The slab isn't broken. The dirt under it gave way.
Your car sits at a lean. A ball or a wrench rolls toward one corner and won't stop. The slab dropped on that side because the soil under it washed out or compacted.
A gap under the rubber bottom seal where water, leaves, or critters get in. The door is fine — the floor dropped away from the door track.
A step or lip between the driveway apron and the garage floor. A quarter inch is enough to catch your foot, jam a wheelbarrow, or stop a motorcycle wheel.
A crack across the floor with one side lower than the other. As long as the slab is still in one piece, both halves can be lifted back to level. Concrete crack repair closes wider gaps that won't lift back together.
Garage floor leveling lifts a sunken garage slab back to grade without tearing it out. We drill small holes through the slab, inject expanding foam or cement-based mud underneath, and the floor rises back to level. Most jobs take two to four hours. You drive on it the same day.
Most garage floors don't need full replacement. If the slab is still in one piece, it can be lifted. A full 2-car garage replacement runs $4,000 to $8,000. A foam lift on the same slab usually runs $1,500 to $4,000 — about 50 to 75 percent less. We tell you straight which one your slab needs.
One dipped corner or one settled section of the bay. We target the void with foam, lift just that section back flush, and patch the holes.
The whole 1- or 2-car bay has dropped, usually pulling away from the back wall. We grid injection points across the floor and lift the slab evenly back to grade.
The apron in front of the garage door has settled and left a step or trip lip. We lift the apron back flush with the garage slab so the door seals and wheels roll over clean. Driveway leveling covers the section just outside the apron.
The Process
We come out and measure the dip with a level. We trace the cause — usually a downspout, a clay soil cycle, or compaction under where you park. You get a flat written price before we drill.
Small holes go through the slab in a grid across the dipped section. Foam holes are the size of a dime. Most garage jobs need four to eight holes total.
Foam expands underneath and lifts the slab in controlled bursts. We watch with a laser the whole time so the floor comes up flush and the garage door seals again at the bottom.
We seal the holes with non-shrink patch and clean up. Foam cures in about 15 minutes. You can park your car back inside the same day.
We give you the price before we drill the first hole. Whatever number we quote is the number you pay. No change orders mid-job, no surprise charges after the slab is up.
We use both foam and mud, and we tell you which one fits your garage. Foam lasts 20+ years, won't wash out from snowmelt or hose-downs, and you drive on it the same day. Mud is cheaper and good for 2 to 5 years. We lay it out — your call.
Most garage floor lifts are done in a half day. The slab is drivable about an hour after we finish. No tear-out, no week of waiting on new concrete to cure, no losing your garage to a contractor for three days.
Most garage floor lifts run $700 to $4,000. A single dipped section is usually $700 to $1,500. A full 2-car bay runs $1,500 to $4,000 with foam, or $1,250 to $2,700 with mudjacking. Replacement runs $4,000 to $8,000 — leveling saves about 50 to 75 percent.
Foam injection lasts 20 years or more because it's waterproof and won't wash out under snowmelt or wash water. Mudjacking lasts 2 to 5 years on average. The lift only holds long-term if the soil cause — usually a downspout or drainage issue — also gets fixed.
Yes, in most cases. As long as the slab is still in one piece, it can be lifted back to grade with foam or mud injection. Replacement is only needed when the slab is broken into pieces, has settled more than 2 inches, or has cracks across more than a third of the floor.
Most garage floor jobs are done in 2 to 4 hours. A single section takes about an hour. A full 2-car bay runs 3 to 5 hours. Foam cures in 15 minutes — you can drive on it the same day. Mudjacking jobs need 24 to 72 hours before vehicles go back on.
The soil under the slab fails. Common causes are downspouts dumping water that washes out the dirt at the corner, clay soil shrinking in dry months, the same parking spot getting loaded by the car for years, and poor compaction when the floor was first poured.
