Testimonials

"My dad had been trying to get a cracked window on his conservatory roof replaced for years, but every company we spoke to said it was a nightmare job. Then Mark from Change came to take a look, and nothing was a problem for him. Today, Mark and his team came to fit the new glass, and they were like Spidermen up on the roof! They did an amazing job—quick, professional, and totally unfazed by the challenge. Not only that, but they left the house cleaner than when they arrived! Seriously impressive. Highly recommend Change if you want the job done properly, with no fuss and a great finish. Thanks again, Mark and team!"

"Mark James and all the team were polite and friendly and extremely efficient. They mended my broken lock so quickly and tidied up any mess they had made. I will definitely be using them again as they have given me a free no obligation to buy quote for my windows which again is a great price. I'm a very happy customer."

"Absolutely fantastic service from The guys at Change. Very professional from start to finish. We will definitely be using them again and have recommended them to our families. It’s nice to find the type of guys you would be happy to have in your home while you’re out at work. And thank you to Emma for all the emails updating us on our order and answering any questions we had."

"How I wish I could put 10 stars!! Mark and his team have done the most amazing job of replacing all my windows and doors. They worked efficiently, were very pleasant and absolutely nothing was too much trouble for them. Each day everything was left neat and tidy and the finished job is just perfect. I shall certainly make sure I recommend them to anyone considering window replacement. Thank you so much for a brilliant job."

"From start to finish it was a pleasure to deal with james, mark and their team. We asked them to reseal the upstairs windows and replace a sliding patio door at the back of the house with French doors. The quality of the product and the work was excellent. Mark and his colleague went the extra mile to minimise disruption to our day and other work we were having done. Thanks v much."
