Insulation & crawl space cost questions
How much does attic insulation cost?
In the Charlotte area, attic insulation typically runs about $1,800 to $6,000 for most homes — roughly $2.40 to $4.20 per square foot for a top-up or new blown-in install. A full attic restoration (removing old insulation, air sealing, and re-insulating) runs higher, around $4.80 to $7.80 per square foot. Your exact price depends on the size of the attic, how much insulation is already there, and how easy it is to access.
What's the average cost of crawl space encapsulation?
Crawl space encapsulation in the Charlotte and Gaston County area generally runs about $5.50 to $9.50 per square foot, or roughly $5,000 to $15,000 for a typical crawl space. A full solution with insulation, a dehumidifier, and drainage runs $8 to $14 per square foot. The final number depends on crawl height, how much moisture is present, and whether drainage is needed.
How much does it cost to remove and replace attic insulation?
A full attic restoration — removing old or contaminated insulation, air sealing, and installing new insulation — typically runs about $4,000 to $12,000 in the Charlotte area, or $4.80 to $7.80 per square foot. Heavy contamination, moisture, or difficult access can raise the price.
Does new insulation or crawl space encapsulation pay for itself?
Most homeowners see lower heating and cooling bills — often in the 10–18% range after proper insulation and air sealing — plus fewer moisture and structural repairs down the road. In our humid climate, crawl space encapsulation is often one of the higher-return improvements a home can make.
