Thermaseal Window Systems LTD
We are a successful and growing manufacturer and installer of PVC-u double glazing, patio doors and conservatories including conservatory roofs. We also manufacture a range of composite doors incorporating a selection of stain glass designs.
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.
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.
May I take this opportunity to thank everyone involved in tis project for their hard work in bringing the conservatory to completion. The builders and fitters are a credit to your company and my wife and I were very impressed by their professionalism.
It is a pleasant change to have workman arrive when they say they will and to be polite and courteous and to show respect for our home whilst working in it. Nothing was too much trouble for them. We would have no hesitation in recommending your firms to others.
I'm writing to convey how pleased we are with the outcome of the work Thermaseal carried out renewing our double glazing. Not only was the work carried out expertly in clean and tidy conditions but with good humor and pleasantness.
We were consulted when decisions had to be made and given good guidance on the more technical reasons for making those decisions. Please convey our thanks to your technicians Dave and Ben Subsequently when a problem arose on the porch door (nothing to do with the work) we were given help very quickly and subsequent to that when a problem arose from a building aspect (covering angle iron support beam), Dave at Wickford, although very busy, afforded us his valuable time to advise us and help us out.
We at Thermaseal Windows Systems provide our services mainly in Essex, however we do have projects covered in London and in other areas, if your area is not specified in the following list, please call us 01268 561717 and we would be happy to help.

We are thrilled with the result - so much so that we are thinking of completing the house with Patio / French Doors.
We are writing to thank you for your excellent service. We had a Front door, French doors and a Kitchen window that required some additional brickwork. Our timescale was shorter that normal, but you came through in record time and completed to a very high standard. The brickwork needed 4 different brick types / colours and this is now as good as the original, you can't see the join!!
