Recently purchased a front door from thermaseal and end to end experience has been great! We visited the Wickford showroom to get ideas. Adam was really knowledgable and talked us through the different options. We discussed different styles and Adam gave advice based on the look of our house. He was really patient despite us changing our minds many times. The door has now been fitted and we are really happy with the style and quality.

I had 8 windows replaced by Thermaseal when I bought my house. Adam Jerwood was really helpful with designing the windows and told us about all the options available without being pushy. Sam and Connor also did a good job of fitting the windows.

After hearing Thermaseal advertise on local radio it promoted me to write this. I'm a retired self employed carpenter and joiner. I used to fit their windows over many years for my customers as part of what I did. I sort out Thermaseal because I wanted a company I could trust and with a good product. Here I found a family run business that always strove to improve the product and design as the industry developed. I got to know a lot about windows and also how some companies we're cheeper because they used cheeper and inferior materials. Once a neighbour asked me to quote him for windows but declined saying he had found a well-known company that was cheaper. Some time after they were fitted I saw him and asked him how it went. "Don't ask" he said. I went and found a catalogue of problems. Apart from damage and ill fitting they had fitted the cheapest cockspur locking system. After months he was still waiting for a scratched window to be replaced. I told him that none of this would have happened if I had fitted them using Thermaseal Windows. I can highly recommend them.

Just bought a house which included a 10 year guarantee on windows installed by Thermaseal. Which turns out to be worthless as I am now told the guarantee is not transferable on sale of the property. Be warned!!

Had new door fitted at the cost of several thousands of pounds as bespoke model door warped within a month or so had second refitted some months later, that warped had to go back to manufacturing process for third attempt as admitted inherent design fault finally fitted a year after original...after much chasing new door is fine as reinforced with steel but only given £100 compensation which is less than 3% of the purchase price not good enough as felt misled on quality of product in first place if not fit for purpose...lets hope this one holds out otherwise i will be wanting a full refund!
