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

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!

Excellent company to deal with. Friendly staff, great product and they did what they said they would do when they said they would. Secondary glazing has made a real difference to the sound coming into the rooms. Would definitely recommend!

WOW!! And that's without actually testing the noise performance yet. Now I am actually WANTING the noisy gardeners to come with the strimmers, mowers and leaf-blowers. Why I am saying "wow" before even knowing that side of things is because they LOOK and FEEL fantastic. And your fitters (that label doesn't seem grand enough to describe them) were a couple of the nicest guys I have had the pleasure of meeting (I include your good self in that coterie of happy new acquaintances). Seriously though, what a beautiful job and a painless experience (Mr Payne gave me no pain). And please pass on my feelings to the guys.

I will let you know how the sound side works out. I doubt I'll be disappointed. And I'll sort out your invoice by bank transfer in next couple of days.
