They came out within two days of my call and finished the attic the same morning. My upstairs bedroom was already noticeably cooler by that evening. Exactly what I needed before summer hit.
Marcus T., Goose Creek, SC - Attic insulation
We had a musty smell in our crawl space for two summers. After the spray foam and vapor barrier work, it was gone within a week. The crew was clean, on time, and explained everything they were doing.
Sandra W., North Charleston, SC - Crawl space insulation
I got three quotes and Hanahan Insulation was the only one who actually came out and looked before giving me a number. The estimate was detailed and the price came in under what the other two quoted over the phone.

Attic temperatures in the South Carolina Lowcountry can exceed 130 degrees on a summer afternoon. That heat pushes straight down through a thin or missing insulation layer, forcing your air conditioner to work harder than it should. The U.S. Department of Energy recommends attic insulation rated between R-38 and R-60 for homes in this climate zone.
In a coastal climate like Hanahan's, warm humid air constantly presses against your home's shell. When it finds a gap - around pipes, fixtures, or a thin crawl space - it carries moisture inside and creates conditions where mold and wood rot can develop quietly. Proper insulation and air sealing cut off those pathways before damage starts.
Closed-cell spray foam is denser, provides higher R-value per inch, and resists moisture - making it the better choice for crawl spaces and exterior walls in humid climates. Open-cell foam is softer and less expensive, which makes it a practical option for interior walls and attics where moisture is less of a concern. Your contractor should explain the difference.
For most Hanahan homeowners, yes. Air sealing and insulation together can reduce energy bills by a meaningful amount, according to the U.S. Department of Energy. In a place where air conditioning runs hard from May through September, even a moderate improvement in your home's envelope adds up to real savings over time.
Homes built before the mid-1990s were often insulated to a much lower standard than what is recommended today - and that standard did not account for the moisture load that comes with a Lowcountry climate. If your home is more than 25 years old and has never had insulation work done, a free assessment will tell you exactly where the gaps are.
Air sealing closes the small gaps around light fixtures, pipes, and penetrations in your attic floor or walls where air moves freely. Without this step, even thick insulation underperforms because conditioned air is still escaping and hot outdoor air is still getting in. According to the{' '} U.S. Department of Energy, air sealing is often the single most impactful step a homeowner can take before adding new insulation.

If your existing insulation has been wet, has visible mold, or shows signs of pest activity, adding new material on top will not solve the problem. Removal and replacement is the right path forward, and a good contractor will tell you honestly whether you are in that situation.
The clearest signs are visible floor joists when you look into the attic, rooms that are significantly hotter in summer than the rest of the house, and energy bills that keep climbing. A contractor can measure what you have during a free assessment.
At minimum, it should list the area being insulated, the type of material, the depth or coverage being installed, whether air sealing is included, and the total price. If any of those items are missing, ask before you sign.
The ENERGY STAR Home Sealing program offers a homeowner checklist that walks you through identifying common insulation and air-sealing problems. When you are ready to act on what you find, call (843) 543-6405 and we will schedule a free on-site estimate.
Hanahan is a city of roughly 27,000 people in Berkeley County, sitting just north of North Charleston and about 15 miles from downtown Charleston, SC. Most of the city's housing stock dates from the 1970s through the early 2000s - homes in Tanner Plantation, near the Hanahan Recreation Complex, and in older subdivisions near Otranto Road. Homes in this age range are prime candidates for insulation upgrades, since the standards in place when they were built fall well short of what is recommended for this climate today.
The combination of hot, humid summers and the proximity to coastal waterways creates real insulation challenges here. Ground moisture levels are consistently high, and many homes sit on vented crawl spaces that let that moisture push up into the living space. Families stationed nearby at Joint Base Charleston often face deferred maintenance from years of tenant use - and a crawl space or attic that has not been inspected in years can quietly develop moisture and mold problems.
Hanahan Insulation is based in Hanahan and has been working on homes here since 2020. We know which neighborhoods have older stock, which crawl spaces are most vulnerable to moisture, and what it takes to keep a Lowcountry home comfortable through a South Carolina summer. If your home is more than 20 years old, a free assessment will tell you exactly where you stand.
