Schaumburg grew fast. Most of the village was still farmland into the 1960s, and the split-levels, raised ranches, and colonials that filled in after that were built quickly to keep up with demand. Garages from that building boom are now fifty or sixty years old, and a lot of the original slabs were poured over whatever base was easiest to compact at the time, which wasn’t always much. It’s common for one of those slabs to develop a low spot near the door or a step where it meets the driveway.
We raise and level the garage floor that’s already there rather than breaking it out. That keeps the job faster, cheaper, and a lot less disruptive than a full replacement.
