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

December 2015

I have a tricky arched window that several companies refused to take on. However, David at Black Knight quickly replied to my email to explain they could solve the issue. This was followed by a phone call from Graeme who explained different options to me and possible solutions.
I was deeply impressed with both the quick response and their determination to see the job through. Graeme arrived to take measurements the following week, and I trusted him immediately with the task at hand. His colleagues arrived just a few weeks later to fit the window; the job was not easy, but finished to the highest specification.
I am absolutely thrilled with the product - I never thought Secondary Glazing could look so stunning. It does not detract from the Victorian arched windows and the quality of the product is remarkable.
Most importantly, the room is now soundproofed to an extent that I never expected. I would thoroughly recommend Black Knight to anyone seeking secondary glazing.

EC London - Dec 2015 - 8th December 2015

Just a quick email to say thanks. We are so impressed with the quality of the secondary glazing we had the best sleep since moving in last night. It's absolutely brilliant.

The guys have done an outstanding job, they were unable to block up the vents with the acoustic wool in the living room because the blinds were fitted to close but did do the vents in the study. Because it has made such a difference in the study would you be able to let me have some of the wool so I can get the blinds taken down and I'll put the wool in myself because that on its own makes a vast difference and I forgot to ask them to leave me some out.

We are very happy, Boys were a pleasure to have in my home. So tidy and now sitting in the lounge with no car noise and no draft, and a large glass of red wine to celebrate. Our next door neighbour has already been in to see what we had done and was very impressed with the finish.

I can only thank you for a job well done.

Just wanted to say thank you to you and your team. My bay window looks great.

CB Nottingham - Oct 2015 - 30th 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.
