From Nailsea East End to Nailsea West End

Known for its coal mining and glass manufacturing history, Nailsea has some superb community buildings such as the medieval Tithe Barn and the National Trust’s Tyntesfield House and Gardens to explore. With quaint weekly markets, the farming industry still has strong roots here. With many delightful countryside walks and special scientific interest sites to discover, why not allow the lovely countryside into your home further with a beautiful bifold or a superb sliding door?

A flourishing North Somerset town

It's widely believed that Nailsea took its name from the Old English for “Naegl's island”. Diversifying its economy to service industries these days, this modest North Somerset town is surrounded by curious biological Sites of Special Interest as well as gentle nature reserves; perfect for outdoor explorers. It's also encouraging to note that Nailsea's Trendlewood Community Park has received Green Flag status (2018), setting the benchmark for Somerset public parks and green spaces.

The most notable resident of Nailsea has to be ‘Adge’ Cutler, aka "The Bard Of Avonmouth,"; frontman of Somerset’s beloved folk singers The Wurzels. With many fine examples of Grade II listed buildings combined with newer property developments, whether your Nailsea home or business is traditional or contemporary we’re positive we have the ideal renovation product to suit your individual requirements.

"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.
