"I communicated with Ron directly and he was determined to solve our insulation problems. He had to remove drywall in our entranceway and add in insulation where there were large gaps and air was getting in. He had a worker drywall and patch up the wall. The drywall worker did an amazing job!
Ron also fixed an ongoing issue we had in our garage ceiling that was causing our living room floor to be cold and drafty. He worked around our schedule and made multiple visits to our home to fix the issue. We are happy customers and happy to say that the problem is fixed. We were very pleased with Ron and his company and do recommend him highly.
