Growth, Rain and Rentals
Spray foam insulation in Franklin has a lot of homes to work with. Franklin grew from 8,408 residents in 2010 to 10,176 in 2020, a 21% increase, with 4,353 housing units counted in 2020. Census QuickFacts lists a 55.0% owner-occupied rate for 2020 to 2024, so there is a sizable rental market too.
A wet climate
Franklin's 1991 to 2020 normals show about 50.5 inches of precipitation and only 4.3 inches of snow a year, with May the wettest month. That much rain is hard on crawl spaces. Before we encapsulate, we look at gutters, grading and any signs of water in the crawl space.
More jobs, more homes
In December 2025, Kroger announced an automated distribution center in Franklin expected to add about 430 full-time jobs. New residents mean new construction and more homes changing hands, which often brings inspection findings about attic and crawl space insulation.

Franklin Questions
Does all that rain mean my crawl space needs encapsulation?
Not automatically. Encapsulation helps with humidity, but water coming in during storms needs drainage work. We check both.
Do you work for landlords in Franklin?
Yes. We can quote the most effective work first and leave the rest for later.
Are Kentucky and Tennessee codes different?
Yes. Franklin homes fall under Kentucky's code. We work to the targets on the Kentucky side.
How long does crawl space encapsulation take in Franklin?
Most homes take one to three days, depending on the size of the crawl space, how much old insulation and debris has to come out, and whether the floor is level or rocky. We give you a time estimate with the written quote.
