Rise and Run: Measure Your Concrete Stairs First

Concrete steps are either poured in place, with forms built at your door, or precast in a plant and set as a finished unit. Tired steps usually need one of three things: a patch at the edges, a lift back into position, or replacement. The choice depends on whether the concrete is damaged, the whole set has moved, or both. Five minutes with a tape measure tells you more than any photo.

Take two measurements

  1. Total rise: set a straight board level on the threshold, run it out past the bottom step, and measure down to the walk.
  2. Each riser: measure every step at the same spot, from tread to tread, and note the tallest and the shortest.
Common rises worked out at the 7 3/4-inch maximum riser, with 10-inch treads and a 36-inch landing

The risers tell the story. Steps that started out even and now differ by more than 3/8 inch have usually moved or worn. A landing that has dropped well below the threshold or tilted toward the door has moved too. That sends you to the settling questions below, not to a bag of patching compound.

What this page is, and what it isn't

This guide covers how concrete steps are built, why they fail and what fixes last, so you can judge any bid on its merits. If you want a second set of eyes, Plainfield Concrete Co. can give you a free look at the front walk and the flat concrete around your steps, which is often part of the same problem.
