A damp spot in the hallway can come from a pipe inside the wall or from a fixture in the next room. Water that appears after a shower, dishwasher cycle, or sink use points toward a drain or fixture connection. Water that keeps spreading with every fixture off points toward a pressurized supply pipe.
We check both types of leak. We trace moisture from the hallway, cabinet, ceiling, or baseboard back to the pipe, valve, fitting, or fixture causing it.
An active leak should not wait. Water can travel behind drywall, under flooring, and into framing long before the original wet spot gets larger.
Water under the sink
Customers often report water under the sink, a wet baseboard, a stain on the ceiling, or a hissing sound behind a wall. A water meter that moves while faucets and appliances are off is another common sign. Some leaks leave a musty smell in a cabinet or closet before they make a visible puddle.
A loose supply connection, failed shutoff, cracked drain fitting, and damaged pipe can create similar marks on the floor or wall. We inspect the source because those faults need different parts, different access, and different repair work.
Pipe pressure test
We start the visit by checking the affected room, nearby fixtures, exposed supply lines, drain connections, shutoffs, and water meter. We use a moisture meter to map wet drywall, flooring, or cabinet material. We can also isolate a line and check system pressure, which commonly falls within a residential range of 40 to 80 psi.
A basic leak inspection and testing work often takes 30 to 60 minutes, depending on access and the number of fixtures involved. We can usually replace an exposed supply hose, valve, trap connection, or fitting on the same visit. A pipe behind tile, inside a wall, beneath a slab, or requiring an ordered part may need a separate repair visit after access is arranged.
Shutoffs, access, and pipe age
The condition of the shutoff and the age of the pipe affect the repair scope. An older angle stop may seize or leak when operated. Corroded copper, brittle plastic fittings, and worn supply hoses can mean the connected parts need attention as well as the visible leak.
Access also changes the work. A fitting below an open sink is different from a pipe behind a cabinet, tile wall, ceiling, or slab. We also account for replacement material, any part that must be ordered, and whether a permit or inspection sign-off applies to the repair.
Fixture model and access
We ask for the room and fixture where you first saw the water, such as the kitchen sink, upstairs bathroom, laundry box, or hallway ceiling. We also ask whether water is running now, whether the main shutoff or local valve can be reached, and whether a cabinet, wall, or crawlspace blocks the pipe. A faucet or appliance model number can help us match a cartridge, hose, valve, or connection. We can often find the model number on a faucet plate, under a sink fixture, or on the appliance label. The approximate age of the fixture also helps us plan for worn fittings. Call us at (512) 799-9083 before water behind a cabinet or wall spreads further through drywall and flooring.
