Home Inspectors in TigardOR

Tigard is a city in Washington County in the southwest Portland metro area, where the terrain is a mix of low ridgelines and shallow valleys that drain toward the Tualatin River, creating pockets of seasonal wetland and high-water-table conditions that affect foundation performance and crawl space moisture in certain neighborhoods. The dominant soil types in this part of the Tualatin Valley are Quatama and Aloha silt loams, which are moderately well-drained but become saturated during the wet season from October through April, a period when crawl space flooding and foundation drainage failures are most likely to occur. Housing in Tigard spans from post-WWII ranch homes and 1960s split-levels in established neighborhoods near the downtown core to large-scale suburban subdivisions built in the 1990s and 2000s near Highway 99W and I-5. The crawl space is the dominant foundation type for pre-1990 construction here, and inspectors consistently find inadequate vapor barriers, disconnected or undersized foundation vents, and evidence of wood decay in floor framing and subfloor materials. Seismic risk from the Cascadia Subduction Zone and local crustal faults applies to all construction in the Portland metro, and the evaluation of cripple walls, mudsill anchor bolts, and chimney conditions is part of a thorough inspection. Oregon CCB licensing confirms an inspector's qualifications. There are 16 inspectors in the Tigard area.
