Concrete and Driveway Contractors in Washington
Driveways, patios, walkways and repair — connected with a licensed contractor who prepares the base properly, because that is what determines whether it lasts.

Concrete work covers driveways, patios, walkways, steps, slabs and repair or replacement of deteriorated surfaces. Longevity is determined by base preparation, drainage, correct thickness and proper curing — all largely invisible once the pour is finished.
Concrete is unforgiving of poor preparation, and the failures appear years later when nobody is inclined to connect them back to what happened before the pour.
Most cracking is normal. Concrete shrinks as it cures and moves with temperature, which is why control joints exist — they encourage cracking to happen in a planned straight line rather than randomly. Fine cracks following those joints are doing their job.
What matters is cracking that indicates movement underneath: wide cracks, cracks where one side has lifted relative to the other, and cracking that is actively progressing. Those point at the base rather than at the concrete.
The two halves of the state deteriorate differently. In Spokane, Yakima and the Tri-Cities, freeze-thaw cycling is dominant — water enters surface pores and small cracks, freezes, expands and widens them, and each winter compounds the last. West of the Cascades, freeze-thaw is minor and the problems come from water and inadequate base preparation.

Repair or replace
Surface problems can sometimes be resurfaced. Movement beneath the slab cannot.
| Situation | Usually repair | Usually replace |
|---|---|---|
| Fine surface crazing | Yes — largely cosmetic | No |
| Cracks along control joints | Yes — working as designed | No |
| Surface spalling on sound slab | Resurfacing may work | If widespread and progressing |
| Wide cracks with displacement | No | Yes — indicates movement beneath |
| Settlement or sinking sections | No | Yes, after addressing the cause |
| Frost-heaved sections | No | Yes, with deeper footings east of the Cascades |
Where settlement is involved, the cause has to be addressed first. New concrete poured over the same unstable base does exactly the same thing again.
What drives the cost
Area is the obvious variable. Everything that determines whether it lasts is underneath.
Area and thickness
A driveway carrying vehicles needs more thickness and reinforcement than a patio.
Base preparation
Excavation, base material and compaction. Invisible once poured and the single biggest determinant of longevity.
Removal of existing concrete
Breaking out and disposing of an existing slab is substantial work by itself.
Drainage and grading
Water must run off and away rather than pooling on the surface or collecting beneath.
Mix specification
East of the Cascades, concrete needs appropriate specification for freeze-thaw exposure.
Finish and sealing
Surface finish options vary, and sealing reduces water absorption where freeze-thaw applies.
East of the Cascades, ask specifically what mix specification is being used for freeze-thaw conditions and whether sealing is recommended. A contractor who cannot answer that clearly is quoting Western Washington work.

Almost everything that determines the outcome happens before the concrete arrives.
What a good contractor will do
- Hold an active L&I contractor registration, bond and insurance
- Specify base preparation depth, material and compaction
- Confirm thickness and reinforcement appropriate to the load
- Set control joints at correct spacing and cut them at the right time
- Explain the curing approach rather than leaving it to chance
Warning signs
- Quoting a price per area with no base preparation detail
- No mention of control joints or curing
- Pouring over an existing slab without assessing it
- Using Western Washington mix specification east of the Cascades
- Replacing settled concrete without addressing why it settled
Curing is invisible, affects strength permanently, and is the easiest corner to cut. A contractor who explains their curing approach unprompted is worth taking seriously.

Concrete & Driveways FAQs
Not necessarily. Concrete shrinks and moves, and cracking along control joints is exactly what those joints are for. What matters is wide cracks, cracks where one side has lifted relative to the other, and cracking that is actively progressing — those indicate movement beneath the slab.
Freeze-thaw cycling. Water enters surface pores and small cracks, freezes, expands and widens them, and each winter compounds the last. Spalling accelerates once started because the damaged surface holds more water. De-icing salts make it considerably worse.
Base preparation more than anything — properly compacted, adequate depth, correctly graded. That work is invisible once poured, which is why it gets skimped. Drainage, appropriate thickness, correct control joints and proper curing complete the picture.
Sometimes, depending on the cause and the extent. Where a slab has settled because of what is beneath it, lifting without addressing the underlying issue is temporary. Have the cause established before choosing between lifting, replacing or leaving it.
East of the Cascades it helps meaningfully, by reducing water absorption and therefore freeze-thaw damage. West of the Cascades the case is weaker since freeze-thaw is a minor factor there. Ask a contractor familiar with your side of the state.
They accelerate freeze-thaw damage considerably, which matters in Spokane, Yakima and the Tri-Cities. If you care about the surface, it is worth knowing that before making salt part of your winter routine.
