Why do floors sag over a crawl space that looked fine a few years ago? Older Millcreek homes with crawl space foundations sit exposed to spring groundwater rise, and over time that moisture rots support posts and beams faster than people expect. The floor above starts sagging long before anyone checks underneath.

Millcreek Foundation Pros looks at support posts, moisture, and structural beams together, since they're usually tied to the same root cause.

FAQs

Crawl Space Repair FAQs

Why does my basement smell musty every spring?

If your home has a crawl space, groundwater rise during snowmelt is often the source. Moisture travels up through an unsealed dirt floor and into the living space above.

How much does crawl space repair cost?

Depends heavily on scope. A simple vapor barrier costs much less than full encapsulation with support post repair.

How long does the work take?

Most jobs run from a single day for minor jack installs up to a few days for full encapsulation with multiple support posts.

Do I need a permit?

Only if you're replacing structural support posts or beams. Vapor barrier work generally doesn't need one.

Can I DIY this?

Basic plastic sheeting is fine as a DIY step. Sagging support posts and structural beam work need a professional, since it's load-bearing.
