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."
