window buying process
Durable uPVC windows are highly weather resistant
Our uPVC windows come with a 10-year guarantee, however they’re likely to last for at least 35 years. And another benefit of our modern uPVC is that they don’t require any upkeep. We simply suggest wiping the frames down with a damp cloth every so often to remove any debris.
We use a high-quality protective coating on the uPVC frames which eliminates the colour from fading. This also protects the frames from warping, cracking or splitting, ensuring that you’ve made a sound investment which will perform for years to come.

uPVC window FAQs
We know that choosing new windows can take a lot of research so here are some frequently asked questions we get about uPVC windows
What is a uPVC window?
uPVC is made from unplasticized polyvinyl chloride (uPVC), also called vinyl. This material is injected into a mold which makes the frames of the window.
How long will my uPVC windows last?
Our high quality uPVC windows are made to last the lifetime of your home.
How do I know when my uPVC windows need replacing?
uPVC windows built in the 1990's were not made as well as we can make them today so if you have some from that period it may be time to consider replacing them.
Single glazed windows will not be as energy efficient as modern double or triple glazed windows so replacing them as soon as possible can reduce your energy costs now and in the future
