2026 pricing guide for open cell & closed cell spray foam in Lincoln, Nebraska — attics, crawl spaces, basements, and full homes.

Spray Foam Cost by Foam Type
The biggest factor in your project cost is whether you need open cell or closed cell spray foam. For Lincoln homes in Nebraska's climate zone 5A, the choice depends on where you're insulating.
| Application | Open Cell Cost | Closed Cell Cost | Recommended |
|---|---|---|---|
| Attic (1,500 sq ft home) | $3,500–$6,500 | $5,000–$9,000 | Open cell |
| Crawl space encapsulation | Not recommended | $3,000–$7,000 | Closed cell required |
| Rim joists | Not recommended | $800–$2,000 | Closed cell required |
| Basement walls | Not recommended | $3.00–$5.00/sq ft | Closed cell required |
| Interior walls | $1.50–$3.00/sq ft | $3.00–$5.00/sq ft | Either (open cell preferred for cost) |
| Full home (2,000 sq ft) | $8,000–$14,000 | $12,000–$20,000 | Hybrid (open cell attic, closed cell crawl) |
What Factors Affect Spray Foam Cost in Lincoln?
1. Foam Type (Biggest Factor)
Closed cell foam costs roughly double open cell per square foot. In Nebraska, closed cell is non-negotiable for crawl spaces, basements, and rim joists due to moisture requirements. Open cell is the cost-effective choice for attics and interior walls.
2. Square Footage and Access
Most Lincoln contractors price by the board foot (a 1-square-foot area sprayed 1 inch thick). Larger projects cost less per square foot. Tight attic access, low crawl spaces, or obstacle-heavy areas add labor time and cost.
3. Existing Insulation Removal
If your crawl space has old fiberglass batts that need removal before spray foam application, expect to add $500–$1,500 to the project cost. Many Lincoln homes built before 1990 have degraded fiberglass in crawl spaces.
4. Thickness Required
Nebraska's zone 5A requires R-49 in attics (about 13–14" of open cell), R-15 minimum in crawl space walls (about 2–2.5" of closed cell), and R-15 in rim joists. More inches = more material = higher cost.
