Highlights
"I found it's difficult to open the bottom window, not enough space and left a trace in bottom of window sill. Has called and waiting for him to come and fix it"
"Bob did a great job of replacing the window and door on my garage. A large pane in the window arrived with a blown seal. They fitted it to secure the window, and returned to replace it with zero fuss. There was some miscommunication over a pane in the door. Again, this was changed without fuss. I believe that most people are fine when things are going well, and you only really tell quality, in how people respond to problems. Bob responded with great integrity. I would be happy to use again."
"Bob from Warmseal was fantastic from start to finish and I would certianly use them again and recommend. Warmseal fitted a new porch door, the quote was miles better than any of the national companies we looked at. Bob was honest and up front about cost which included fitting and VAT what was even better was that it was ordered, made and fitted within 3 weeks no messing no fuss. Bob was also excellent at communicating and kept us updated on any progress and was flexibe to work around our schedule."
