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

June 2015

Tim has finished with the installation of our new window.

All I can say is wow...What a difference and it looks stylish.

Please can you send us the invoice, so we can arrange payment.

Tim was very friendly and professional. He cleaned up after himself, which we appreciated. He really is a credit to your company.

It was a pleasure doing business with your com

I wanted to thank you for the way you have done business with us. From the first enquiry to the final installation you have been efficient, friendly and courteous. We are very satisfied with the product and the noise reduction is very noticeable - which is exactly what we hoped for.

We were particularly impressed with your installer, Tim. He was very considerate, kept us in the picture with what he was doing, did a first class job as far as we can tell and left the place cleaner than how he found it!

Please pass on our thanks to him.

DH Sutton Coldfield - May 2015 - 28th May 2015

We are very happy with the secondary glazing and the service provided by Black Knight (professional & friendly all the way from the inquiry to the quick and clean installation). The windows look smart and most importantly they make significant difference. Since we moved to our new home, we were not able to sleep in our master bedroom because the noise coming from a street was too disturbing. Now we are back to our master bedroom and we can sleep comfortably. I have to say Black Knight did a great job and I can recommend them highly!

Thanks for a superb job; we are very happy with the quality and the difference it has made to our home.

Look forward to talking again in the near future when we come to tackle the next lot of windows!

Thank you very much!

I've just transferred payment for your invoice online.

Thank you very much indeed for the excellent service we've received. Graeme was a superb point of contact throughout.

As discussed I'd be grateful if you could please provide me with a quote for further secondary glazing for my lounge windows.

Kind regards

I have got the secondary window installed in the bedroom for Ramsay House.The company that did it was Black Knight secondary glazing. We decided to go with them after doing a lot of research and going to many window companies.(Some window companies said they cannot do it). I can say Black Knight did a first class job and I can recommend them highly.They are very professional and give you the best service.

They charged me around £1100- 1400 depending on your needs for the secondary window. I am very pleased with the service and they have high expertise in the business.The Director Graeme is familiar with Ramsay House and he went out of his way to help us. He is very knowledgeable and accommodating.
