Drainage, Grading & Crawlspaces

The enemy in the PNW is not a single storm. It is months of chronic moisture finding the lowest path. Grading, downspouts, and crawlspace condition are the three controls you have over where that water goes. A dry crawlspace in August proves nothing; check it in February.

WHY THIS MATTERS IN THE PNW

Our region’s rainfall arrives over months, not days. Chronic dampness, not flash flooding, is the enemy. A dry crawlspace in August proves nothing; check it in February. Standing water, efflorescence (white mineral bloom) on concrete, and musty odor are all early warnings worth acting on, not watching. Nathan is not a licensed professional engineer; his observations are informational, drawn from his 23-year career in structural engineering. Formal evaluations are performed by the licensed inspectors and engineers he helps coordinate.

[DRAINAGE FAQ: supply 3–4 questions: e.g. ‘How do I know if my crawlspace needs attention?’, ‘What does efflorescence mean?’, ‘How far should downspouts discharge?’]
