Spray Foam Insulation in Sanibel, FL

Spray Foam Insulation in Sanibel is mostly repair and rebuild work. Sanibel is a sand barrier island at about sea level. Hurricane Ian made landfall just north of the island on September 28, 2022, partly collapsing the causeway and cutting road access, and homes across the island took surge and wind damage.

Low-rise, older housing

The only Sanibel buildings taller than two stories predate 1974, the year the city incorporated. Point2Homes' census summary shows about 73% of housing units date from the 1970s or 1980s, with a median build year of 1983. Many of those homes have been repaired or rebuilt since Ian, often elevated.

Elevated floors and attics

Elevated homes have floors over open air, which need insulation and sealing like a ceiling. Closed-cell foam under the floor insulates, seals and resists moisture. In the attic, roof leaks are the main threat in salt air, so we check the deck first.

Island logistics

Work on the island takes planning around access and schedules, and many owners are away part of the year. We can coordinate with you or a property manager.

Costs

HomeGuide lists closed-cell foam at $3.00 to $5.00 per square foot and roof deck foam at $1,500 to $9,000 nationally. The written estimate reflects access and is the price.

Building rules

Sanibel has its own rules for building on the island, including the low-rise rules that keep newer buildings to two stories and flood rules for rebuilt homes. Insulation is interior work, but if it is part of a rebuild or substantial repair, the permit covers it. Check with the city's building department before starting.
