What to know about concrete repair and leveling in Seattle
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.
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.
Resurfacing
Overlays for scaling, spalling or worn surfaces on sound slabs.
Panel replacement
Saw-cutting out broken panels and repouring.
Step repair
Patching edges, or rebuilding steps that pulled away from the house.
Options to talk through
| Problem | Usually means | Typical fix |
|---|---|---|
| Hairline cracks, no height change | Shrinkage; cosmetic | Clean and seal |
| One or two sunken panels on an intact slab | Base settled under that panel | Lift with mudjacking or foam |
| Scaling, spalling or a worn finish | Surface damage on a sound slab | Resurfacing overlay |
| Broken, heaved or rocking panels | Base failure or roots | Saw-cut and replace panels |
| Whole slab breaking up | Thin slab or failed base | Full replacement |
How Seattle’s ground and weather affect concrete repair and leveling
Water under slabs
Downspouts and poor slope wash out the base under patios and walks. Fixing the water stops it happening again.
Tree roots
Street and yard trees lift panels. Lifting won’t help; the panel and sometimes the root have to be dealt with, within tree rules.
Freeze-thaw and de-icer
Occasional freezes and salt cause scaling on older concrete. Sealing helps; badly scaled surfaces need resurfacing.
Soft soils
Areas with fill or wet soils keep settling; lifting may be temporary there.
Sidewalk offsets
Trip hazards in a Seattle sidewalk are right-of-way work that goes through SDOT.
Color match
New concrete won’t match old exactly. We plan replacements at joints so the change looks intentional.

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. We give a written quote after we understand the job.
What affects the price
These are the things that move a quote most, in roughly the order they matter.
Cause
Fixing the cause (water, roots) adds work but saves money later.
Size
Small jobs carry a minimum.
Method
Foam costs more than mudjacking but is lighter and quicker.
Access
Tight spots or steps take longer.
Matching
Replacing panels on a stamped or colored slab is harder to blend.
Permits
Sidewalk repair needs right-of-way permits.
What a good written quote should include
Whoever you hire, ask for these in writing. They’re what separate a slab that lasts from one that cracks in two winters.
Scope and size
The area, thickness and shape, so you can compare quotes on the same job.
Base and drainage
How deep the excavation goes, how much gravel, and where water goes.
Reinforcement and joints
Rebar or mesh, dowels into existing concrete, and joint spacing.
Finish and sealing
The finish, whether it’s sealed, and what upkeep to expect.
Removal and cleanup
Demolition, haul-away and site restoration.
Permits and schedule
Which permits apply, who pulls them, and cure time before use.
Concrete Repair & Leveling: common questions
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.
Can you fix a trip hazard in my sidewalk?
Yes. In Seattle, sidewalk work is right-of-way work with an SDOT permit, and offsets can sometimes be ground down instead of replaced.
Can you repair stamped concrete?
Small repairs and resealing, yes. Matching pattern and color on replaced sections is difficult; expect some difference.
Is repair a permanent fix?
It can be if the cause is solved. Lifting on soil that keeps settling may need repeating.
