Peter completely transformed my Kitchen windows at a reasonable price. Service was good from start to finish and I would not hesitate to recommend.
Shenfield, 2018
I found the work undertaken by this company to be highly professional in terms of quoting for the work, the commitment to timescales and the quality of the work undertaken. No shortcuts taken, attention to detail excellent and the end price agreed was most competitive. All in all, I am a very satisfied customer who would have no hesitation either in using the company again or recommending it to others.

“I would highly recommend Peter to anyone, I have had replacement windows and doors fitted by him on two occasions in subsequent properties and he has done an excellent job both times. The work is completed to a very high standard. Always punctual, reliable and tidy.”

“I have used Peter Hargreaves for all my window repairs and replacements for 15 years without any problems. Peter has replaced the windows in; my house, my mother in law’s house and two properties I let to tenants. My mother in law said Peter was very tidy and my tenants said he was great company and they were happy to go out and let him get on with it. I have recommended Peter Hargreaves to my friends who were happy to use Peter because they know how particular I am about details and price.”

“The Window Clinic has recently installed sash UPVC windows to our Edwardian House and I can thoroughly recommend their workmanship.

One of the windows was a bay and I was concerned that damage may have been done to the surrounding brickwork and décor when removing the original windows, but I found the team to be extremely careful and the result was impressive. They left everything neat and tidy and I had to move very little furniture for them to complete the work.”
Lynn Regan

“Very happy with Peter’s work, we noticed he’d been doing a lot of work in our area and he gave us a great price for replacing all our windows. Couldn’t be happier, he and his colleagues did a great job. Highly recommended. ”
