Our shower grout kept growing mold no matter how often we scrubbed it. Turned out our exhaust fan was barely pulling any air at all. They fixed the tile and were upfront that the fan needed attention too.

No more allergy symptoms since they cleaned the mold from our HVAC and bedroom walls.

We check whether the exhaust fan is properly sized and actually venting outside, not just running.
Remove
Mold in grout, caulk, and any affected drywall or subfloor is removed or treated as appropriate.

Local knowledge
Bathroom Mold Remediation for St. Louis, MO homes
Bathroom Mold Remediation in St. Louis tends to start the same way mold does across City of Saint Louis: plumbing leaks and poor ventilation that let damp air linger and mold spread. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from Hillsdale, University City, Pine Lawn and the rest of St. Louis call us.
We handle bathroom mold remediation for St. Louis the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.

Good to know
Bathroom Mold Remediation in St. Louis, MO: common questions
Can I clean bathroom mold myself?
Light surface mold on tile or grout can often be managed with regular cleaning. If it keeps returning quickly or has spread to drywall, that usually points to a moisture or ventilation issue worth having checked.
Is it my exhaust fan or a plumbing leak?
Mold concentrated around the shower and ceiling usually points to ventilation. Mold near the base of the toilet, under the vanity, or along the floor is more likely a slow leak, which we'll check for separately.
How long should I run my bathroom fan after a shower?
A common guideline is 20 to 30 minutes after showering to fully clear humid air. If your fan can't keep up with that even when it's working properly, it may be undersized for the room.
Do I need to leave my St. Louis home during the work?
Usually no. We seal the work area under negative air, so most of the St. Louis home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Why does my bathroom mold keep coming back?
Recurring mold almost always points to insufficient ventilation, either a fan that's too small, not vented properly, or not run long enough after showers. We check this as part of every job.
Will you remove and replace my grout?
We can remove and treat affected grout and caulk as part of the job. Full re-tiling is outside our scope, but we'll let you know if that's what the situation calls for.
Is the bathroom mold remediation you do in St. Louis to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across City of Saint Louis.
Do you serve St. Louis?
Yes. We cover all of St. Louis, including Hillsdale, University City, Pine Lawn, and the rest of the St. Louis area. We are based in Valley Park, about 30 minutes from our Valley Park base, and answer our own phone around the clock.
