Report
20 years ago GRM green roofed my house and recently, when I wanted to hard-roof a difficult, sloping, previously glazed roof they came back to do the work. Once again, the products (Bauder) were first class and the quality of the work was as good as ever. The team on the roof were led by one of the guys who'd done the original work and included two of his family members, so besides a wealth of experience there was also great continuity. As well as giving good and timely initial advice, GRM were flexible and worked round tricky weather conditions and difficult access to deliver a roof that was far

Report
One of the drivers from this dump drove so close to the back of me that we were almost rubbing bumpers up Colchester road, the speed limit was 40 and I was already doing 42 so I wasnt going slow and I had a cue of people in front of me. He then went on the inside lane, continued to shout abuse at me and stick his fingers up at me while I had my 6 year old sister in the car. If my sister wasnt in that car then he would have been in some serious problems with me that would make him regret his decisions. Do not go with this company if this is the sort of dirty muppet who will be coming into

Very pleased with both the price of the job and how the job was done. Polite workers who cleared up after themselves. Would definitely recommend
