening and closing them. Maybe they have warped slightly and need a bit of adjustment.

Depending on the problem and whether you are confident with DIY, you can probably adjust the windows yourself.

In this article, we look at some common problems with double glazing UPVC windows and how you can fix them. Read on to find out more.

Why Isn\’t My UPVC Window Closing Properly?

If your window isn\’t closing properly – perhaps it is sticking – you will need to adjust the height.

This is fairly easy to do and can be done by loosening the screws at the side of the window. Turn the screws with a screwdriver and then readjust the sashes into the frame. Next, tighten them up again. It might be worth asking someone to help you when doing this.

What If The Problem Is With The Hinges?

If you think that the hinges on your windows may be past their best, rather than refitting the window hinges yourself it\’s worth contacting a double-glazing company who can replace them. We\’re happy to help with this, just request a callback.

Are Top-Hung Windows Harder To Adjust?

If your windows swing open from the top or the bottom, these are called top-hung windows.

These windows need to have enough friction on the hinge so that they will stay open. If you have too much friction though, they can be hard to open.

Top hung windows have hinges with a friction stay. This friction stay can be adjusted on the hinge – either tightened or loosened – to apply or release pressure to hold the window open or loosen the window hinge.

When adjusting you need to locate the friction stay on the hinge and adjust the screws in the right direction.

Will I Damage The Window If I Do A Repair Myself

Depending on the amount of adjustment, there is always a risk that you may damage the window if you do the repair yourself. If you adjusted screws and were unable to put them back, or couldn\’t close the window properly, this would be a home security risk.

If you are not confident or would just like the reassurance of using someone who is a specialist, always err on the side of caution.

At Cosyhomes Windows, we offer a range of window repairs and can advise you on the best course of action; more often than not the answer is simple and quick. We have a wealth of experience and can find the right solution for you.
