Diagnosis First

Four Crawl Space Structural Findings and What Each One Means

Crawl space structural repair supports a floor that has sagged because a post settled or a beam lost support. A laser level survey and moisture readings show where the support path failed. Epp then sets an adjustable steel post beam jack on a new footing under the load bearing beam, or a helical pier under a post, and refers joist and beam carpentry to a framing contractor.

Read the Full GuideHide the Full Guide

A sagging floor over a crawl space can have more than one cause, so Epp finds the cause before recommending a repair. The most common causes are a support post that has settled into damp soil, a beam that sags between posts set too far apart, and wood weakened by years of crawl space moisture. Epp Foundation Repair has worked in crawl spaces across Nebraska, Iowa, Kansas, and Missouri since 1994. Every job starts with a laser level survey of floor elevations and moisture readings of the wood in the support path. The repair scope follows the diagnosis, not the other way around.

CH 01

What Crawl Space Structural Repair Covers

Epp's structural work in a crawl space is about support: the footings, posts, and piers that carry the beams, and the beams that carry the floor. When a post has settled or a beam needs another point of support, Epp places a new footing and sets an adjustable steel post beam jack under the load bearing beam. Where the soil under a post cannot carry the load, a helical pier can go directly under the post. In pier and beam crawl spaces, Epp replaces settled or rotted piers with steel supports.

Epp does not do framing carpentry. Epp does not sister floor joists, repair or replace floor joists, replace carrier beams or girders, install joist hangers, or replace sill plates. When the inspection finds a cracked, rotted, or undersized joist, a rotted beam section, or a soft sill plate, Epp notes it on the Customized Repair Estimate and recommends a framing contractor or general contractor for that work. Epp's crawl space inspection probes the joist ends and the sill plate on every visit, so the homeowner knows the condition of that wood before any support work begins.

CH 02

How a Post Beam Jack Goes In

A typical support repair follows this order. Survey and moisture readings. Epp's inspector reads floor elevation across the affected room, finds the lowest point, and traces the support path down to the ground. Temporary support. Crews may set temporary jacks to carry the floor while the permanent support goes in. New footing. A footing goes in at the support point, because a post on bare dirt can keep sinking. Steel post beam jack. An adjustable steel crawl space jack is set on the footing under the load bearing beam. Lifting, where the home allows. Some lift may be possible, but Epp never promises lift. How far and how fast a floor can come up depends on what the home will allow, and that is different on every project. Epp's foremen watch several things while lifting so they can get the most lift the home will take without damaging other parts of the house. Final survey. A closing laser level survey records where the floor ended up.

CH 03

Why Midwest Crawl Spaces Lose Support

Eastern Nebraska and western Iowa loess soil over glacial till can hold a perched water table through much of spring. A dirt floor crawl can sit in that water each spring, and a post footing in wet soil can settle. The soil also releases water vapor that can condense on cooler wood, and wood destroying fungi can grow once that wood stays damp. A chronically wet crawl can weaken posts and beams over time. The Kansas and Missouri clay belt adds expansive clay that swells when wet and shrinks when dry, which can move footings. Most homeowners notice the problem when a floor starts sagging or a door starts sticking.

CH 04

What Epp Does Not Do and Who Does

Epp sets permanent supports under beams and posts. Several nearby scopes go to other trades. Joist and beam carpentry, including sistering, joist repair or replacement, carrier beam or girder replacement, and joist hangers, goes to a framing contractor or general contractor. Sill plate replacement is carpentry at the connection between the house and its foundation; Epp's inspection identifies sill plate rot and refers it out. Subfloor leveling and hardwood refinishing are finish carpentry. Epp does not feather self leveling compound or refinish hardwood. HVAC ducts disrupted by access are HVAC contractor scope; Epp coordinates access and leaves openings clean but does not seal, insulate, or replace ducts.

CH 05

When Not to Do Structural Repair First

A new support set in a chronically wet crawl can face the same conditions that failed the original. Crawl space waterproofing and a sealed vapor barrier often come first, and support work follows once the water is under control. Epp may decline support work as a standalone scope if the moisture source is not being addressed by Epp or another trade.

Which Solution Is Right?

Which Crawl Space Structural Repair Fits

MethodFits whenNot a fit whenWarranty
Steel Post Beam Jack on a New FootingAn existing post has failed, or a load bearing beam needs another support point, and a new footing can be placed below it.The crawl is still chronically wet; a new support installed before the moisture is fixed can face the same conditions that failed the original.5 years from installation: the jacks stop further settlement of the repaired area. This warranty is not valid until full payment for work is collected, and moisture or humidity may require additional systems at the customer's expense.
Helical Pier Under a PostThe soil under a post cannot carry the load and the support needs to reach firmer ground.The crawl is still chronically wet and needs the moisture addressed first.Ask about the warranty that applies to your project
Referral to a Framing ContractorA joist is cracked, rotted, or undersized, a beam section is rotted or split, or the sill plate is soft.The wood is sound and the sag comes from a settled post or a beam that needs more support; that is support work Epp handles.Ask about the warranty that applies to your project

Regional Context

Why crawl spaces in Nebraska and Iowa need a sealed approach

Summer dew points routinely exceed 65 degrees across our service region, which means traditional vented crawl spaces pull humid outside air into the home all season. Combined with high water tables and clay backfill, vented crawls become mold incubators. Modern building science calls for sealed, dehumidified crawls in this climate.

Loess soils and the crack patterns they produce

Most of eastern Nebraska and western Iowa sits on wind-deposited loess, a fine, silty soil 10 to 200+ feet deep. Loess holds its structure when dry but loses cohesion rapidly when saturated. After a wet spring, saturated loess expands against foundation walls. After a dry Nebraska summer, it contracts, pulling away from footings, creating voids beneath slabs, and producing the vertical and diagonal settlement cracks we see most frequently on the Lincoln, Omaha, Council Bluffs corridor.

The Marshall and Sharpsburg loess series, dominant across the eastern Nebraska service area, are particularly prone to this cyclical volume change. Homes built in the 1960s, 1980s on uncompacted loess backfill show the highest incidence of progressive settlement cracking in our inspection data.

Frost depth, freeze-thaw cycles, and horizontal cracking

Eastern Nebraska's 36, 42" frost penetration depth means the soil below grade freezes and thaws 60, 80 times per year. Each cycle applies lateral pressure to basement walls. A wall that holds through ten cycles can fail in the eleventh if drainage has worsened, backfill has settled, or the wall was already at capacity. Horizontal cracks near the soil grade line are almost always a freeze-thaw story in this region.

In eastern Kansas, expansive clay pockets near the surface introduce a different failure mode. Consistent volume change regardless of frost depth. Horizontal cracking in Kansas foundations typically traces to clay expansion; the same pattern in Nebraska more often indicates frost-driven hydrostatic pressure.

"I tell every homeowner the same thing on a mold call: the spores aren't the problem, the water is. You can wipe down every joist with bleach and have it back in two months. Fix the moisture first, every time. That's been the rule since I started this work in 1994."

When this isn't the right fix

Don't set new crawl space supports in a chronically wet crawl without sequencing waterproofing first. A new support set in a humid crawl can face the same conditions that failed the original, and Epp may decline the work as a standalone scope until the moisture source is addressed.

The Process

How we approach Crawl Space Structural Repair

A straightforward path from initial inspection to completed repairs.

Step 01

Laser Level Survey and Moisture Mapping

Epp's inspector reads floor elevation across the affected room, finds the lowest point, and traces the support path down to the ground. Posts, beams, joist ends, and the sill plate in the affected area are probed and read with a moisture meter, and any wood that needs carpentry is noted for a framing contractor.

Step 02

Temporary Support and Crawl Access

Temporary jacks may be set at the failure points to carry the floor while permanent supports go in. They come out once the permanent supports carry the load. A clear access path is set up through the crawl entry and tarped to control dust in the living space above.

Step 03

New Footings and Steel Post Beam Jacks

A new footing goes in at each support point, and an adjustable steel post beam jack is set on it under the load bearing beam. Where the home allows, the floor is raised gradually, and a final survey records the result.
