Homeowners cannot identify hazardous building materials in older homes without expensive professional inspection

Owners of pre-1920s homes encounter unidentified materials (like horsehair plaster) in walls and ceilings but lack accessible ways to determine if they're asbestos, lead-containing, or other health hazards. Current solutions require hiring expensive contractors or specialists, creating delays and anxiety while living in potentially unsafe conditions. DIY homeowners turn to forums because they need fast, affordable identification before renovation work begins.
