Port Wentworth's newer slab-built subdivisions and industrial warehouse space near the river face a year-round moisture challenge that older Savannah neighborhoods don't: hot, humid air pushing inward through every wall and attic all summer long, and no crawl space to buffer the foundation from the damp.
Savannah Spray Foam Insulation has served Port Wentworth and the surrounding Savannah area since 2010. We know the difference between a tight, conditioned attic and a vented one that bakes in the summer heat and pulls coastal humidity through every gap. Our team handles the insulation and air sealing work that keeps your energy bills honest and your rooms at temperature, whether you're in a new subdivision near I-95 or managing commercial space closer to the river.
Spray Foam Insulation in Port Wentworth (31407)
Port Wentworth's housing stock splits into two distinct challenges. The newer subdivisions use slab-on-grade foundations with stick-framed walls and vented attics carrying ductwork. That ductwork runs through unconditioned space in the summer, losing cool air to the heat and humidity outside. The attics themselves bake under the sun for months on end, and any gap in the insulation or air seal means your cooling system works overtime. Rooms over garages and at the end of a duct run are the first to fall out of temperature.
The industrial and warehouse properties near the river face similar moisture pressure from a different angle. Slab foundations with exposed perimeter and metal building shells need a tight thermal and moisture barrier to keep the space usable and to protect stored goods from condensation and humidity swings. Port Wentworth's climate, with hot summers and high dew points year-round, means moisture is the dominant failure mode, not winter cold.
We've been sealing and insulating attics, walls, rim joists, and metal buildings across the Savannah area since 2010. We understand the local building stock, the code requirements that apply at your address in Port Wentworth, and the difference between a quick spray and a job that stays tight.

How a Job Works in Port Wentworth
We start with a free on-site assessment. We walk your attic, crawl space, or the walls you want sealed. We measure the area, look at what's there now, check for moisture or damage that has to be addressed before any foam goes in, and talk through open cell versus closed cell and what R-value makes sense for your space and your budget. We give you a written estimate with R-value and thickness specs so you know exactly what you're paying for.
On the day of the work, our fully insured crew sets up mechanical ventilation to manage the air during application and cure. We spray the foam to the thickness and coverage specified in your estimate. If existing insulation has to come out first (wet batts, contaminated material, or insulation blocking the space we need), we remove it and haul it away. We seal gaps and rim joists and any other air leaks we identify. The work typically takes a day or less, depending on the area and what's already there.
After we finish, we clean up the site and walk through the work with you. We give you a re-entry window of twenty-four to forty-eight hours before you occupy the space fully, and we explain what to expect during the cure period. You're left with a tight, conditioned space and a property that's easier to heat and cool.
Pricing for spray foam insulation in Port Wentworth depends on the area you're covering, the R-value you need, whether you're using open cell or closed cell foam, and what has to be removed or prepped first. Attic foam typically runs from $1.50 per square foot for open cell work up to $1.20 per board foot for closed cell, depending on thickness and density. Wall injection foam starts at $2 per square foot. A crawl space air seal and foam job usually runs from $2,500 and up. If you have old, wet, or contaminated insulation that has to come out first, add $950 and up for removal. Every job is different, and the only way to know your actual cost is a site visit and a written estimate.
