Built on dissected hills, Audubon's homes rest on loess capping an older clay-rich till that swells and shrinks with every wet-dry season. JLB stabilizes the resulting settlement and stair-step cracking around the courthouse square with helical and push piers, and braces the leaning stone and early block walls common in the town's late-1800s core.
Because so much of Audubon drains down the slopes toward the East Nishnabotna River, water collects against lower foundations and pushes through aging mortar joints. JLB installs interior drainage tile and a sump system to relieve that pressure, then seals the active wall cracks so seepage stops tracking into basements during spring melt and heavy summer storms.
Audubon's older homes near Albert the Bull and John James Audubon Park trap humid air in stone-walled crawlspaces, feeding mold and musty odors. JLB's approach is what sets it apart: spray foam goes on in both the crawlspace and the basement, sealing the whole substructure against moisture at a lower cost than crews who treat only one level.
On Audubon's hilly, loess-mantled lots, runoff sheets downhill and pools wherever the grade flattens near the house. JLB reads how each property drains toward the East Nishnabotna, then combines French drains, regraded soil, and extended downspouts to carry both surface and ground water well clear of the foundation before it can saturate the clay subsoil.
When a hand-laid stone or early block wall has bowed past saving under repeated frost heave, patching no longer holds. JLB rebuilds it entirely, pouring a new steel-reinforced concrete wall set below the local frost line so Audubon's clay till and repeated freeze-thaw cycles can no longer work it loose.

Albert the Bull, the world's largest bull statue, has marked Audubon as cattle country since 1964, and the town built around him stays true to that identity — a county seat anchored by beef production, a working livestock economy, and the Audubon Community School District. JLB runs to this corner of west-central Iowa from its Van Meter office at (515) 642-3406, the closest crew base to a town that sits roughly 85 miles from Des Moines and about 75 from the Omaha–Council Bluffs area. We work it the way a neighbor would: a free on-site look, an in-house crew, and a plan shaped by where each home actually sits on Audubon's rolling ground.
Audubon's growth has pushed newer homes onto lots that were farm ground or pasture a generation ago, and those newer foundations are where settling shows up first. Fresh excavation and backfill take years to fully consolidate, so a poured wall or slab placed on disturbed ground can drop unevenly while the older basements near the courthouse square sit comparatively still. Under all of it lies loess draped over a weathered Pre-Illinoian clay till — a deep, water-grabbing subsoil that firms up dry and softens wet, and on Audubon's dissected slopes that moisture rarely sits evenly under a footing. JLB reads that pattern of newer-development movement before recommending piers, so the fix matches how a young foundation is actually loading the ground beneath it.
JLB provides foundation repair and basement waterproofing throughout Audubon and Audubon County — from the older homes around the courthouse square and Albert the Bull to places spread out along U.S. Highway 71 and Iowa Highway 44. Our crews understand how this hilly west-central Iowa ground, with its loess-over-clay subsoil, moves against a foundation.
Numbers That Speak for Themselves
The loess-over-clay ground under Audubon swells against your basement walls every wet season and pulls back when it dries, while a winter of freeze-thaw works moisture into aging mortar joints.
Not Sure What You're Dealing With?
Audubon sits on loess over an older Pre-Illinoian clay till — water-holding ground well off the flat plain near Des Moines. JLB designs every repair around how this dissected, slope-draining subsoil swells, shrinks, and presses on a foundation, instead of applying engineering tables meant for other parts of Iowa.
Homes on Audubon's hills take downhill water that collects against basement walls and works in through cracks, mortar joints, and the wall-floor cove. JLB designs interior drainage and sump systems for the seepage that follows the terrain draining toward the East Nishnabotna River.
From hand-laid stone and early block basements around the Audubon County Courthouse square to newer poured walls up the slope, JLB carries the equipment and training to repair every foundation type found across this west-central Iowa town's housing stock.
JLB is a local company, not a franchise, serving Audubon from its Van Meter office. Both the assessment and its written price cost nothing, and what JLB will do gets spelled out in writing before the job starts on your house.

What Our Customers Say
"We had cracks running up our walls and doors that wouldn't close. JLB came out, explained exactly what was happening with the soil under our house, and had the piers installed in two days. Floors are level again. Wish we hadn't waited so long."
"Three other companies gave us the runaround. JLB showed up, did a thorough inspection, and gave us a straight answer. The repair held up through an entire Missouri winter with zero new cracking."
"Our crawlspace was a mess — moisture, mold, the works. JLB encapsulated it AND spray-foamed our basement in the same project. The difference in our home's air quality is incredible. Great value for the price."

For most projects, permitting and inspection run through the City of Audubon for properties inside the city limits, while work on rural parcels falls under Audubon County. Structural foundation repair and new basement walls are the jobs most likely to require a permit, whereas a minor crack seal often does not — the threshold varies by project, so it's worth a quick call to the city or county before scheduling. The Audubon County Assessor's office is also a useful stop for confirming property details. JLB handles Audubon work to code and will tell you up front whether your specific repair or pour needs a permit pulled and an inspection scheduled.
Yes. For Audubon homes with a crawlspace, JLB seals the space with a heavy vapor barrier and spray foam to shut out the ground moisture that keeps a dirt or block crawlspace damp through the seasons. What sets JLB apart is spray-foaming both the crawlspace AND the basement rather than treating just one — many contractors stop at a single area, but doing both gives an Audubon home twice the moisture and air-sealing protection, and JLB delivers it for less than competitors who handle only one. The result is a drier, more stable, more energy-efficient home from the footing up.
Late spring through early fall is the easiest window for foundation work in Audubon, because the ground has thawed and excavation is straightforward. That said, interior repairs — like an interior drainage system, a sump pump, or carbon-fiber wall reinforcement — can be done year-round since they happen inside the basement and don't depend on the weather outside. If you're seeing active cracking, bowing, or water now, don't wait for an ideal season; JLB can assess the home in any month and stage the outdoor portions for when conditions cooperate.
The repair depends on how far the wall has moved. For a wall that's bowing inward from the clay's lateral pressure, JLB typically reinforces it with carbon-fiber straps on lighter deflection or steel wall anchors that tie the wall back to stable soil and can pull it back over time on more serious bowing. Straight vertical or stair-step cracks without major displacement are often sealed and reinforced rather than rebuilt. On Audubon's older hand-laid stone and early block basements, repointing failed mortar joints and adding interior waterproofing frequently goes hand in hand with the structural work. JLB matches the method to the wall after a free on-site inspection — no two basements move the same way.
Tell us about your Audubon home — where it sits on the slope, how old it is, and what you're seeing. Our team schedules an on-site inspection that accounts for the town's loess-over-clay subsoil, the downhill drainage toward the East Nishnabotna, and your specific foundation type.
