Replacement Patio Doors and Frame

“Sliding patio needed replacing. I was surprised by how competitive the Window Ace estimate was after sending an email with a photo and dimensions. I decided to ask Jason to visit and quote as his firm is FENSA and GGFi Registered. There was no hard sell, all questions were answered satisfactorily and the estimate was not increased for the quote. The doors were delivered within nineteen days and fitted on the 20th, well within the six weeks I had specified. Dust sheets were used and all rubbish removed. The work and standard of finish look excellent.”– Customer in Wembley, 19 February 2015

Double-glazing repair (3 windows).

“I had condensation inside the double-glazing window panels (rather unluckily, 3 of them went at the same time...). I rang a few Checkatrade companies, but all were either busy or expensive. Then I rang Jason! I was given a quotation over the phone, and he popped round the same evening to confirm the measurements. The replacement window units arrived exactly when Jason said they would, and everything was installed in under an hour. All in all, 100% excellent experience - friendly and fast, and the new windows are spot on. I would definitely use WindowAce for any future jobs.”– Customer in London, 13 February 2015
