Spray Foam Insulation in Monticello, FL

Spray Foam Insulation in Monticello starts with a striking fact: Wikipedia lists Florida's highest recorded temperature, 109F, as set in Monticello on June 29, 1931. Even ordinary summers here are long and hot, and older homes feel it most. Monticello was settled in 1827, incorporated in 1859 and named after Thomas Jefferson's estate. It is the only city in Jefferson County and the county seat, about 25 to 26 miles east of Tallahassee by I-10 or US 90.

Older homes and many vacancies

The 2020 census counted 1,323 housing units in Monticello, with 15.8% vacant and a homeowner vacancy rate of 4.6%, according to Wikipedia. The median household income was $43,780. That points to an older housing stock with some homes between owners or waiting for repairs. Before a vacant or long-held house is back in use, it is a good time to remove damaged insulation, seal the attic and fix the floor.

Historic buildings

Monticello's landmarks include the Perkins Opera House, a 19th-century mercantile building turned theater, and the Old Howard Academy, built in 1936 and added to the National Register in 2021. Older houses around town often have high ceilings, chimneys, and floors over open crawl spaces. In those houses we seal the attic around chimneys with fire-rated material, blow in insulation to depth, and handle the floor with closed-cell foam or an encapsulated crawl space, depending on what the foundation allows.

Farms and outbuildings

Jefferson County is largely rural, and many properties have barns, equipment sheds or metal buildings. Closed-cell spray foam on a steel roof stops condensation and cuts the heat that builds up under the panels, which matters in the place that holds the state's heat record.

Code and targets

Jefferson County is in IECC Climate Zone 2A. The 2023 Florida energy code lists R-38 for ceilings in Zone 2. DOE suggests R-49 to R-60 for an attic with no insulation and R-13 for an uninsulated floor.

Vacant and inherited homes

With about one in six housing units vacant in 2020, Monticello has its share of houses waiting for a new owner or a family decision. Before such a house is lived in again, check the attic and the crawl space. Insulation that has been home to rodents or soaked by an old roof leak should come out. Once it is gone, sealing the attic floor and insulating to the right depth makes the house much easier to cool.

Cost guidance

HomeAdvisor's June 2026 figures put a typical insulation removal job at $600 to $1,200, and HomeGuide's 2026 guide puts attic air sealing at $350 to $3,000. Your price depends on how much material, how much damage and how hard the space is to reach.

Check your utility

Rebates depend on who supplies your power. If your electricity comes from Duke Energy Florida, its attic insulation program requires a free Home Energy Check first, existing attic insulation of R-19 or less, and a Duke-prequalified contractor.
