We used Carolina Weatherization for our crawl space, attic, sealing all vents and ducts, and to insulate the outside of our daughter's room which is over the garage. From start to finish, Matt and his crew were incredibly professional, polite, and did an amazing job. They kept me informed of their progress multiple times a day. The finished product was excellent. I can't believe how good the crawl space looks now, and more importantly we can feel a substantial change in how our home feels. I can't wait to start seeing lower energy bills! I can't recommend Carolina Weatherization enough!
