"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.
