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

October 2018

Thank you very much for arranging for the installation to be carried out so quickly. The chaps were very careful and efficient and we are very pleased with the unobtrusive design. It may be our imagination, but an hour after completion the room feels warmer already.

We have two neighbours who may contact you once they’ve been to see our panels.

The product is excellent and the installation was carried out in the most professional manner. Unfortunately, we are not good on names but please thank the installers for their quality installation with absolutely no mess- some of the single glass replacements were to say the least challenging.

AC Telford - Sep 2018 - 25th September 2018

I just wanted to take this opportunity to express my heart felt thanks for an outstanding service, as well as for such a superb product. Combined with such professional installation.
Rarely does the purchase of a single product have such an extra ordinary effect on the quality of daily life & well being to such a degree. However, in this instance the secondary glazing has provided near perfect 100% sound proofing. It has utterly transformed my office bedroom into a sanctuary of calm, of deep peace & quiet. The difference is incredible & the effects beyond my expectations & hopes.
Since installation of the secondary glazing I now no-longer hear any of the following since installation.
• No traffic noise from Kirkstall road.
• No Ambulances or Police sirens (which were especially intrusive)
• No House alarms (which can ring for hours)
• No Low flying Aircraft or jets
• No car alarms
• No music from rental tenants in the street
• No loud talking & conversations in the street at night
• No disturbance from the neighbour directly over the street at No.28 (late night parties).
Note: Have now stopped having to use ear plugs just to get a normal nights sleep.
My room has become a space in which its now a great pleasure to spend time in. I have needed this deep tranquillity ever since being bereaved & having moved back to Leeds. About three years ago. The stress & anxiety I used to suffer from in the past few years, due to noise nuisance has literally gone. Knowing that the secondary glazing is a permanent fix is also very re-assuring. Having broken sleep is awful but these concerns are all ancient history now.
My only regret is that I didn't have secondary glazing fitted two or three years before when noise was causing me even more distress & annoyance.

IR Leeds - Sep 2018 - 20th 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.

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!
