Concrete Demolition Cost in Seattle: 2026 Pricing Guide
Last Updated: 5/3/2026If you are searching for concrete demolition cost in Seattle, you are usually deciding between fixing what you have or tearing it out and starting over. This guide walks through the price ranges Seattle homeowners and small commercial property owners typically see in 2026, the factors that move the bid up or down, and the questions to ask before signing. Pricing examples are presented as ranges — every site is different, and a written, on-site estimate is the only way to lock in real numbers.
What concrete demolition usually costs in Seattle
Most residential demolition jobs are quoted per square foot of slab, with separate line items for breakup, haul-off, and disposal. Light residential slabs (patios, walkways, four-inch driveways with light mesh) sit at the low end of the range. Heavy reinforced slabs, thicker driveways with rebar, and structural foundations sit at the high end. Tear-out cost is almost always lower than the cost of the new pour that follows it, so the demolition number is one piece of a larger project budget.
Pricing factors that move the bid
| Factor | Effect on price |
|---|---|
| Slab thickness | 4-inch slabs break up quickly; 6-inch+ commercial slabs add labor and equipment time. |
| Reinforcement | Heavy rebar or post-tensioned cable raises both demo time and disposal weight. |
| Site access | Open driveways are cheapest; backyards reachable only on foot can double labor hours. |
| Square footage | Larger jobs lower the per-square-foot rate due to mobilization efficiency. |
| Haul distance | Trips to the recycling facility or transfer station are billed by load. |
| Substrate prep | If the soil under the slab needs regrading or compaction after demo, that adds line items. |
What's typically included in a Seattle demolition quote
- Site protection: plywood over landscaping, plastic over siding, dust control during sawcut.
- Sawcutting: clean cuts on slab edges so adjacent concrete or asphalt isn't damaged.
- Breakup: jackhammer, breaker attachment, or hydraulic shears depending on slab and access.
- Haul-off: loading the broken concrete and trucking it off-site.
- Disposal or recycling: dump fees at a recycling yard or transfer station.
- Cleanup: removing dust and debris, leaving subgrade ready for the next phase.
If you are pairing demolition with a new pour, ask whether concrete demo and removal is bundled into the same contract — bundled jobs usually save on mobilization fees.
Pacific Northwest factors
Two local realities affect demo pricing in Seattle. First, glacial till under many older slabs makes regrading slower than open dirt — expect a base-prep line item if the new pour requires a level subgrade. Second, the wet season turns exposed soil to mud quickly, which delays haul-off and can pause work entirely. Most Seattle contractors schedule demo in dry windows when possible and use plywood mats for access during shoulder seasons. If your project is time-sensitive, plan demo for late spring through early fall.
How to compare demolition bids fairly
Three identical-looking quotes can have very different scopes. Before comparing prices, confirm each bid lists: slab area in square feet, slab thickness assumption, whether haul-off and dump fees are included, who owns the recycled concrete, and whether the contractor will sawcut the perimeter. A quote that omits sawcutting on a partial-slab demo will tear up your good concrete too.

Frequently asked questions
How much does concrete demolition cost in Seattle?
Most residential concrete demolition projects in Seattle fall in a per-square-foot range that scales with slab thickness, reinforcement, access, and disposal distance. Driveways, patios, and sidewalks are typically priced lower than reinforced foundations or thick commercial slabs. Always request a written, itemized bid that separates breakup, haul-off, and dump fees.
What factors increase concrete demolition pricing the most?
Slab thickness and rebar density are the biggest cost drivers, followed by access (can a skid steer or mini-excavator reach the slab), disposal distance, and whether the substrate underneath needs to be regraded. Tight backyards, stairs, and second-story decks raise labor hours significantly.
Is haul-off included in a concrete demolition quote?
Reputable Seattle demolition contractors include haul-off and dump fees in the bid, but it should be itemized. If a quote is unusually low, confirm whether disposal is included or billed separately. Concrete is heavy, so dump tickets add up quickly on larger jobs.
Do I need a permit to demolish a concrete slab in Seattle?
Most simple slab removals (patios, walkways, residential driveways not in the right-of-way) do not require a Seattle SDCI permit. Driveway approaches in the public right-of-way, retaining walls over four feet, and structural foundations typically do require permits or SDOT review. Confirm with your contractor before scheduling.
Can demolished concrete be recycled?
Yes. Most Seattle-area demolition contractors haul broken concrete to a recycling facility where it is crushed and reused as base material. Recycling is often cheaper than landfill disposal and reduces the embodied carbon of your project.
