  Gerry was very responsive and helped us out majorly in a serious situation on a Sunday. He was very honest and helpful, and fixed the problem q promptly. We definitely recommend them. Thank you Gerry!!

  We have just used three components of GMO Construction. We had our walkway extended, chimney repaired and restored and our roof de mossed. We found their workers very courteous, efficient and professional. The total project was completed under the quoted estimate and the clean up was spotless. If you need quality work done around your home, we recommend that you call Geraldo Migliorini at GMO Construction services first. Keith and Marion Holden

  Used this company twice and highly recommend it to others. They are knowledgeable, efficient, tidy and excellent workers. April 26/2020 - as an update to my review of 2 years ago. Had my roof sprayed again a couple of weeks ago (after 2 years!) and, as with the last time, the work was exceptionally well done. In addition, even though we are in the midst of a pandemic, yesterday I encountered a problem with a small leak in my roof and Gerry came back out within a day and fixed it completely. Seriously, I can't recommend this company highly enough!

  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.

  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.
