Black Mold Removal in Riverview, FL

My Riverview house is fairly new. How did black mold get in?

New construction doesn't stop water. Riverview grew from about 71,000 residents in 2010 to more than 107,000 in 2020, and Point2Homes data puts the median build year at 2006, with only about 7 percent of homes built before 1980. In homes that age, dark growth usually traces to a failed seal at a shower, a supply line behind a vanity, an attic air handler whose drain backed up, or windows and sliders that let in wind-driven rain. Slab construction means the bottom of the drywall is where water tends to sit. About 8 percent of homes are mobile homes, where roof seams and the underbelly are the usual weak points.

We flooded during Helene. Is the mold in our walls even if I can't see it?

Assume so if the house stayed wet. The Alafia River flows through northern Riverview, and Bay News 9 reported homes on Parkway Circle taking up to five feet of water during Hurricane Helene in 2024, higher than residents were used to. EPA's disaster guide says that if a flooded home couldn't be dried within 24 to 48 hours, you should assume mold is growing. Drywall, insulation and carpet that were under water generally come out, and the framing is cleaned and dried before anything is closed up.

Do I need to know what species it is before removal?

Usually not. EPA says that when mold is visible, sampling is generally unnecessary, and there are no federal limits to measure results against. A species name won't change the steps: fix the water, contain the space, remove what can't be cleaned, dry everything. Testing earns its cost when the source is hidden or when you want an assessor's clearance check after the work. In Florida that check comes from a separate company, since s. 468.8419 bars the remediator from assessing a structure it remediated within 12 months.

A note for Riverview owners and renters

Riverview is unincorporated, so rebuilding permits come from Hillsborough County Development Services. County storm guidance treats replacing drywall as cosmetic, but structural repairs in a Special Flood Hazard Area need a permit, and repairs reaching half the home's market value trigger substantial-damage rules. Roughly a quarter of occupied homes here are rented; tenants whose landlord hasn't fixed a leak can report it to Hillsborough County Code Enforcement.
