Double Glazing Frequently Asked Questions

Double glazing means that a window has two panes of glass instead of just one. These panes are separated by a small gap, which is usually filled with air or gas. This extra layer helps to create insulation, which makes your home warmer and quieter.

The gap between the two pieces of glass acts like a barrier. It slows down heat leaving your home in cold weather and stops too much heat getting in during the summer. It also helps to reduce noise from the outside. Double glazing is much more effective than single glazing and is now used in most modern homes. It also adds value to your property and makes it more energy efficient.

Double glazing helps by trapping a layer of air or special gas between two panes of glass. This layer is not good at carrying heat or sound, which means it slows both of them down. In winter, this keeps the warm air inside your home for longer, so your rooms stay comfortable without needing the heating on all the time. This can help lower your energy bills too.

When it comes to sound, the extra layer of glass and the gap between them help to block noise from the outside. Whether it’s traffic, people, or other outdoor sounds, double glazing makes your home quieter. This is especially useful if you live on a busy road or near a school or pub. It gives you a more peaceful space to relax and sleep.

Yes, double glazing can be installed in older homes, and it’s a great way to improve comfort and save energy. Many people worry that modern windows won’t suit the look of a period property, but there are now lots of styles that match older designs. For example, you can choose sash windows, wood-effect frames, or designs that follow the shape of your existing windows.

In most cases, the old windows are carefully removed, and the new double-glazed units are fitted in their place. If your home is listed or in a conservation area, you may need special permission before making changes. In these cases, secondary glazing may be an option instead, where a second pane of glass is added behind your existing window. A professional installer will be able to guide you on what’s best for your home.

The time it takes to fit double glazed windows depends on how many windows you have and the size of your property. On average, a single window can be fitted in a few hours. For a whole house, it may take between two and five days. The work is usually done room by room, so your home won’t be left open to the weather.

Before fitting starts, the installer will measure each window to make sure the new ones are a perfect fit. On the fitting day, they’ll take out your old windows and put the new ones in their place. They’ll also seal around the edges to keep your home warm and secure. Most companies will tidy up afterwards and take away your old windows. A good installer will explain the full plan before they begin.

There are a few clear signs that your double glazing may need to be replaced. One of the most common is condensation between the two panes of glass. This happens when the seal has broken, and moisture gets inside. You might notice that your windows look misty and can’t be cleaned on the inside.

Other signs include draughts around the edges of the window, windows that are hard to open or close, or frames that are cracked or damaged. If your home feels colder than usual or your energy bills have gone up, your windows might not be keeping the heat in properly anymore.

Also, if you start to hear more noise from outside or feel that the windows look old or tired, it could be time to replace them. Modern double glazing lasts many years, but like anything else, it can wear out over time. Replacing old windows will make your home warmer, quieter, and more secure.

We install a wide range of double glazed windows to suit different homes and personal preferences. The most common types include casement windows, tilt and turn windows, sash windows, and bay windows. Each style has its own features, so you can pick the one that works best for your home.

Casement windows are hinged at the side and open outwards like a door. Tilt and turn windows can be tilted inwards at the top for airflow or turned open from the side for easy cleaning. Sash windows slide up and down and are ideal for older or traditional-style houses. Bay windows stick out from your wall and make rooms feel more spacious.

All our double glazed windows come with strong frames, energy-efficient glass, and secure locks to help keep your home warm and safe.

The cost of double glazing depends on a few things, like how many windows you need, their size, the frame style, and any special features. Because of this, it’s hard to give one set price without seeing your home first.

As a guide, prices usually start from a few hundred pounds per window and go up depending on the design and materials you choose. Larger windows, bay windows, and shaped frames may cost more. Fitting is included in the overall price, and we’ll always give you a full quote before any work begins.

We offer free quotes with no pressure, so you can see the full cost in advance and decide what’s best for your budget.

Yes, we can fix misted or cloudy double glazed windows. This happens when the seal between the two panes of glass breaks, letting moisture in. The result is condensation or fog inside the window that you can’t wipe away. It can make your windows look unclear and affect how well they keep heat in.

In most cases, we can replace just the glass unit (called a sealed unit) without needing to change the whole window frame. This is a quicker and more affordable solution that brings your window back to how it should be — clear, energy-efficient, and good-looking again.

If your window is misted, it’s best to get it checked as soon as possible before it gets worse.

If your double glazed window doesn’t open or close properly, we can help. Windows can stick or jam for different reasons — like worn-out hinges, damaged seals, or frames that have shifted over time. This can make the window hard to use and may also let in draughts or affect security.

Our repair team will look at the problem and find the best fix. Often, small parts like hinges or stays can be replaced without needing a whole new window. We’ll make sure your window works smoothly and safely again, with no gaps or sticking.

If left too long, the problem can get worse, so it’s a good idea to get it sorted early.

Yes, we repair broken locks, handles, and other parts of double glazed windows. These parts can wear out over time or get damaged through regular use. A broken lock can make your home less secure, and a faulty handle can make the window hard to open or close.

We carry a range of replacement locks, handles, and other fittings to suit different window types. In most cases, the repair is quick and straightforward. We’ll make sure everything is working properly and that your window is safe, easy to use, and secure.

You don’t need to replace the whole window just because one part has stopped working.

Yes, we can replace just the glass in a double glazed window if the frame is still in good condition. This is often the case with misted, cracked, or broken glass. Replacing only the sealed glass unit is usually faster and cheaper than getting a full new window.

We’ll match the size and type of glass to what you already have, or we can upgrade it to something more energy-efficient if you prefer. This way, you keep the same look for your home but improve its performance.

You’ll get clear glass again, better insulation, and a window that works like new — without changing the frame.

Yes, in most cases, repairing double glazing is cheaper than replacing the whole window. If the frames are still strong and in good shape, you can often just fix or change the glass, handles, locks, or hinges.

Repairs are a good option if only one part of the window is damaged or not working well. It saves you money, reduces waste, and can make your window last many more years.

However, if the frames are damaged, very old, or the glass is no longer energy-efficient, a full replacement might be the better long-term option. We’re always happy to check your windows and give honest advice on whether a repair or replacement is best for your home and budget.

You should consider replacing your double glazed windows if they are showing signs of wear or no longer working as they should. Common signs include misted or cloudy glass, draughts, frames that are cracked or warped, and windows that no longer open or close properly.

You might also notice your energy bills going up or your home feeling colder than before. If your windows are over 15 to 20 years old, they may not be as energy efficient as modern units. New windows will help keep your home warmer, reduce noise, and improve security.

Replacing them at the right time can also prevent further damage and save money in the long run.
