What it usually means

Exterior wood rot in Florida comes from rain and humidity finding unsealed wood — trim, fascia, siding, posts — caught early a handyman can replace sections before it spreads into structure.

Handle it soon — these get more expensive with time.

Common causes:

• Rain and humidity soaking unsealed exterior wood

• A leak, gutter overflow, or splashback keeping wood wet

• Paint or sealant that failed and let moisture in

• Insect damage compounding the rot

Red flags when hiring

• Painting over soft, rotted wood instead of replacing it

• Replacing rotted wood without fixing the water source

• Rot that has reached structural framing or posts

• No proof of insurance or a track record — Florida doesn't license this trade, so those are what protect you

Quick answers

Why is exterior wood rotting on my Florida home?

Florida's rain and humidity are relentless on wood, and anywhere the paint or seal has failed, water gets in and rot follows — trim, fascia, siding, railings, and posts are common spots. A leak or overflowing gutter accelerates it. Replacing the rotted wood and keeping it sealed and painted is what holds it off.

When is wood rot more than a handyman job?

When it reaches structure. Replacing rotted trim, fascia, siding boards, and non-structural posts is standard handyman work. But if the rot has spread into load-bearing framing, support posts, or the roof structure, that's a job for the appropriate licensed trade, since it affects how the home holds up.

What this usually costs in Florida

Typical small repair visit: $100–$500 (typical ~$275)

A few hours of minor, non-structural work. A handyman handles minor repairs; licensed trades (electrical, plumbing, HVAC, roofing, structural) are separate.

Licensing & permits in Florida

Florida does NOT issue a state license for this trade (local licensing was preempted for most non-structural trades). What protects you instead: general-liability insurance, workers’ comp, and a real track record — exactly what our verification checks.

Whether a permit applies depends on scope — when in doubt, ask the county building department before work starts.

Basis: HB 735 (2021) local-license preemption.
