Mark gave me a very reasonable quote to install 2 bathroom exhaust fans/lights. He was on time for the estimate, cheerful, and professional. He was not pushy and allowed me time to make my decision. Six months later (after finding the right ones), I was final ready to have them installed. Just a quick email and Mark was there within a few days to install them. He also replaced a very old and corroded garbage disposal - not an easy job. He was conscientious about protecting the area he was working in, efficient with his time, and cleaned up thoroughly after himself. I would not hesitate to hire him again and would recommend him to be best friends and family members.
