Frequently Asked Questions

It depends on the space. Under a roof deck, open-cell spray foam is common because it seals and insulates at lower cost. On a vented attic floor, blown-in fiberglass over a sealed ceiling is often the best value. In walls that may see water, closed-cell foam resists moisture better than batts.

We use national figures: HomeGuide lists $1.50 to $5.00 per square foot installed, roof deck foam at $1,500 to $9,000 and an attic at $3,000 to $8,000. The written estimate after our visit is your price.

Spray foam is made by several chemical companies and sold as two-part systems that installers mix on site. What matters for you is that the product suits the space, meets code for its location (including any required ignition or thermal barrier), and is applied at the right thickness. We name the product type and thickness on the quote.

The Insulation Institute's summary of Florida's 2023 code lists R-38 for ceilings in Climate Zone 2. ENERGY STAR suggests R-49 for an uninsulated Zone 2 attic.

If it was soaked and is now matted, stained or musty, yes. Wet wall insulation usually came out with the drywall during repairs; attic insulation that got wet from roof leaks often needs to come out too.

It costs more than loose fill, is hard to remove, and needs the house empty for about a day while it cures. A sealed attic also changes how the AC handles humidity. Where those trade-offs do not pay off, we recommend something else.

Closed-cell foam resists water better than batts, so it is a common choice for lower walls in homes that have flooded. It does not stop flooding; it holds up better afterward.

Closed-cell adds some stiffness, but it is not a substitute for code-required roof attachment or storm protection, and we do not sell it as such.

HomeGuide advises at least 24 hours while foam cures.

It can. Have an HVAC contractor check the system when the attic becomes part of the conditioned space.

If what is there is dry and clean, adding on top works. If it is wet, soiled or blocking sealing work, remove it first.

Most sealing and blown-in jobs take a day.

In under-insulated, leaky attics, sealing and insulating usually reduce the cooling load. How much depends on the starting point and the system.

With association approval for shared spaces. We can look and explain options.

Lightly damp attic insulation from a small, quickly fixed leak sometimes can. Flood-soaked insulation should be replaced.

It depends on your policy and the cause. We provide photos and a written scope.

Repairs in Lee County's Special Flood Hazard Area require permits. Check with the county or your city.

The vacuum runs material straight into bags outside. We protect the path through the house.

Yes. It does not absorb water and settles little, which suits attics where leaks are a concern.

Most attics take a day or less including sealing.

No. Block homes are insulated on the inside face, behind the drywall.

HomeGuide lists blown-in attics at $900 to $3,600 nationally. Your written estimate is the price.

Closed-cell foam is a common choice because it resists water. The wall must be fully dry first.

Not practically. Block homes are insulated behind the drywall, so it is best done when walls are open.

It dampens sound between rooms well, though it is not full soundproofing.

Most remodel, addition and flood repair work does. Check with your building department.

Enough closed-cell to stop condensation is the minimum. A cooled building needs more. We write thickness and R-value on the quote.

Yes, with contents moved or covered. Overspray travels, so we plan the layout with you.

Closed-cell bonded to the underside of the steel keeps humid air off the metal, which is what causes the sweating.

It depends on the building and use. Check with your building department.
