Garage floor repair across San Diego County

Rigid epoxy fill will not stop an active crack from growing if the slab continues to move. Semi-rigid polyurea joint filler is the correct material for active cracks because it accommodates minor movement without cracking again. Hairline cracks that are stable and not expected to move can be filled with rigid epoxy mortar. The crews we refer assess which type of crack is present before selecting the fill material.

Yes, but the cracks must be addressed first. Coating over an unrepaired crack telegraphs the crack through the epoxy within months and produces a visible line in the floor that gets worse over time. Repaired and leveled cracks can be coated over and will not show through a properly applied epoxy system.

Concrete shrinkage during curing is the most common cause of garage floor cracking. Soil settlement and expansion cycles, particularly in East County clay soils, cause cracking over time. Tree roots, inadequate slab thickness, and poor subbase preparation are contributing factors. Coastal slabs with high moisture content experience more movement than dry inland slabs. Most residential garage floor cracks are cosmetic and do not indicate structural failure.

Crack and spall repair before coating typically runs $200-$800 on a standard two-car garage depending on the number and severity of cracks, the depth of any spalling, and the repair materials required. When repair is part of a full coating project, the cost is usually included or bundled into the total system quote. Your coating crew identifies repair needs at the on-site estimate before any price is committed.

Yes. Crack repair and slab grinding require full access to the entire floor. Vehicles, stored items, and anything on or near the floor need to be out of the garage before the crew arrives. The crews we refer are typically on-site for a full day when prep and repair are combined, so the garage should be completely clear before the scheduled start time.
