What our customer say about us

Replacement window following a garage conversion
Verified Review
Great experience from start to finish. From an initial enquiry, a rep came to measure and quote before ordering our window, communication before installation was great and the two guys arrived early to fit it very quickly. Would definitely recommend and use again ourselves

Excellent from start to finish
Verified Review
We were very impressed with APS from start to finish. When Andy came to look at our property he was very friendly and spent a lot of time listening to what we wanted. The office team then gave us various quotes and were always very willing to help with any queries we had. The fitting guys, Martyn and Michael, were excellent - professional, friendly, tidy and the finish was really neat - we were very impressed. We would recommend APS and will use again when we need to replace any more windows or doors.

New windows and doors

I recently had the pleasure of having new windows and French doors installed by APS window company in my home, and I couldn’t be happier with the results. From start to finish, APS provided exceptional service and professionalism. The installers, Harry and Jake, were absolutely amazing. Their attention to detail, skillful craftsmanship, and friendly demeanour made the entire process smooth and enjoyable. They went above and beyond to ensure that the windows and doors were installed flawlessly, taking great care in every step of the process. APS were outstanding. Thank you

Installation of new windows and Doors
Verified Review
We have no hesitation in recommending APS Window Company, to replace your windows and doors. From our initial contact with them, deciding on the products, getting the quote, the surveyor and the girls in the office, the staff dealt with us in a professional and friendly manner. I cannot praise the guy who led the installation enough, he was absolutely fantastic and a pleasure to have in our home. The standard of work was immaculate, one of the tidiest workmen I’ve ever seen, and the quality of the windows and doors are exceptional. We are very happy customers.

To replace all widows and doors on the rear ground floor of our house
Verified Review
It is a privilege to have this company local to us. We went to them on recommendation of a friend and so glad we did. The company does not get involved in any 'hard' sales techniques and simply quotes a very fair price for the required work and also valuable advice is given in order to bring the most satisfactory results. The fitters were courteous and friendly and most skilled at their profession.
