Upon evaluating the property at 140 Grand Ave, key findings reveal significant water intrusion
issues:
Moisture Levels:Moisture meter readings show wall moisture between 16% and 29% across
the external Beekman Street wall, the internal load-bearing wall on the driveway side, and the
enclosed porch. These levels indicate widespread moisture penetration.
Ceiling and Roof Sheathing:At the intersecting rooflines the spray foam at the roof sheathing
and rafters is waterlogged, with moisture content hitting 50%, the maximum detectable by the
moisture meter. This suggests severe water retention, impacting structural integrity.
** As noted in the image below above 16% moisture in wood is considered high.
