Concrete Repair & Leveling for Kent 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.
Mid-century homes downtown and on Scenic Hill, many 1970s through 2000s subdivisions on East Hill, and new homes and townhomes. We work across East Hill, West Hill, Panther Lake, Meridian, Lake Meridian, Scenic Hill, the Kent Valley and downtown.
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.
Kent conditions that affect your repair
Soil and settling
The Kent Valley is the old Green River floodplain, with softer river soils and a high water table in many areas. Slabs there need a solid compacted base and drainage that keeps water from sitting underneath.
Tree roots
Street trees and large firs in older East Hill neighborhoods are a common cause of lifted walks and cracked driveway edges.
Rain and drainage
Standing water on valley lots and runoff on hill lots are the two main ways concrete fails here. Slope and drains are planned on every job.

Permits for concrete repair and leveling in Kent
Most repairs on private property don’t need a permit, but repairs to the public sidewalk, curb or driveway approach are right-of-way work. Kent handles street use and right-of-way work through its Engineering permits, so driveway approaches, curbs and sidewalks along the street are permitted through the City. Kent’s Permit Center makes the call for your property, and we’ll tell you what we expect before you commit.

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 Kent property. We give a written quote after we understand the job.
Concrete Repair & Leveling in Kent: 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 Kent?
Ground-level flatwork on private property is often exempt, while retaining walls over 4 ft from the bottom of the footing and work in the right-of-way need permits. Kent’s Permit Center processes permits online and can confirm for your address.
