N & G Windows and Conservatories Omdömen 

From start to finish the service received was excellent.
The finished product exceeded our expectations.
The whole team kept us updated, on site Aaron and then Gav were both neat and tidy, efficient, polite and professional.
We were listened to on what we wanted and they offered their expertise and guidance.
We are so pleased with the end results and can’t thank Nick and his team enough for not only listening to us and our concerns to installing our lovely porch

To N&G Windows,

We ordered a sliding door with a grey handle — I showed your salesperson exactly what I needed, and he marked it clearly on the order form. I stressed we needed the door urgently; we were quoted 4–6 weeks. Instead, we waited 6 weeks, only for the installation to be cancelled — twice — because the door wasn’t ready. On the third attempt, installation went ahead, but I immediately noticed the wrong handle had been fitted. I took photos and called your team while your installer was still here; you said someone would come — but nobody did. Repeated calls got us nowhere.

By this point, three issues had emerged:
• The wrong door handle
• Strong, persistent chemical smell
• Poor fit and gaps around the frame

Your Director, Jake Derry, arranged a visit — which was cancelled again. When he finally arrived, he claimed he couldn’t smell anything, dismissed the handle issue outright, and was unfriendly and arrogant. The tradesperson who came to fix the gaps could smell the chemicals and did what he could, but confirmed he couldn’t change the handle — that was for your company to resolve.

We then received a final invoice and a threatening letter demanding full payment or court action — and were told the correct handle would cost us an extra £400. We offered to pay the balance in full, withholding only £400 until these matters were resolved amicably. We ( my husband got fed up and decided to pay ) have now paid £3,000 — the full balance plus the £400 — yet the wrong handle and strong smell remain.

This has been an extremely disappointing experience. Repeated cancellations, poor communication, and a dismissive attitude from your Director are simply not acceptable. A "new car smell" analogy is not comparable — this is an interior door in our home, and the lingering chemical odour is not acceptable. I cannot recommend your company and I am deeply dissatisfied with both the product and the service received.

Last month I had new front door , and this month I replaced a very badly warped back door, all with this great company. Gavin was extremely good, great workmanship, very tidy, friendly. I recommend this company.

We replaced our old white patio doors with stunning, modern black aluminium doors, and the difference is unbelievable. They have completely transformed the room and given it such a sleek, contemporary feel.

We were so impressed with the quality of the work and the professionalism of the team that we also decided to replace our old conservatory roof with a new glass roof. It has made a huge difference — the space is now flooded with natural light, and everyone who visits comments on how amazing both the doors and the roof look.

From start to finish, the service was outstanding. Jake and the team were brilliant with communication throughout the whole process, and Gus did a fantastic job fitting the doors. The whole team were friendly, professional, and a pleasure to have in our home.

I genuinely couldn’t recommend N&G Windows highly enough.

JUST AVOID Really? Unorganised and stressful.

Unorganised office cancelled appointments, but don't even have a decency to phone me.
Taking time out of work as well Which have to make up.

When the windows finally got done fit is turned up only leaving 2 1/2 hours of daylight so I ended up helping them to get the job done before it got dark plus the fitter at to get a third work colleague to come and help.Unbelievable!
plus the fact that to make him feel the gaps in using my own filler.
WILL NOT Be using them again to finish the rest of the house.
Total shambles....☹️

I paid a hefty deposit in early July directly into N&G Window's account for a conservatory & was given a start date of 26/08/25 which was cancelled & re-scheduled for 1/09/25, this too was cancelled & rescheduled for 15/09/25. Enough was enough and not acceptable to me and I asked for a refund. I was called by the son/Surveyor confirming that they would cancel the job and requested my bank details for the refund. I heard nothing so I called again. He had not receive my email & I was instructed to send them again and then just waited. I called the office & was informed that there had been a meeting and that I may have to pay an admin fee, which was a shock to me. I did not know what was going on so I emailed Nick Derry the Proprietor, twice but was not afforded the courtesy of a reply to either. I called my bank today who confirmed the refund, done in early October but not a full refund. I did not get a copy of the survey, they failed to provide information for my Insurance company and the work never got off the ground; charging £500.00 for what? It would have been nice to have had a full refund. This family run company really do need to vastly improve their customer communications.
All I can say is Buyer BEWARE!
