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

January 2015

“What a pleasure it has been to be a client of Black Knight.

The customer service is exceptional, from initial contact, followed by a very detailed quote with all options of costs, timings aimed at my convenience, and skilled installation as well as a clear demonstration of how to operate their easy clean system.

It is a very competitive market and there are possibly other firms which might quote lower. However Black Knight is not only excellent value for money, their integrity and conscientious service will be very difficult to beat”.

We're really pleased with the windows, they look great and we're already feeling the benefit warmth and comfort-wise. We've not had a single bit of condensation since the installation and the house is generally a lot warmer! It's fantastic and novel for us! I don't think it will be long before we'll be back for the remaining two windows to be done!

MB Yorkshire - Dec 2014 - 15th December 2014

I would like to commend the fitters who did an excellent job and worked very tidily, cleaning everything up before leaving. The secondary glazing itself also looks very professional.

I am pleased to say that the new secondary glazing is making an appreciable difference, even though Graham explained it would be quite challenging to obtain such a result, given that I had already got secondary glazing. The new installation is fully meeting my expectations.

All in all, I would like to commend your company's professionalism and the quality of its product. I would have no hesitation in using it again, should I need to do so, or in recommending it to anyone else.

RC Wellingborough - Dec 2014 - 15th December 2014

We have now had your new secondary glazing for two weeks and we have to say the outside noise reduction is superb, far better than we were expecting.

We know how challenging it was to fit the windows on a round bay yet you managed it perfectly.

Despite being Leeds Utd supporters (!!) your fitters did a great job, making good all round the new windows and leaving the room clean and tidy.

We would like to thank you for all the time and effort you put into our new windows and we can now look forward to peaceful nights sleep.

R&J P Brighton - Dec 2014 - 10th December 2014

Thank you for your help at every step of the process. Black Knight always returned calls promptly and were clear on both product and price. A fantastic company to deal with and a great product.
