Building in Marshalltown and Marshall County
Marshalltown is the Marshall County seat with about 27,600 residents, and it is the largest city we serve outside the metro. It sits on Highway 30 with straightforward access from every direction.
Marshalltown carries something most Iowa towns do not: a recent history of severe storm damage. The 2018 tornado and the 2020 derecho both hit here. That shapes the work. We see repair-driven remodels, roof-structure questions on homes that took wind load. Clients who reasonably want to know how a new addition will be tied down.
We answer that with fastening and bracing details rather than reassurance. If a client wants an addition built to handle what the last decade delivered, that is a design conversation worth having at the start.
The housing itself spans a century, from courthouse-square era homes to postwar neighborhoods to newer edges. The older stock hides the usual: cast iron, galvanized supply, and undersized panels.
Footings go 42 inches down at minimum to sit under Iowa’s frost line.
We build across Marshall County. Homeowners in State Center, Melbourne, Haverhill, and Ferguson call us for the same work.
