Spray Foam Insulation in Naples, FL

Spray Foam Insulation in Naples has to deal with a long cooling season and a housing stock that is older than many visitors expect. The city was settled in 1886, and American Community Survey estimates (via Point2Homes) put the median year built at 1983, with about 40% of homes dating from 1960 to 1979. Plenty of those houses still have their original attic insulation, or what is left of it after decades of AC service trips.

What the attic is up against

Naples Airport's 1991 to 2020 normals list average highs near 91 F in July and August and about 49.55 inches of rain a year, with the wet season running May through October. Heat builds under the roof all afternoon, and humid air rides in through every gap in the ceiling. When the air handler and ducts sit in that attic, a big share of what you pay to cool the house never reaches the rooms.

Storms and rebuilding

Wikipedia's summary of Hurricane Ian puts the damage to the city at an estimated $989 million, and much of the Naples area, including Pelican Bay and Bay Colony, lost power for several days. Many homes got new roofs afterward. A re-roof is a practical time to talk about foam on the underside of the deck, because the roof is new and dry and the attic is going to be disturbed anyway.

Condos, villas and part-year homes

At the 2020 census, 46.1% of the city's 18,225 housing units were vacant, which mostly reflects seasonal owners. A closed-up home still has to be kept cool and dry through the summer. Better attic insulation and air sealing make it easier for the AC to hold humidity down while you are away. For condos, we coordinate with the association on access, parking and work hours.

What a visit covers here

In a typical Naples ranch house we start at the attic hatch, usually in the garage or a hallway closet, and work out toward the eaves. We measure depth in several spots, look at how the air handler platform and duct trunks are laid out, and check the underside of the deck for stains left by past storms. If you have a tile roof, we note the underlayment age too, because that decides whether roofline foam should wait for a re-roof.

Flood rules

The city adopted new FEMA flood maps in 2024. Homes in AE, VE and AH zones follow floodplain rules, which can affect what can go below the base flood elevation. We keep insulation work to attics, roof decks and walls above that line unless your plans say otherwise. Call (239) 977-5375 or get a free estimate.
