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

October 2014

Thank you so so much for you and your team's skill, attention to detail and professionalism in designing and installing our secondary glazing in the bedroom. We are very happy indeed with the results.

They look amazing and you have managed to make them blend into in our 18th century house. The sound proofing effect is amazing - until we get used to it is is almost "too quiet"!

Seriously, thank you. Please pass my thanks on to the installation team who came yesterday. We are looking forward to getting the lounge done on the 15th.

Also, if you can tell us how much it would cost to have the 3 second floor bedroom windows done that's be great

KL High Wycombe - Sep 2014 - 3rd October 2014

Window is stunning. Very impressed.

RC Manchester - Aug 2014 - 3rd October 2014

Many thanks for the work you and your team undertook for us recently.

We're delighted with the quality of the work and are grateful for the recommendations you made around the best choice of products. Your vast experience here was invaluable and really came across. We have 3 front facing rooms on a busy main road, whch can now be used as bedrooms upstairs and a lounge where I can finally hear my television easily, with no road noise! The draughts have disappeared too, and with the installation being in summer, I've noticed how much warmer the rooms are this year. I can't wait to see the improvement on our previously sky high gas bills this winter.

Finally, we're really grateful for your help in making sure we were able to achieve what we wanted within a sensible budget, without compromising or cutting corners. We would of course be happy to use Black Knight again, and would have no hesitation in recommending you.

Thanks to you and team! Fabulous job. Why didn't I have it done years ago!?

My dad loved them! He said they were just leaving but agreed to come back in to talk him through mechanism. He thought they were both lovely guys. Couldn't be happier with job!!! Feels like a proper flat now. No longer feel like I'm sleeping on junction road! Noise was so bad before. Now it's almost silent. Completely perfect! Also the look I was so worried about is completely fine. Really am delighted with end result.

Couldn't be happier! Please thank your team on my behalf! Graeme was a pleasure to work with and your team were super nice to my Dad who wanted them to talk him through mechanism when they were just about to leave!

I paid the amount, in full this morning. Should show up in your account in next couple of hours.

Super job! Can hardly hear the main road now! And I needn't have worried about aesthetics. It looks fantastic-just as Graeme promised!

CO'S London - Sep 2014 - 9th September 2014

On time, as promised - and superb support from initial contact to final delivery.
