Insulating an Air Duct in Silver Spring, MD: Before the installers start any job in a customer’s home, they always lay out plastic all over the floor. The installers want to make sure they keep the floor how it looked before they came. The installers noticed a little problem during this job which was mold. We fixed this problem by spraying mold X before the spray foam. Many customers will question how do we spray Mold X than apply spray foam. The trick to that is the Mold X dries quickly which makes it easy for the guys to start spraying foam right after it has dried. This job resulted in another satisfied customer.
