JLB Foundation Repair is a local company — not a franchise. We serve Pella 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.
Pella's blend of meticulously kept European-style historic homes and 1970s-2000s neighborhoods means JLB sees everything from settling stone footings near Washington Street to cracked block walls in newer subdivisions. As Marion County's expansive clay swells and shrinks with the seasons, walls bow and corners drop, so we stabilize them with steel push piers and engineered wall anchors matched to each home's age.

Sitting on a high prairie plateau between the Des Moines and Skunk Rivers, Pella basements still take on water when clay-bound soil holds rain against the walls. JLB stops that seepage at the source with interior drain tile, a sealed sump system, and crack injection, keeping aging block and poured basements dry without disrupting the high-value finishes Pella homeowners protect.

Humidity drifting up through bare crawlspace dirt rots joists and feeds mold in Pella's older housing stock long before owners notice. Rather than treating one level, JLB spray foams both the crawlspace and the basement, sealing the whole below-grade envelope against the moisture that Marion County's clay soil pushes inward, often for less than competitors charge to encapsulate just one space.

Because Pella's plateau lots shed runoff toward the river valleys, poor grading and stubby downspouts dump water straight against foundations. JLB reroutes that flow with French drains, regraded soil, and extended downspout lines, carrying surface and groundwater well past the home so saturated clay never gets a chance to load the walls after a heavy Iowa storm.

When a stone or block wall in one of Pella's century-old homes has bowed past saving, patching only delays collapse. JLB rebuilds the failed section entirely, pouring steel-reinforced concrete set below the frost line so the new wall resists the freeze-thaw heaving and expansive-clay pressure that broke the original, restoring structural strength to homes valued for their historic character.

The housing stock in Pella dates primarily to the Unique mix of meticulously maintained historic European-style homes and stable 1970s-2000s residential growth.. Most homes sit on stone foundation and concrete block basement and poured concrete basement foundations — construction methods that were standard for the era but weren't designed to handle the soil movement we now understand. Pella's high property values make foundation maintenance a priority. Aging block basements are susceptible to moisture seepage from the expansive clay common in Marion County. When the damage shows, homeowners here need underpinning that bypasses problem soil completely.
High prairie plateau between the Des Moines and Skunk Rivers. Proximity to water means higher water tables and more hydrostatic pressure on foundations — making waterproofing designed for heavy clay soil essential for many homes.

Numbers That Speak for Themselves
Foundations built before the 1950s have been absorbing soil pressure for over 70 years. If your Pella 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."
