Installation of a cat flap
Tom and his team installed a cat flap for us and I highly recommend his company. Tom is very professional in his communication, clear pricing and reliable. Excellent service and I will definitely use him again.Verified reviewerJob location: NW9RSylvia B10 Window Fitters

Top quality finish and team!
We had 4 windows and a balcony door replaced - the guys at The Window Group were great. It was quite a quick turn around from ordering to fitting. Tom was great with communication, quotes and answering all our questions. Sebastian and Peter fitted the windows, they protected flooring and furniture, were polite, considerate and did a great job! We are super happy with the finished result and would definetly reccomend.Verified reviewerJob location: KT610 Secondary Glazing
