JLB Foundation Repair is a local company — not a franchise. We serve Winterset and the surrounding Des Moines metro with foundation repair, waterproofing, crawlspace encapsulation, and drainage solutions. Watch to learn who we are and how we work.
In Winterset's hilly Madison County terrain, homes frequently sit on or near shallow limestone shelves, so the clay pockets trapped between rock layers shift unevenly and pull foundations into differential settlement. JLB reads that uneven movement, then stabilizes it with steel push or helical piers and braces cracked, leaning basement walls before the damage spreads.
How we do it: foundation repair at JLB.
Because Winterset's slopes shed runoff toward older stone and block basements, water finds the mortar joints and hairline cracks first. JLB installs interior drain tile that channels seepage to a sump basin and pump, then seals active cracks from the inside, keeping the lower level of a covered-bridge-era home dry through Iowa's heavy spring rains.

Many of Winterset's historic-core houses rely on vented crawlspaces that trap humidity against limestone-shelf ground, breeding mold and musty air upstairs. JLB's approach is unusual: we spray foam both the crawlspace and the basement, sealing twice the surface against moisture for less than competitors charge to insulate just one.
How we do it: crawlspace encapsulation at JLB.
On Winterset's rolling lots, gravity carries surface and ground water straight at the foundation, especially where limestone near the surface blocks downward drainage. JLB regrades the soil away from the home, reroutes and extends downspouts, and trenches French drains that intercept that flow and carry it well clear of the walls.

When a Winterset basement wall has bowed past saving, often a century-old hand-laid stone wall worked loose by repeated freeze-thaw, patching no longer holds. JLB removes the failed section and rebuilds it in steel-reinforced poured concrete, footed below the 42-inch frost line so the new wall stands square against this county's clay and slope pressure.

The housing stock in Winterset dates primarily to the Historic town core (famous for covered bridges) with scattered modern residential growth.. Most homes sit on stone foundation and concrete block basement and crawlspace foundations — construction methods that were standard for the era but weren't designed to handle the soil movement we now understand. Foundations in Winterset often sit directly on or near limestone shelves. This can cause uneven settlement (differential settlement) as the clay pockets between rock layers shift. When the damage shows, homeowners here need foundation piering.
Hilly terrain in Madison County; high concentration of limestone bedrock near the surface. For many homes, eliminate musty odors and wall dampness is the first step.
What each warning sign means and how we fix it: foundation repair, waterproofing, and crawlspace encapsulation.
Numbers That Speak for Themselves
Foundations built before the 1950s have been absorbing soil pressure for over 70 years. If your Winterset home is showing cracks, sticking doors, or basement moisture, a free estimate tells you exactly what's going on — before it gets expensive.
Not Sure What You're Dealing With?
Click any symptom below to learn what it means, what's likely causing it, and how we can help. Most of these are more common — and more fixable — than you'd think.
Diagonal, stair-step, or horizontal cracks in drywall, plaster, or brick usually trace back to soil movement beneath your foundation. The heavy clay soils in the Kansas City and Des Moines metros expand and contract seasonally, which can shift your foundation over time. The good news: this is very fixable with the right approach.
Water entering through floor joints, wall cracks, or seeping through porous concrete means groundwater pressure is pushing moisture into your basement. An interior drainage system and sump pump can solve this permanently — and we can usually have it done in a day or two.
When a foundation settles unevenly, it can shift your home's frame just enough to make doors and windows bind. This is one of the earlier signs of foundation movement — and catching it early often means a simpler, less expensive repair.
That musty smell is moisture. Up to 40% of the air in your home rises from below — from your crawlspace and basement. If there's excess humidity down there, it affects your whole home. Encapsulation seals it out, and you'll notice the difference in your air quality right away.
Floors that slope toward the center or an exterior wall usually mean the support structure underneath needs attention. Push piers can stabilize your foundation and often lift it back to level — giving your floors a second life.
Water collecting near your foundation means your grading or drainage isn't directing water away effectively. French drains, regrading, extended downspouts, and drain pipes can redirect water away from the house — protecting your foundation for the long haul.
A basement wall that has bowed more than 2 inches inward, shifted off its footing, or shows multiple structural cracks may have moved beyond what bracing can fix. When carbon fiber straps, I-beams, or wall anchors are not enough, the wall needs to be removed and rebuilt with reinforced concrete. This is the last resort — but it is the permanent fix when the wall itself is compromised.
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."

The most common issues we see in Winterset are wall cracks (mortar deterioration and inward leaning in stone walls), basement water intrusion, uneven or settling floors, and doors or windows that stick. Foundations in Winterset often sit directly on or near limestone shelves. This can cause uneven settlement (differential settlement) as the clay pockets between rock layers shift. All of these trace back to how Madison County's expansive clay interacts with the specific foundation types in your neighborhood. For homes with crawlspaces, encapsulation that protects your air quality addresses the moisture side of the equation.
Foundation repair costs in Winterset vary widely based on the scope of damage and the solution needed. Minor crack repairs may cost $500-$2,000. Pier installation for settling foundations typically ranges from $5,000-$15,000. Full waterproofing systems run $3,000-$12,000. We provide free estimates with detailed, written estimates — no surprises and no pressure.
A JLB technician visits your Winterset home and examines the foundation inside and out — checking for cracks, wall movement, floor levelness, moisture, and drainage. For stone foundation foundations common in Madison County, we look for the specific failure patterns associated with that construction type. The inspection takes about 45 minutes and ends with a clear explanation of what we found, what (if anything) needs repair, and exactly what it costs. There's no obligation.
