Look before you clean
Photograph the mold, the air-handler closet, ceilings and under sinks. Note the AC setting you left.
Tell the association in writing
If the water may have come from a roof, an exterior wall or a neighbor's unit, the association may need to be involved.
Check your policy
Many Florida homeowners policies limit mold coverage, often to $10,000. Check your declarations page before signing a contract.

Longboat Key housing and storms
Census 2020, Census Bureau 2025 estimate and American Community Survey 2020–2024.

Condos and the two-company rule
In a Florida condo, the association maintains common elements (s. 718.113(1)), and owners insure their unit finishes, cabinets and appliances (s. 718.111(11)(f), (g)). Read your declaration and talk to your manager in writing. The condo mold page has more.
If an association or an owner wants testing, keep it separate: in Florida, a company that does the mold assessment generally can't also do the remediation on the same structure within 12 months, and vice versa (s. 468.8419).
Florida licenses mold assessors and mold remediators through the Department of Business and Professional Regulation (DBPR) under Chapter 468, Part XVI. Before you hire, look up the company's license at myfloridalicense.com (search by name or license number). Some contractors are exempt; ask which license covers the work.
Mold cleanup itself usually isn't permitted work, but rebuilding often is. Check with the town building department; your rebuild contractor should confirm and pull any permit.
Published national estimates, not quotes: HVAC and duct work runs $3,000 to $10,000 and a typical job $1,200 to $3,750 (Fixr, Aug 2025; This Old House with Angi data, Mar 2026). Sarasota-area quotes vary. See the cost guide.
Longboat Key mold questions
Which county is my Longboat Key home in, and does it matter for mold?
Longboat Key is almost equally divided between Manatee and Sarasota counties, but it is one town with its own government. For rebuild permits, check with the Town of Longboat Key building department. The mold license rules are statewide, so the DBPR check at myfloridalicense.com is the same on either end of the island.
Does my condo association have to pay for mold in my Longboat Key unit?
Sometimes. The association maintains common elements (s. 718.113(1)) and generally repairs damage from an insurable event unless an owner's negligence caused it (s. 718.111(11)(j)). Unit finishes such as wall coverings, cabinets and appliances are usually the owner's to insure. Read your declaration and talk to your manager in writing. Not legal advice.
Can I get quotes while I'm away from Longboat Key?
Yes. Describe your situation any time and say you are out of town; companies reply on their own schedules and can arrange access through you, a neighbor or your building manager. Ask for photos of what they find and a written remediation plan before you approve work. Look up the company's license at myfloridalicense.com first.
