All our work is covered by an insurance-backed guarantee giving you complete peace of mind.
The quality of all new double-glazed window installations must now be certified by law - and AM Windows and Doors provide a certass certificate for all installations. You may also be familiar with FENSA certificates, and certass is an identical body.
Without a certass certificate, you will not be able to sell your home, as it is an important part of your Home Information Pack.
With this guarantee you can be sure that in the unlikely event that your windows should become faulty, we will come to resolve the problem and provide replacement units if necessary.

In addition to your guarantee, we register your installation with Quality Assured National Warranties. By making this insurance payment on your behalf you can be sure that under any eventuality such as AM Windows and Doors ceasing to trade, you can be assured that your warranty will still stand.
