Window Installer FAQs

Where can I get one double glazed window?

Most window installers will be able to provide you with one double glazed window and fit it for you. If you’re replacing one double glazed window in your home, ask them to try and source the same windows that you already have or find one that’s very similar. Externally, you probably won’t be able to notice the difference, but if your existing windows are very old there may be some exterior discolouration and the locks and handles might look slightly different.

If you want one double glazed window so you can fit it yourself, there are lots of online companies that can supply you with one window. However, window fitting is a skilled trade and you might want to consider whether you have the right tools and experience to fit it yourself. Of course, you’ll save money on installation costs, but if something goes wrong, you might end up shelling out to get it fixed anyway.

The other thing to consider is that any replacement windows need to be certified that they meet Building Regulations. If you fit the double glazed window yourself, you’ll need to apply to your local council building control officer to get a certificate that confirms that you fitted the window within the regulations. You’ll have to pay a fee for this, and it will be even more expensive if Building Control say that the window hasn’t been fitted within the regulations and you have to start again.

The alternative is to ask a reputable window installer that is registered with a self-certification scheme, like FENSA, to install the window. That means that they can self-certify that the window meets building regulations once they’ve finished the installation.

What is double glazing?

If a window is double glazed, it has two panes of glass that have a space between them containing argon gas. The gas works as an insulator, keeping heat inside the house as well as reducing noise. It also strengthens the window.

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

how deep do footings need to be for a porch?

No matter how big or small a building is, it can only be as good as it’s foundation - and that’s a fact! It all starts from the footing and when it isn’t deep enough, unlike badly installed gutters or gapped hardwood flooring, can make the whole building collapse to the ground. Just like any code recommendations, the depth of the footings of your porch is a parameter that must be complied with and adjusted to suit your local code requirements.

As a rule of thumb, you should always dig below the frost line when excavating your footings. At this depth level, the moisture present in the soil will be frozen. Ultimately, this will help the ground to act as a barrier to insulate the soil below the footing from freezing during the cold months. As a result, in regions where the weather is almost always very cold the depth of your footings is expected to be at least 48 inches. But in areas featuring a warm climate, you may be allowed to install your footings on grade.

In addition, it’s compulsory that your footings must be installed at a minimum depth of 12 inches below unsettled soil. However, if you’re constructing the structure into a steep hill’s side or by the side of a retaining wall, it’s required that you maintain the least distance to grade both vertically and laterally. In the event whereby you need to achieve a good lateral barrier, you’ll need to have your foundation dug a lot deeper compared to if it’s on a flat surface. For a more accurate and updated information, you can consult your local building inspection department to get familiar with the requirements in your area.

How much does one double glazed window cost?
How much one double glazed window costs is based on a few factors. If you just want to buy the window to install yourself, it will cost less than if you want an installer to fit it for you. If you want to simply buy one double glazed window without installation it could cost anywhere between £100-£300. That’s for a simple casement window, but other types like sash or tilt and turn windows could cost more. It’s recommended that you get a reputable installer to fit your double glazed windows because they’ve had the relevant training and will be able to install it much more quickly. How much it will cost for them to install one double glazed window will very based on your location, the type of window, how difficult the window is to access and whether you choose standard white uPVC or a coloured or woodgrain effect. An average uPVC casement window might cost somewhere between £300-£400, while a dual turn window might cost between £550-£660 to install. Do you really need to replace the entire window? If it’s just the double glazing that needs replacing, for example if it’s misted up inside, this will cost much less. Most window installers or a glazier will be able to just replace the sealed unit inside, and that may cost as little as £250. It’s always best to get a range of quotes from reputable companies so you know you’ve got a great price and you’re sure you’ll get excellent service.

how long does double glazing last?

Just like every other thing in your house, your double glazed windows have an expected lifespan attached to it as it gradually becomes less functional and less efficient over time. Although there are actually top quality windows which are able to last a very long time, but the fact still remains that nothing can stand the test of time or last forever. Even the best quality double glazed windows will eventually need to be replaced at some point. So exactly how long do double glazing windows last before need a replacement?

To make it brief, most double glazing window units are typically expected to last an average of 20 years. This number of years can, however, vary within the range of 10 to 35 years based on the several factors such as the type, quality of materials as well as installation and where the windows are located.

The reason for the depreciation in double glazing windows is, over time, the windows may be subjected to some wear, tear as well as all kinds of minor damages which includes gas filled insulated glazing unit slowly and gradually leaking. According to the Centre for Sustainable Energy, the evaporation of 25 percent of gas will ultimately minimize the windows’ thermal performance. And when this occurs, fitting a secondary glazing measure or replacing the windows should be put into consideration.

Another factor leading to the gradual depreciation in double glazing windows over time has to do with condensation. When the window collects between the layers of glass due to the failure of the seal of the perimeter and the saturation of the desiccant, can only be solved by IGU replacement.

And finally, the ravages of time also has a way of taking its toll on double glazing windows. This can happen in so many ways such that the window becomes a lot less efficient and later needing to be replaced.

What are the other double glazing options?

Double glazing frames don’t just have to come in uPVC and are available in other materials including aluminium and wood too. Wooden or timber windows are more suited to properties with a traditional look and are often the frame of choice for listed buildings and homes in conservation areas. When properly maintained wooden windows can last well for years but can be up to three times more expensive than uPVC.Aluminium is the strongest and most durable option. As a metal it is highly resistant to the UK’s changing weather conditions and won’t rust, warp, crack or peel. Aluminium offers a modern appeal and is available in a range of colours.

Will double glazing increase my property’s value?

These days, buyers expect homes to have double glazing. People recognise the benefits of installing double glazing, so if you don’t have it installed you should consider it. You’ll increase your property’s value and give it a better chance of selling faster, since single glazed properties are also more likely to have problems with damp and mould which could put buyers off.
