Bathroom Mold Remediation

More Than Surface Mold on the Grout

A little mildew on caulk and grout is a cleaning issue. Mold that keeps coming back on the ceiling, spreads across the wall behind the shower or shows up under the vanity is a sign of a bigger moisture problem: a leaking shower valve, a failed tub surround, a toilet wax ring that seeps or an exhaust fan that does not actually move air outside.

We remediate bathroom mold under containment so the rest of the house is protected, remove damaged drywall and backer board, clean the framing and help you correct the cause. That way your new tile and paint go onto a dry, clean structure.

Minimum exhaust

Ventilation Makes or Breaks a Bathroom

Building codes require bathroom exhaust fans to move at least 50 cubic feet per minute and vent to the outdoors. Many older New Jersey homes have fans that are undersized, clogged with lint or ducted into the attic. Fixing that is part of every bathroom project we do.

What Our Bathroom Mold Remediation Includes

Shower Wall Remediation

Leaking surrounds and tile walls are opened, wet backer board removed and the cavity cleaned.

Ceiling Mold Removal

Stained or moldy ceiling drywall is removed or cleaned depending on how deep the growth goes.

Vanity & Toilet Areas

Subfloor and wall areas under vanities and around toilets are checked and remediated.

Exhaust Fan Fixes

We verify fan airflow and correct ducting that ends in the attic or soffit.

Leak Identification

Moisture meters and thermal imaging locate hidden plumbing and shower pan leaks.

Containment

Bathrooms are sealed with poly and run under negative air so spores stay out of bedrooms.

When to Call a Professional

  • Mold returns within weeks after cleaning with bleach or bathroom cleaner
  • The visible area is larger than about 10 square feet
  • Drywall is soft, bubbling or stained below a shower or tub
  • There is a musty smell in a closet or bedroom next to the bathroom
  • The ceiling below an upstairs bathroom has water stains

Our Bathroom Remediation Process

We inspect with a moisture meter and thermal camera to find the extent of the damage, then build containment at the bathroom door and run HEPA air filtration. Damaged ceiling, wall board and insulation are removed, the framing is cleaned and treated, and we confirm the area is dry. If the cause is a plumbing leak or fan problem, we fix it or coordinate with your plumber before the room is closed up.

Small ceiling jobs can be completed in a single day. Shower wall projects that require opening tile usually take two to three days before the bathroom is ready for rebuild.

Bathroom Mold Remediation FAQ

Can I remove bathroom mold myself?
Small areas of surface mildew on tile and caulk, under about 10 square feet, can usually be cleaned by a homeowner. Larger areas, recurring growth or mold on drywall should be handled professionally.
Why does mold keep coming back on my bathroom ceiling?
Recurring ceiling mold is almost always caused by poor ventilation. Steam condenses on the cool ceiling and the fan does not remove it fast enough. Upgrading the fan and running it 20 minutes after showers usually solves it.
Do you rebuild the bathroom after remediation?
We handle remediation and can coordinate rebuild with a trusted local contractor, or you can use your own.
Is black mold in the shower dangerous?
Most dark mold in showers is a common species, not Stachybotrys. Any visible growth should still be cleaned, and growth behind the walls should be remediated.
