Buying in Florida? What to Ask About the Chimney and Vents

On a Florida house the chimney is rarely the biggest venting risk in the building. The dryer duct usually is, and neither appears properly on a standard inspection.

Short answer

Ask four things: whether the structure is masonry or a framed chase, whether the chimney flashing was redone during any post-storm roof replacement, whether the stucco sounds hollow anywhere, and when the dryer vent — and in a condo, the shared riser — was last cleaned. A general home inspection does not cover any of them to a useful standard.

The four questions

None of them takes long to answer and all four have real money attached.

Masonry or chase?

It decides every subsequent answer. Masonry means crowns, flue tiles and possible relining. A framed chase means a chase cover, a metal flue system and a factory-built firebox with a model number and a parts list that may or may not still be supported.

Was the flashing redone in a reroof?

Florida roofs get replaced fast after storms and the chimney detail is the one that gets rushed. Mastic smeared across the joint instead of stepped metal let into a reglet will leak within a season or two. Photograph it; it is visible from the ground.

Does the stucco sound hollow?

Tap the accessible faces. Hollow means water has been behind the render long enough to break the bond, and on a framed chase it may mean rot behind it. This is a minute's work and it is not on any standard checklist.

When was the dryer vent last cleaned?

In a house, the run is probably long and routed through the attic. In a condominium there is also a shared vertical riser the whole stack discharges into, which the association maintains — and frequently nobody can say when it was last done.

What the seller's answers tell you

Two of these are red flags less because of the answer than because of the hesitation.

Nobody knowing whether the chimney vents anything is common and benign — plenty of Florida chimneys are decorative. Nobody knowing whether the condo riser has ever been cleaned is a maintenance gap in the common elements, and it is worth asking the board rather than the seller.

A gas fireplace with no service history is close to universal and is not a deal point. It is a service visit rather than a negotiation.

Get it in the inspection period

A Level 2 chimney inspection takes an hour or two. A dryer vent assessment takes less. Both are cheap relative to what they can find.

What comes back most often

Four findings, in rough order of frequency on Florida housing.

A corroded chase cover, close to universal on anything over about fifteen years old. Flashing bedded in mastic after a storm reroof. A lint-packed dryer run on a long attic route. And a gas appliance that has never been serviced, with a degraded glass gasket or a corroded exterior terminal.

None of those is dramatic on its own. Together they are a realistic picture of what a Florida house needs, and it is a considerably more useful list than a chimney sweep report on a fireplace nobody has ever lit.

Frequently asked questions

Will the general home inspector cover this?

Superficially. No camera in the flue, no tap test on the stucco, and dryer vents are typically noted as present rather than assessed.

Is it worth it if there is no fireplace at all?

The dryer vent assessment is, absolutely — it is the venting risk in most Florida houses. The chimney part obviously is not.

Who pays for the riser cleaning in a condo?

The association, as a common element, under most declarations. Worth confirming before closing rather than after.
