South MS Spray Foam is locally owned and operated. When you call, you talk to the people who will actually be in your attic, not a dispatcher three states away. We live here, we heat and cool our own homes through the same winters and summers, and that's why we don't cut corners on the part you can't see.
📞 (601) 555-0100Fiberglass slows heat but lets air leak straight through. Spray foam fills every gap as it insulates, so the air you pay to cool stays inside.
Open-cell where you want air sealing and sound control, closed-cell where moisture, raised floors or metal buildings call for it. We don't sell one foam for everything.
Our crew works on HVAC systems every day, so we insulate with the AC and ductwork in mind, not just the R-value on paper.
Trained crews in full protective gear, with the area sealed off and ventilated. We tell you exactly when it's safe to come back in.
New builds, older homes, raised floors, metal shops, barns and commercial buildings, from Jackson to the Coast.
Every area, the foam type and the thickness, in writing, before any work starts. No surprises on install day.
We look at your attic, basement and problem rooms, check for moisture, and measure every area.
Foam type, thickness and R-value for each area, and the price, all in writing. No pressure.
We protect and seal off the space, then spray to the quoted thickness, checking depth as we go.
The foam cures and the space ventilates for about 24 hours. Then we walk you through the finished job.
Spray foam is priced by the board foot: one square foot, one inch thick. That makes the cheapest bid easy to spot. It's almost always thinner foam, the wrong foam for the spot, or a quote that leaves out the ignition or thermal barrier your space needs.
We're not the cheapest, and we're not trying to be. Your written quote lists every area, the foam type, the thickness and the R-value, and we check depth as we spray. The number we quote is the number you pay.

Most bad spray foam jobs go wrong for the same few reasons. Here’s what to check before you hand anyone a deposit:
Open-cell and closed-cell do different jobs. A good installer tells you which goes where and why, instead of quoting one foam for the whole house.
A quote should list the foam type and the thickness for each area. A low price with no thickness listed usually means thin foam.
In a Southern home the ducts usually run through the attic. Sealing the attic changes how the system works, so ask whether the installer understands HVAC.
Foam in attics, crawl spaces and living areas may need a protective coating or covering, depending on how the space is used. A pro knows the local requirements.
Foam isn't a fix for a leaking roof or standing water in a crawl space. A good installer checks for moisture and tells you if something needs repair before spraying.
Locally based and insulating homes and buildings from the Jackson metro to the Gulf Coast, plus Mobile and Slidell.
Spray foam gets sold as a miracle and dismissed as overkill, and the truth is in between. Here's the plain-English version: what it is, where it pays off in a hot, humid climate, how it's quoted, and how to tell a good installer from a bad one.
Spray foam is sprayed as a liquid that expands into every gap and cures into a solid layer. That matters because most wasted energy in a house isn't heat moving through insulation. It's air leaking through gaps around lights, vents, wiring, top plates and rim joists. Fiberglass and loose fill slow heat but let air pass straight through. Spray foam stops the air and insulates at the same time.
Open-cell foam is light and soft, around R-3.5 to R-3.8 per inch. It air-seals, absorbs sound and costs less per inch, so it's the usual choice under attic roof decks and in interior walls. Closed-cell foam is dense and rigid, around R-6 to R-7 per inch. It resists moisture, acts as a vapor retarder at about 1.5 to 2 inches, and adds strength, so it's the choice for crawl spaces, basement rim joists, thin walls and metal buildings. Many homes use both.
In South Mississippi the biggest win is almost always the attic, because that's where the summer heat gets in and, in most homes, where the ducts and air handler live. Sealing the roofline with foam keeps the ducts in cool, conditioned air instead of 130-degree attic air. Crawl spaces and raised floors are next, since humid air under the house leads to sweating ducts and musty smells. Open walls in a new build or addition are another, because you only get one chance to insulate them well, and for shops and metal buildings, closed-cell foam is the standard way to stop condensation. ENERGY STAR estimates homeowners save an average of 15% on heating and cooling costs by air sealing and adding insulation.
Spray foam is priced by the board foot: one square foot, one inch thick. What moves the number is the area, the foam type, the thickness and whether the space needs a protective barrier, so we don't quote over the phone. We measure in person and give you a free written quote that's firm before work starts.
Spray foam is safe once it's cured, but the application is a job for trained installers with the right gear and ventilation. Everyone in the home, including pets, stays out while we spray and for about 24 hours afterward. Depending on the space, building codes may require an ignition or thermal barrier over the foam, and we include that when it applies.
Ask which foam goes where and why, what thickness and R-value you're getting in each area, how long you'll need to stay out, and whether the quote includes any required barrier. If a bid can't answer those clearly, the low price is usually buying you thin foam.
