The Best Spray Foam Insulation in the South Carolina Lowcountry
Locally owned and serving the South Carolina Lowcountry and coastal Georgia since 2005. We provide high-performance spray foam insulation, crawl space encapsulation, and attic insulation designed to manage coastal humidity, improve indoor comfort, and reduce monthly energy costs.
Solutions for Bluffton’s Toughest Home Challenges
From relentless coastal humidity to the threat of seasonal storms, Lowcountry homes face unique environmental demands. We provide high-performance spray foam solutions engineered to seal out moisture, slash energy costs, and fortify your home’s structure against the elements.
Professional Spray Foam Insulation
Maximize energy efficiency with a superior air seal. We replace leaky fiberglass with high-performance spray foam to eliminate hot spots and reduce HVAC strain. Upgrading now secures a $1,200 annual federal tax credit and delivers year-round comfort for your Bluffton home.
Coastal Moisture & Mold Prevention
Seal your crawl space against Lowcountry humidity. Bluffton’s marshland air causes wood rot and musty odors that traditional insulation can’t stop. Our closed-cell foam creates a total vapor barrier that can significantly reduce crawl space humidity levels, and helps prevent mold growth and pest intrusion.
Hurricane Hardening & Storm Protection
Reinforce your home’s structure significantly.
In a coastal storm, strength matters. Our closed-cell installations provide a FEMA-rated flood barrier and massive structural reinforcement, protecting your family from high winds while potentially lowering your insurance premiums.

Highly recommend!
We recently had our attic insulated by Island Spray Foam and couldn’t be more pleased with the experience. From start to finish, the team was professional and efficient while spraying our attic. Jose and his crew did a fantastic job. They also did a thorough cleanup—you’d never know they were here. Highly recommend them if you’re looking for quality spray foam insulation and a crew that truly takes pride in their work!

Thanks Jose and team!!
Jose, and his team were excellent from start to to finish. I contacted Island Spray Foam for a quote to install new fiberglass batt insulation under my villa. Jose showed up same day to inspect and provide a quote. Quote was received later that day. After a little back and forth with questions and adjustments, all looked reasonable, so agreed to the work. The job started the next day and was finished on time and on budget. I should also note the next day was a cold day in the low country and there was a marked improvement in the warmth of my home. Thanks Jose and team!!
