Closed-cell spray foam stops air leaks and moisture in one application - the right choice for Florence crawl spaces, attics, and walls in the Shoals area's humid climate.
Closed-cell foam insulation in Florence is sprayed onto surfaces as a liquid and expands into a firm, dense layer that works as both an insulator and a moisture barrier - most crawl space and attic jobs are completed in a single day. Unlike fiberglass batts or blown-in insulation, it fills every crack and corner it touches and hardens into a material that does not sag, shift, or absorb water over time.
In Florence and across the Shoals area, the humidity and the region's large stock of pre-1980 homes make closed-cell foam particularly well-suited to crawl spaces, rim joists, and attic rafters. It is often installed alongside spray foam insulation projects that cover multiple areas of the home in one visit.
If your electric bill climbs sharply from June through August even while keeping the thermostat steady, your home is likely losing cooled air through gaps in the walls, attic, or crawl space. Florence summers are long and punishing, and an under-insulated home makes your air conditioner work twice as hard.
Florence's proximity to the Tennessee River and its humid climate mean crawl spaces here are especially prone to moisture buildup. If you notice a damp or musty smell from floor vents, or if you see condensation on pipes under the house, your crawl space is not properly sealed.
If one part of your home never quite reaches the temperature the rest of the house holds - a back bedroom that stays stuffy in August, a room over the garage that is freezing in January - that is a sign of uneven insulation or air leakage. These hot and cold spots are one of the most common complaints in older Florence neighborhoods.
Gaps in your home's thermal envelope do not just let air through - they let bugs and rodents in too. If you are seeing ants, roaches, or other pests inside without an obvious entry point, there is a good chance they are coming up through an unsealed crawl space. Closed-cell foam fills those gaps completely.
We apply closed-cell foam to crawl spaces, attic rafters, rim joists, basement walls, and exterior walls across Florence and the Shoals area. For crawl spaces, the foam is sprayed onto the walls and floor joists to create a continuous air and moisture barrier - turning a vented, humid crawl space into a semi-conditioned area that no longer brings outside air into your living space. This is the most common application we do in Florence, and it is why open-cell foam insulation - which is less moisture-resistant - is generally a better fit for interior applications like attic decking rather than crawl spaces.
For attics, closed-cell foam can be sprayed directly to the underside of the roof deck, bringing the attic into conditioned space and eliminating the duct leakage problems that come with HVAC equipment sitting in an unconditioned attic. Rim joist sealing - filling the gap at the very top of your foundation wall where the floor framing sits - is a quick, high-impact upgrade that can be added to almost any project. We also combine closed-cell foam with broader spray foam insulation scopes when a home needs comprehensive coverage in a single visit.
Best for Florence homes with moisture issues, pest problems, or vented crawl spaces that let humid air in from below.
Ideal when HVAC equipment is in the attic and you want to bring the space into conditioned area.
A targeted upgrade for any home losing conditioned air through the gap between foundation and floor framing.
Suits older homes with gaps around pipes and wires where other insulation types cannot seal effectively.
Florence sits in the Tennessee Valley, where summer humidity regularly climbs above 70 percent and temperatures push into the 90s from May through September. That combination means air conditioning systems work hard for more than half the year, and any gaps in your home's envelope translate directly into higher monthly bills. A significant portion of Florence's neighborhoods - including older subdivisions off Huntsville Road and areas near downtown - were built in the 1950s through 1980s with minimal insulation and vented crawl spaces that were never designed to manage today's humidity levels. Homeowners in Huntsville and Decatur face similar conditions and are increasingly choosing closed-cell foam for the same reasons.
Florence's proximity to the Tennessee River also raises ground moisture levels in lower-lying neighborhoods, making crawl space moisture intrusion a genuine concern rather than a theoretical one. Closed-cell foam is the only insulation type that creates a real moisture barrier in those conditions - other types absorb or allow moisture to pass through over time. TVA's EnergyRight program and the federal energy efficiency tax credit may both offset part of the project cost for qualifying Florence homeowners, making the upfront investment more manageable.
We respond within one business day. We ask a few questions about your home - what areas you want insulated, whether you have noticed moisture issues - so the site visit is focused and efficient.
We come out and look at the crawl space, attic, or walls you want treated. We check for moisture, note access conditions, and measure the area. No price is given over the phone - estimates require seeing the space in person.
You clear the work area of stored items before the crew arrives. The foam is sprayed in even passes and hardens within minutes. Most projects are done in two to six hours. Stay out of the treated area for at least two hours after application.
We walk you through the finished work so you can see even, complete coverage. We provide documentation of materials used - important if you plan to claim the federal energy efficiency tax credit.

(256) 367-9903We follow the installation best practices established by the Spray Polyurethane Foam Alliance for mix ratios, application thickness, and coverage consistency. That means no thin spots and no areas where the surface underneath shows through. You can see the quality of the work before we leave.
Spraying foam over an active moisture problem seals the problem inside your wall and makes it worse. Every project we do starts with a moisture check. If there is water intrusion, we tell you before we touch anything - not after the invoice is written.
Florence Insulation has been installing spray foam for Florence, AL homeowners since 2023. Our crews are licensed with the Alabama Licensing Board for General Contractors and know the specific crawl space and attic conditions common in this area's housing stock.
The federal energy efficiency tax credit can cover up to 30 percent of qualifying insulation costs, up to $1,200 per year. We provide the product documentation you need for your tax preparer and flag any TVA EnergyRight rebates available for your project - so you are not leaving money on the table.
We do not subcontract spray foam work. The crew that gives you the estimate is the crew that installs the foam. We invite every customer to look at the finished work before we pack up - because closed-cell foam is inspectable, and we stand behind ours.
