Is open-cell spray foam right for your Columbia home?
Open-cell foam insulation is a soft spray foam that expands to fill gaps and cavities, so it stops drafts and slows heat in the same pass. Heatwise Columbia Insulation Company installs it in attics, walls and rim joists in Columbia, MO and the cities around it, including Jefferson City, Fulton, Moberly and Boonville.
Most calls for open-cell foam start with a hot upstairs, a drafty older house or a remodel with the walls opened up. The price moves with how many square feet we're covering, how many layers go on and how easy the space is to work in. The schedule usually turns on anything that has to be fixed first, like a roof leak, and on picking a day when everyone can be out of the house. Every estimate is written out with the areas, materials and steps, so you see your own number and what it pays for, and if closed-cell foam or loose fill suits your house better, I'll say so.
How do you know your house could use open-cell foam?
Upstairs stays hot
If the bedrooms upstairs run warmer than the rest of the house all summer, attic air is usually leaking down through gaps the old insulation never covered. Every summer you wait, the AC runs longer to fight it and the power bill shows it.
Cold floors and drafts
Cold air along the baseboards or floors that feel chilly in winter usually means air is slipping in where the house sits on the foundation, often from the crawl space or basement. Left alone, the furnace works harder and those rooms never feel warm.
Noise comes right through
If you can hear the TV from the next room or every car door in the garage below, the wall or ceiling is likely empty or thinly filled. Open-cell foam soaks up a lot of that sound, and it's easiest to add while studs are open during a remodel.
Work that often goes with it
Commercial insulation
For property managers whose tenants complain about drafts or noise between units, offices or shops.
Crawl space vapor barrier
For a damp dirt crawl space, where a sheet across the ground keeps moisture down before anything gets insulated above it.
How we install open-cell foam insulation
Open-cell is our pick when you want air sealing and quieter rooms at a lower cost than closed-cell, and before we recommend it, we ask whether anyone at home has asthma or allergies. Foam costs more than loose fill, so for an attic floor with no ductwork above it, sealing the gaps and topping up blown-in insulation, loose fill blown through a hose, usually does the job for less, and I'll tell you that. When foam is the right call, our crew covers floors and anything nearby, pulls out old insulation that's soaked or full of droppings so the problem doesn't stay, seals the hatch and the larger openings, sprays the foam, trims it flush with the framing and cleans up before you come home.
The same approach works in bigger buildings, and our commercial insulation work handles offices, shops and rentals for property managers. When we foam the rim joists over a damp dirt crawl space, we often pair it with a crawl space vapor barrier so ground moisture isn't working against the new insulation.
Under the attic roof deck
This suits attics where the ductwork or furnace lives up there, because sealing the roofline brings that equipment inside the insulated part of the house. If your ducts aren't in the attic, loose fill on the floor is usually the better buy.
Open wall cavities
This suits remodels and additions with the studs still exposed, since the foam fills around wires and boxes and quiets the room. Once drywall is up, filling the wall is harder and costs more.
Rim joists
This suits drafty basements and crawl spaces, where the wood band sitting on top of the foundation leaks a lot of air. One pass of foam seals that band and insulates it at the same time.

I measure every job myself
I spent my first years in this trade selling jobs I couldn't explain from start to finish, so now I come out, measure and write every estimate myself. You talk to the person who actually saw your attic, and I'm the one who checks the finished work with you.
Problems fixed before foam goes in
If your roof leaks or the old insulation is wet, I'll tell you that needs fixing first instead of burying it under new foam. Foam sprayed over a problem just hides it until it shows up in the framing.

Common questions
How do I choose between open-cell and closed-cell spray foam for my house?
Pick open-cell when price and sound matter most, and closed-cell when you need the most insulation in a thin space. Closed-cell is about twice as energy efficient per inch, while open-cell costs less, blocks sound much better and still lets water vapor pass through. I'll look at where the foam would go before pointing you to either one.
How much does open-cell spray foam cost in Columbia, MO?
Open-cell spray foam in Columbia usually costs about $1,800 to $2,700 for 1,000 square feet sprayed 3 inches thick. It sits at the lower end of local spray foam prices, with closed-cell at the upper end, and it tends to run higher in a finished home, when old insulation has to come out, when foam is injected into closed walls or when the attic is hard to reach. Your written estimate shows which of those apply to your house.
How thick is open-cell foam in walls and attics?
Walls usually take one layer of open-cell foam, which expands to about 3 inches, while attics often have room for two layers. Because one layer is as far as open-cell goes in a standard wall, closed-cell is worth comparing if you want more insulation there.
How long does it take before I can go back in the house after spray foam?
Some foam makers recommend 24 hours before anyone returns, though the time varies by product, so plan on a full day away. The EPA's guidance on vacating and re-entry says to arrange a place for everyone in the home to stay during the install, pets included. Ask us the re-entry time for the product we plan to use, and we'll set the day around it.
Is open-cell spray foam safe if someone in my home has asthma?
It may not be the right choice for your house. The EPA advises people with asthma, respiratory allergies, skin conditions or a past sensitivity to isocyanates, the chemicals that make spray foam react, to review the product information carefully and consider other insulation. If that's your household, tell me at the estimate and we'll look at options without foam.
Does a sealed attic need anything extra with open-cell foam?
Yes, an attic with no outside vents needs a way to remove moisture once foam goes under the roof deck. Any furnace or water heater burning fuel up there should be a sealed-combustion unit that vents straight outdoors, so mention what's in your attic when I come out.
