The Southwest Florida attic problem

Most homes here put the air handler and every duct in a vented attic. In August that attic runs past 130 °F, and your cooled air travels through it. Toggle the two ways to deal with that.

Vented attic. Soffit vents let outside air in, the roof deck radiates heat down, and the attic settles somewhere north of 130 °F. Every foot of duct up there is a heat exchanger working against you, and the ceiling insulation is the only thing between that attic and your thermostat.

Sealed roof deck. Open-cell foam sprayed to the underside of the deck moves the thermal boundary to the roof. The attic becomes part of the house, the ducts sit in conditioned air, and the AC stops fighting the attic. This is the system most Naples and Fort Myers homes need.

Not every house qualifies. Vented attics with the ducts already inside, or with fouled insulation that has to come out first, get a different answer. That is what the assessment is for.

Which one is your attic? Request the assessment. We measure it on site and the written scope follows within 24 hours.

What we install, and when it is the right call

The condition of the building picks the system. Not the product with the best margin, and not whatever the last contractor quoted.

  • Spray foamOpen cell and closed cell

    Open cell at the roof deck brings a 130 °F attic and its ductwork inside the conditioned envelope. Closed cell only where the assembly needs a vapor retarder or rigidity: block walls, metal buildings, below-flood construction.

  • Insulation removalStorm, moisture, rodent damage

    Irma in 2017 and Ian in 2022 left attics across this coast that were never properly cleared. Wet or fouled material does not get foamed over. It comes out, and the attic gets looked at empty before anything new is priced.

    Insulation removal
  • Blown-inFiberglass or cellulose to depth

    Cheaper per square foot than foam and the right answer on plenty of houses. It only performs if the air sealing underneath was done first, so that is what gets checked before anyone quotes a depth.

  • Batt insulationFramed walls, garages, sound partitions

    Faced or unfaced fiberglass and Rockwool in framed assemblies. Straightforward work, priced on its own line, not folded into a foam quote.

  • Crawl spaceEncapsulation and floor systems

    Sealed liner and treated perimeter to keep ground moisture out of raised and coastal floor systems. Rare on slab construction, decisive on the homes that have one.

Open cell, closed cell, or neither

Two products that look the same coming out of the gun and behave nothing alike in the wall. Here is how we tell them apart, and when we skip foam entirely.

Open cell

Half-pound foam. Cells stay open, so it is soft, air-sealing, vapor-permeable and cheaper per board foot. The roof-deck system for Southwest Florida attics.

Density
½ lb / ft³
R-value
≈ R-3.7 per inch
Use it for
Roof decks, attics, sound

Closed cell

Two-pound foam. Cells close and hold gas, so it is rigid, a vapor retarder at thickness, and adds racking strength. Right product, narrow use case.

Density
2 lb / ft³
R-value
≈ R-6.5 per inch
Use it for
Block walls, metal buildings, flood zones
System selection by condition on site

Attic runs 130 °F+ and the ductwork is up thereOpen cell at the roof deckBrings the ducts inside the envelope instead of cooling the attic

Block wall, metal building or below-flood assemblyClosed cellVapor retarder and rigidity where they are actually needed
Ducts already inside, vented attic performingAir seal, then blown-in to depthCheaper and sufficient. Foam here is an upsell, not an upgrade
New construction, envelope specified on the plansBuilder scope to specScheduled against the trade calendar so it does not hold the build
Open cell is the right call for most Naples attics. Closed cell is the upsell other contractors push. We will tell you when foam is not the answer.

How a job runs

Four steps, in this order, every time. The measurements at the start are the same measurements at the end, and that is how you know the work was done.

  1. 01

    Assess & measure

    Attic temperature at the deck and at the floor. Where the ducts run. Existing depth measured with a staked ruler, not estimated. Moisture, rodent damage, air-leakage paths.

    On site
  2. 02

    Written scope

    The system, the thickness or depth, the square footage and the price, in writing, within 24 hours. No range, no "starting at".

    Within 24 hrs
  3. 03

    Install

    Floors, stairs and finishes masked before a single bag or hose moves. Where removal is scoped, it comes first and the attic is checked empty.

    Day of install
  4. 04

    Re-measure & sign off

    Depth checked against the same ruler. Deck coverage walked. You get the numbers, then the invoice.

    Same day

That blue stake is a depth ruler, set in the insulation before the hose runs. It is the only honest way to say how much material is on an attic floor. The ruler stays in the attic. It is there when we come back.

What the last 91 customers said

Every quote below is a real Google review, trimmed for length only. Read all 91 on Google.

“An employee came to give us a quote and gave us pictures of the attic to confirm why we were unable to keep the condo at a consistent temperature room to room. There were multiple areas of no insulation due to the last hurricane. The pictures after their work showed the attic floor entirely insulated, covered end to end with a foot of new insulation. We feel an amazing difference in the coolness of our condo, and have noticed that the air conditioner is no longer running non stop.”

Sandra C.Google review · condo attic, blown-in

“From first call to request pricing to completion of blown-in insulation in our 670 s.f. garage attic was less than 48 hrs. Time on-site to install baffles, blow in 16" of fiberglass insulation and clean up, less than 3 hrs.”

D. ClarkGoogle review · garage attic

“We've worked with Ideal Insulation for many years. They are always on time, professional, knowledgeable, and provide great pricing. This is rare in today's construction environment.”

Spec DevelopmentGoogle review · builder

“Ideal did my warehouse's insulation service with ease. They gave me a quote quickly and at the best price I found. They even expedited my open and closed cell insulation installation to meet my project deadline.”

Hailey B.Google review · warehouse, spray foam

“I asked for a quote and they did it virtually, beating the other quote I'd already received. They called me the next day to say they had availability in the next 24 hours. All new insulation in a 1960s Florida home with basically none. This feels like a truly family owned business that does really honest work.”
