Spray foam insulation and air sealing offer superior energy efficiency for Fargo homes, from attics and crawl spaces to rim joists, garages, and metal buildings. Pricing varies based on the square footage of your space, the type of foam (closed cell or open cell), accessibility, and the complexity of your project. We're transparent about costs so you can make an informed decision for your home's comfort and energy savings.

| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a Fargo attic that swings from summer heat to 30 below into conditioned space. The ductwork ends up inside the envelope. Every estimate lists the R-value target; the thickness per pass; the board footage. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Two-pound closed-cell foam delivers R-6.5 per inch with its own vapor retarder and real structural stiffening. The right product for basement foundation walls; rim joists; shops and Quonsets and any wall that has to stand up to a North Dakota January. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Half-pound open-cell foam air-seals attics and walls at a friendlier price per board foot. Sound dampening between rooms and between twin-home units comes with it. We spell out where it belongs, and where a basement wall calls for closed cell instead. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. The retrofit answer for Fargo's older frame homes in Hawthorne and Horace Mann and 1950s-60s ranches with empty cavities. Ports go under a siding course and are patched; fire blocking is checked first. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on crawl space walls under additions and older homes ends the frozen floors of a Fargo January. Moisture and drainage problems get fixed first, we never spray over a wet crawl space. |
| Rim Joist & Band Joist Spray Foam | From $650 | Basement rim joists leak more cold air than almost anything in a Fargo house, and at 30 below you feel it. Closed cell seals every bay along the foundation; the fastest comfort payback. Bi-level and split-entry rims are handled the same way. |
| Garage Spray Foam Insulation | From $1,200 | Heated garages are a necessity in Fargo, and foam is what lets one hold its heat through a long winter. Ceilings under bonus rooms and walls shared with the house are foam-sealed against deep cold; workshop and heated-garage conversions are handled the same way. The difference between a cold box and usable space all winter. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam is the insulation that stops a North Dakota shop from frosting inside and dripping at every thaw. Post-frame shops; Quonsets; machine sheds and heated farm shops sealed against condensation across the Red River Valley. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; offices; churches and production builders served on schedule. Code-compliant assemblies come with documentation your building inspector will actually accept. Phased work keeps your operation running from the Fargo industrial parks to West Fargo and Horace. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Material soaked by an ice dam leak comes out with it. We also cut out failed spray foam; the job most installers will not touch. Vermiculite gets flagged for testing. |
| Insulation Replacement & Re-Insulation | From $2,800 | The full reset: old material removed; gaps air-sealed; new foam installed to current code R-values. The right call when insulation is flattened; mouse-fouled; soaked by an ice dam leak or simply twenty years past its job. |
| Air Sealing | From $650 | Top plates, can lights, chimney chases and attic hatches leak more heated air than most walls do. That warm leak is what builds ice dams. We seal them before insulating, the cheapest comfort fix in a Fargo house. |
What Affects the Price
- Project Size and Square Footage : Larger areas typically cost less per unit because equipment setup and labor are spread across more space. Attics, crawl spaces, and wall cavities are measured differently, which affects your final price.
- Foam Type: Closed Cell vs. Open Cell : Closed cell foam (starting at $1.20/board ft) provides superior R-value and moisture resistance, while open cell foam (starting at $0.55/board ft) is more affordable and still highly effective for most Fargo applications.
- Accessibility and Site Conditions : Tight attics, finished spaces, or areas requiring special equipment access may increase labor time and costs. We assess your specific layout during the estimate to give you accurate pricing.
- Existing Insulation Removal : If old insulation must be removed before new foam is applied, this adds to your project cost. Removal typically starts at $950, depending on the volume and type of material.

Pricing FAQ
Why do spray foam insulation prices vary so much between projects?
Costs depend on several factors: the size of your space, the type and thickness of foam needed, whether existing insulation must be removed, and site accessibility. A small rim joist project is very different from a full attic spray foam installation, so each estimate is customized to your home's unique needs.
