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

July 2015

Many thanks to this exceptional company delivering outstanding service! I now have an amazing sound proof and great looking window! I have gone for the top range and very happy.Very good value for money and high quality work.

EDR London - Jul 2015 - 17th July 2015

I have recently gone through the sales procedure and fitting of secondary glazing for my home with two companies.

One a national household name, which was a disaster from start to finish with poor workmanship and late delivery.

By stark contrast I have been delighted with Black Knight. no pushy salesmen, they actually listen to what you want.

A good price, delivered on time and the workmanship is excellent. I cannot recommend they highly enough.

A brilliant company.

TH Tideswell - July 2015 - 4th July 2015

We just wanted to say how much we have appreciated the service we have received from Black Knight.

There have been a couple of obstacles to overcome with the installation of our windows but every one has been great and gone out of their way to come up with solutions.

From Graeme to Tim and the rest of the crew we can only say thanks for doing such a great job, keeping us informed and delivering the product you promised.

We are so grateful we came across your website.

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.
