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.

I was impressed by Grassmoor Glass from my first visit to their showroom, which is spacious enough to showcase their products without being expensively grandiose. I thought their quotation was very competitive and I was pleased by the way I was offered various options, with their price implications. Our conservatory was carefully designed to our exact requirements and we felt confident of the outcome.

Because our bungalow stands quite high we knew we would need a set of steps to gain access to the garden, but we felt that brick built steps would be too heavy, and we preferred decking. Grassmoor Glass does not recommend this, as it can become slippery and requires ongoing maintenance. They therefore suggested a new, non-timber product as an alternative. In fact they had never used this before and no effort was spared to give us the result we wanted. We are delighted with our new conservatory and would strongly recommend their service.

Absolutely excellent service, we've had 2 young fitters (Luke & Josh) in all week fitting our new windows and front door, can't rate the service highly enough, they were fantastic and have done a brilliant job
