Insulation for the Old Big Swamp
Spray Foam Insulation in Hayneville works with older homes and rural properties around the Lowndes County seat. Settlers from South Carolina founded the town in 1820, and through the 1820s it was known as "Big Swamp." It became the county seat and took the name Hayneville in 1831, honoring Governor and U.S. Senator Robert Y. Hayne. The town sits at about 230 feet.
Damp ground, damp crawl spaces
Houses built on low ground in a humid climate often have damp crawl spaces. The signs are a musty smell, soft or cupped floors, sweating ducts and fallen insulation. We check drainage, grading and gutters first, because water under the house has to be stopped before any crawl space work. Then we recommend either closing the crawl space or sealing the floor with closed-cell foam.
Small town, older stock
Hayneville's population has stayed small, 1,177 in 2000 and 830 in 2020, so it did not see the subdivision boom of the Montgomery suburbs. Many homes are older and were insulated lightly when built, if at all. Attic sealing and depth, crawl space work and, where walls are open during repairs, spray foam in the walls are the usual jobs.
Rural buildings
Many properties in Lowndes County include barns, shops and equipment sheds. Steel buildings drip condensation in humid weather, and closed-cell foam on the roof stops it. We price the roof and walls separately so you can do what matters most first.
What to expect on cost
National guides offer a range. HomeGuide lists attic insulation jobs at roughly $1,000 to $2,700 and closed-cell foam at $3.00 to $5.00 per square foot. Older homes may need old insulation pulled out first, which HomeAdvisor lists at $1 to $2 per square foot. Every quote breaks out those items so you can see what each part of the job costs, and the written estimate is the final price.

Hayneville Questions
Do you come out to Hayneville?
Yes. We serve Hayneville and the surrounding parts of Lowndes County. Call to set up a visit.
My older house has no insulation in the floor. What should I do?
In a humid area, closed-cell foam on the underside of the floor or a sealed crawl space both work better than fiberglass batts, which tend to sag when damp. We check the crawl space and recommend one.
How much does it cost to insulate a crawl space?
HomeGuide lists spray foam in a crawl space at $2,000 to $4,000 and full encapsulation at $3,000 to $15,000. Your written estimate after the inspection sets the price.
Can you insulate a barn roof that drips?
Yes. Closed-cell foam on the underside of the steel roof stops humid air from reaching the cold metal, which is what causes the drip. Roof leaks at fasteners need separate repair.
