Why spray foam works in Valley homes

Spray foam is applied as a liquid and expands to fill the cavity, sealing the gaps that batts and blown-in cannot reach. In the Valley that matters twice over: it stops the heat radiating down from a 150-degree attic, and closed-cell foam doubles as a moisture barrier during our humid months and hurricane season.

We install both open-cell and closed-cell foam, and we will tell you honestly which one your home needs. On some jobs a blown-in top-up is the better value, and we will say so.

spray foam questions

How much does spray foam cost?

Roughly $1.50 to $4.50 per board foot depending on open-cell or closed-cell, thickness, and attic access. We quote the exact figure in writing after an in-home inspection.

Do I have to leave the house during the install?

We ask you to stay out of the work area while we spray and for a few hours after. Most homeowners are back in the same evening.

Is spray foam worth it over blown-in?

It depends on your home. Foam seals air leaks that blown-in cannot and gives more R-value per inch, but blown-in is a strong, lower-cost option for many Valley attics. We will tell you which makes sense for yours.

Ready for a cooler house and a smaller electric bill?

Tell us about your home and we will come out, inspect your attic and walls, and give you a clear written estimate. Free, no pressure. Hablamos español.
