Leading Chesterfield Windows Specialists 

This firm supplied us with a replacement conservatory in November 2017. We have been delighted with their efforts. The old timber conservatory was removed with a minimum of fuss and the newone replaced it in double-quick time. Everything seemed to slot into place with perfect planning, the electrics and the internet connection were dealt with without a hitch. The new building is exactly right—we wanted no frills, no complications, just a sturdy place to enjoy the warmth when it was there, and to keep out the cold when it wasn’t! Thank you to Terry and his crew. I’d recommend them any time. 

We received a fantastic service by Grassmoor Glass during our recent window and door installation. Professional in every way, no mess even hoovered for me! The units themselves are of the highest quality and the attention to detail in fitting is exceptional in our old property. I would not hesitate to recommend them to anyone. 

Excellent service from start to finish. Polite, efficient and knowledgeable at quotation and advice stage, fitted on agreed date. Fitters excellent, superb attention to detail and genuinelycared about the quality of their work.

Competitive price and high quality finish.

Would recommend in a heartbeat!

We used Grassmoor Glass to replace our windows, doors and fit a Supalite warm roof to our conservatory. We are extremely pleased with the results. Some of our windows were not straightforward but Scott and his team took extra care to make sure internally and externally they looked right. All the contractors used were professional and there work was of a high standard. We would definitely recommend Grassmoor Glass the whole team are helpful and really easy to work with.

I've used the company myself twice. Now just had them sort my dads house out. Very professional and understanding to individual needs. I will continue to recommend them.

Excellent service had new patio doors and back door fitted took old doors and windows away with them 

Left no mess

Apart from a hiccup with the promised lead time for installatìon, the door and window themselves and the standard of workmanship are excellent. The young men who did the fitting were a credit to the company and cleared away every bit of mess they had made .

Recently had a new composite door fitted,very happy with the door and the service was great too.Thankyou grassmoor glass

Great experience from the start, accommodating throughout every stage. Fitters were professional and the level of quality was great. I will and have recommended to family and friends.

Nice to see a family run business. They handled each job I've given them with care and shown a positively good way to do things. Did exactly what I asked first time.

The guy that came out to install the windows and doors was so professional and careful with his work.
