Questions about Drainage & Water-Flow Audit

Clear answers first. If one question changes the deal, bring it into the review before you move money.

Q1Why is drainage the most under-appreciated condition issue here?+

Because slopes and a near-lake water table make water the hidden driver behind wet crawlspaces, foundation problems, and failing walls — and "it was just a wet week" is how buyers talk themselves past it. Watch where water actually goes.

Q2When's the best time to see a lot's true drainage?+

During or right after a storm. Standing water, soggy soil, splashback staining, and erosion channels reveal themselves when it's raining and hide when it's dry — which is exactly when listing photos are taken.

Q3What's the difference between a drainage issue and a structural one?+

Drainage is the cause; structural movement is often the effect. If water reaches the foundation or crawlspace, that's a decision-changer worth a drainage contractor's estimate — fixing water early can prevent the structural bill.

Q4What should I look for around a driveway or patio?+

Whether the hardscape is pitched toward the house. A driveway or patio that drains at the foundation feeds water exactly where you don't want it, and it's a common, fixable-but-real finding on slope lots.

Q5Where does uphill or neighbor water fit in?+

It's a common slope complication: water crossing onto the lot needs interception via swales or area drains. The fix depends on volume and property lines, so map where it enters before assuming it's minor.

Q6The crawlspace shows water lines — deal-breaker?+

Not necessarily, but get an estimate. The range runs from regrading and downspout fixes to a full perimeter drain and sump. Price it before you accept — that's what a Real Estate Review helps you do.
