Concrete Work in Affton
Affton is a compact, established community, and concrete contractors in Affton mostly replace and repair flatwork on homes that have been lived in for decades. Affton is an unincorporated community and census-designated place in south St. Louis County, named for the area's first postmaster, Johann Aff. The 2020 census counted 20,417 residents and 9,579 housing units on just 4.57 square miles, a density of about 4,467 people per square mile. We pour driveways, front walks, steps, patios and garage slabs, and we repair concrete that has cracked, heaved or settled.
A community that peaked in 1970
Affton's population was 24,464 in 1970, its highest in the census record Wikipedia shows, and has held near 20,000 since 2000. That points to a housing stock built largely before the 1970s, which means driveways, walks and stoops that are 50 years old or more. On concrete that old, the common problems are scaling across the surface, broken aprons, front steps that have settled or pulled from the house, and patios that slope the wrong way.
Tight lots, careful work
With more than 2,000 homes per square mile, Affton lots are small and close together. Driveways are often narrow, and many run to a garage at the side or back. We plan each job for access, with truck placement, a pump or buggies where needed, and protection for lawns and the neighbors' property. On narrow drives, we pay close attention to edges and the joint where the drive meets the garage floor, since those are the spots that break first.
County government, county permits
As an unincorporated community, Affton has no city hall; local services come from St. Louis County, and roads may be county-maintained. For a driveway approach, curb cut or public walk, we check with St. Louis County Transportation and Public Works about what your address requires and handle any permit before we start.
Steps that last
Front steps are one of the most common Affton jobs. Older steps were often poured on shallow footings, and water from the roof and freeze-thaw cycles slowly undermine them. We remove the old steps, set a proper footing, form new steps with even risers and treads, and can set anchors for a handrail. If a gutter or downspout is dumping water at the base of the steps, we will point it out so the new work is not undermined the same way.

Affton Questions
Who handles permits for concrete work in Affton?
Affton is unincorporated, so local services come from St. Louis County. We check with the county about your address before scheduling.
My front steps have pulled away from the house. Can they be reattached?
Usually the base has settled, so reattaching does not last. Replacement with a proper footing is the lasting fix.
Can you widen a narrow driveway on a small lot?
Often, if setbacks and the right-of-way allow it. We check the lot and the county requirements before quoting.
