Foundation Repair, Basement Waterproofing & Crawlspace Services in Boone County, Iowa

One local crew handles the whole structural side in Boone County — piering, waterproofing, crawlspace encapsulation, drainage, and wall replacement. Here's how we fix each:

Steel push pier foundation stabilization in Boone County, Iowa

Foundation Repair in Boone County

Boone County's expansive Des Moines Lobe clay swells and shrinks through Iowa's wet springs and freezing winters, and that movement shows up as stair-step cracks, sticking doors, and settling near the dramatic river-valley grades. JLB stabilizes homes in Boone, Boxholm, and the surrounding towns with steel push piers and helical piers driven to load-bearing strata, then lifts and locks the foundation back to level so the damage stops spreading.

Steel push piers and helical piers driven to stable load-bearing soil
Wall anchors and carbon-fiber straps for bowing or cracked walls
Engineered, permanent fixes — not surface patches
Transferable warranty and a free, no-pressure inspection

Basement Waterproofing in Boone County

Wet basements are a constant in Boone County because the heavy glacial till holds water and feeds hydrostatic pressure against foundation walls every time the snow melts or a thunderstorm rolls through. We waterproof from the inside with interior drain tile and reliable sump systems, and from the outside with membrane sealing and grading corrections, keeping basements dry from the county seat out to rural Boxholm.

Interior drain tile and sump systems sized for Iowa’s water table
Crack injection and wall-to-floor joint sealing
Vapor barriers and dehumidification to stop musty air and mold
Keeps the lower level permanently dry, backed in writing

Crawlspace encapsulation with vapor-barrier liner in Boone County, Iowa

Crawlspace Encapsulation in Boone County

Crawlspaces under older Boone County homes draw in damp air from the clay-heavy ground, breeding mold, wood rot, and that musty smell that creeps upstairs. JLB seals the space with heavy-duty vapor barriers and, as our standout offering, spray foams both the crawlspace and the basement for twice the protection at a lower cost than crews that treat only one space.

Spray-foams BOTH the crawlspace AND the basement — twice the protection
Sealed vapor-barrier liner over floor and walls
Cuts humidity, mold, and energy loss from the stack effect
Done for less than competitors who seal only one or the other

French drain trench with gravel and drain pipe in Boone County, Iowa

French Drains & Drainage in Boone County

With slow-draining till and the rolling terrain of the Des Moines River valley, surface and subsurface water tends to pool against Boone County foundations instead of running off. We install French drains, extend downspouts well away from the home, and reshape grading so water is carried off before it can saturate the soil and pressure your basement walls.

French drains, regrading, and buried downspout extensions
Redirects surface and groundwater away from the foundation
Relieves the hydrostatic pressure that cracks walls and floors
Built for Iowa freeze-thaw and heavy spring snowmelt

Foundation Wall Replacement in Boone County

When a Boone County foundation wall has bowed, cracked badly, or crumbled from decades of clay pressure and freeze-thaw cycles, repair alone won't restore its strength. JLB removes and rebuilds the failed section with properly reinforced, code-compliant walls, then pairs the new structure with drainage upgrades so the same soil forces don't undo the work.
