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

December 2018

It is excellent and such a massive impact!!!

The service was also impeccable and the fitters very efficient and discrete. Will def recommend your company!

SL London - Dec 2018 - 12th December 2018

We would both like to thank everyone involved with the purchase and subsequent installation of our secondary glazing. We are both extremely happy with the product and its results (which exceeded both our hopes!).

One complaint, however, is that we both keep oversleeping!!!! Seriously, what a great result 😊.

SS Chorley - Nov 2018 - 5th December 2018

November 2018

I moved into a cottage with old style windows the cold from the metal frames and the draft from the frames was costing me a fortune in heating bills plus made for a miserable winter last years.

Today I have just had secondary glazing fitted and I'm thrilled to bits with the result. Graeme was such a pleasure to deal with and obviously knew his stuff when he visited. Peter who fitted the units was polite, cleaned up after he had finished and was respectful of my home.

I would highly recommend Black Knight to anyone wanting quality and a competent, reliable service.

TT Banbury - Nov 2018 - 29th November 2018

Firstly, may I thank the team - Graeme, Peter and Joe.
They all did an excellent job and on this, the first day, we are very happy with the quality of workmanship and the service provided.

Anyone needing secondary double glazing will get sent in your direction.

KT Oakham - Nov 2018 - 22nd November 2018

Excellent team you have and nice to see your son following in your footsteps. The windows are great and perfect sound proofing.
