Allow us to exceed your expectations

As the pressure increases on house builders to alleviate the UK's housing crisis, new build projects are encouragingly on the rise. As an ethically minded contractor, it is your duty to use only but the best materials for the project. Therefore, we are proud to be involved in this increasingly popular sector; supplying the highest quality uPVC and aluminium products to build the next generation of housing across the South West. This allows new build developers to avoid dreaded new build 'snags', that inevitably come from using lesser quality products.

With a vast knowledge of new build regulations, we can advise you on planning permission guidelines, new build regulation regimes and much more.

"An excellent service all round"

An excellent service all round. Very friendly and took time to ensure the windows were exactly as I wanted. The windows themselves are well made and have completely transformed my house.

"Thoroughly recommend Seal-lite"

We had Seal-lite install full new double glazing including bi-fold doors a little while ago, excellent products and service. Their after sales service by Simon is very, very good indeed. Thoroughly recommend Seal-lite.

"Excellent service from start to finish"

An excellent job done by Paul and his team. Transforming the front of our house with Georgian bar style windows and a fantastic new bay window. Finished off by a new door. Highly recommended excellent service from start to finish.

"Very patient and understanding"

I would absolutely recommend Seal-Lite Ltd. They have been so helpful helping me to match my new aluminium windows to the existing house. They have also been very patient and understanding with me having to delay installation for several months due to problems with my builder. Kevin fitted the windows very carefully and did an excellent job. A couple of minor things were no problem and resolved quickly to my full satisfaction. I would like to thank Paul and Pete and the team for being so so helpful. A pleasure to do business with this company – I wish all companies were like this.
