Spray Foam Cost Calculator

Open-cell runs $0.50–0.65 per board foot (one square foot at one inch thick). Closed-cell runs $1.15–1.35. Most residential jobs land between $1,500 and $4,000. We provide an exact quote based on your project details, or use our online calculator for a quick estimate.

Yes. Warehouses, metal buildings, manufacturing facilities, cold storage, offices, pole barns, restaurants, and new construction. We work with property owners, builders, GCs, and facility managers. Commercial and industrial buildings often see the biggest improvement because of larger surface areas and more air leakage points.

A standard attic or crawl space takes 4–6 hours. Most residential projects wrap up in 1–2 days. Larger commercial jobs may take 2–3 days. Harbour Spray Foam provides a timeline with your estimate.

No. We mask all surrounding surfaces before spraying. The foam cures in seconds. No dripping or running. Overspray is trimmed flush. We clean the work area before we leave.

Open-cell (R-3.6/inch) is lighter, more affordable, and excellent for sound dampening. Best for attics and interior walls. Closed-cell (R-6.5/inch) is denser, blocks moisture, and adds racking strength to framed assemblies. Best for basements, crawl spaces, and exterior applications. We recommend the right type based on your project.

We stand behind our work. If there's an issue with coverage or adhesion, we come back and fix it. Spray foam doesn't sag, compress, or degrade the way fiberglass does. Once it's sprayed, it stays exactly how we left it. No maintenance, no re-insulation.
