In Seffner, attic mold usually traces to a roof leak, an air handler or drain line in the attic, or an exhaust duct releasing humid air under the roof. Removal means fixing the moisture, bagging insulation that got wet and cleaning or replacing the affected decking. Call the number on this page to be connected with a local mold remediation company in Seffner.

Where is the moisture in my attic coming from?
Seffner sits about 13 miles east of downtown Tampa, between Interstate 4 and Dr. Martin Luther King Jr. Boulevard, where new subdivisions are replacing live oaks, strawberry farms and lakeside land. Away from the coast, attic moisture comes from three places: the roof, the air conditioning, and the house itself. Shingles, flashing and vent boots take a beating in summer thunderstorms. An air handler in the attic produces condensate every hour it runs, and a clogged line or cracked pan sends that water into insulation. Showers and dryers add steam that should leave through ducts to the outside, but sometimes ends up in the attic. Trees over older homes add one more risk: limbs that gouge the roof or clog gutters.
Does the roof have to come off?
Not usually. Mold on sound plywood is cleaned, typically by HEPA vacuuming, scrubbing or media blasting, then dried. Only decking that's soft, delaminated or rotted gets replaced, and that is roofer's work. Insulation is different: once it's wet or moldy it generally comes out, because it is porous. Angi reports attic mold remediation in the Tampa area typically runs $1,075 to $4,300; how much decking and insulation is involved sets the number.
I rent. Who do I call if the landlord won't fix the leak?
Start with a written request to the landlord and dated photos of the stain or growth. Seffner is unincorporated, so if the leak isn't addressed, Hillsborough County Code Enforcement handles housing-standards complaints, and its report page lists mold, A/C and heating among them. Reports go through an online form, and anonymous complaints aren't accepted.

A note for Seffner homeowners
If removal uncovers rotted decking or framing, the structural repair runs through Hillsborough County Development Services, which handles permits for unincorporated areas. Florida's s. 468.8419 means any clearance check after the work comes from a separate mold assessor. You can confirm the license of the remediation company or the assessor on DBPR's online licensee search before anyone climbs into the attic. When you call, you'll be connected with an independent company that covers east Hillsborough; expect a site visit and a written scope before work begins, and ask how the attic hatch will be sealed while insulation is bagged and carried out.
