Des Moines Foundation Repair and Basement Waterproofing

Most residential foundation repair projects in the Des Moines area range from $3,000 to $15,000 depending on the extent of damage and the number of steel push piers needed. Piers typically cost $1,250–$2,500 each, and most central Iowa homes need 5–10 piers. Des Moines homes built on glacial till deposits tend to experience settlement differently than Kansas City clay — it's often slower but steady, meaning damage accumulates over years before homeowners notice. JLB provides free on-site inspections with written estimates.

Des Moines sits on glacial till and loess deposits — dense, clay-heavy soils left behind by glaciers thousands of years ago. These soils have poor drainage and hold water against foundation walls, creating hydrostatic pressure that causes horizontal cracking, bowing, and water intrusion. Iowa's 42-inch frost depth drives the freeze-thaw cycle deeper than most Midwest states, meaning the soil around your footings heaves and settles more aggressively each winter. Spring snowmelt combined with a rising water table (2–3 feet below grade in some areas) creates a double hit.

Absolutely. Central Iowa receives approximately 36 inches of precipitation annually, and spring snowmelt can raise the water table to within 2–3 feet of the surface in many Des Moines neighborhoods. The glacial till soil drains poorly, meaning water accumulates against basement walls for days after rain events. Interior waterproofing with drain tile and a sump pump captures this water at the wall-floor joint and removes it before it damages your home. Most systems cost $3,500–$8,000 and provide permanent protection — a fraction of what water damage repairs would cost.

Older neighborhoods like Beaverdale, Sherman Hill, Drake, and Highland Park tend to have more foundation issues due to housing age (many homes built 1920s–1960s), older construction methods, and decades of soil settlement. However, newer developments in Ankeny, Waukee, and Grimes also experience problems — rapid construction during the 2000s housing boom sometimes outpaced proper soil compaction. Every neighborhood in the Des Moines metro sits on the same glacial till base, so no area is immune. The difference is usually housing age and construction quality.

Yes. JLB Basement Waterproofing & Foundation Repair serves the entire Des Moines metro with crawlspace encapsulation. Our dual-seal approach spray-foams both the crawlspace and the basement for twice the protection at a competitive price — most competitors only seal one or the other. Iowa's high humidity and deep frost cycles make crawlspace moisture control especially important. Unsealed crawlspaces push mold, humidity, and cold air into your living space through the stack effect, raising energy costs and lowering indoor air quality.

Our service area includes Des Moines, West Des Moines, Ankeny, Ames, Urbandale, Waukee, Johnston, Altoona, Clive, Grimes, Marshalltown, Newton, Indianola, Boone, Pleasant Hill, Pella, Bondurant, Perry, Knoxville, Nevada, Adel, Polk City, Windsor Heights, Winterset, and Carlisle. We cover Polk, Dallas, Warren, Story, and surrounding counties.

Foundation repair can be done year-round in Iowa, but spring through fall is the most common window. After the ground thaws (typically mid-March), crews have better access to excavation sites and soil conditions are more predictable. However, if you notice active cracking, bowing walls, or water intrusion in winter, don't wait — the damage accelerates with each freeze-thaw cycle. Iowa's 42-inch frost depth means the soil around your foundation heaves and settles more than almost any other state. Early repair prevents escalation.

Most standard homeowners insurance policies in Iowa do not cover foundation damage caused by soil movement, settling, or normal wear. Insurance typically covers sudden events like a burst pipe that undermines the foundation, but not gradual settlement. Some policies may partially cover water damage if a covered peril caused the intrusion. JLB offers flexible financing options to make foundation repair accessible. We recommend checking with your insurance provider for your specific coverage, and we're happy to provide documentation that may support a claim.
