Testimonials
Just a brief note to thank you and all the team at Thermaseal for doing such a great job on replacing our patio doors. The quality, attention to detail and customer service have been outstanding. Everything was left clean and tidy and we will be sure to recommend Thermaseal to others in the future. Many thanks.
Mike & Janette Tadman
Whole experience professional and installation carried out without any mess.
Mr. & Mrs. Stark
My wife and I are delighted with the finished product. Whilst your windows are extremely well made and come up to our expectation, it is the way they have been installed with which we are most pleased. Your installers made virtually no mess and have finished the inside to such a high standard that it is almost impossible to tell that major work has been carried out.

The external finish is good as well and the new windows have transformed the look of the house.

All in all it has been a pleasure to do business with your company. Please give a "well done" to all involved and please feel free to use me as a reference should future customers wish to talk to a satisfied client.

Mr. Sewell - Wickford
