Galveston Spray Foam Insulation FAQs

Is spray foam good for island humidity and salt air?
Yes—foam creates a tight air/vapor control layer that helps reduce humid, salty air infiltration.

Do you insulate pier & beam homes?
Absolutely. Closed-cell under the floor or open-cell in conditioned assemblies—built to code with proper barriers.

How long does a typical project take?
Most single-family homes finish in 1 day; larger or complex properties can take 2–3 days.

Which foam type do you recommend here?
Closed-cell for crawl spaces/exterior walls; open-cell for attics and interior sound control.

Will it help with energy bills?
Yes—air sealing and continuous insulation typically lower cooling loads and improve comfort.

Can you coordinate with my builder or HOA?
We coordinate with GCs/trades and can provide documentation as needed for HOAs or inspections.
