"They came out, looked at my crawl space, and gave me a written estimate the same week. Job was done in one day. My floors don't feel cold and damp anymore, and my electric bill dropped noticeably the next month."
"My upstairs bedrooms were miserable every summer. After they added blown-in to the attic and sealed the gaps around the light fixtures, the whole second floor finally feels like it belongs to the same house."
"I was skeptical spray foam was worth the cost. They walked me through what they were doing and why. Two months later I can say my air conditioner runs about half as often. I wish I had done this five years ago."

If your upstairs rooms are noticeably hotter than downstairs in summer, or if you can see the wooden joists across your attic floor, your insulation is almost certainly too thin. The U.S. Department of Energy recommends an R-38 to R-60 rating for attics in South Carolina - many older homes have half that.
Moisture is insulation's enemy. When fiberglass batts absorb humidity - common in Florence's climate - they lose most of their ability to slow heat transfer. Closed-cell spray foam is the exception: it resists moisture instead of absorbing it, which is why it is the preferred choice for crawl spaces here.
Insulation slows heat from moving through surfaces. Air sealing stops drafts from sneaking around insulation through gaps around pipes, outlets, and light fixtures. Skipping air sealing is the most common reason a homeowner does not feel a difference after adding insulation - the heat finds another way in.
Open-cell foam is softer and better for interior walls and attics where sound control matters. Closed-cell foam is denser and also acts as a moisture barrier. For any area where moisture from the ground or exterior is a concern - crawl spaces, rim joists, exterior walls - closed-cell is the right call in South Carolina. See the{' '}U.S. Department of Energy guide to insulation types for a full comparison.
Wet insulation looks dark, clumped, or matted rather than fluffy and even. If your home had water intrusion from a hurricane or tropical storm, the insulation in the affected area may have absorbed moisture and lost most of its effectiveness - even after it appears dry. It should be inspected and likely replaced.
Yes. Blown-in insulation is specifically designed for this situation - a contractor drills small holes in the wall cavity, fills it completely using a hose, and patches the holes. Spray foam can be applied to exposed surfaces in attics and crawl spaces without any demolition. Most retrofit jobs are done in a day.

The most common reason is that air sealing was skipped. Insulation slows heat through surfaces - air sealing stops it from sneaking around through gaps. If your contractor did not seal around light fixtures, pipes, and outlets before installing, heat is still finding its way in.
Musty smells on the first floor, soft or springy spots in flooring, higher indoor humidity, and visible moisture under the house are all signs your crawl space is not properly sealed. Florence's flat land and clay soil mean water drains slowly, and crawl spaces take the hit first.
Usually yes. Buyers and inspectors look at the attic, and an under-insulated attic can become a negotiating point at closing. A properly insulated and documented attic is an asset you can point to with confidence - and it makes the home more comfortable for whoever lives there in the meantime.
The ENERGY STAR Seal and Insulate program estimates homeowners can save up to 15% on heating and cooling costs with proper insulation and air sealing - a meaningful number in Florence where cooling season runs from April through October.

Florence is the largest city in the Pee Dee region of northeastern South Carolina, with a population of roughly 38,000 inside city limits and about 140,000 in Florence County. The city sits where I-95 and I-20 meet, and it serves as a regional hub for commerce, healthcare, and education. Major institutions like McLeod Regional Medical Center and Francis Marion University bring workers and families to the area year-round.
The bulk of Florence housing was built between the 1950s and 1980s in established neighborhoods like Brierfield, Timrod Park, and West Florence - brick ranch homes on generous lots with mature oak and pine trees. Newer subdivisions along Hoffmeyer Road and the South Florence corridor are also part of the city. Older homes in this area were built well before modern insulation standards, and Florence's climate - hot, humid summers with average July highs near 92 degrees and heavy annual rainfall around 46 to 48 inches - puts real pressure on attics and crawl spaces every year. The Florence Civic Center anchors the downtown, and the city has invested in revitalization along Palmetto Street and the surrounding blocks.
Florence gets nearly four feet of rain a year, and with flat terrain and clay soil, that water drains slowly - which is why wet crawl spaces and drainage problems around foundations are so common here. Hurricane Florence in 2018 was a reminder of how much moisture a single storm can push into homes that are not properly protected. If your home is in Florence or a surrounding community and has never had its insulation assessed, it is worth a conversation - especially if the house was built before 1990.
