A wet, moldy, or structurally compromised crawl space affects the air quality, energy efficiency, and structural integrity of every floor above it. Epp Foundation Repair has been diagnosing and repairing crawl spaces across the Midwest since 1994, with structural reinforcement, moisture control, and drainage solutions built for our regional clay soils and seasonal groundwater patterns.
A local specialist will inspect your foundation, walk you through the findings, and send a clear estimate, no cost, no pressure.
Crawl Space Repair problems rarely come from one cause. We specialize across the full range of crawl space repair methods so the solution matches the cause. Not the easiest sale.
01 Crawl space waterproofing addresses active water reaching a dirt-floor or short-clearance crawl. Interior drainage matting at the perimeter, a sump pit with pump, and a polyethylene vapor barrier capture seepage and discharge it outside. Epp Foundation Repair has designed crawl-space drainage and encapsulation systems across NE, IA, KS, and MO since 1994.

02 Crawl space structural repair supports the floor from below when a post has settled or a beam has lost support. Epp Foundation Repair sets adjustable steel post beam jacks on new footings and can place helical piers under posts across NE, IA, KS, and MO. Joist and beam carpentry is referred to a framing contractor.

03 Pier and beam homes sit on individual piers that carry beams, which carry the joists, and they usually fail at the piers first. Epp Foundation Repair replaces settled or rotted masonry, concrete, and wood piers with helical piers driven to bearing strata across NE, IA, KS, and MO, and has since 1994. Rotted beam or joist carpentry is referred to a framing contractor.

04 Crawl space sump pump installation captures groundwater inside a sealed basin set into the dirt floor, lifts it through a check-valve discharge line, and moves it 6 to 10 feet from the foundation. Epp Foundation Repair installs crawl-space sumps in dirt-floor crawls with limited clearance across NE, IA, KS, and MO, typically as a pre-encapsulation step or paired with interior crawl-space drainage matting.

05 Crawl space drainage systems intercept wall seepage and groundwater at the perimeter, channel it through low-profile drainage matting and perforated pipe under the dirt floor, and feed it to a sump pit that pumps it 6 to 10 feet from the foundation. Epp Foundation Repair installs full crawl-space drainage systems across NE, IA, KS, and MO, designed for limited clearance and regional soil conditions.
