Once every 10 or so rainstorms, water drips onto my dining room floor. Over 7-plus years, various contractors and handymen have tried to stop it, and failed. Wayne came by, made a nearly instant diagnosis, and promised he'd be back the next afternoon to repair it -- in less than an hour. He came back as promised, right on schedule, did his thing, and thoroughly tested it with my hose. Even cleaned out the gutters so the hose water wouldn't soak my deck. Now two rainstorms later, no leak. After 8 more storms with no leak, I'll come back to Thumbtack and give him FIVE stars!
