| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Bowling Green attics run hot all summer, and vented attic framing is common across town. We seal top plates, penetrations, and framing gaps with closed cell foam so Fountain Square bungalows and newer Plano subdivisions stay cooler and quieter through the mixed-humid heat. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Bowling Green basements and crawl spaces sit on limestone and stay damp long after storms pass. We spray closed cell foam on rim joists and block walls near Fountain Square and Alvaton to block moisture and add rigidity. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Open cell foam fills wall cavities and attic rafters across Bowling Green's mixed-humid climate zone 4A. We use it in student rental walls near WKU and two-story framing in Alvaton subdivisions to soften noise and cut drafts without overfilling cavities. |
| Wall & Injection Foam Insulation | From $2/sq ft | Older homes near Fountain Square often have closed wall cavities with no insulation at all. We drill small holes and inject foam into these cavities in Fountain Square bungalows and mid-century ranches without opening up the walls. |
| Crawl Space Spray Foam Insulation | From $2,500 | Crawl spaces dug into Warren County limestone stay damp for days after spring storms move through. We spray closed cell foam across walls and the band joist so moisture stops rising into floors above. |
| Rim Joist & Band Joist Spray Foam | From $650 | Rim joists around Bowling Green homes take a beating from cold snaps and winter ice each year. We spray closed cell foam along the band joist in basements and crawl spaces across Warren County to stop drafts and block moisture. |
| Garage Spray Foam Insulation | From $1,200 | Garages across Bowling Green subdivisions swing from summer heat to winter cold snaps fast. We foam garage walls and ceilings in Alvaton and Plano homes, especially rooms over garages that need steadier temperatures year round. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Barns and shops scattered across Warren County toward Smiths Grove sweat and drip without a proper air barrier. We spray closed cell foam across metal panels and trusses so moisture stops condensing inside shops and barndominiums near Smiths Grove. |
| Commercial & New Construction Spray Foam | Free commercial estimate | New subdivisions pushing toward Plano and Alvaton give us a chance to foam two-story framing before drywall goes up. We handle whole-building foam for commercial shells and new builds across Warren County before insulation deadlines close walls. |
| Insulation Removal | From $950 | Flattened attic insulation in Bowling Green's mid-century ranches no longer does much in summer heat. We remove old fiberglass or cellulose from attics and crawl spaces near Fountain Square before spraying new foam. |
| Insulation Replacement & Re-Insulation | From $2,800 | Bowling Green homeowners often replace flattened attic insulation and foam crawl spaces in the same visit. We pair removal with new spray foam across attics, crawl spaces, and rim joists in homes from Fountain Square to the newer Alvaton subdivisions. |
| Air Sealing | From $650 | Air leaks at top plates and penetrations drive up cooling bills in Bowling Green's hot humid summers. We seal gaps in attics and crawl spaces across Warren County with foam and caulk, cutting the stack effect that pulls in winter drafts. |
What Affects the Price
- Project Size and Square Footage : Larger projects typically benefit from better per-unit pricing. Attic and metal building work is priced per square foot, while closed and open cell foam is priced per board foot, affecting your total investment.
- Foam Type Selection : Closed cell foam ($1.20/board ft) provides superior R-value and moisture resistance, while open cell foam ($0.55/board ft) is more budget-friendly and offers excellent soundproofing for interior applications.
- Accessibility and Existing Conditions : Difficult-to-reach areas, existing insulation that needs removal, or structural obstacles may affect labor time and final pricing. Our estimate accounts for your home's unique layout.
- Insulation Removal and Preparation : If old insulation must be removed before new foam is installed, this adds to the project cost. Removal services start at $950, and full replacement packages begin at $2,800.

Pricing FAQ
Why do spray foam insulation prices vary so much between projects?
Pricing depends on multiple factors: the size of the area being insulated, whether you choose closed cell or open cell foam, how accessible the space is, whether existing insulation needs removal, and the complexity of air sealing work. Two homes may have different square footage, existing conditions, or insulation needs, which is why each project requires a customized quote.
