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

May 2016

I just wanted to say that the Windows have been completed and we are very pleased with the installation.

The fitters have been excellent in their efficiency and workmanship. I would also like to thank you for your understanding and flexibility during the process.

All issues and delays, none of which were caused by your company, have been dealt with with patience and calm consideration which we appreciate.

I am very pleased that I chose Black Knight and would have no hesitation in recommending them to anyone. You have acted like an advisor throughout and if we decide to have further secondary glazing in the house we will return to you without hesitation.

Having had the secondary double glazing in place for just under a year now and with winter finally over I am very pleased to be able at last to send you the promised feedback and to once again thank you for your excellent service.

Firstly the whole process from first contacting your company, to fitting the secondary double glazing panes has been fantastic. Highly professional, efficient and a high standard throughout.

Secondly, although it was not the primary aim of having the secondary glazing fitted nonetheless the outside noise reduction is is very significant. I live in a busy part of the city with its fair share of typical and expected noise. But I must say that once the panes where in place all that noise has almost completely disappeared.

And finally, the main reason I had the secondary glazing installed is that I live in an old Victorian building with very thick walls and original wooden sash windows, who look beautiful but are really not very useful when it comes to keeping the drafts and cold out.
Having the secondary double glazing on all 10 windows has kept the average temperature inside my flat (which has a large open-plan lounge/kitchen with a high vaulted ceiling) by at least 2 degrees higher than last winter, before the secondary glazing installation. And also it doesn't sound like much, nonetheless it meant I didn't have to heat the place up as much as I did last winter and the place stayed draft-free all winter. An all that at a very reasonable price too!

We are delighted with the new secondary glazing in our lounge. It has been beautifully made and fitted.

It looks really good, but it is early days for saying what difference it has made to the warmth of the room - we'll have to let you know!

For now, we want to thank you for visiting, explaining, demonstrating and quoting and for the professional job done by your joiner. He also was punctual, pleasant and efficient. The window was fitted quickly but with great care and my husband was given clear cleaning instructions.

Many thanks to you all for a really lovely job.
