Walt was very friendly, knew his job and explained to us exactly what needed to be fixed and we TRUSTED him. I mean pictures do not lie folks. He helped us in the process of resurrecting our crawl space into a space that even our heating and air guy commented was a cadillac crawl space and he did not mind working on our furnace under there now. we could not be more pleased with the end result and CANNOT start waiting to feel BETTER. My husband is a disabled vet with numerous health issues and I am looking forward to him feeling better.THANKS Basement Doctor.
