Built on Reliability. Driven by Service.
Licensed plumbing and electrical for the Mississippi Gulf Coast — one local company for the two systems every home depends on.
Why Reliance exists
Every home on the Coast runs on two systems — water and power — and when either one fails, the search for someone trustworthy starts from scratch. Reliance Mechanical was built to end that search: licensed plumbers and licensed electricians in one local company, sharing one standard for how work gets quoted, done, and stood behind.
Owner Thomas Matthews leads the crew with a simple rule: do what you say, charge what you quoted, and leave things better than you found them. Whether it's a burst pipe at midnight or a panel upgrade before storm season, the phone gets answered and the price comes before the work.
