JLB Foundation Repair is a local company — not a franchise. We serve Newton 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.
Newton's old Maytag-era bungalows and early-1900s family homes were largely built on concrete block, and decades of expansive Jasper County clay swelling and shrinking with the seasons leaves those walls bowing inward and tracing stair-step cracks across the joints. JLB stabilizes them with steel piering and wall braces, then resets settled footings so the structure holds even when the clay heaves hard in a wet Iowa spring.
How we do it: foundation repair at JLB.
On Newton's rolling terrain, the clay-rich ground sheds water slowly and pushes it against block basements that already take a beating from soil heave. JLB installs interior drainage tile to a sump basin, then seals active cracks from the inside so seepage stops collecting under floors instead of rising into the finished space below.

Plenty of homes near Maytag Park and across older Newton sit over vented crawlspaces that pull in humid Iowa air all summer long. Rather than treating one level, JLB spray-foams both the crawlspace and the basement, sealing the whole envelope against moisture for twice the protection at a lower cost than crews that encapsulate only one or the other.

Where Newton's gently rolling lots channel runoff toward the house, standing water at the foundation is what gets the clay swelling in the first place. JLB cuts French drains to carry ground and surface water away, regrades the slope back from the walls, and extends downspouts well past the footing so spring rains drain off instead of pooling.

When a Newton block or stone basement wall has bowed and cracked past the point bracing can save, JLB takes it back to bare ground and rebuilds. The replacement goes in as steel-reinforced poured concrete set below the deep Iowa frost line, giving these manufacturing-town homes a wall engineered to resist the clay pressure that failed the original.

The housing in Newton spans multiple eras: Established manufacturing hub with a high percentage of mid-century bungalows and early 20th-century family homes. That range means you'll find concrete block basement, stone foundation, crawlspace foundations across different neighborhoods — and many eventually need correct uneven floors and sticky doors. Newton homeowners frequently deal with bowing walls in older block basements. The clay-rich soil undergoes significant 'soil heave,' putting intense pressure on foundations during wet Iowa springs.
Rolling terrain in Jasper County; soil consists of expansive clay that reacts heavily to seasonal moisture. For many homes, the right waterproofing system for your foundation type 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
The stone and limestone foundations common in Newton develop predictable crack patterns under years of clay pressure. A free estimate from JLB identifies the cause and gives you a clear plan — before the cracks become a structural issue.
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."
