Quick answer: Spray foam insulation in Taylors costs $1.00–$1.60 per board foot for open-cell and $1.60–$2.60 per board foot for closed-cell. Full scopes are quoted per project after an on-site assessment. Most jobs finish in one day. Final pricing depends on crawl-space access, the foam thickness the assembly needs, and whether existing insulation has to be removed first — we give a firm number after we see the space.
Taylors Homeowners Are Paying Too Much to Heat Drafty Bungalows
Most older homes in Taylors weren’t built with Upstate SC winters in mind — the kind of cold that hits in January when temperatures drop into the twenties and your heating bill climbs past $300. Spray foam seals the gaps that fiberglass batts never will.
Taylors sits just north of Greenville along the Wade Hampton corridor, and a big chunk of its housing stock dates back to the 1950s, 60s, and 70s. Those bungalows and ranch-style homes were built fast, built cheap, and built with little thought for air sealing. The original insulation — if it’s still there — has settled, compressed, or grown moldy over the past fifty years. The result is cold floors in winter, high humidity in summer, and utility bills that keep climbing year over year.
What makes Taylors specifically rough is the crawl space problem. A large share of these older homes sit on pier-and-beam foundations, with vented crawl spaces that pull cold air straight up through the floor system. During an Upstate SC winter — when Greenville County regularly sees overnight lows in the upper twenties — that cold air migrates through every gap in the subfloor and into the living space above. No amount of thermostat adjustment makes up for a floor that’s open to outside air six inches below your feet.
Crawl Space Encapsulation with Closed-Cell Spray Foam
For Taylors homes with vented crawl spaces, closed-cell spray foam applied to the underside of the subfloor is the most effective fix available. It creates a continuous air barrier that stops cold infiltration in winter and humid outside air in summer. Closed-cell foam also adds structural rigidity to aging floor joists — a real benefit in homes that have been standing since Eisenhower was president.
Attic Air Sealing with Open-Cell Spray Foam
Older bungalows in Taylors typically have uninsulated or under-insulated attics with dozens of small penetrations — around light boxes, plumbing vents, and ceiling fans — where conditioned air leaks straight out. Open-cell spray foam fills those gaps completely and covers the attic deck or rafters in a single application. It’s the most cost-effective way to stop the stack effect that pulls warm air up and out of these homes all winter.
Rim Joist and Band Joist Sealing
The rim joist — the perimeter framing that sits on top of your foundation — is one of the most overlooked air leak points in Taylors homes. It’s typically uninsulated, exposed to outdoor temperatures, and riddled with gaps where the floor framing meets the foundation wall. A few inches of closed-cell spray foam on the rim joist pays back quickly in reduced heating and cooling costs and is usually done in a single afternoon.
Spray foam pricing in the Taylors SC area runs:
- Open-cell foam: $1.00–$1.60 per board foot (never mix with per-square-foot without stating thickness)
- Closed-cell foam: $1.60–$2.60 per board foot (never mix with per-square-foot without stating thickness)
Statewide reported averages for installed spray foam in South Carolina (from contractor-reported data) range from statewide reported averages, with final square-foot cost depending on foam thickness, with an average of $1.87 (source: ProMatcher South Carolina insulation cost report, insulation.promatcher.com/cost/south-carolina.aspx, pulled 2026-07-10). These figures should be interpreted with a thickness caveat — they are not our own quotes.
For a typical Taylors bungalow with a 1,000-square-foot crawl space and attic air sealing, most homeowners are looking at a total project in the $2,500–$5,000 range depending on access, current insulation condition, and which areas get treated. Crawl space work alone on a smaller home can fall under $1,500. Jobs are priced after a visual assessment — there’s no guessing from square footage alone.

Spray Foam for Taylors and Travelers Rest Homeowners: What North Greenville County Builds Need
Every winter, homeowners in Taylors notice the same thing: their Duke Energy bill climbs while the house still feels drafty in every room that faces the ridge. In Travelers Rest, the problem often runs the opposite direction — a cottage or newer mountain-access home that felt snug when it was built starts showing its seams after a few Upstate winters, and comfort becomes something you negotiate with your thermostat.
North Greenville County sits in its own micro-climate. Paris Mountain and the first folds of the Blue Ridge foothills push overnight lows a few degrees cooler than downtown Greenville, and that gap matters more than most homeowners expect. The insulation strategy that works on a flat tract home in Mauldin does not automatically translate to a 1960s mill-era house in Taylors or a hillside cottage off Highway 25.
Travelers Rest is a different situation. Much of the newer residential development along the northern corridors — the areas pushing toward Slater-Marietta and the Swamp Rabbit Trail's upper reaches — consists of cottages, spec homes, and custom builds that were constructed in the last fifteen to twenty years. These homes were built to code, but code minimum is not the same as performance.
For newer Travelers Rest builds, spray foam most often makes sense in three locations: the bonus room or conditioned upper space, the garage ceiling if living space sits above it, and any vaulted or cathedral ceiling assembly where blown insulation has settled or where the original design left insufficient rafter depth. Open-cell foam in these cavities fills completely, conforms to irregular framing, and eliminates the air movement that pulls conditioned air out of those spaces.
The decision between open-cell and closed-cell is not always obvious, and the right answer depends on where in the assembly the foam is being applied, what the existing moisture conditions are, and what the long-term goals for that space are. A crawl space in a 1955 Taylors home calls for a different approach than a vaulted ceiling in a Travelers Rest cottage built in 2009.
If you are a Taylors homeowner who has been patching around the same draft for years, or a Travelers Rest homeowner who bought a newer home and still can't get the upstairs comfortable in January, spray foam is worth an honest conversation with a contractor who knows the Upstate market and the specific demands of north Greenville County construction.
