Concrete steps can pull away from a house when the ground under them settles, washes out or moves with freezing and thawing, or when the steps were not supported or connected the way the site required. The actual cause varies, so the steps and the conditions around them need to be looked at together.
A growing gap between the steps and the house is a common concern, especially on older homes. It can let water in and create a trip hazard at the door.
Possible Contributing Factors
Steps often sit on soil that was backfilled after the house foundation was built. That soil can compress over time, which may let the steps sink or tip away from the house.
Water can play a role too. Downspouts, roof runoff and grading that sends water toward the steps can soften or wash out soil. In Michigan, freezing and thawing can also move the ground under outdoor concrete.
How the steps were built, including their support and how they meet the house, can affect how they respond to these conditions.
These are possibilities, not a diagnosis. A gap or crack alone does not prove which factor is involved.
Why the Gap Matters
A gap at the top step can catch a foot, especially when entering or leaving with full hands. Water and snowmelt can also run into the gap and toward the foundation, which may add to moisture problems.
If the steps keep moving, the gap may grow and the treads may begin to tilt, making them harder to use safely.
Gaps can also let insects or debris collect against the house, which is another reason to keep an eye on them.
What an Evaluation Looks At
A contractor may check how much the steps have moved, whether they are still shifting, whether they rock or tilt, the condition of the concrete and how water drains around them. Changes over time are useful information, so noting the gap size by season can help.
Depending on what is found, options may include sealing the gap, concrete leveling for some step units, repair or replacing the steps with improved support and drainage.
What to Avoid
Avoid packing the gap with materials that trap water or trying to pry or lift the steps. Lifting heavy concrete steps is not a DIY task and can cause injury or more damage.
In the meantime, keeping downspouts directed away and clearing snow and ice promptly can help limit further problems.
If the gap is near a door, it is also worth checking whether water has been getting inside around the threshold.
If your steps are separating from the house, an on-site evaluation can help determine what may be causing it and what options fit. Learn more about our concrete steps services in Kalamazoo, or call (269) 404-2457.
