"Sam and Chad did a wonderful job clearing the tub drain, installing new faucets in the bathrooms, installing a new shower head, and other projects. They double checked their work and answered any questions I had. While they need to come back next week to do a small part of the whole project, they were honest about what piece of equipment they thought would work, but would not. They were efficient, professional, and pleasant to be around. They made my day."
