We knew that our 80-yr-old house in La Grange Park, Illinois, had a plumbing problem but we didn't realize the specifics until Melvin Plumbing did some excellent detective work. The extensive repair work solved the problem and was worth every penny we paid. We've been recommending Melvin Plumbing Services to our neighbors. The Melvin team is pleasant to have around the house -- the workers wore booties to protect our hardwood floors and carpeting, and they cleaned up after themselves. Five stars, recommended without reservation.
