Gaithersburg Suburban Housing Stock & Copper Pinhole Leaks
Gaithersburg encompasses planned communities and suburban subdivisions including Kentlands, Lakelands, Montgomery Village, and Washingtonian Woods. In homes constructed between the 1970s and 1990s, domestic water distribution relies primarily on Type M or Type L copper piping.
Over decades of service, municipal chloramine disinfection combined with water velocity through copper fittings induces pinhole pitting corrosion. These microscopic leaks discharge fine water sprays behind baseboards and drywall, causing structural mold colonization and wood rot before water surfaces visibly.
