Homes built on a slab have water pipes under the concrete. A slab leak shows up as a warm floor, the sound of running water, cracked flooring or a rising bill. MJA Plumbing and Heating locates slab leaks without guesswork and repairs by spot access or by rerouting the line.
A real person picks up day or night, and an emergency plumber is dispatched immediately.
You get the price in writing before we start. No surprises on the invoice.
Most repairs finish on the first visit because the parts are already on the truck.
Our plumbers live and work in the communities we serve and know the local water and winters.
Shoe covers, drop cloths and a tidy job site every time.
If a repair we made fails, we come back and make it right.
Rerouting is often cheaper and less disruptive than breaking concrete — we will quote both.
