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

January 2016

Job has been completed to my entire satisfaction. Fit is better than ******* in the sense that the panels are much easier to remove. Noise reduction is better as well.

Thanks for the great service. It is refreshing to deal with a company that still provides such a high level of service at a reasonable cost.

IC Birmingham - Jan 2016 - 28th January 2016

Thanks for your exceptional service from the initial sales call, through to the informative and professional visit from both your representative when measuring the windows and the two gentlemen who came to install the windows.

The windows are fantastic and deliver on all the promises made, with the level of sound reduction achieved being beyond my expectations.

Please thank your team for all their efforts.

I thoroughly enjoyed fitting the windows, especially working with professional individuals who know their trade. Tim who was most helpful.

A pleasure doing business with you.

AR Redhill - Dec 2015 - 21st 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.
