Port Richey homes near the mouth of the Pithlachascotee took Helene's surge through the canals, and walls that stayed wet afterward are where dark mold tends to show up. Removing it means fixing the moisture, containing the room, cutting out colonized drywall and insulation, and drying everything before repairs. Call the number on this page to be connected with a local mold remediation company in Port Richey.

Signs to look for
- Black or dark green speckling low on walls in rooms that took canal water
- Dark rings on ceiling drywall below a roof patch or around a vent
- A sour smell from under a mobile home, often from wet underbelly insulation
- Cabinet backs under the sink that feel soft or show dark staining
- Bathroom ceiling spots that return soon after bleach
Color alone tells you little. EPA says it doesn't indicate how risky a mold is, so the question is how much there is and what it's growing on. Under about 10 square feet on a hard surface, a homeowner can usually handle it. Bigger patches belong with a remediation company.
What Port Richey homes are up against
During Helene in 2024, surge flooded homes on Bay Boulevard west of US 19; the road was still underwater the next afternoon and furniture floated inside living rooms. One resident said flooding got worse around 2 a.m. as water climbed through the canals. A Bay Boulevard family said it was the fourth major storm they had faced there.
The houses add risk of their own. About 44 percent were built before 1980 and about 15 percent are mobile homes, and roughly 36 percent of occupied homes are rented. Older plumbing and roofing, plus floors that sit over a crawl space with skirting around it, let dark mold grow for weeks before anyone sees it.

What drives the price
Angi reports most Tampa-area remediation jobs run $1,347 to $3,778, with many pros charging $10 to $25 per square foot. Its Tampa figures put a bathroom at $525 to $1,075 and a crawl space at $525 to $2,150. Those are regional ranges, not quotes. Your number depends on:
- How far the growth runs once the drywall is opened
- Whether the work is inside the living space or under a manufactured home
- Containment needed for more than one room
- Drywall and flooring replacement afterward
After you call
You'll be connected with an independent local remediation company. Expect questions about where the water came from, how long the area stayed wet and how large the stain looks. A site visit and a written scope follow. Florida law keeps the assessor and the remediator on the same house separate for 12 months, so any clearance check should come from a different business.
