Foundation Repair & Basement Waterproofing Across Greene County, Iowa

Greene County homeowners trust JLB for foundation repair and basement waterproofing across the county seat of Jefferson and the surrounding communities of Grand Junction, Churdan, and Scranton. The flat, highly productive ground along the North Raccoon River drains slowly, so saturated clay soils press on basement walls and pool around slabs year-round. Our crews bring one consistent standard of foundation repair and basement waterproofing to every Greene County address, whether you sit near the carillon tower downtown or out toward the county line.

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

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

Steel push pier foundation stabilization in Greene County, Iowa

Foundation Repair in Greene County

Greene County's flat river-valley ground and heavy Iowa clay create steady soil pressure and seasonal movement that crack and shift foundations over time. JLB repairs settling and bowing foundations across Jefferson, Grand Junction, and Churdan with engineered solutions like steel push piers, helical piers, wall anchors, and carbon-fiber reinforcement matched to what your home actually needs. Every repair starts with a free, no-pressure inspection and a clear written plan.

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 Greene County

Because the land around the North Raccoon River drains slowly, Greene County basements take on water through wall cracks, cove joints, and porous block long after a storm passes. We stop it with interior drain tile, sump pumps with battery backup, crack injection, and vapor barriers that move water out instead of letting it sit against your foundation. The result is a basement that stays dry through spring melt and heavy summer rains alike.

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 Greene County, Iowa

Crawlspace Encapsulation in Greene County

Damp crawlspaces are common under older Greene County homes and farmhouses, where ground moisture wicks up through bare soil and feeds mold, rot, and wood-destroying pests. JLB seals the space completely with a heavy-duty vapor barrier, and our standout approach spray foams both the crawlspace and the basement for double the protection at a lower cost than crews that treat only one. A drier crawlspace means cleaner air and a healthier home above it.

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 Greene County, Iowa

French Drains & Drainage in Greene County

The level, water-retaining soils throughout Greene County mean rainfall and snowmelt often have nowhere to go but toward your foundation. We design French drains, downspout extensions, regraded yards, and buried drain pipe that carry water well away from the house before it can pool against the walls. Proper exterior drainage is the first line of defense for any Jefferson-area basement.

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 Greene County

When a basement wall in an older Greene County home has bowed, sheared, or deteriorated past the point of reinforcement, JLB rebuilds it from the ground up. We excavate, remove the failing wall, and install a new structurally sound foundation wall engineered for the area's clay-driven soil pressure. It's the permanent answer when cracks have moved beyond what anchors or carbon fiber can safely hold.
