What our clients think

“Our new windows have made a huge difference to the warmth and energy efficiency of the house; and aesthetically, it is exactly what we were looking for. We wanted the windows to look like the originals, and they do. In fact, we’ve had visitors who haven’t even realised we have had them changed – a perfect validation that Met Therm Windows was the right choice.”
Michael and Christine
1920’s home

“They were really quick and there was no disruption at all. The internal door took the longest and they did brilliantly with the windows because the houses around here are so old and the walls aren’t straight. But they made everything fit perfectly and the overall look is brilliant.”
“The quality of their work is amazing. The installers did such a good job, and they were so clean and tidy, nothing was too much trouble.”
Janet
Victorian mid-terrace

“The process of working with Met Therm was brilliant – and easy. They came out equipped with samples, did a site survey and took measurements off plan. They were also really helpful as they gave some great recommendations when it came to deciding how many openings to have.”
“Because we were both replacing windows and installing windows into a new build there were definite deadlines which had to be met, such as getting the property watertight. Met Therm happily liaised with our builder and pulled out all the stops to ensure this happened.”
