What We Do in Avery County

Attic Insulation in Avery County

Wet, moldy or animal-soiled insulation comes out of Avery County attics, and a mouse-soiled Avery County attic is sanitized and deodorized; in the 13 percent of homes built before 1960, vermiculite is ruled out first.
Air Sealing in Avery County
Some 45 percent of Avery County homes heat with electricity, often through attic ducts; their joints and the ceiling's gaps are sealed first.

Homes in Avery County

Half of Avery County's 14,200 housing units were built before 1985: 19 percent before 1970, 35 percent before 1980 (nearly all before the state's 1978 insulation rule) and 6 percent in 2010 or later (16 percent statewide). The largest share went up in the 1980s; fiberglass from those years may have settled, so check its depth against the joists. Among Avery County towns, the median home is oldest in Grandfather Village (1980) and newest in Sugar Mountain (1985).
