You might have new flooring and fresh paint\u2014but if the home is settling, shifting, or collecting water underneath, that\u2019s the stuff that really counts. My Mindset in a Crawlspace or Basement I\u2019m not just glancing for water. I\u2019m looking at the support systems. Are piers solid, straight, and continuous? Are they resting on proper footings or makeshift blocks? Is there evidence of movement, like gaps between beams and supports, or diagonal cracking in stem walls? Foundation systems vary\u2014slab-on-grade, post and pier, basement, stem wall, pilings\u2014but the approach is the same. I\u2019m looking for settlement, shifting, and moisture. I\u2019m also checking whether repairs have been made\u2014and how well. Foam shims and cardboard spacers aren\u2019t load-bearing materials (no matter how clever the last guy thought he was). Moisture Is the Common Denominator Water doesn\u2019t belong inside a crawlspace or basement. I check for efflorescence (that white powdery residue from water seepage), dark staining, standing water, and mold-like substances. These may not just mean dampness\u2014they may point to poor drainage or a failing sump pump system. Sump Pumps: What I Can and Can\u2019t Test If the sump pump is exposed and I can reach it safely, I\u2019ll inspect its condition. I look for power supply, float switch condition, visible rust or deterioration, and backup battery systems. If there\u2019s standing water or a test button, I may activate it. But I don\u2019t manually fill sump pits, override systems, or perform destructive testing. If it's a sealed system or inaccessible due to safety or design, I\u2019ll document what I can see\u2014and note that further evaluation may be needed. What I\u2019m Looking For\u2014And What I\u2019m Not \u2705 I\u2019m looking for: uneven floors, cracked foundation walls, displaced piers, sagging framing, long-term moisture, and signs of movement. \u274c I\u2019m not looking to: conduct soil tests, certify foundation engineering, test underground drainage, or predict how the home will settle over the next decade. When I Flag a Structural Concern If I see horizontal foundation cracks, wall bowing, improper support spacing, or sloped floors beyond normal tolerance, I\u2019ll let you know. These signs don\u2019t always mean disaster\u2014but they do mean a structural contractor should take a deeper look. Just like a knee specialist doesn\u2019t diagnose from an x-ray alone, you need boots-on-the-ground expertise for repairs and solutions. FAQs: Understanding Foundation and Basement Inspections Do you test the sump pump? Only if safely accessible and testable without altering the system. I\u2019ll report visible condition and note if testing was limited or not possible. If it\u2019s sealed, damaged, or inaccessible, I\u2019ll recommend evaluation by a plumber or drainage contractor. Will you tell me if the foundation is bad? I\u2019ll report cracks, movement, sagging, or signs of distress. But a full engineering opinion is beyond the scope of a home inspection. My goal is to tell you what\u2019s visible, and whether it warrants a second look. Do you enter crawlspaces even if they\u2019re tight? Yes\u2014if safe and accessible. I\u2019ll crawl, duck, and inch through to get eyes on the piers and framing. If entry is blocked or dangerous, I\u2019ll document that in your report. What foundation types do you inspect? I inspect slab, post and pier, stem wall, and basement foundations. Each has different issues\u2014but the same red flags: water, settlement, and failing support systems. \u2192 Next up: Post 14: Do You Have Good Bones?
