Commercial & New Construction Spray Foam Savannah

Commercial & New Construction Spray Foam in Savannah insulates new builds and commercial projects across Chatham, Bryan and Effingham counties before drywall closes the walls and mechanical systems go in. New construction in the Lowcountry runs year-round, and builders here know that spray foam on roof decks, walls and crawl spaces before the next phase locks in the thermal envelope and controls moisture from day one. Whether you are framing a subdivision pushing toward Pooler and Richmond Hill, closing up a commercial shell in Garden City, or insulating crawl spaces and band joists on new stick-framed homes in Savannah proper, the window is narrow and the installation must be right the first time. We spray closed cell and open cell foam on new construction projects, seal all penetrations and air barriers, and move fast so your schedule stays on track.

Why New Construction Spray Foam Matters in Savannah's Building Boom

New residential and commercial construction across Greater Savannah has accelerated into Bryan and Effingham counties, and builders are waking up to moisture control. Savannah sits in climate zone 2A with hot, humid summers and mild winters, which means moisture-driven inward pressure through walls and foundations most of the year. Vented attics and open crawl spaces on new builds pull in damp coastal air off the Savannah River, and that humidity loads the structure before occupancy. Spray foam on roof decks and in crawl spaces stops that infiltration before it starts, and the air seal around it keeps conditioned air from leaking into unconditioned space.

We spray closed cell foam on roof decks to create a sealed, conditioned attic that keeps summer heat and humidity out of the living space.
We foam crawl space walls and band joists on new construction to stop moisture ingress and protect rim board and floor framing from the ground up.
We seal all wall penetrations and rim transitions so the air barrier is complete before drywall closes the cavity.
We work to the builder's schedule and coordinate with framing, electrical and HVAC so your project flow is not disrupted.

Builders who spray foam new construction in Savannah report tighter homes, lower call-back rates for comfort complaints, and faster drying times after the wet trades finish.

Key info: New construction spray foam is installed before drywall, electrical trim-out and HVAC rough-in, which means the job must be scheduled tight with the framing crew. Permits and thermal barrier requirements vary by city across Savannah, Pooler, Richmond Hill and Garden City, so your local building department can tell you what applies at your address and defer to the local building department.

How We Install Commercial & New Construction Spray Foam in Savannah

New construction spray foam is a precision job because the substrate is clean, the schedule is tight, and the installer must stay coordinated with the builder's framing and mechanical trades. We start with a site walk-through to confirm roof deck dimensions, crawl space access, wall cavity depth and any electrical or plumbing rough-in that affects spray zones. We then schedule the foam application after framing is complete but before drywall, HVAC ductwork or electrical trim-out begins. Once the foam cures, we verify thickness and R-value against the specifications in the estimate, and the builder moves to the next phase.

We inspect the framing and substrate to confirm it is clean, dry and ready for foam.
We set up mechanical ventilation and establish a re-entry perimeter so the building can remain unoccupied during the cure window.
We spray foam to the specified thickness in controlled passes, holding the manufacturer ratio and drum temperature throughout.
We allow the foam to cure for twenty-four to forty-eight hours before drywall, HVAC or electrical work resumes.
We photograph the installation and provide the builder with R-value and thickness documentation for the permit file.

This step-by-step approach means no surprises on the job site and no delays to the builder's schedule.

Example: A new 12-unit townhome development in Richmond Hill requires closed cell foam on the roof deck and open cell foam in the crawl space to meet the energy code. We schedule the spray after framing, before drywall. The job takes two days, the foam cures overnight, and the builder's drywall crew starts the next morning on schedule.

Commercial & New Construction Spray Foam Methods and Approaches

Approach	Description	Best For
Closed Cell Roof Deck	High-density foam sprayed 1.5 to 2 inches thick on the underside of the roof sheathing to create a conditioned, sealed attic.	New construction in hot, humid climates where moisture control and air sealing are priority.
Open Cell Crawl Space	Low-density foam sprayed 3.5 to 4 inches on crawl space walls and rim joists to insulate and air-seal without vapor barrier.	New construction in moderate climates where vapor permeability is acceptable and cost is a factor.
Closed Cell Wall Cavity	High-density foam sprayed 1.5 to 2 inches in wall cavities before drywall to seal all penetrations and air leaks.	New stick-framed residential and light commercial construction where air sealing and moisture control are required.
Commercial Metal Building	Closed cell foam sprayed on the underside of metal roof and wall panels to prevent condensation and insulate the shell.	New commercial shells, warehouses and agricultural buildings where condensation on steel is the dominant failure mode.

Each method is chosen based on the building type, the local climate and the builder's energy code compliance target.

Commercial & New Construction Spray Foam Cost in Savannah: What to Expect

New construction spray foam is priced by the board foot installed, which means the cost depends on the roof deck area, crawl space square footage, wall cavity volume and the foam type (closed cell or open cell). A typical new residential project in Savannah or Pooler runs from a few hundred board feet on a small townhome to several thousand on a full-size subdivision lot. Commercial jobs vary widely depending on the building footprint and the scope of sealing. The best starting point is a free commercial estimate on site, where we measure the space, confirm the substrate and building code, and give you a fixed price with R-value and thickness spelled out.

Several factors move the cost up or down. Roof deck area is the primary driver: a 1,500-square-foot sealed attic on a single-story home is a smaller job than a two-story colonial with dormers and a complex roof line. Crawl space depth and access affect the spray setup and labor time. Wall cavity fill depends on whether the foam is going into new open framing or being injected into existing cavities. Proximity to utilities, occupied spaces or sensitive equipment may require additional ventilation or containment. We always provide a detailed estimate with the thickness in inches, the R-value per inch, and the total board feet and cost, so you know exactly what you are paying for.

Hiring a Commercial & New Construction Spray Foam Contractor Near Me in Savannah

Finding the right spray foam contractor for your new construction project means verifying that the installer has insurance, understands the local building code, and can deliver on time and on spec. Start by asking any contractor for proof of full insurance coverage and a certificate of insurance naming your project. Request at least two or three estimates so you can compare the R-value, thickness, board feet and price across contractors. Ask the contractor about their experience with new construction in your city or county, and ask to see examples of sealed attics or crawl spaces they have completed. Check that they understand the thermal barrier and ignition barrier rules in your local building code, because that distinction is where many generalists stumble. If your project is in an HOA or master-planned community, confirm that the contractor knows the architectural guidelines for any exterior or mechanical work.

Verify that the contractor carries full insurance and can provide a certificate of insurance before work begins.
Ask for multiple written estimates that spell out R-value, thickness in inches and total board feet so you can compare apples to apples.
Request references from recent new construction projects in Savannah, Pooler or Richmond Hill so you can ask about their experience and schedule reliability.
Confirm that the contractor understands the local building code at your address and defers to the building department on permits and thermal barriers.
Ask about the cure time and re-entry window so you know when your drywall or mechanical crew can resume work.

A contractor who provides a detailed estimate with no surprises and coordinates cleanly with your builder's schedule is worth the call.

Frequently asked questions: Commercial & New Construction Spray Foam in Savannah

How much does commercial and new construction spray foam cost in Savannah?

New construction spray foam is priced by the board foot installed, typically ranging from $0.55 to $0.65 per board foot depending on foam type, thickness and project scope. A residential new build with a sealed attic and crawl space might run $2,500 to $5,000 total. Commercial buildings and larger projects are estimated on site. The best way to get an accurate price is a free commercial estimate where we measure your project and provide a fixed quote with R-value and thickness specified.

When should spray foam be installed during new construction in Savannah?

Spray foam is installed after framing is complete but before drywall, electrical trim-out or HVAC ductwork. This timing protects the foam from damage, allows proper curing before the next trade moves in, and ensures the air seal is complete before the building closes up. We coordinate with your builder's schedule so the job stays on track and there are no delays to the drywall crew or mechanical contractors.

What is the difference between closed cell and open cell foam for new construction?

Closed cell foam is high-density (1.5 to 2 inches thick), provides an R-value of 6 to 7 per inch, and acts as an air and vapor barrier. It is ideal for roof decks and crawl spaces where moisture control is critical. Open cell foam is low-density (3.5 to 4 inches thick), provides an R-value of 3.5 to 4 per inch, and is vapor-permeable. It costs less and is often used in crawl spaces and walls where vapor permeability is acceptable. For new construction in Savannah's hot, humid climate, closed cell on the roof deck is the standard choice.

How long does it take to spray foam a new construction project in Savannah?

Installation time depends on the square footage and complexity. A typical residential project with roof deck and crawl space takes one to two days. The foam then requires twenty-four to forty-eight hours to cure before drywall or mechanical work resumes. We schedule the work to fit your builder's timeline and coordinate with the framing, electrical and HVAC trades so there are no conflicts or delays.

Do I need a permit for spray foam insulation on new construction in Savannah?

Permit requirements vary by city and county across Greater Savannah. New construction projects typically require energy code compliance documentation, and spray foam installation must be inspected and approved by the local building department. We help you understand what applies at your address and provide the R-value and thickness documentation needed for the permit file. Always defer to your local building department for the final word on permits and thermal barrier requirements.

Does spray foam stop air leakage in new construction?

Yes. Spray foam expands to fill cavities and adheres to the substrate, creating a continuous air seal. This stops infiltration through walls, roof decks and crawl spaces, which is why it is so effective for new construction. The air seal also improves the performance of your HVAC system because conditioned air stays inside and unconditioned air stays out. In Savannah's hot, humid climate, a tight air seal is critical to controlling moisture and keeping cooling loads down.

What is the best time of year for new construction spray foam in Savannah?

New construction spray foam can be installed year-round in Savannah, but spring through early fall is the busiest season because the building season peaks then. Residential and commercial projects move fastest when framing is complete and the weather is dry. Winter is quieter but still productive. The key is coordinating the foam spray with your builder's framing and drywall schedule, not the season. We work around your timeline and the weather to keep the job on track.

Is spray foam safe to install in new construction?

Spray foam is safe when installed correctly by a trained contractor. The key is proper application, controlled thickness per pass, correct manufacturer ratio and drum temperature, and mechanical ventilation during the cure window. We require a re-entry wait of twenty-four to forty-eight hours after spraying so the foam can cure fully before occupants or other trades enter the space. Once cured, spray foam is inert and meets building code. We never promise immediate re-entry or skip ventilation, because that is how problems start.

Can spray foam be installed over wet or damaged substrate in new construction?

No. We inspect the substrate before spraying and will not apply foam to wet, contaminated or damaged framing. If the substrate is not ready, we stop and recommend fixing the issue first. This is not a caveat, it is a selling point. A sound substrate means the foam bonds properly, cures correctly and performs as designed. If there is standing water, active leaks or structural damage, we walk away and refer you to the right specialist to fix the root cause first.
