We offer a 10% labor discount for new customers, plus for senior citizens and military veterans at all times. Although our work schedule is Monday thru Friday 7:00am to 3:00pm, we offer 24hr emergency service and free estimates at any time. Our quotes are locked in prices, but if we complete the work in less time, the cost of the work becomes less.

"We had mold that another company removed. Todd and Dave at Booth Home repair were very professional during the estimate phase and pointed out a few areas the other three contractors did not see. They were punctual, friendly and had a reasonable quote. They started when they said they would, and treated our house as if it were their own. We are more than pleased with their finished work and would recommend them highly."
