Our backdoor is still not finished 6 weeks after installation. We have chased repeatedly over the phone and even been into the store. We keep getting told we are going to be called back though this never happens. I would have put the rating at 1 but the guys doing the fitting were really nice. Can't help feeling that the reason we're getting fobbed off is because we paid in full. Really poor service that has cost them the extra work I now have.

Nightmare from start to finish. left us with a non water tight extension. Bricks outside not pointed, walls not straight. Wires hanging out of the walls, spot lights hanging down cracks everywhere. Total rip off stay away at all costs. Will take your money then go into administration and trader under a similar name. Should be illegal. Dont know how they sleep at night. Full of empty promises.

A great Job from DNA, most importantly the 2 lads that came to do the job were very respectful of our property and were very clean - very happy with our new windows and would recommend DNA anytime.

THIS COMPANY HAS GONE BANKRUPT AND SHIFTED DIRECTORS. 10 YEAR GUARANTEE ISNT WORTH THE PAPER ITS ON! Steer clear!

Beware! This company uses pictures of other company's work and advertises it as their own. Advertised a garden room which was in fact done by Oakwood Garden Rooms in Leeds. Worth verifying personally any previous works this company claim they have carried out.

This company obviously have such poor quality of work they have to use others companies images to put on there website and claim as there own work!

Very disappointed, one window has been left with a cold wind coming through, rain coming in and the internal corners of the window turning black, and the seal on the front door is coming away, a fitter arrived within a couple of weeks of the first complaint and said his van was broken he had no ladder with him, but didn't want to not turn up, so he came over in his own car and said he could see potentially what the issue was, he was the one who signed off my job as being to standard, he said he would come back with a ladder I didn't need to be in, he didn't check the inside of the window, roll on 12 months later, still nothing.

I rang them again and they said they couldn't find the complaint on the system and they would send someone else out, another fitter came, said he could see what the issue was and he would be back within a couple of weeks, also with a new seal for my front door, we are approximately 6 weeks on and still nothing, nowhere near good enough, extremely poor after care.

Products nice, price ok most of the guys professional and pleasant. But, they ( office too) can't all get their stories straight when they dont show up. You always have to call them, they never email when they say they will. If the van did break down a call would have been nice to tell me! Oh sorry or are they ill? Ordered a window incorrectly, told my plasterer " don't do the reveals til we've done the window". Nearly 3 weeks still waiting. THANKS A LOT! So from my experience not recommended

The new SupaLite roof system has just been completed and has transformed my conservatory. The quality of the product is excellent and I can't praise Craig, Jordan and Jason enough for their craftsmanship and friendly manner. I would highly recommend this company.

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.

Highly recommend, Andrew and the team are very helpful and professional. We had new windows and a door fitted and are very happy with the high standard of service they provided. I always pass on their details to others.
Debbie Cornwell
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.
Carolyn Leebetter
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.

Sam Bailey
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
Eve Coles
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
Sarah Booth

Christine Littlewood
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
Gill Palin
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.
Gary Riley
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.
Richard Sayers
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.
Margaret Hall
Two very helpful girls in the showroom helped me choose a door and gave me an instant estimate. Thank you.
