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

September 2018

Matt visited Carlton yesterday to meet the client. They are very impressed with all of your works they love the doors especially.

Thank you for your efforts on this project Graeme it’s very much appreciated, and we understand it wasn’t easy at all.

SJ London - Sep 2018 - 19th September 2018

July 2018

We have used Black Knight twice over the last 2 years.

Once in a Regency property where they very successfully installed near floor to ceiling secondary glazing, matching the colour of the paint work beautifully and blocking out nearly all the noise from a nearby road. And again very recently in our new home, which is actually a very old home.

It is in an exposed position on the coast and with strong storms and gales we struggled last winter to keep the cold out. I've every confidence that this winter will be much easier.

I thoroughly recommend Black Knight for their brilliant customer service - Graeme is a God send!
