For a protected home

Our varied collection of enduring door styles has strength, stunning aesthetics and energy efficiency at the core of each design. From contemporary to more traditional styles, our double-glazed replacement doors dramatically retain and conserve energy within homes and businesses right across North Somerset and Bristol; so much so, they can considerably reduce heating bills.

With energy efficiency firmly in mind, we only offer ‘A’ and ‘B’ energy rated glazing alongside our first-rate door frames. Combined with some of the lowest U-values possible and able to accommodate both double and triple glazing comfortably, our doors will keep your home draught free, comfortable and secure for many years to come. We also have an extensive range of door Fab ‘n’ Fix hardware to choose from, including letter plates, balmoral handles & knockers to name but a few.

"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.
