Garage floors look simple on paper: a rectangle indoors. In practice they’re precision work. The slab has to hit grade against an existing foundation, slope toward the door, and finish flat enough that the customer doesn’t notice it ever again. Quote accordingly.
What sets garage floors apart
- Thickness. Vehicles live here. 5 to 6 inches is typical, and that extra depth over a patio pour means more yards for the same footprint.
- The pour is boxed in. Walls on three sides changes how you place and screed. Pump or buggy access can add cost the square footage won’t show.
- Slope and drains. Water comes in on the car. It needs a path back out, either to the door or a drain. Getting that fall right is skilled screed work.
- Finish. Garage floors usually take a hard trowel finish. If the customer is talking epoxy later, the finish spec gets tighter.
Example math
A standard two-car garage runs around 20 by 20, which is 400 square feet. At the example rate of $9 per square foot that’s $3,600 before tear-out or prep. Replacing an existing cracked floor adds demo inside a structure, which is its own line item, and the example tear-out rate of $4 per square foot is the right ballpark to start the conversation. The full method, from thickness to grade against the foundation, is in how to price a garage floor.
