Keeping water out of the basement: what’s actually worked for you?

surfer308709 · 2026-05-19T21:40:52Z

Here’s what I did when my basement started resembling a swimming pool last spring: First, I checked the gutters and downspouts, made sure they were clear and pointing away from the house. Then I patched up any visible cracks in the foundation with hydraulic cement (messy job, not gonna lie). After that, I added a sump pump—kind of pricey but it’s saved me more than once. Anyone got a better trick or something less labor-intensive? Curious if there’s a magic bullet I’m missing here.

- Been in the trenches with this stuff for years.
- Honestly, exterior membranes are overkill for most houses unless you’ve got a serious groundwater issue or a really old foundation.
- I’ve seen folks spend a fortune and still get leaks because they ignored the basics—grading, gutters, downspouts.
- Did a job last fall where we just extended the downspouts and patched a couple cracks. Basement’s been bone dry since.
- Not saying membranes never help, but for most people, simple fixes do more than you’d think.
