Request an estimateIs closed-cell foam worth the extra cost in Tallahassee?
Closed-cell foam insulation is a dense spray foam that slows heat, stops air leaks and blocks moisture in one layer. In Tallahassee we use it mostly in walls and under roof decks, where humid air is the problem.
Most folks who call about closed-cell foam have already read up on spray foam insulation, and what they're living with is an upstairs that won't cool down or a power bill that keeps climbing. The price turns on how much area you want covered and how thick, whether the walls are open framing or finished drywall, and how easy the attic is to move around in. The schedule turns on whether a roof leak needs fixing before we spray, and on when your family can be out of the house for the work. You'll get your own number after I've seen the space and walked you through what I found.
How we put in closed-cell foam
Closed cell costs more, so I'll tell you where it earns its keep and where it doesn't. It pays off in walls that need to hold back humid air and in attics where the ductwork lives, but in a plain attic with nothing up there, sealing the gaps and topping up the loose fill usually does as much for less. Before we spray, I look at how the whole wall or roof is built, because closed-cell foam already blocks moisture, and a plastic vapor barrier on the inside would give water a place to get trapped. Any roof leak gets fixed first, since foam over wet wood just hides the rot. Then our crew covers what can't be moved, sprays the foam in passes to the thickness we agreed on, trims it back and cleans up.
Where the foam doesn't need to stop moisture, open-cell foam insulation is often the better buy, and I'll say so. Property managers call us for commercial insulation when a building needs the job planned out around the people using it.
Permits and humid air on closed-cell foam jobs in Tallahassee
Inside the city limits, the city's Building Inspection Division issues the permits needed to build, renovate or expand a house. Whether your foam job needs one isn't something I'll guess at, so we find out whether your address is inside the city limits or out, check with the office that covers it and handle the paperwork when the job needs a permit. If you'd rather ask yourself, the division takes permit questions at 850-891-7001, option 2 and then option 1.
Summers here are long and muggy, so a lot of our calls are rooms over the garage that never cool off and attics where the ducts bake all afternoon. Plenty of houses also have older insulation that's settled flat or soaked up a past roof leak, and that comes out before any foam goes in. We see the same hot attics on jobs in Bradfordville and Crawfordville, and we work in other cities around Tallahassee too, so call and ask if yours isn't listed.

Frequently asked questions
What is the best way to choose between closed-cell and open-cell foam in Tallahassee?
Start with where the foam is going, because federal building guidance rates closed-cell as the preferred spray foam for walls in hot, humid climates like ours. Closed-cell does about twice the insulating work per inch, which is one reason it costs more, while open-cell is much better at keeping sound down. So you're weighing a cooler house and lower bills against quieter rooms and price, and I'll show you where each one makes sense in your house.
How much does closed-cell spray foam cost in Tallahassee?
Closed-cell spray foam in Tallahassee usually runs about $1 to $1.50 per board foot, which is one square foot of foam one inch thick. That's the going rate in the area, not our quote, and your number depends on how many square feet you're covering and how thick it goes. I measure at the estimate so you get a figure for your actual walls or attic.
How long do we have to stay out of the house after closed-cell spray foam?
Plan on everyone, kids and pets included, being out while we spray and for at least 24 hours after, which is what federal safety guidance says. That wait is the re-entry time, when it's okay to come back inside. Most families book a night away and pack for the pets, and we let you know when it's time to come home.
Is spray foam insulation safe if someone in my house has asthma?
Federal safety guidance says anyone with asthma, respiratory allergies, skin conditions or a past reaction to isocyanates, a chemical in spray foam, should read the product information carefully and consider another insulation if needed. The same guidance says to talk through safety steps with your contractor, since fumes vary with the foam and the house. Tell me at the estimate and we'll go over it together before you decide.
Can closed-cell foam go under the roof deck in my attic?
Yes, and when an attic is closed off with no vents so the ducts sit in cooler air, building research for humid climates says the roof needs spray foam under the deck or rigid foam on top of it. The foam keeps moist indoor air from reaching the roof wood. That research counts on a roof with no leaks and dry wood before spraying, which is why the roof gets fixed first.
Does spray foam insulation have to be covered after it's installed?
Yes, in most spots, because federal weatherization guidance says spray foam is separated from living space by a thermal barrier such as drywall. An attic you store things in gets that same barrier, while an attic you only go into to reach equipment gets an ignition barrier, a thinner fire-resistant covering. I'll tell you which one your space calls for when I look at it.
