No Nonsense Windows 

My experience with NN glazing was very bad.
I had windows installed down stairs without lintel which caused the bricks to crack since it was carrying the weight of the top floor.
Windows and fitting are poor quality allowing cold air in.
For the kitchen the sale person ( Jazz) asked us to buy a kitchen fan and to bring it to the factory to get the size of the glass cut, they lost the fan and after many emails and phone calls not willing to resolve the issue.
When I communicate with the company regarding 2 faulty handles it took them a month to send some one to fix the problem although it was a downstairs window and we were left with an open window for weeks .

Excellent service from Non-Nonsense. We had two new external doors fitted. The service was great and Andy was very apologetic for the delay in delivery of the doors.

I had all my (7 Inc a bow) front windows replaced by 'no nonsense ' Andy has been in the trade for years. The job and timeline went just as he said. Martin the lead fitter and Andrew, did a great job and finished in the estimated time. They are pleasant and efficient.
No nonsense were not the cheapest of the companies I asked to quote, but Andy turned up on time, sent a quote in a reasonable time and the profile they use is better than some of the competition.
I would recommend them.

Quality of product and fitting was extremely high. Company liased throughout the whole process. Highly recommended.
