Customer Testimonials

Fantastic service from DNA from start to finish. Everything explained and all questions answered. Left with a quote and no pressure to make a decision. Fitting was done quickly and efficiently by 2 friendly guys. Cheapest quote we got too. I would highly recommend them

Had our door fitted today, first class job, great fitters. Left everything Clean and tidy. Door is lovely so pleased with it. Highly recommended.

Had the pleasure of having new windows fitted throughout our house by the team. Very happy with the job and the look. Thanks again guys.

DNA Windows fitted two Windows in my kitchen and a new back door. They also replaced the fascia at the front of my house. All work was of a top standard, the lads were very friendly and helpful. Would highly recommend this Company

Two very helpful girls in the showroom helped me choose a door and gave me an instant estimate. Thank you.

I had half a dozen window people round for quotes and Andrew from DNA was one of the last. Pleasant man, not a salesman and there was no pressure. He quoted a good price around the same as other local companies but much cheaper than the likes of safestyle and Everest. The chaps that came to fit the windows and door were friendly, tidy and professional. They did a good job, worked hard and I'm very pleased with the results. I would definitely recommend this company.

Had all the roof fascias, dry verges and guttering replaced. The price was the best by far and the workmanship was excellent, top quality. The lads that did the job were very tidy and professional. I have recommended the company to a number of friends that's how pleased I was with the work. I was that impressed they will be coming back to do me a full extension next summer.

After worrying about having windows changed I decided to go with DNA. Good choice, there was no hard sell, everything explained clearly, excellent workmen, and a really good price and they look amazing. I would thoroughy recommend.

Very happy with our new front door it's classy and it's very high quality. The service was excellent Andrew and Suzanne were very helpful and thorough making sure I got the correct door type for my property. I felt important dealing with them. I was able to use their web resources to see how my door would look fitted. My door was supply only because we live In Scotland. The price was incredible for the quality we got. Local firms were taking the mick with their prices. My joiner said he had never seen such a secure door. It's rare to find a company now that has everything a customer wants great quality products, amazing price and genuine staff you can trust that make buying a product a delight. Thanks Mrs Littlewood

Thanks for the help in putting our cat flap in our french window. Best price and the service was just perfect. The installers were a great pair and they even adjusted the door to make it close better, which had been bad since we moved in, without being asked.. Thank you so much.

Used DNA on several occasions now, always very helpful and knowledgeable. Prices are very competitive. Staff are always polite and do a good job! would, and have recommended to friends and family.

Highly recommend Andy and the team. Used for windows, doors and most recently for our orangery. Always prompt at returning calls or emails, reliable workmen who turn up when they say they will! Friendly guys who get the job done

Had all of my upstairs windows and rock door fitted! Brilliant service and when the lock broke on my front door I messaged Andy at about 10pm and someone was here the next morning fitting me a temporary one until rockdoor sent out a new lock!
Good company and always friendly. Thank you DNA

Used DNA a couple of times. Excellent standard of workmanship and the price was really good. Would not hesitate to use again

We were extremely pleased with the work that DNA did for us. Very high quality products and very reasonably priced. Would highly recommend them. Very professional

Brilliant service, had a lovely Rockdoor fitted and from survey to fitting everything went smoothly. Lovely people to deal with, Andy was very honest and helpful and the girls in the office were very nice. Best price for a Rockdoor round here.

DNA completely transformed my ground floor living space reconfiguring and upgrading my old conservatory. All the glazing was upgraded including newly positioned french doors, a Supalite roof was fitted and an internal door and window were removed creating an openplan space which we can enjoy all year round. I highly recommend DNA and the Supalite roof system.
