How Much Does it Cost To Install Double Glazing?

When you use our cost calculators, our pricing tables or receive an online quote, the price given will always include the cost of installation. Also included is the cost of surveying, a warranty, VAT and a certificate of compliance.

For customers who would prefer to have their double glazing delivered and to then install it themselves, we work with supply-only companies as well.

Consider though, installing your own windows and doors can be difficult and time consuming and you will need to sort out your own building regulations information. When you pay for installation, you pay for convenience.

How Much Does It Cost To Replace Windows?

While modern double glazing has adapted to be durable and low-maintenance, sometimes you might find yourself in need of a replacement. Replacements are a last resort, however. Check first to see whether your frames are showing any sign of rotting or warping. If they are fine, consider opting for a glass replacement which will be considerably cheaper.

Our installers offer repair and replacement services and will likely to be able to fix a large number of problems without requiring a replacement.

Repairs can be carried out on broken locks, broken internal beading, misting and window condensation and dents and superficial damage to frames. Sometimes repairs cannot be made and your installer will recommend a replacement. As we work with trustworthy companies, they will never suggest a replacement if they think that a repair job would fix the problem.

Very pleased! Marc in Sales was really lovely and everything went smoothly; professionally organised and the installers were neat and efficient. The window is really nice, my requests were accommodated and it looks so much better than the old window. Thanks T.V.- a big improvement to my bathroom!

We were very pleased with the service we received from Trent Valley for the construction of our new conservatory. Trent Valley were recommended by a neighbour who had a very nice conservatory installed and after doing some research we decided to go ahead with them. It was the right decision as we now have a wonderful conservatory which we will enjoy for many years to come! Thanks to Stacey, Carl, Rob and the team for all their support!

Helpful staff and great customer service. Highly recommend.

Excellent service all the way from quotation to installation. Highly recommend this company for UPVC double glazing. Thanks for a good job.

Triple glazed windows are always significantly more expensive than their double glazed counterparts. Triple glazing offers superior soundproofing and thermal efficiency and can be considered as a replacement for single glazing and old double glazing. However, if you are looking to replace modern double glazing, the price of triple glazing might outweigh any perceivable benefits.
