Double glazed window prices

We believe that each and every one of our customers is unique, therefore each window quote we carry out is specifically tailored to you, your home and your particular project requirements. Your home matters to us, which is why our window prices aren’t just off the shelf – they’re precisely custom-made, especially for you and your family.

You may be questioning why some window companies show prices on their website. The answer is quite simple; A-rated, made-to-measure windows must be individually priced, whereas standard sized windows with basic accessories tend to have set window prices.

How much do windows cost?

There are many factors to take into consideration when calculating window prices and it’s essential to bear in mind that the more you invest in your home, the more you’ll get out of it.

Fundamental window pricing factors include:

Quality of service

If a home improvement offer seems too good to be true, chances are that it is! It’s much more worthwhile to pay that little bit more for an outstanding window product that will stand the test of time (like ours!), than pay less for substandard workmanship that will cost more to fix further down the line.

Do you trust reviews? We score higher than the larger installers you’ve heard of!

Number of windows

The number of windows your south-east home requires will drastically alter the overall price of new windows; the more you order, the more savings you acquire.
