What Charlotte Homeowners Are Saying
Real results from real customers across the Charlotte metro area.
"Our energy bills dropped by almost $180 a month after Charlotte Expert spray foamed our attic. The crew was professional, on time, and cleaned up completely. Highly recommend."
"We had another company spray foam our crawl space years ago and it was done wrong. Charlotte Expert came in, explained exactly what the previous contractor did badly, and fixed it properly. Night and day difference."
"Used them for our new construction build. The closed cell foam on the roof deck was exactly what I wanted -- conditioned attic, no more hot rooms on the second floor. These guys know their stuff."
"Called them because our master bedroom was always 5 degrees warmer than the rest of the house. Turned out the rim joists and attic knee walls had zero insulation. Fixed in one day. Problem solved."
"Did our entire shop building with spray foam. Metal building stays comfortable year-round now and my HVAC doesn't run nearly as much. Fair price, good crew, solid work."
"The estimator who came out for the quote really took time to explain closed cell vs open cell foam. That kind of knowledge and honesty is rare. The install went perfectly."
Frequently Asked Questions
How much does spray foam insulation cost in Charlotte, NC?
Spray foam insulation in Charlotte typically costs $1.50 to $3.50 per square foot for open cell foam and $2.50 to $6.00 per square foot for closed cell foam, depending on application area and thickness. Attic spray foam projects for an average 2,000 sq ft Charlotte home commonly run $2,500 to $6,500. We provide free detailed estimates so you know exactly what to expect before any work begins.
What is the difference between closed cell and open cell spray foam?
Closed cell spray foam (2-lb density) achieves R-6.5 per inch, acts as a vapor retarder, and adds structural strength -- it is the best choice for crawl spaces, basements, rim joists, and exterior walls in Charlotte's climate. Open cell spray foam (0.5-lb density) achieves R-3.7 per inch, is more flexible and better at sound control, and is commonly used in attics and interior walls. Our estimators will recommend the right type for each application in your home.
How long does spray foam insulation last?
Properly installed spray polyurethane foam (SPF) insulation can last the lifetime of your home -- typically 30 to 80 years. It does not sag, settle, or absorb moisture like fiberglass batt insulation. This permanence is one reason spray foam delivers a strong return on investment over time. Charlotte Expert backs all installations with a workmanship warranty.
Will spray foam insulation lower my energy bills?
Yes. Spray foam is the most effective insulation type for reducing energy bills because it both insulates and air seals in a single application. Charlotte homeowners typically see 30 to 50 percent reductions in heating and cooling costs after a full thermal envelope spray foam application. The tight air barrier prevents the conditioned air loss that wastes energy in traditionally insulated homes.
Is spray foam insulation safe for my family?
Once cured -- typically 24 hours after application -- spray foam insulation is inert, non-toxic, and completely safe. During application, our crews use full PPE including supplied-air respirators, and we ask homeowners to vacate the area during application and for 24 hours afterward. We follow all SPFA (Spray Polyurethane Foam Alliance) safety protocols on every job.
