What Our Customer's Are Saying About Us...

October 2015

We have just had two units fitted and I can highly recommend them for looks and efficiency.

The technicians who did the fitting were very professional in their work, and there was not even a speck of dust around when they had finished the installation. They even removed their boots when they entered the premises. Something that some workmen forget to do!!

All in all a most satisfactory transaction.

GC Lincoln - Oct 2015 - 29th October 2015

I've been meaning to thank you so much for the wonderful job that you, Tim and Joe have done on the new windows. I'm just so impressed with your team! I've been praising Black Knight to anyone who will listen - great design, work done on time, excellent quality product, all mess cleared up! To say nothing of lovely people. It's been a real pleasure to have you doing work on the house.

Of course you'll be welcome anytime to have a look at your work!

CP Sheffield - Oct 2015 - 27th October 2015

I am very happy with the whole experience of dealing with your company from when I first made contact to when the expert fitters had finished. I had struggled to find a suitable solution for road noise coming through my large 6 panel bay window in the living room. I have plantation shutters and was told by another company that secondary glazing not an option. However I now have secondary glazing behind my shutters and you would never know. I decided to go for the Stadip sound reducing glass with lift-in, lift out glazed panels. The fitting team took down and refitted both the shutters and the blinds which was brilliant. In terms of noise reduction from the busy road I am very happy with the products performance. It really does make a difference and the room is a haven of tranquillity and also much warmer. I will now be able to put up guests in the room if needed which would have been impossible before due to the noise. Thank you again.
