Environmental Testing in New Hampshire
Mold, Asbestos & Lead Test Kits

New Hampshire has a very high concentration of pre-1940 housing relative to its population. Manchester, Nashua, Concord, and many smaller New Hampshire mill towns and river valley communities have extensive older housing where lead paint is nearly universal. The state's mill towns in particular — many built in the 19th and early 20th century — have dense concentrations of pre-war housing with significant lead and asbestos hazards.

Asbestos pipe insulation is common in older New Hampshire homes with steam and hot water heating systems, which were standard through the mid-20th century. Floor tiles, ceiling tiles, and exterior transite siding also frequently contain asbestos in pre-1980 construction. Testing before any renovation or HVAC work in an older home is strongly recommended.

New Hampshire's seasonal climate creates mold risk from basement moisture, snowmelt infiltration, and the freeze-thaw cycle. Older homes with aging drainage and inadequate waterproofing are particularly vulnerable.
