Why mold is common in Largo
The St. Pete–Clearwater airport, a few miles east of Largo, records about 53.6 inches of rain in an average year, with July the wettest month. Lying between the Intracoastal Waterway and Tampa Bay, Largo stays humid through the summer.
In the fall of 2024, central Pinellas took Helene's surge along the coast and Milton's heavy rain two weeks later. For inland Largo streets the rain was the bigger test: roofs, gutters and yard drainage that could not keep up let water in through ceilings, windows and slab edges. Materials that stayed wet behind quick repairs can still be growing mold.
Largo has a large share of older homes and many manufactured-home and 55-plus communities. In manufactured homes, moisture can collect under the floor behind the skirting, and older site-built homes often have aging roofs, windows and plumbing.

Largo inspection prices use the Tampa Bay range of $225 to $646 that Brandon-area homeowners reported. Remediation figures are drawn from Florida contractor price guides from 2025–2026. Work under a manufactured home, such as replacing a vapor barrier or a damaged subfloor, is priced differently from wall work in a site-built house, so get the scope in writing. See the remediation cost guide.
Florida mold licensing: what to check
Before a contractor crawls under your Largo home or opens a wall, ask for two things: a Florida DBPR mold license and a certificate of the $1 million liability coverage state law requires. The license is required for jobs larger than about 10 square feet, and Pinellas County has 179 licensed assessors and remediators to choose from.
Look the number up at myfloridalicense.com. Plan on separate companies for the assessment and the cleanup, because Florida generally prevents an assessor from remediating the same home within 12 months.
Will insurance cover it?
Manufactured homes are where Largo insurance questions get tricky. Many are insured under separate manufactured-home policies with their own rules about water damage and mold, and flood coverage for them is a separate purchase. Check the declarations page for a mold sublimit or exclusion before anything goes wrong.
For site-built homes, a sudden pipe burst or storm damage to the roof may be covered, usually up to a mold limit that is often $10,000, while mold from ongoing humidity under a floor or behind a leaky window is usually excluded as maintenance. Water rising from outside is a flood loss. Florida requires notice of a new claim within 1 year. See does insurance cover mold.
