I had Mike come and do the rim joists in an old bungalow built in '56 with the intention of putting in R14 Roxul on the walls. After dealing with the City of Edmonton and my permit hassles, I realized R14 wouldn't meet code. So I called Mike back to do the walls with 3" Wall-Tite Eco 2 lb closed cell foam. Mike did a great job protecting my personal items from overspray and did a perfect job on the walls. I would not hesitate to recommend Mike for spray foam application.
