Spray foam insulation and air sealing are highly effective ways to improve your home's energy efficiency, comfort, and indoor air quality in Savannah. Whether you're insulating an attic, sealing a crawl space, retrofitting walls, or upgrading a garage, metal building, or new construction project, pricing depends on several factors including the size of your space, foam type (closed cell or open cell), accessibility, and the scope of work. At Savannah Spray Foam Insulation, we believe in transparent pricing and honest estimates so you know exactly what to expect.

| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Savannah attics bake through long, humid cooling seasons, and spray foam on the roof deck cuts heat gain fast. We seal top plates and penetrations, then insulate rafters under oak-shaded Ardsley Park rooftops and new builds toward Pooler. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Closed cell spray foam gives Savannah's humid crawl spaces and rim joists a rigid, moisture-blocking layer. We build up passes to the right thickness for rim joists and foundation walls under historic Savannah homes. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Open cell spray foam fills stud cavities in Savannah's new subdivision walls and quiets rooms over garages. We spray walls and ceilings in Pooler and Richmond Hill homes where sound and mild-winter comfort matter more than vapor control. |
| Wall & Injection Foam Insulation | From $2/sq ft | Wall injection foam fills hidden stud cavities in Savannah's century-old frame houses without opening the plaster. We drill small holes and inject foam into exterior walls across the Historic District and Ardsley Park. |
| Crawl Space Spray Foam Insulation | From $2,500 | Savannah's raised crawl spaces under older homes pull in damp coastal air that spray foam can seal out for good. We spray foam walls and encapsulate the space to stop moisture, cut musty odors, and keep ductwork drier under Ardsley Park and Pooler houses. |
| Rim Joist & Band Joist Spray Foam | From $650 | Rim and band joists in Savannah's raised crawl-space homes are common weak points for damp coastal air. We foam these gaps to block the drafts and humidity that older Savannah houses let in at the floor line. |
| Garage Spray Foam Insulation | From $1,200 | Garages in Pooler and Richmond Hill subdivisions bake through Savannah's long cooling season without insulation. We spray foam the ceiling and walls to cut heat transfer into rooms above and keep the space usable year round. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Metal buildings and warehouses across Chatham County sweat and rust without a foam layer blocking condensation. We spray foam directly to the metal panels and purlins to stop sweating and cut noise from summer storms. |
| Commercial & New Construction Spray Foam | Free commercial estimate | New construction across Chatham, Bryan and Effingham counties gets spray foam before drywall closes up the walls. We foam roof decks, walls and crawl spaces on new builds and commercial jobs before the next phase starts. |
| Insulation Removal | From $950 | Old insulation in Savannah attics and crawl spaces traps decades of coastal moisture and musty odors. We remove it cleanly from attics, walls and crawl spaces across Chatham County before new foam goes in. |
| Insulation Replacement & Re-Insulation | From $2,800 | Savannah homes with aging insulation lose the fight against humid coastal air long before summer ends. We pull the old material and spray or batt new insulation sized for Chatham, Bryan and Effingham county homes. |
| Air Sealing | From $650 | Hurricane season winds and year-round humidity push air through gaps in Savannah homes that spray foam can close. We seal top plates, penetrations and rim joists so conditioned air stays put through Savannah's long cooling season. |
What Affects the Price
- Square Footage and Project Size : Larger projects typically benefit from better per-unit pricing. Whether you're insulating 500 sq ft or 5,000 sq ft, the total area directly impacts your overall cost.
- Foam Type (Closed Cell vs. Open Cell) : Closed cell foam ($1.20/board ft) provides superior R-value and moisture resistance, while open cell foam ($0.55/board ft) is a budget-friendly option with excellent soundproofing properties.
- Accessibility and Site Conditions : Easy-to-reach attics cost less than cramped crawl spaces or complex roof decks. Existing insulation that needs removal, tight spaces, or structural obstacles may affect pricing.
- Project Type and Complexity : Simple attic insulation differs from wall injection foam retrofits, rim joist sealing, or commercial new construction. Each application has unique labor and material requirements.
