Summerville Insulation is an insulation contractor serving Conway, SC with home insulation, crawl space vapor barriers, and spray foam insulation services - we have completed jobs on wood-frame and vinyl homes throughout Horry County, with free estimates and responses within one business day.
A large share of Conway homes were built between the 1970s and 1990s, and those properties are hitting the age when insulation in the attic and crawl space has settled, absorbed moisture, or simply worn out. Conway gets about 50 inches of rain per year, and the flat coastal plain terrain means that moisture works on homes from the ground up as well as through the attic. See the full breakdown of what a home insulation assessment and installation covers and what it means for energy costs in a Conway home.
Conway sits on flat, sandy coastal plain soil that holds water after rain and stays moist through humid summers. Homes built on crawl space foundations here - especially those built before 1995 without a vapor barrier - have ground moisture moving up into their floor framing continuously. A properly installed vapor barrier covering the full crawl space floor and walls is the first and most important defense against the mold, wood rot, and structural damage that this environment produces over time.
Conway is about 15 miles from the South Carolina coast, and the coastal climate means hot, humid air sits over the area from May through September with no real relief. An attic in a Conway home built in the 1970s or 1980s with original insulation is holding far less R-value than is now recommended for this climate zone. Upgrading attic insulation is typically the single highest-return step a Conway homeowner can take to reduce summer cooling costs.
For Conway crawl spaces with persistent moisture problems - particularly on lots near the Waccamaw River or in low-lying areas prone to standing water - closed-cell spray foam on crawl space walls and rim joists is the most durable option available. It does not absorb water, does not sag, and holds its insulating value even when the crawl space environment is wet. For those specific problem spots, no other material performs comparably in this climate.
For Conway homes with accessible attic space, blown-in loose-fill insulation brings the attic up to the R-38 to R-60 range recommended for this coastal climate without disturbing the rooms below. It is well-suited to the older construction in Conway neighborhoods like those near Coastal Carolina University, where attics often have irregular framing and narrow access hatches that make batt installation difficult or impossible without removing drywall.
Conway homes built on crawl space foundations face a demanding moisture environment year-round. The combination of flat soil, coastal humidity, and frequent heavy rain means that any crawl space without proper insulation and moisture management is actively working against your floor framing and indoor air quality. Proper crawl space insulation, paired with a vapor barrier and any needed drainage corrections, stops that process before it becomes a structural problem.
Conway is the county seat of Horry County and sits about 15 miles inland from Myrtle Beach, with a population of about 25,000 and a housing stock built primarily between the 1970s and the 1990s. That era of construction used vinyl siding, asphalt shingles, and insulation standards that have since been surpassed by current energy code recommendations. These homes are now 30 to 50 years old - right at the age when attic insulation has settled to well below effective levels, vapor barriers are absent or degraded, and HVAC systems are running harder than they should to compensate. The city sits on flat coastal plain terrain with sandy and clay soils that hold water. Conway receives about 50 inches of rain per year, and low-lying lots near the Waccamaw River or in neighborhoods with poor drainage can stay wet for extended periods after heavy storms. Homes built before the mid-1990s on crawl space foundations here typically have little or no ground moisture protection.
The coastal location adds another dimension. Conway is close enough to the Grand Strand that it sits in the direct path of hurricanes and tropical storms that make landfall along the South Carolina coast. Hurricane Florence in 2018 caused serious flooding in Conway, particularly near the Waccamaw River. Even storms that weaken before reaching Conway can bring days of heavy rain, elevated humidity, and wind-driven moisture that penetrates any gap in a home's thermal envelope. A properly sealed and insulated home recovers faster from those events and is less likely to develop mold or moisture damage in the weeks that follow. Insulation work in Conway is not just about energy bills - it is about protecting a home that faces real environmental pressure every hurricane season.
When insulation work in Conway requires a permit, we pull it through the City of Conway Building Department. We know which project types in this jurisdiction trigger permit requirements and handle the paperwork on your behalf, so that is never something you have to sort out on your own.
Conway is anchored by Coastal Carolina University, a campus of more than 10,000 students on the east side of the city, and by the Conway Riverwalk, a popular boardwalk along the Waccamaw River in downtown. The homes we work on here span from the older wood-frame properties in the Conway Historic District, some dating to the late 1800s, to the vinyl-sided homes from the 1970s and 1980s that fill most of the residential areas, to newer subdivisions off Highway 501 built in the 2000s and 2010s. Older historic homes and newer suburban houses need different approaches, and we work on both.
We also serve the areas around Conway. If you are in Summerville to the west or in Florence to the northwest, the same crew covers your area with the same response time and no added travel fees.
Reach us by phone or through the contact form and we will respond within one business day. A few quick questions about your home - its age, whether it has a crawl space or slab, and what you have noticed - help us arrive prepared for what we are likely to find on a Conway property of that era.
We visit your home, inspect the attic, crawl space, and any areas of concern, and give you a written estimate at no charge. For Conway homes, we pay close attention to the ground moisture situation in the crawl space and the current depth and condition of any attic insulation - both are commonly deficient in homes from the 1970s and 1980s. No obligation and no fee for the visit.
We confirm the full scope and timing the day before the job. Attic insulation jobs in Conway are typically done in a single day. Crawl space jobs that include vapor barrier installation, old material removal, and new insulation or spray foam generally run one to two days. If spray foam is applied, plan to stay out of the treated area for at least 24 hours while it cures.
When the work is complete, we walk you through what was installed and where. If the project requires a permit inspection from the City of Conway, we schedule it and ensure the paperwork is properly closed before we consider the job finished.
We serve homeowners throughout Conway, SC - from the historic district near downtown and the Riverwalk to the newer neighborhoods off Highway 501. Free estimate, no obligation, response within one business day.
(854) 888-4697Conway is the county seat of Horry County and sits about 15 miles inland from Myrtle Beach, with a population of around 25,000. The Waccamaw River runs through the heart of the city, and the Conway Riverwalk along its banks is one of the most visited spots in the area - a boardwalk where locals walk, fish, and gather for community events. Downtown Conway has a well-preserved historic district with older wood-frame homes dating back to the late 1800s and early 1900s, and the city is home to Coastal Carolina University, which enrolls more than 10,000 students and is one of the largest employers in Horry County. The mix of an active university, a growing population, and proximity to the Grand Strand keeps Conway busy and keeps its housing market active year-round.
According to U.S. Census data, about 67% of Horry County homes are owner-occupied, reflecting a community of homeowners who are invested in keeping their properties in good shape. A large share of Conway housing was built between the 1970s and the 1990s, with newer subdivisions filling in along Highway 501 and the outer edges of the city since the 2000s. We serve homeowners across all of these neighborhoods, and we also cover Summerville to the west and Florence to the northwest, both of which share the coastal plain climate and moisture management challenges that define this part of South Carolina.
