My wife and I were hesitant to use spray foam insulation, however Nathan and his crew re-assured is that the installation would be a seamless process. We were provided with an engineered certificate from Morrison Hershfield engineers saying that the foam was installed properly and to spec. From the first phone call we made to Foam Guard to the estimate they gave us (which was free) to the installation of the foam, everything was just SO easy! They were on time every time they came, we were charged exactly what we were quoted, and you can tell the owner Nathan takes pride in his work. We will be using Foam Guard and their services for our 3000 sqft new build cottage this summer! Can't wait for more purple walls! Would recommend to anyone in need of spray foam!
