Leaking Toilet and Tub
Fixing leaking toilets and tubs and drying out the damage they leave behind.
Bathroom leaks are deceptively common causes of serious water damage because they happen right above finished flooring and, in two-story homes, right above a ceiling. A slow leak at the base of a toilet or around a tub can run for weeks before it’s noticed, soaking subfloor and, eventually, showing up as a stain on the ceiling below. Across the older housing stock in Commerce and Homer, the newer construction around Braselton and Hoschton, and the busy rental market in Gainesville, we see this pattern constantly: a bathroom leak nobody caught until it became a ceiling problem in the room underneath. MitigAid Restoration repairs the fixture and handles the resulting structural drying and repair as one job.

Common Sources of Toilet Leaks
A leaking toilet is usually one of a few things: a worn wax ring seal at the base that no longer keeps water from seeping under the toilet with every flush, a cracked tank or bowl, a failing supply line connection, or a faulty fill valve that keeps running and eventually overflows. A wax ring leak is especially deceptive because the water runs down under the toilet base and into the subfloor rather than pooling visibly on top of the floor, so it’s often not caught until the surrounding flooring has already been damaged.
A rocking or unstable toilet is often the first physical sign of a failed wax ring seal, since a compromised seal also means the toilet is no longer sitting flush and solid on the flange.
Common Sources of Tub and Shower Leaks
Tub and shower leaks typically come from failed caulking or grout that lets water behind tile and into the wall cavity, a cracked or improperly sealed drain fitting, a failed overflow gasket, or aging supply line connections behind the wall. Because these leaks are often behind a wall or under a tub, they’re rarely visible directly - the first sign is usually a stain on an adjacent wall or ceiling, or a soft spot in flooring near the tub.
In upstairs bathrooms, which are standard in the two-story homes common throughout newer Braselton and Hoschton subdivisions, a tub or shower leak frequently shows up first as a stain on the downstairs ceiling rather than anywhere in the bathroom itself.
Why These Leaks Go Unnoticed
Bathroom fixtures are used daily, which means small amounts of water are already expected around a tub or toilet - splashes, condensation, a wet bath mat - so early stages of a real leak often blend into normal bathroom moisture. Add in that the leak point is frequently hidden under the fixture or inside a wall, and it’s easy to see why these leaks tend to be caught late rather than early.
This is a particularly common issue in Gainesville-area rentals, where fixtures see heavy daily use, maintenance reporting can lag, and turnover between tenants sometimes means a slow leak goes unreported for an entire lease term.
Diagnosing the Leak
For toilets, we check the wax ring seal, the base connection to the flange, the supply line fitting, and the tank-to-bowl seal. For tubs and showers, we inspect the caulk and grout lines, the drain assembly, the overflow plate, and, where accessible, the supply and drain plumbing behind the wall. We also check the subfloor and surrounding flooring for softness or staining that indicates how long the leak has actually been running.
If the leak isn’t obvious from a visual inspection, we use moisture meters to trace where water has spread, since a leak’s actual source and the location of the visible damage aren’t always the same spot.
Toilet Repair Process
A wax ring failure requires pulling the toilet, removing the old wax ring, inspecting the flange for damage or corrosion, and resetting the toilet with a new seal. If the flange itself is damaged - which is common once a leak has been running long enough to rot the subfloor underneath it - the flange and the affected subfloor section need to be repaired before the toilet is reset. We also replace worn supply lines and fill valves as part of the same repair when needed.
Once reset, we check that the toilet sits flush and stable, confirming the new seal is holding before considering the repair complete.
Tub and Shower Repair Process
For tile surrounds, we remove and replace failed grout and caulk, since gaps in either allow water directly into the wall cavity behind the tile. If the leak is coming from the drain assembly or overflow, we replace the gasket or fitting and pressure test before closing anything back up. Where the leak has already reached the wall cavity, we open the wall as needed to dry and repair the framing and drywall behind it.
For leaks traced to supply lines inside the wall, we make the repair at the source rather than just resealing the visible surface, since resealing over an active internal leak only delays the same problem.
Repairing the Resulting Water Damage
Once the fixture is repaired, we address whatever the leak affected - typically subfloor around a toilet or tub, and often a ceiling in the room below if the leak has been running for a while. Damaged subfloor gets cut out and replaced rather than left in place, since compromised subfloor won’t properly support new flooring or fixtures. Ceiling damage below the bathroom gets repaired the same way we handle any other water-damaged ceiling: cut back to sound material, dried, and rebuilt to match.
We test moisture levels before closing up any repaired area to confirm the structure has actually dried, not just that the visible leak has stopped.
Insurance Considerations
Sudden bathroom leaks are commonly covered under homeowners insurance, though slow leaks that have clearly been running for an extended period before discovery can sometimes raise questions about maintenance, which is part of why we document the condition of the fixture, the cause of the failure, and the extent of the damage carefully. We coordinate directly with your adjuster to make sure the claim reflects the actual scope of work.
We provide a free estimate for both the fixture repair and any resulting structural work, so you know what’s involved before repairs start.
When to Call Us
If a toilet rocks when you sit on it, if caulk around a tub is cracked or missing, or if you notice a stain on a ceiling below a bathroom, it’s worth having it checked before the damage spreads further. These leaks rarely get better on their own, and the subfloor or ceiling damage only grows the longer the source goes unaddressed.
