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

September 2016

Black Knight carried out quite a large project at my house, secondary glazing several large stained glass windows in my house. The experience from start to finish was great, the whole process was smooth and very professional and the results were fantastic. I would highly recommend them and would have them back tomorrow if I had any further work for them.

The company is small and with that comes a very personal service which you simply do not get with the larger companies. Black Knight care about every single aspect of the customer experience, from listening to what the customer wants and discussing how to achieve it, to getting the job completed and ensuring they do a good job. The whole team from the office staff to the Graeme the director who comes and consults with you to the team of fitters, they all work to a very high standard and have an excellent level of professionalism, they take incredible pride in their work. I honestly cannot sing there praises enough. Graeme and the team are super and we have recommended them to others.

The work was done quickly and now we have a much warmer and quieter house thanks to the team. They went to the trouble of replacing some old plain window panes for us as well as resolving an issue with rotten timber frame, taking all the worry and stress away from us as clients.

If you do not use Black Knight for your windows you have seriously made the wrong decision. We personally found the larger, more well known companies to be pushy, very expensive and we just did not get the same level of customer service and consideration. I loved everything I saw on the website and then once we spoke in person with Graeme we knew we wanted to work with them and my word we have not been disappointed at all. So many people comment on how lovely our windows look and how we have managed to keep the character of the original windows even though they are secondary glazed, they are very discreet and do not interrupt the view of the original window. 10 out of 10

Outstanding windows, service, advice and, price.
I am really pleased with the way Black Knight team has worked in every step of the installation of my secondary glazing units.

Everything appeared to go well with the installation of the three units, and the results are very pleasing. The difference in just the sound insulation alone is most noticeable..

It has been a pleasure to do business with you and you will certainly be well recommended by us.

The windows are great!

My ear plugs are gone & it's made a huge difference.

The joiners did a wonderful job and the noise levels are so much better.

I so wish we'd done this years ago so that we could have benefitted from this vast improvement but you live and learn.

All in all a brilliant job all round and the colour of the paint finish is spot on.
