Sink Leak Detection & Repair in Georgetown, TX

Four leaks, one cabinet

When a kitchen or bath sink leaks, the water collects in the cabinet underneath, which is both convenient and confusing. Convenient because the damage is contained. Confusing because four very different problems all end up as the same puddle on the cabinet floor: a supply line, the drain and trap, the faucet base above, or, in a kitchen, the garbage disposal connection.

Reading the cabinet is the first step. Water staining high on the back wall points up toward the faucet or supply. A puddle that appears only when you drain points to the trap. We let the pattern narrow it before we touch anything.

Telling the connections apart

Each connection leaks on its own schedule. The faucet supply lines and shutoffs are under constant pressure, so they weep steadily whether or not the water is running. The drain and P-trap only leak while water flows down. The faucet base leaks when the faucet is on and water runs down through the deck. The disposal leaks at its mounting or its drain connection when it is in use.

By running and stopping the water and watching where it appears, we usually identify the failed connection within a few minutes, no demolition required.

Why the cabinet floor matters

The state of the cabinet base tells us how long the leak has been working. A faint stain is recent. A swollen, lifting cabinet floor means the leak has run a while, common when a slow weep at a supply line goes unnoticed behind stored cleaning supplies. In Wood Ranch and San Gabriel Estates homes with original cabinetry, that base can be the first thing to give out.

We note the damage so you know whether the repair also needs a follow-up on the cabinet itself, rather than discovering it later.

Repairing the failed connection

A leaking supply line or shutoff gets replaced and properly seated. A weeping trap or slip joint gets fresh washers and correct alignment. A faucet base leak comes down to worn O-rings or a loose mounting. A disposal that leaks at the flange gets resealed, or at the drain elbow gets a new gasket. Each is a targeted fix once the source is known.

We test the repair by running and draining the sink and watching every joint, so the cabinet stays dry for good rather than until the next time you fill the basin.

A small leak that quietly does damage

Sink leaks rarely flood. They seep, and that slow, hidden water is what warps cabinets, lifts countertops at the seams, and grows mold in a closed cabinet. The repair is almost always minor. The damage from ignoring it is what gets expensive.

If the cabinet under a sink smells damp, feels soft, or shows a stain, that is reason enough to have the connections checked. We would rather reseat a slip joint or swap a supply line today than rebuild a vanity base for you next season, and the difference between the two is usually just how early the leak gets found. A two-minute check of the cabinet now is the cheapest insurance against a swollen base later.
