Demoss Doctor Expert at roof cleaning restoration and treatments

After going thru the quote process with 3 well known contractors, I had pretty much given up on finding a reputable company I could afford, to repair my 75 ft rock retaining wall.

Fortunately, by chance, I came across GMO construction and, after the owner viewed my repair needs, i now have a completely repaired retaining wall. This wall was completed in just five days and the stone mason did an excellent job.

I am very pleased to have come into contact with GMO Construction and I will definitely use them in the future.

Our roof looks great. Thanks Gerry. I recommend GMO for roof treatments and maintenance.

Gerrardo and his wife removed most of the moss from my roof and then he used Spray and Forget solution to get rid of the rest of the moss. It had been a couple of months and there are no moss on my roof.

Quick, thorough, efficient, tidy, effective roof de-mossing. Very pleased with the results. Would use this contractor again.

Two thumbs up! Thank you Gerardo, for the excellent job! My roof looks better than ever. I was very impressed by your attention to detail and the high quality of your repairs. Thank you very much!
