Angela T

“From start to finish I have been looked after so well by Jason & his team. The whole process was made so easy & nothing was too much trouble. Any home improvements can be stressful, but I can honestly say it was a walk in the park with this company. The fitters, Paul & Zac were friendly, courteous & very respectful of my home. Minimal mess & always left the place tidy & most importantly safe. Very patient with my two very excitable dogs too ! The price for my windows & door reflect the company’s name perfectly – I had previously been quoted a lot more ! I can highly recommend Jason & his team – one very happy & warm customer.”

Ceri B

“I’m absolutely delighted with my new front door from Competitive Windows. The size of the door and frame was proving difficult to find a company who didn’t find this a problem. Jason visited and measured up, gave me lots of options on fittings, glass etc and true to his word it was fitted when he said it would be.
Andy made a great job fitting it an was extremely clean and tidy.
I’d have no hesitation in recommending them.
Thanks guys, for giving me a classy door, taking away my old one, which let in the draughts, and hopefully decreasing my electricity bill!!”

Maggie M

“They replaced a patio door and kitchen window for me great service and very competitive price.”

Terry S

“After all the hassle of trying to get planning permission to change my rotten windows and not getting anywhere, I decided to get secondary glazing. Jason was so helpful in getting it organised. Jason said it might be a few weeks but as soon as the order came in, he arranged for one of his colleagues to come round and get it fitted which only took a couple of hours. Even though it’s only been a couple of days I have noticed a huge difference. Thanks Jason and team!”

Helen L

“Not often I’m moved to wax lyrical about the service I’ve received but I’m delighted with the way Competitive Windows responded to my enquiry about a broken garage door. A late evening reply to my first message was a pleasant surprise and to have the repair completed by early the following afternoon was above expectations. Highly recommended!!”

Craig M

“Just had my new electric roller door fitted on the garage and it looks the business. The boys turned up on time, did a fantastic job and cleaned up after themselves, taking the old garage door away. First class service and would recommend them to anyone! Our neighbours have already been in touch with the boys to get theirs done!!!”
