Very pleased with this company
I had some new windows and exterior doors fitted and the quality of the products seems very good. The company is easy to deal with and kept me informed. The installers, Kevin and Jason, were professional, friendly and polite. They came when they said they would, did an excellent job and tidied up before they left.
Quality products, fitted extremely well.
Extremely happy with my new front door, from date of placing the order to it being fitted I was kept informed.
The guys that fitted it were very knowledgeable and fitted my door, cleaned up and checked if I was happy before they left the property.
I would definitely recommend this company to others.
Efficient and knowledgable
Kevin and Jason did a great job and were efficient and speedy in replacing 5 windows, with the minimum of disruption. There was a measurement error with one of the window casings and they arranged for a new one to be manufactured and installed within 24hrs. Worked around scaffolding that was already on the building.

Really love our new bifold doors
Really love our new bifold doors. The whole team were helpful & efficient throughout. The fitters Steve & Tom were on time, polite & informative, discussing any minor asjustment options as work progressed. They also tidied up after themselves each day. Over all a great job. Thankyou
Thank you Crystal Clear
Crystal Clear provided a first class service from first enquiry at their showroom through to the final installation which was completed by a very professional team who took careful attention to detail. An excellent product which met all our expectations – highly recommended!
Good interior doors
The process from start to finish and everybody from the showroom staff, pre-install survey to the fitters were helpful and efficient.

Wouldn’t hesitate to recommend.
