| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Open-cell foam on the roof deck turns a 150°F Fayetteville attic into conditioned space. The air handler and ductwork that so many Sandhills homes run overhead end 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. It shrugs off flood water. The right product for crawl space walls; poultry houses; metal buildings and any wall facing Carolina humidity. |
| 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 duplex units comes with it. We spell out where it belongs, and where a crawl space or flood-prone floor calls for closed cell. |
| Wall & Injection Foam Insulation | From $2/sq ft | Injection foam fills closed walls through small drilled ports, no demolition. The retrofit answer for Massey Hill mill houses; Haymount bungalows and 1950s-70s brick-veneer ranches with empty cavities. Ports go under a siding course or along a mortar joint and are patched. |
| Crawl Space Spray Foam Insulation | From $2,500 | Closed-cell foam on crawl space walls and rims holds back humid air over sandy Sandhills soil. Moisture is fixed first and we leave the inspection strip your termite bond calls for. |
| Rim Joist & Band Joist Spray Foam | From $650 | Crawl space rims, cantilevers and floors over garages leak conditioned air at every framing gap. Closed cell seals them for good, the small-ticket job with the fastest comfort payback in a Fayetteville house. |
| Garage Spray Foam Insulation | From $1,200 | Garage ceilings under bonus rooms and shared house walls get sealed against radiant afternoon heat. Workshop conversions are handled the same way. The difference between a storage oven and usable space. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Closed-cell foam is the insulation that stops a Carolina metal building from sweating. Poultry houses; farm shops; barndominiums and old tobacco-country ag buildings sealed against condensation from Sampson and Bladen County farms to Harnett County acreage. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Warehouses; offices; churches and production builders served on schedule. Code-compliant assemblies come with documentation your local inspector will actually accept. Phased work keeps your operation running from the Interstate 95 warehouse belt to the fast-growing subdivisions around Fort Bragg. |
| Insulation Removal | From $950 | Old blown-in and batts vacuumed out before any new foam goes in, never buried. Flood-soaked material and squirrel nests come 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; rodent-fouled; soaked by a hurricane roof leak or simply twenty years past its job. |
| Air Sealing | From $650 | Top plates; can lights; chases; knee walls and attic hatches leak more cooled air than most walls. We seal the leaks before insulating, the step that makes every R-value actually perform and the cheapest comfort fix in a Fayetteville house. |
What Affects the Price
- Project Size and Square Footage : Larger areas typically cost less per square foot due to economies of scale, while smaller, specialized projects may have higher per-unit costs.
- Foam Type (Closed Cell vs. Open Cell) : Closed cell foam is denser and more expensive but offers superior R-value and moisture resistance. Open cell foam is more affordable and still provides excellent insulation for many applications.
- Accessibility and Structural Complexity : Hard-to-reach areas, tight spaces, and complex roof geometries require more time and care, which can affect your final price.
- Existing Insulation Removal and Cleanup : If old insulation must be removed before new spray foam is installed, this adds to the project cost but ensures a clean, effective installation.
