Crawl Space Mold Causes
Epp Foundation Repair has diagnosed crawl space moisture across Nebraska, Iowa, Kansas, and Missouri since 1994. Mold spores exist in every crawl space and only colonize when humidity stays high, so the question is never the spores. It is where the water is coming from.

Deteriorating Insulation
Fiberglass batts drooping between your floor joists or falling to the crawl space dirt. The insulation itself is the symptom. The cause is humid air and ground moisture that the insulation can no longer hold back.

Groundwater Seepage
Epp Foundation Repair has been installing interior crawl space drainage and sump systems across Nebraska, Iowa, Kansas, and Missouri since 1994.

High Energy Bills
Heating and cooling costs creeping up while your thermostat stays the same. A damp, vented crawl space pulls in outside air and lets conditioned air leak out through the floor. Your system runs longer to make up the difference.

Moisture in Crawl Space
Epp Foundation Repair has been encapsulating crawl spaces across Nebraska, Iowa, Kansas, and Missouri since 1994, dropping relative humidity to a stable, lower level.

Musty Smell From the Crawl Space
Epp Foundation Repair has traced musty odor complaints to crawl space moisture in Nebraska, Iowa, Kansas, and Missouri homes for more than 30 years. The stack effect carries the air from under the house up into the rooms you live in, so the smell upstairs is a report on how wet the crawl space is.

Pests & Rodents
Epp Foundation Repair has been sealing crawl space entry points across Nebraska, Iowa, Kansas, and Missouri since 1994. Encapsulation removes the open vents, dirt-floor burrows, and moisture that attract pests in the first place.

Sagging Crawl Space
Floors that bounce, dip toward the center of a room, or feel soft when you walk. The framing over your crawl space is no longer fully supported. The longer the wood carries that load unsupported, the more it deflects.

Sagging Floors
You feel this symptom upstairs long before you see its cause. Epp Foundation Repair walks the crawl space first to find out why the floor above it is moving.

Water in the Crawl Space
Epp Foundation Repair has installed crawl space drainage and sump systems across Nebraska, Iowa, Kansas, and Missouri since 1994. If there is water under your home today, the order is simple: stop the source if you can, get the water out, then fix the reason it came in.
