Precision Floor Flattening & Leveling
Modern flooring systems—especially large-format tile, rigid LVP, and engineered wood—require incredibly flat surfaces to lock together properly. If a subfloor dips or peaks by more than 3/16ths of an inch over a 10-foot span, the final installation will crack, creak, or pull apart.
Los Angeles's varying typography, seismic activity, and century-old housing stock means uneven floors are virtually guaranteed. Our teams use high-tech laser mapping to find the microscopic dips and ridges running through your room.
We deploy liquid self-leveling concrete compounds over slabs to create glass-smooth profiles, or utilize wood shims and sleeper systems over timber frames to flatten out the sag in historic homes. Perfect flats, every time.
Floor Leveling Strategy Costs
| Material | Price/sqft | Best For | Lifespan |
|---|---|---|---|
| Concrete Self-Leveling Compound | $2–$4/sqft | Basements, Garage conversions | Permanent |
| Plywood Overlay & Shims | $3–$6/sqft | Historic homes, Second floors | Permanent |
| Major Structural Joist Adjustment | $5–$12/sqft | Foundational sinking repair | Permanent |
Self-leveling prices vary drastically by the 'depth' of the pour required to fill the room's lowest point.

Leveling Method Guide
Self-Leveling Compound
We pour a liquid, highly viscous cement mixture over concrete slabs. It uses gravity to hunt down the lowest points, pooling until the entire room is glass-flat and perfectly even.
Plywood Overlay & Shims
For historic homes with aged joists that sag in the middle of the room, we shoot a perfectly level laser line across the perimeter and slide microscopic cedar shims under thick layers of plywood until the new false-floor is completely flat.
Joist Adjustment
If the floor is severely pitched (slanted like a ramp), leveling it requires opening the frame and physically planing down high joists or jacking and sistering low joists. This is intense but permanent structural work.
