Insulation Services in Birmingham, AL
Birmingham, Alabama insulation contractors in this directory cover Mountain Brook, Vestavia Hills, Hoover, Homewood, and central Birmingham. IECC Climate Zone 3A asks for R-38 attics and R-13+R-5 continuous walls. Most pre-2000 Birmingham homes have R-19 to R-30 of settled batts in attics and minimal wall insulation. Topping up the attic with blown cellulose or fiberglass runs $1.40-$2.20 per sq ft. Closed-cell foam in basements and crawlspaces lands $4.50-$7/sq ft at 2 inches.
Alabama Power and Spire (gas) offer home-performance rebates for qualifying air-sealing and insulation jobs. The 25C federal tax credit covers 30% of qualifying insulation up to $1,200/year. Birmingham's humid summers make crawlspace encapsulation especially valuable — vented crawlspaces drive moisture into the floor system year-round.
