Testimonials
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.

Mr. J. Walshe - Upminster
The prospect of having work done in one's home is rarely without some concern, especially when using a firm for the first time. I am very pleased to advise that the installation of our replacement bedroom windows and a front and rear door has been very satisfactorily performed.

Your employees, Dan & Dave were just as you advertise "Polite and Professional". They arrived early and got on with the job straight away. Dust sheets were laid everywhere required, there was no music and the job was left very neat and tidy, hovering as each part was completed. They answered our questions fully and patiently and of importance to us re-affixed the phone point and door bell very neatly and with no fuss or quibble.

To summarise our experience, we are thoroughly satisfied with the product and the installation. We have considered the extra worth paying and have no hesitation in recommending your organization.

Mr. Sellar - Southend - on - Sea
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.
Thanks to yourself, Dave(Wickford), Dave and Ben(technicians) and Steve, technician who was also involved. I would recommend Thermaseal to anyone.
