Stop Leaks Before Cabinets Get Ruined

Marble Falls Plumbing LLC repairs kitchen and bathroom sinks throughout Marble Falls, restoring drainage and stopping leaks under your cabinets.

When water starts pooling under your sink in Marble Falls, it usually means a worn seal, loose fitting, or damaged drain line is letting water through where it should not go. You might notice dripping when the faucet runs, puddles forming around the base of the cabinet, or a musty smell that shows up after doing dishes. Marble Falls Plumbing LLC identifies where the water is coming from and replaces the parts that have failed, whether that means tightening compression fittings, replacing corroded tailpieces, or swapping out deteriorated gaskets that no longer hold a seal.


Sink repair also addresses slow drainage caused by trap buildup, improperly pitched drain arms, or failing basket strainers that let debris pass into the line. Once the faulty components are replaced and connections are retightened, water flows cleanly through the drain without backing up into the basin or seeping onto the cabinet floor. The work prevents further moisture exposure to particle board and cabinet frames, which can swell and rot if left wet for too long.


If your sink is leaking or draining poorly in Marble Falls, contact Marble Falls Plumbing LLC to schedule a repair and stop the problem before it spreads.

What Happens During a Typical Sink Repair Visit

When you call for sink repair in Marble Falls, the plumber starts by checking the supply lines, drain connections, and trap assembly to find out where water is escaping or where the clog is forming. Tools like basin wrenches and slip-joint pliers are used to loosen old nuts, remove corroded parts, and install new washers, gaskets, or tailpieces that match the existing setup. If the basket strainer is loose or cracked, it gets pulled out and resealed or replaced so water stays inside the drain instead of leaking into the cabinet.


After the repair is finished, you will see water drain quickly without standing in the basin, and the area under the sink will stay dry when the faucet runs or the disposal operates. Cabinets that were damp before the repair can begin drying out once the source of the leak is eliminated.


Repairs also include checking the P-trap for debris, testing all connections under pressure, and making sure nothing drips when the system is back in use. The work does not include replacing faucets, garbage disposals, or countertops unless those components are part of a separate service request, but it does restore the sink to normal function and protect the cabinet structure from ongoing water exposure.

Questions People Ask Before Booking Repairs

Homeowners in Marble Falls often want to know what causes leaks, how long repairs take, and whether older sinks can still be fixed without full replacement. These questions help clarify what to prepare for and what the repair will actually address.


  • What causes a sink to leak under the cabinet? Leaks usually come from worn washers, loose slip nuts on the drain assembly, cracked P-traps, or failing putty around the basket strainer. Over time, these parts degrade from water exposure and need to be tightened or replaced to stop the drip.
  • How long does a typical sink repair take? Most repairs are completed in under an hour, depending on what needs to be replaced and how accessible the connections are. If the cabinet is crowded or the trap is heavily corroded, it may take slightly longer to remove and reinstall parts safely.
  • Why does my sink drain slowly even without a visible clog? Slow drainage often results from buildup inside the tailpiece or P-trap, a partially blocked vent, or a drain arm that slopes the wrong direction. Cleaning the trap and checking the pitch of the drain arm usually restores normal flow.
  • Can an older sink be repaired or does it need replacing? Most older sinks can be repaired as long as the basin itself is not cracked and the mounting hardware is still intact. Replacing drain components, seals, and supply lines brings the sink back to working condition without needing a full install.
  • What should I do if I see water under the sink? Turn off the water supply valves under the sink and dry out the cabinet to prevent further damage. Then schedule a repair visit so the source of the leak can be identified and fixed before the cabinet or flooring is affected.
