I had insulation replaced last February by Insta-Insulation and the workers really performed a good job. There was no problem in the summer and I can really feel the difference. As the cold weather approaches, I notice a black spot is appearing in the front door ceiling. Apparently, the insulation on that section of the attic is disappearing. I phoned Insta-Insulation right away and sent someone to check it.
Thanks Joe and Trevor for fixing the problem.
I will for sure recommend Insta-Insulation to friends and relatives.
