Crawl Space Encapsulation on the Northshore: Why Raised Homes Need Closed-Cell Foam
Raised pier-and-beam homes define the Northshore landscape—from historic Covington blocks to lakefront Mandeville properties and Slidell neighborhoods near the I-10 corridor. Under every one of these homes is a crawlspace that battles Louisiana humidity 365 days a year.
The Northshore Crawlspace Problem
Ground moisture, Lake Pontchartrain humidity, and poor ventilation combine to create mold, wood rot, and musty indoor air in raised homes. Fiberglass batts absorb this moisture like a sponge and sag within months. Closed-cell spray foam is the only permanent fix.
Why Closed-Cell Foam Is Required Below Raised Homes
- 100% moisture barrier: Blocks ground humidity from reaching subfloors
- Structural adhesion: Bonds to floor joists and rim joists for added rigidity
- Pest deterrent: Seals gaps where rodents and insects enter pier-and-beam foundations
- Energy seal: Stops conditioned air from escaping through the floor system
What Encapsulation Includes
A full crawlspace encapsulation on the Northshore typically includes cleaning the space, applying 2 inches of closed-cell foam to the subfloor and rim joists, and sealing all penetrations. Most installs are completed in a single day with a 24-hour re-entry window.
