Mr Bannon

Mr Bannon was recommended to Onyx Windows himself and would both use us again and recommend us himself.

From the initial inquiry to the final installation, the whole process was very efficient and skilful. Very happy with the end result!


Mr & Mrs Thompson

Mr and Mrs Thompson were over the moon that Onyx personnel were courteous and professional throughout.

Our new conservatory is GREAT and we would like to thank all involved. We would not hesitate to use Onyx for any future works.


Mr & Mrs Wood

Greame fitted our windows with great professionalism, taking great PRIDE in the work he was doing, which I can honestly say is rare these days.

The staff were extremely helpful from the outset, assuring us of the companies attention to detail, and GOOD workmanship, which is ultimately why we chose Onyx Windows.


Mrs Allsop

All the work was carried out efficiently. I would never use anybody else as all the people I have come into contact with at Onyx, have gone the extra mile for me.

I always recommend Onyx to friends, because from START to FINISH I have always had a friendly, professional and quality service.


Mr & Mrs Arman

We are delighted with the product – our new windows look good and we can already tell that they insulate better against sound and heat loss.

The fitting team worked tirelessly, often in bad weather and their work ethic could not be faulted. We are impressed by their attention to detail and they left everywhere clean and tidy. Thank you, especially to Greame who worked like a Trojan!


Mrs Payne

We are delighted and can honestly say a professional job well done.

One small error rapidly corrected therefore no complaints and a very pleasing outcome.


Ashby Court - Retirement Accommodation

Ashby Court provides sheltered accommodation for retired people. It is a three storey building with fifty apartments, and numerous communal areas, and the task of replacing all our hard wood windows with UPVC was quite daunting.

Onyx Windows were on the case right from the start, and with meticulous planning and excellent communication,

the job was executed without a hitch.

The fitters were pleasant to work with, were considerate towards the residents, and always left each apartment clean and tidy when they had finished.

A job that had been estimated to take 6 - 8 weeks was finished in 5, and I would have no hesitation in recommending Onyx to anyone who had a similar project to undertake. A total of 230 windows and 12 patio doors were replaced.
