Foundation Repair & Basement Waterproofing in Marshall County, Iowa

We cover all of Marshall County. That means Marshalltown plus Le Grand, Gilman, Laurel, Haverhill, Clemons, and the unincorporated areas in between. A rural address west of the Iowa River gets the same response and the same warranty as a job in town.

Marshall County sits on the Iowan Surface, where weathered clay till drains slowly and holds moisture against foundation walls. When Iowa River snowmelt and heavy spring rain saturate that ground, hydrostatic pressure pushes water through cracks, cove joints, and porous block. Interior drain tile, a sump system, and sealed walls move that water out before it reaches your floor.

Almost always, yes. Many Marshall County homes were built well before modern footings, on limestone, brick, or early poured walls. We stabilize those with steel piers, wall anchors or carbon-fiber straps, and targeted rebuilds rather than tearing anything out. The goal is to lock the original structure in place permanently.

It depends on the scope and whether you're inside Marshalltown or in unincorporated county jurisdiction. Structural repairs and many concrete projects require a permit; routine slab leveling often does not. We confirm the current requirement with the county or city office before we start and pull the paperwork for you so the job stays compliant.
