Spray Foam Insulation in Bay St. Louis, MS

Spray foam insulation in Bay St. Louis works in a town shaped by Katrina's final landfall. On August 29, 2005, the storm came ashore just west of the city, at the mouth of the Pearl River, with a storm surge of about 28 feet. A ridge along the old route of Highway 90 sits at about 25 feet in elevation and was spared inundation. The 2020 census counted 5,447 housing units, 22.0 percent vacant, reflecting second homes and seasonal use.

Older homes on the ridge

Cottages and older houses on higher ground often have crawl spaces, wood floors and patched attics. Encapsulation or floor foam, plus attic sealing and depth, usually does the most good.

Raised homes by the water

Rebuilt homes near the beach are often raised. Closed-cell foam under the floor seals and insulates.

Comparing quotes

Ask each insulation contractor for the same details: material, depth, R-value and price per area. Our quotes are written that way.

Ductwork

Where ducts run through a hot attic, sealing them helps the AC hold the house at temperature while you are away.

Second homes

With many houses empty part of the year, sealing helps hold humidity down while the AC is set back. Get a free estimate
