Moisture-first

Built for Gulf Coast humidity and storm rebuilds

The cheapest time to insulate right is during the build

When a home is still open framing, every cavity is accessible and the spray foam crew can seal the entire envelope cleanly: walls, roof deck, rim joists, and any tricky transitions. Doing it now costs a fraction of what a retrofit costs later, and it produces a tighter, better-performing house than you can achieve after the drywall goes up.

For Southwest Louisiana builders, foam is the obvious envelope choice. A foam-sealed home keeps the humid Gulf air out, cuts the cooling load dramatically, and protects the structure against the moisture that defines this climate. With so much of the region in an active rebuild cycle, getting the envelope right the first time is the difference between a comfortable, efficient home and one that fights humidity for decades.

We work directly with builders and owner-builders to spec the right mix of closed-cell and open-cell foam, coordinate around the construction schedule, and hit the performance targets for climate zone 2. Bring us in early and we will help you build the tightest home on the street.

Common questions

Why use spray foam in new construction instead of batts?+

Foam air-seals the whole envelope in one step, which batts cannot do. In a humid climate that air seal is what controls moisture and slashes the cooling load. Doing it during the build is also far cheaper than retrofitting later.

When in the build should the foam go in?+

After rough-in for plumbing, electrical, and HVAC, and before insulation inspection and drywall. We coordinate with your schedule so the timing lines up with the other trades.

Do you work with builders and owner-builders?+

Both. We help spec the foam package for code and performance, then schedule the install around your construction timeline.

How much does spray foam add to a new build?+

Full-envelope foam typically runs $5,000 to $15,000 or more depending on the size of the home and the foam mix. You get an itemized quote tied to your plans.
