Patchmasters is a drywall repair company specializing in all types of drywall repairs and other jobs involving drywall. We Fill a Crucial Gap in the Home Improvement Industry! When trademen such as plumbers, electricians, roofers, and HVAC professionals come into a home to do installations or repairs, they do what they were hired to do, but unfortunately often leave homeowners with gaping holes in their walls and ceilings. The next step is to find highly-trained experts to perform small drywall, plaster, and sheetrock repair jobs, but most contractors simply won’t take on jobs that small.
