About GAD Plumbing

Plumbers for Homes on Low, Wet Ground

Mayo sits on a peninsula between the South River and the Rhode River, and about 40 percent of its area is water. Much of it is only about 13 feet above sea level. That setting gives a plumbing system less room for error. A sump pump that quits, a sewer line that backs up, or a slow leak under a floor has nowhere easy to go, and small problems turn into wet ones quickly.


GAD Plumbing, Heating & Home Improvement, Inc. serves Mayo from Tracys Landing, so we do not have a Mayo office. We come to your home, give you a price before the work starts, and offer free same business day estimates.

What We Do

What We Fix and Install in Mayo

Leaks, Fixtures, and Sump Pumps

Most calls start here. Our plumbing repair and replacement work covers the everyday failures and the ones that need quick action.


  • Water leak repair, burst pipe repair, and shut off valve replacement
  • Faucet, sink, toilet, and garbage disposal repair or replacement
  • Sump pump repair and installation, hose bib repair, and dishwasher and ice maker hookups

Clogged Drains and Sewer Lines

If water drains slowly, gurgles, or backs up into a sink or tub, the problem is usually past the fixture.



Pipes in Older Houses

If your Mayo house is older, the pipes may be too. Rusty or discolored water, falling pressure, damp spots on walls, and a water bill that keeps climbing are signs to have someone look. Our water and waste pipe services start with an inspection, then we recommend a repair or a replacement based on the age, material, and condition of the pipe.


  • Waste pipe repair and pipe replacement, including corroded galvanized steel
  • Leak repair and trenchless pipe repair
  • Pressure and flow tested before we call the job done

Water Heaters

Cold showers, rumbling tanks, or water pooling around the unit mean it is time for a hot water heater visit. A heater past about 10 years old is usually better replaced than repaired, and we will tell you which side yours falls on.


  • Tank, tankless, electric, LP or natural gas, heat pump, and boiler systems
  • Installation, repair, maintenance, replacement, and expansion tank installation

Pier Water Lines

Mayo has a lot of shoreline, and a pier line takes weather and tide that a house line never sees. Our pier water line repair and installation covers new lines to piers, repairs, hose bib service, and winterization.

Wells, Water Quality, and Gas Lines

Frequently Asked Questions

  • How much does a plumber cost in Mayo, MD?

    It depends on the problem, the age of the system, and the parts involved. We give you a price before work begins, and we offer free same business day estimates.

  • What do I do if a pipe bursts?

    Shut off the main water valve, turn off the water heater, move belongings away from the water, and call us. We respond around the clock to stabilize the problem.

  • Should I repair or replace my water heater?

    A repair makes sense for a failed part on a newer unit. A heater past about 10 years old, or one that keeps failing, is usually better replaced. We look at yours and tell you which makes sense.

  • Do you install or repair sump pumps?

    Yes. Sump pump repair and installation is part of our plumbing repair work, and it matters on low ground where water has to be moved out of the house.

  • Do you work on well systems?

    Yes. We service and replace well pumps and tanks and install well lines. We do not drill wells.
