Sumter Insulation serves Conway, SC with home insulation, crawl space insulation, and attic insulation - SC-licensed and experienced with the flat coastal plain terrain, high rainfall, and aging housing stock that Horry County homeowners deal with every year.
Conway homes built between the 1970s and 1990s are now hitting the age where insulation systems throughout the house - attic, walls, and crawl space - need to be assessed and often upgraded. Our home insulation service looks at the whole house, not just one area, and identifies where your home is losing the most energy for your specific floor plan and foundation type.
Most Conway homes are built on crawl space foundations, and the flat, wet terrain of Horry County means moisture collects under homes after every significant rain. Insulating and sealing the crawl space breaks the cycle of moisture intrusion that causes floor rot, mold, and high energy bills in coastal plain homes.
Conway's summer heat and humidity are hard on attic spaces, and homes from the 1970s and 1980s frequently have original insulation that has compressed and thinned over decades of thermal cycling. Bringing attic insulation up to the current recommended R-value for Horry County reduces the load on your air conditioner through the long cooling season.
Conway receives about 50 inches of rain per year, and after heavy summer storms or a tropical event, the ground under a crawl space can stay wet for days. A heavy-duty vapor barrier on the crawl space floor prevents that ground moisture from evaporating into the wood structure above - a specific concern in homes close to the Waccamaw River and other low-lying areas of the city.
Spray foam applied to crawl space walls and rim joists provides both insulation and a moisture barrier in one pass - a practical combination for Conway homes where humidity and ground moisture are both persistent problems. Closed-cell spray foam also adds structural rigidity to rim joists, which can be beneficial in homes that have experienced settling on flat coastal plain lots.
Blown-in insulation is a cost-effective way to top up attic coverage in Conway homes where the existing material has settled or been disturbed by pests. It fills irregular cavities more completely than batt insulation, making it well-suited to the older wood-frame homes in Conway's historic downtown neighborhoods and the varied attic configurations common in 1970s and 1980s ranch-style houses.
Conway sits in the South Carolina coastal plain about 15 miles inland from Myrtle Beach, in terrain that is almost completely flat with a mix of sandy and clay-heavy soils. That combination - flat ground, high rainfall around 50 inches per year, and soil that holds moisture - creates drainage conditions that directly affect homes. Water does not move away from foundations quickly here, and crawl spaces in Horry County deal with more persistent ground moisture than homes on higher or better-draining terrain. The city also sits along the Waccamaw River, and flooding near the river has historically affected older neighborhoods and downtown properties during tropical storms and major rain events.
A large share of Conway's housing stock was built between the 1970s and the 1990s - homes that are now 30 to 50 years old and approaching the age when roofs, insulation, and HVAC systems need to be replaced or significantly upgraded. These homes were built to standards well below what is currently recommended for South Carolina's coastal climate, and many have never had their insulation systems assessed. Conway also has a distinct older core near downtown and the Riverwalk, where wood-frame homes from the early 1900s are still occupied and in need of careful, knowledgeable work. Closer to Coastal Carolina University, a mix of rental properties and owner-occupied homes means some properties carry deferred maintenance that catches up all at once.
We regularly work on homes throughout Horry County, including the mix of older wood-frame houses in Conway proper and the newer subdivisions that have grown up along Highway 501 and in the communities between Conway and the Grand Strand. The crawl space moisture problems we see in Conway are consistent - flat lots, wet soil after rain, and homes that were built without vapor barriers or with barriers that have since degraded.
Conway is its own place, distinct from Myrtle Beach even though the two are close. The Conway Riverwalk along the Waccamaw River is a center of community life in the city, and the Historic District downtown includes some of the oldest homes we work on in Horry County. We know the difference between working on a 1910 wood-frame home near the river and a 1985 ranch on a flat lot off 501, and we adjust our approach accordingly.
We also serve homeowners in nearby Myrtle Beach, where the coastal conditions and salt air add another layer of consideration to insulation and moisture work. If you are anywhere between downtown Conway and the beaches along the Grand Strand, we cover your area.
We ask a few basic questions - what you have been noticing, how old the home is, and what area concerns you most. We respond within 1 business day and can generally schedule an on-site visit within a few days.
A technician inspects the crawl space, attic, or other area you are concerned about, checks for moisture damage or insulation deficiencies, and provides a written estimate before any work is scheduled. If the crawl space has moisture damage or existing material that needs to come out, we tell you that upfront rather than after we have already started.
Most Conway jobs are completed in a single day. Spray foam installations require you to stay out of the treated area for a few hours while the foam cures, and we give you that re-entry window before we begin. Larger jobs that include old material removal may take two days.
Before we pack up, we walk you through the work so you can see exactly what was done. If anything looks off or you have questions, we address them before we go - not over the phone a week later.
We serve homeowners throughout Conway and Horry County. Call or submit a request and we will respond within 1 business day with an honest assessment of what your home needs.
(803) 859-8329Conway is the county seat of Horry County and one of the older cities on South Carolina's coastal plain, with a population of around 25,000 people. The city sits along the Waccamaw River, and its historic downtown - listed on the National Register of Historic Places - includes well-preserved early 20th-century commercial buildings and wood-frame homes that give the area a distinct character. Coastal Carolina University, with more than 10,000 students, is located in Conway and is one of the city's major employers and economic anchors. The university campus brings a mix of long-term residents and a rotating student population that shapes the rental market in parts of the city, particularly near campus.
Conway has grown steadily over the past two decades, partly because it offers more affordable housing than nearby Myrtle Beach and partly because Horry County overall has been one of South Carolina's fastest-growing counties. New subdivisions along Highway 501 and in the communities between Conway and the Grand Strand have brought a range of newer single-family homes to the area. These homes sit alongside an older in-town core where many properties were built between the 1970s and 1990s - now at the age when systems need to be upgraded rather than just repaired. We also serve homeowners in nearby Florence, another Pee Dee region city with similar coastal plain conditions and a comparable mix of housing ages and types.
