Spray Foam Insulation in Havana, FL

Spray Foam Insulation in Havana works with a town whose buildings carry a lot of history. Havana was platted after the Georgia, Florida and Alabama Railroad was finished in 1902 and was incorporated on December 5, 1906, according to Wikipedia. On March 16, 1916, a fire destroyed 26 business buildings, leaving only two stores standing, so much of the town's commercial core was rebuilt after that. Today Havana is known for antiques, galleries and specialty shops. The 2020 census counted 877 housing units, with 9.7% vacant.

An older population, older homes

Wikipedia lists Havana's median age at 50.9, well above the national figure. Long-time owners often live in houses that have been updated piece by piece, with an addition here, a new roof there and new ductwork at some point. That leaves gaps in the attic where old and new framing meet and insulation that has been moved around by repairs. Sealing and topping up the attic is usually the first step. Floors over open crawl spaces come next.

Storefronts and commercial spaces

Older masonry storefronts on and near Main Street often have high ceilings and roofs with little insulation. Where there is an attic or a drop ceiling, air sealing and blown-in insulation can help. Where the roof deck is exposed, spray foam on the underside can insulate without lowering the ceiling, but it needs to be checked against how the building is used and any coating it would need. We talk through that before quoting.

Barns and outbuildings

Like the rest of Gadsden County, Havana grew up around shade tobacco, which Wikipedia says began in the county around 1829. Barns and outbuildings around town can be made usable as shops or storage with closed-cell foam on the roof and walls, once the roof is sound.

Elevation and climate

Havana sits at about 246 feet, on higher ground about 16 miles north of Tallahassee via US 27. Wikipedia's figures list a record high of 102F and a record low of 0F. Gadsden County is in IECC Climate Zone 2A, where the 2023 Florida energy code lists R-38 for ceilings.

Antique shops and stored goods

Shops and storage buildings that hold antiques, furniture or art suffer in humid heat. Wood swells, finishes cloud and paper goods mildew. Sealing the building envelope and insulating the roof keeps the inside steadier, which helps whatever cooling or dehumidifying you run work better. For a building like that, we talk about the target temperature and humidity before we pick the foam.

Costs

HomeGuide's 2026 national guide lists installed spray foam at $1.50 to $5.00 per square foot and job minimums of $1,000 to $2,000 or more. Smaller jobs in Havana, like a single attic section or one room's floor, can hit that minimum. Your written estimate is the price.
