Spray Foam Insulation in Moline, IL
Closed-cell and open-cell spray foam — air seal and insulation in one pass.
Why Moline homes need spray foam
Moline's brick bungalows and post-war ranches are an almost perfect fit for spray foam: small attics where R-value matters per inch, and uninsulated rim joists that air-seal beautifully in an afternoon. Local contractors have worked in South Park, Prospect Park, and most of the new builds south of John Deere Road.
Spray foam is the only insulation product that air-seals AND insulates in a single application. Closed-cell foam delivers R-6.5 to R-7 per inch and stops bulk water; open-cell foam delivers around R-3.7 per inch at lower cost and is ideal for interior walls and attic roof decks. Either way, you eliminate the air leaks fiberglass batts can never address.
We spray attics, walls (during remodels), rim joists, crawl spaces, pole barns, and commercial buildings. Every job starts with a free in-person walk-through, a written line-itemed quote, and full prep — masking, plastic, and respirator-rated PPE for the crew.

Spray Foam Insulation FAQ
What does spray foam cost?+
Most projects land between $1.50 and $4.00 per board foot installed, depending on open-cell vs closed-cell and access. Typical attic jobs run $2,500–$6,500. Your contractor will give a written quote after a free in-home walk-through — never high-pressure phone estimates.
Open-cell or closed-cell — which do I need?+
Closed-cell for anywhere moisture or contact with concrete is a concern (crawl spaces, rim joists, basement walls, exterior applications). Open-cell for interior walls and most attic roof decks where you want sound dampening and a lower price per inch. Your contractor will recommend the right product on the walk-through.
Is spray foam safe once it's cured?+
Yes. Once spray foam has fully cured (typically 24 hours), it's inert and safe to re-enter. Your contractor will use only modern HFO-blown formulations with no ozone-depleting blowing agents. We also keep the home unoccupied during install and for 24 hours after.
How long does spray foam last?+
Properly installed spray foam is permanent — it doesn't sag, settle, or lose R-value over time the way fiberglass and cellulose do. We back our installs with a written warranty.
