Serving Eagle and nearby communities.

New Construction Spray Foam Insulation covers the full shell: roofline, walls, and rim joists. We time it with the framing schedule, before drywall goes up. Eagle's growth in the foothills keeps this work steady. Most new custom builds in the area are foam-ready from the design stage.

Eagle Spray Foam Insulation coordinates directly with builders and homeowners to land the foam step at the right window: after framing, before the insulation inspection. That timing matters more than almost anything else on a new build.

FAQs

New Construction Spray Foam Insulation FAQs

How much does new construction spray foam cost in Eagle?

Full shell packages typically run $1.50–$2.50 per square foot of foam coverage, depending on foam type and how much of the shell is included.

When in the build schedule should foam happen?

After framing is complete and rough-ins are done, but before drywall. Most builders schedule us right alongside the insulation inspection.

Do permits cover the spray foam step?

Yes. Foam insulation on new construction typically falls under your general building permit, not a separate one.

Can I mix open-cell and closed-cell on one build?

And most builds do. Closed-cell goes where moisture or R-value demands are higher, open-cell fills the rest.

Is DIY an option on new construction?

No. Full shell coverage needs rig-grade equipment for even expansion and correct thickness across walls, roofline, and rim joists in one pass.

What happens if foam isn't ready in time for inspection?

We work directly with your site supervisor to avoid that. If the schedule shifts, tell us early and we'll adjust.

Cost

What does a new construction spray foam cost in Eagle?

Pricing scales with square footage and how much of the shell gets foam versus other insulation types.
