Double Glazing Repairs & Window Replacement

While modern double glazing has evolved to be immensely durable and to require little maintenance outside of an occasional wipe down, sometimes accidents happen and you might find yourself in need of a repair or replacement.

The companies we work with offer double glazing repair and replacement services to have your home looking and performing perfectly once more.

Sometimes a repair job is not appropriate and you will need to get the item replaced. We work with honest and reputable companies, which means they will never suggest that you get a window or door replaced if they think they can fix it.

What is The Average Price For New Windows?

The average price for new windows is between £350 and £400 per window. This means that double glazing a 3 bedroom semi-detached house in Northampton will likely cost between £3500 and £5000.

The price of your double glazing will depend on a number of factors. These are: your preferred style, the size of the window, any optional decorative features you have requested and whether you have opted for a woodgrain finish.

How Much Does it Cost to Install Double Pane Windows?

When you use our online quoting system, our pricing guide tables or our costing calculator, the prices you receive will include the price of installation as well as surveying, a warranty, VAT and a certificate of compliance. This ensures that you are not surprised with unexpected additional costs later on in your installation.

However, for those who would prefer to simply receive the windows and install them themselves, we do work with a number of supply-only double glazing companies.

Installing your own windows is often a lengthy, difficult and time consuming process however, even for an experienced DIY enthusiast. You will also have to deal with administrational things such as building regulations which your installer would otherwise take care of for you.

What Is The Cost of uPVC Windows Fitted?

All of our double glazing prices include the cost of fitting. For example a 500mm x 500mm uPVC casement window in white will cost between £150 and £175. This price includes the price of fitting, surveying, VAT, a warranty and a certificate of compliance.

What is The Cost of New Double Glazing?

The cost of new double glazing will depend on the size, style, decorative accents and finishes that you choose. A simple uPVC casement window for example can cost as little as £150. However, for more complicated designs such as bay windows or bi-folding doors prices will run significantly higher.

I would like to thank the guys for installing my new front door and new back door. Very friendly very professional very clean working very obliging. Would definitely recommend with great confidence. No redecorating or patching required just amazing workmanship..thanks

We hired WFS to build our conservatory after getting a quotatis quote. They were punctual with their appointment and helpful thought my indecisive decision making process! The builders of the base were fast working and efficient, tidy too. A few weeks later the frame went up followed by plasterer and electrician. Our conservatory is beautiful and despite a challenge with the roof of the kitchen looks great! We are happy we chose WFS and looking forward to decorating our new room.

Great company to deal with, professional and friendly all round. Would definitely recommend!

Every one I have dealt with at WFS were very friendly; very professional and hard working. There was no mess to clear up after them. They did it all. I would highly recommend this company.

How much does triple glazing cost?

Triple glazing can be used instead of double glazing and boasts superior thermal efficiency, soundproofing and security. Triple glazing will always cost more than double glazing with a single triple glazed casement window typically costing £110 more than its double glazed counterpart. Triple glazing can be used as a replacement for single glazed windows or old double glazing and will make a dramatic change to the warmth, quietness and security of your home. However, if you are considering using triple glazing as a replacement for modern double glazing, it is important to note that the benefits you see may not be drastic enough to justify the substantially higher price tag.

How much is a conservatory?

A new uPVC conservatory is a great way to enhance both the property value and aesthetics of your home. If you require more space in your home and are considering building an extension, a conservatory might be a great cost effective option that negates the need to apply for planning permission. A simple uPVC lean-to conservatory can be yours for £6000. Check our pricing tables below for guide prices for other styles and sizes of conservatories.

How much does a composite door cost?

Composite front doors are a great way to retain the looks of a timber front door while enhancing your home’s heat retention, weatherproofing and security. Highly durable and available in many different colours and with a variety of glazing and decorative options, composite doors can be customised to look great on any property. As they are a high-end product, prices for composite doors do start high. Prices for composite doors start at £1000 and can increase to £1500 depending on your customisation options.
