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

October 2015

Honestly, the job was above expectation. The guys were hard working and explained very clearly how it all worked. The product is first class and looks great. You can hardly notice they are there. I slept wonderfully last night and I think we could not have asked for a better result. The sound reduction is very substantial. I am most impressed by the elegance of the design.

From start to finish, it has been a real pleasure dealing with you and your colleagues. Professional, friendly, accommodating and was clear to me that everyone takes pride in there responsibilities.

AB London - Oct 2015 - 25th October 2015

The product is brilliant! I can hardly hear a thing even when lorries or motor bikes go past. Didn't sleep v well last night. Too quiet! Silence has an ambience & hum all of its own. Or maybe it's my ears! The guys who fitted the product were great & v tidy.

Many thanks to this exceptional company delivering outstanding service! I now have an amazing sound proof and great looking window! I have gone for the top range and very happy.Very good value for money and high quality work.

EDR London - Jul 2015 - 17th July 2015

I have recently gone through the sales procedure and fitting of secondary glazing for my home with two companies.

One a national household name, which was a disaster from start to finish with poor workmanship and late delivery.

By stark contrast I have been delighted with Black Knight. no pushy salesmen, they actually listen to what you want.

A good price, delivered on time and the workmanship is excellent. I cannot recommend they highly enough.

A brilliant company.

TH Tideswell - July 2015 - 4th July 2015

We just wanted to say how much we have appreciated the service we have received from Black Knight.

There have been a couple of obstacles to overcome with the installation of our windows but every one has been great and gone out of their way to come up with solutions.

From Graeme to Tim and the rest of the crew we can only say thanks for doing such a great job, keeping us informed and delivering the product you promised.

We are so grateful we came across your website.
