Just wanted to say thank you to you all. Service was excellent from initial enquiries to home visit survey and instalment. We are very happy with our windows and will definitely use them for future projects 😄

We had Windows Plus replace our external doors, we are very pleased which was undertaken by one of their fitters. We are really pleased with all the work and the help they gave us, they are very polite and we would highly recommend Windows Plus to anybody. Many thanks.

Brilliant service. We are very pleased with our new windows and doors. Exceptional service all round. We will definitely be using them again when we get round to replace our remaining windows. Thank you to all of you.

We spent months shopping around for quotes, finding some that were extremely expensive and others that seemed suspiciously cheap. In the end, we chose Windows Plus thanks to their no-pressure sales approach. Visiting their branch in person also helped reassure us that we were making the right choice. The installation was excellent, taking just a couple of days, and the fitters were professional, courteous and clearly took pride in their work. There were a couple of minor adjustments needed after installation, along with an issue involving some damaged glass, but every problem was dealt with promptly and without any fuss. Replacing all your windows and doors is a significant investment, so finding a company that makes the entire process straightforward and stress-free is invaluable. Everyone at this branch made the whole experience an absolute pleasure, from start to finish. A huge thank you to everyone involved for all your hard work and excellent service. We couldn’t be happier with the experience and would wholeheartedly recommend Windows Plus!

Had our windows and doors replaced 4 years ago and was really pleased with the service and quality of product throughout our experience. We recently had to call on the guarantee for a window that had blown, a couple of emails later and had the window ordered and informed us when the window was available from the manufacturer, they made contact to arrange the replacement, and while here sorted a couple of minor niggles we had. Friendly and efficient service would highly recommend. One of the best calls on guarantee we have had to make.

Absolutely fantastic service from start to finish. The team was professional, friendly, and incredibly knowledgeable throughout the whole process. The windows look amazing and have completely transformed the appearance of our home. Installation was quick, tidy, and completed to a very high standard. Communication was excellent, and everything was finished on time with no hidden costs. You can really tell they take pride in their work. I would highly recommend this company to anyone looking for quality windows and reliable service.
