I had Windowtec service & repair the windows in my flat 2 years ago & they did a great job for a fair price. When we bought a new house with some blown glass and unsafe windows I contacted them immediately. They quickly arranged to come and look at the job and provided me with a great quote. Only a week after accepting the quote, the guys showed up and quickly got to work. In just an hour they’d replaced the glass on the conservatory doors and added safety latches to all of the upstairs windows. The conservatory doors were tough to open but as part of their service they fixed that too!Verified reviewerJob location: G6610 Fitting a cat flap in uPVC door

Our utility room window wouldn't close after we had opened it. Called Windowtech and they came out the next day on time as agreed. The window had dropped so they repaired it really quickly and efficiently. Would definitely use them again if we have any further problems.Verified reviewerJob location: G7610 UPVC Repair - Bearsden
