Caulk that won't stay clean, soft floors, stained ceilings
If black spots keep returning on the shower caulk, or the floor by the toilet has gone soft, the mold is probably being fed by water you can't see. Call +1-844-326-4757 to reach an independent, licensed and insured bathroom mold contractor in Pinch who finds the water source before opening up tile or drywall.
This line is free: ESS Mold Inspection only routes calls, and independent local contractors do all of the work.
Bathroom mold, explained
Bathroom calls split into two groups. Some of it is surface growth on grout lines and caulk, feeding on body oils and soap scum, and a good cleaning handles it. The harder cases are growing out of sight, in the wall behind the tub surround or in the subfloor, kept damp by a cracked shower pan liner, a dripping valve body or a toilet seal that's been seeping for a long time.
People fight caulk mold for years without winning. Once mold roots into the silicone itself, bleach only lightens the color for a few weeks, so the bead has to be cut out, the joint dried and cleaned, and fresh mildew-resistant silicone laid in. Ceilings are the other hot spot: steam from long showers condenses on cold drywall above the tub when the exhaust fan is undersized, isn't run long enough, or vents into the attic instead of outdoors.
Older tub surrounds often hide paper-faced drywall behind the tile, and paper is mold food once water gets past the grout. When the cause is a leak, the remediator and a plumber usually have to coordinate.
Why homeowners call
You'll be asked about the location of the mold, any soft flooring or loose tile, and stains downstairs before the call is routed.
Remediators in the network are independent local companies carrying their own license and insurance coverage, which you're encouraged to verify. Some states keep assessment and remediation with separate companies, and the local pro works within that.
A ceiling stain that's growing or a floor that's flexing gets prioritized, and plenty of callers see someone that day.
Nothing gets opened up until you have a written quote that spells out the demo area, the mold work and what's needed to rebuild.
Expect a moisture meter that reads behind tile, an infrared camera, a borescope for peeking into the wall through a small hole, oscillating cutters and HEPA containment.
Scope of work
Bathroom jobs range from a caulk replacement to a full shower teardown, and most land somewhere between.
Surface growth on grout is cleaned and the grout sealed, while moldy silicone is cut out completely, the joint dried overnight, and new mildew-resistant caulk applied.
When readings behind the tile run high, a section is opened inside plastic containment, the moldy drywall and backer are removed, and the studs are HEPA vacuumed and cleaned. The wall goes back with cement board and a waterproof membrane instead of drywall.
A failed wax ring lets water wick into the subfloor for months before the floor feels spongy or tiles around the toilet loosen. The toilet is pulled, the rotted subfloor cut out, framing dried and treated, and new plywood installed.
A P-trap or supply line that drips a little each day ruins the cabinet floor and the wall behind it. The cabinet often has to come out so the wall and floor behind it can be checked.
Ceiling mold from steam is cleaned or the drywall replaced depending on depth, and then the fan gets fixed. A common rule of thumb is about 1 CFM per square foot of floor with a 50 CFM minimum for small baths, ducted outdoors and run about 20 minutes after each shower, often on a timer switch.

The process
Finding the water comes first in every step.
Describe the spots, any soft flooring, and whether there's an upstairs bath above a stain. The line then connects you with an independent contractor in Pinch.
For a live leak, the pro often comes the same day, carrying a meter, a thermal camera and drop cloths for the floor.
The contractor scans the tile, floor and ceiling for moisture, check the fan's airflow and where it vents, and may use a borescope through a small hole. Any plumbing repair needed is flagged in the written quote so it can be scheduled first.
Request photos of the open cavity, readings taken before rebuild, and whatever workmanship terms the contractor puts on paper. Keep it with your plumbing repair receipt.
From the dispatch log
Each of these started as a small stain and turned out to be a water problem.
After months of spraying cleaner on the shower caulk, a caller was fed up with black dots coming right back. The independent pro saw growth inside the bead itself and an exhaust fan pulling almost nothing. The wall behind the tile read dry.
Outcome: Old silicone cut out and replaced, grout sealed, and the fan upgraded with a 20-minute timer.
A caller noticed the floor flexing next to the toilet and two tiles that had cracked loose. Once the toilet came up, the wax seal was crushed and the subfloor around the flange was rotted and moldy. Luckily the framing underneath was still sound.
Outcome: Subfloor section replaced, joist treated, new flange and wax ring set, then tile repaired.
A landlord called after a tenant reported a gray patch spreading on the ceiling above the tub. The remediator found an undersized fan whose duct stopped in the attic. One corner of the drywall had softened.
Outcome: Damaged ceiling section replaced, new fan sized to the room and vented to an exterior roof cap.
A family saw a brown ring and fuzzy growth on the dining room ceiling, directly under the second-floor shower. Thermal imaging and a meter pointed to a failed shower pan liner leaking into the floor system. The pan needed a plumber and a tile setter.
Outcome: Ceiling below opened and cleaned in containment, joists dried, and the shower pan rebuilt before closing up.
These are composite examples based on common calls to the line, not individual customer reviews.
Before you call
Say where the spots are and the dispatcher will match you with a bathroom specialist working in Pinch.
Call +1-844-326-4757Silicone is porous enough for mold to grow into it, so surface cleaners only hide it for a while. The fix is to cut the caulk out, dry and clean the joint, and apply fresh mildew-resistant silicone. Better ventilation keeps the new bead clean longer.
Warning signs include loose or hollow-sounding tiles, cracked grout that keeps reappearing, a musty smell that won't clear, and stains on the other side of the wall. An independent pro in Pinch can confirm it with a moisture meter, thermal camera or borescope without tearing the shower out.
If the growth is only on the paint and the drywall is firm, cleaning and repainting is often enough. Sagging, soft or deeply stained drywall needs replacement. Either way, the fan has to be fixed or it'll come back.
A common rule of thumb is about 1 CFM per square foot of floor area, with 50 CFM as the minimum for small bathrooms. The duct has to exhaust outdoors, and long, kinked runs reduce what the fan actually moves. A timer switch set for roughly 20 minutes works well.
Often only part of the wall comes off, if the readings show the water stayed in one spot. A leaking pan generally means the shower floor and bottom tile courses get rebuilt. You'll see the demo area in the quote before work begins.
Often it's both. A leaking shower valve, supply line, drain, wax ring or P-trap creates the moisture, and mold is the result. If a leak is found, expect to coordinate a plumber and the remediator so repairs happen in the right order. Ceiling mold from steam alone usually needs no plumber.
