Bathtub Leak Detection & Repair in Georgetown, TX

A leak that hides until you use the tub

Bathtub leaks are some of the most intermittent in the house. The tub sits dry and innocent all day, then leaks for the few minutes it is full or running, and stops again before anyone looks. That is why a tub leak so often shows up as a ceiling stain in the room below that appears after a bath and fades between them, with no obvious source upstairs.

Because the leak only happens under specific conditions, the way to find it is to recreate those conditions on purpose rather than wait and wonder.

The usual suspects on a tub

A few parts cause most tub leaks. The overflow gasket, behind the plate near the top of the tub, leaks when the water rises high enough to reach it. The drain shoe and its seal under the tub leak as the tub empties. The valve, spout, and diverter behind the wall can weep with the water on. And the caulk or grout where the tub meets the surround can fail and let water run down the outside of the tub, which looks like a leak but is really a seal problem.

Each of these leaks under a different condition, which is exactly what lets us tell them apart.

Filling, draining, and watching

We test a tub the way it actually leaks. We fill it to the overflow and watch for a leak that only appears at high water, which fingers the overflow gasket. We let it drain and watch the drain shoe below. We run the valve and diverter with the tub empty to isolate a behind-wall leak. Where there is access below, through a panel or the ceiling under the tub, we watch the underside directly during each step.

Recreating the leak on demand turns an intermittent mystery into a leak we can point at.

Repairing the source

A failed overflow gasket is replaced behind the plate. A leaking drain shoe gets a new seal, reset properly against the tub. A weeping valve or diverter is rebuilt or replaced behind the wall through a tidy access. Failed perimeter caulk is cut out and resealed so water stops running down the outside of the tub. The repair follows the part that the testing identified, not a guess.

We retest by filling and draining the tub after the fix, so the next bath does not bring the stain back.

Catching the drip before the ceiling does

An intermittent tub leak is easy to put off precisely because it is intermittent. But every bath feeds a little more water into the framing and the ceiling below, and in family homes around Wolf Ranch and Crystal Falls where the tubs see daily use, that adds up faster than you would expect.

If a ceiling stain shows up after baths, or you see water along the tub edge, that is the tub telling you which leak it has, and a short visit to test it is far cheaper than the ceiling and framing repairs an ignored tub leak eventually forces.
