Concrete Repair & Leveling for Federal Way properties
Not every cracked slab needs to come out. The honest answer depends on what caused the damage and whether it’s still happening. A hairline crack in a stable slab is cosmetic. A panel that has sunk an inch but is still in one piece can often be lifted. A slab that’s breaking into pieces over a soft, wet base is usually cheaper to replace than to keep patching.
1960s through 1990s houses across the city, plus newer homes and townhomes near the city center. We work across Twin Lakes, Dash Point, Steel Lake, Mirror Lake, Lakota, Star Lake, Camelot, Northshore and West Campus.
Crack repair
Cleaning and sealing stable cracks so water stays out.
Slab lifting
Raising sunken panels with mudjacking or polyurethane foam.
Trip hazards
Grinding or lifting offsets on walks and patios.
Federal Way conditions that affect your repair
Soil and settling
Glacial soils are common, with wetter ground near the city’s many lakes and wetlands.
Tree roots
Big firs and cedars are common on Federal Way lots, and their roots lift walks and driveway edges.
Rain and drainage
Rain and moss are the main enemies of shaded flatwork here. Slope, finish texture and sealer choice all matter.

Typical market ranges, not a quote from Seattle Concrete Contractors. These are ranges other Seattle-area concrete contractors publish for this work (Seattle Concrete (seattleconcrete.com) service pages; per-area leveling from Seattle Foundation Repair Pros, checked November 2026). Your price depends on size, access, removal, base work, finish and permits, and on conditions at your Federal Way property. We give a written quote after we understand the job.
Concrete Repair & Leveling in Federal Way: quick answers
Should I repair or replace my concrete?
If the slab is mostly whole and the cause is fixed, repair usually makes sense. If it’s breaking up everywhere or the base has failed, replacement is better value.
Mudjacking or foam: which is better?
Both lift slabs. Foam is lighter and cures faster; mudjacking is usually cheaper. Soil and slab condition decide.
Will cracks come back?
Sealed cracks can reopen if the slab keeps moving. That’s why we look for the cause.
Do I need a permit for concrete work in Federal Way?
Ground-level patios and walks are often exempt, but retaining walls over 4 ft from the bottom of the footing, work near steep slopes or water, and right-of-way work usually need permits. Federal Way’s Permit Center can confirm for your address.
