What our customers say
Naz did a great job replacing the hinges and double glazed sealed units on my UPVC windows after they became foggy. Installation was quick and coordination with him was easy. The pricing was very reasonable.
Naz manufactured and installed all of the doors and windows in my renovated terraced house. Him and his team did an excellent job, on time and with great communication. Post installation Naz is always available for questions and tuning of windows/doors where needed. He is pleasant and professional and I couldn’t recommend him enough!
We had had a rotting wooden window in our bathroom since we moved in three years ago. Finally, it was seconds from falling out of its frame, and we checked out the reviews of nearby glaziers, which is how we found NN Double Glazing. Nobody can be this great, and so reasonably priced, I thought, but we decided to give them a go. Naz came over and quoted a great price, and then fitted a beautiful new window, far more suitable for a tiny bathroom than a wooden one. He and his colleague were all done in about 2 hours, were a pleasure to have around, answered all our questions, no matter how silly we thought they must sound, and tidied up after themselves. Naz is clearly a perfectionist and he won't leave you until he believes everything is exactly as it should be. We can't recommend these guys highly enough. There aren't the words. Just, if you need new windows, don't bother looking anywhere else. Or do - get three quotes, as is sensible - and then use NN.
Naz was very communicative and professional. He came out to replace a hinge and they were very affordable compared to the competition. He did a quick and good job. We are very happy with their service.
Naz replaced our bathroom window at a reasonable price and with no unnecessary delays or fuss. He was prompt in his communication and a professional throughout. Recommended and would use again.
