Homes Among the Bayous
Spray foam insulation in Gautier deals with humid ground and humid air. Gautier is a bedroom community surrounded by bayous and wetlands on three sides, at the mouth of the West Pascagoula, or Singing, River. It takes its name from the Gautier family; Fernando Upton Gautier built a homestead at the river mouth in 1867. The 2020 census counted 8,307 housing units, 9.2 percent vacant.
Moisture from below
Houses near wetlands sit over damp soil. Vented crawl spaces pull in humid air that condenses on cool floors and ducts. Encapsulation, or closed-cell foam on the subfloor, cuts that moisture.
Attics and ducts
Most Gautier homes are one-story ranches with ducts in the attic. Sealing ducts and the ceiling, then adding depth, is usually the first fix. Where ducts are extensive, roof-deck foam brings them inside.
Nature next door
The 900-acre Eric Clark Coastal Preserve was established in Gautier in 2023. Wooded and wetland edges mean more rodents and insects looking for a way in; sealing helps there too.
One-story ranch attics
Many Gautier homes are single-story, which means the whole house sits under one attic. Sealing and insulating that one ceiling covers every room. It is often the single most effective upgrade in the house.
