Garage Floor Leveling in West Michigan
A garage floor that's settled — near the doorway, along the back wall, or at the transition between the floor and the apron — is one of the most common calls we get. Settlement at the garage entry creates a ramp effect that catches tires and strains door seals. Separation at the back wall or around floor drains signals voids beneath the slab.
We lift and level settled garage floors across Grand Rapids, Wyoming, Kentwood, Walker, Grandville, and the rest of West Michigan. Most garage floor jobs are done in a morning without any heavy equipment, demo, or new concrete trucks.

How Garage Floors Settle
Most garages are built on a floating slab — a concrete floor poured over compacted fill that sits independent of the foundation footings. Over time, that fill settles or erodes, and the slab follows.
In West Michigan, the most common culprits are:
Soil compaction. Fill beneath a garage is never perfectly uniform. Over 10–20 years, areas compact at different rates, and the concrete above drops with them. You'll see it as a low spot or a tilt — often toward the doorway or toward the corner farthest from the apron.
Water intrusion. Water infiltrating beneath the slab from outside — through the apron joint, around the walls, or from grading that directs runoff toward the garage — erodes fine particles from the sandy soils common in Kent and Ottawa counties. Voids open up, and the slab drops.
Freeze-thaw at the apron joint. The joint between the garage floor and the exterior apron is a natural entry point for moisture. When water infiltrates and freezes, it can displace the slab. Over many cycles, the apron and the interior floor end up out of plane — the classic "hump at the garage door" problem.
What We Can Fix
Settled garage floor interior — sections of the slab that have dropped away from their original position. We inject material beneath the low areas and push the slab back up.
Separation at the house wall — when the slab has pulled away from the stem wall, leaving a gap that grows over time. We can fill the void and restabilize the slab.
Apron-to-floor transition — when the exterior apron has settled or when the interior slab has risen relative to the apron, creating a ridge. We can level the transition point.
Floor drain areas — settlement around floor drains is common because the drain creates a natural path for water to move beneath the slab. We can lift the area around it without compromising the drain.
What Garage Floor Leveling Costs
Most garage floor leveling jobs in West Michigan run $600–$2,500, depending on how many sections have settled and how much void space needs to be filled.
Replacing a garage floor — breaking out the existing slab, hauling debris, forming, and pouring new concrete — runs $6–$10 per square foot or more for a typical two-car garage (400–500 sq ft). That's $2,400–$5,000 minimum, and usually more by the time labor and disposal are included. Leveling the same slab typically costs a third of that.
