Before a new build can go vertical, whatever's standing on the lot has to come down first. Our demolition services take the structure down, clear the debris off-site, and hand you a site that's ready for the next phase. GCs and developers across the Greater Seattle area bring Mighty Arm in for one reason: the crew that drops the building is the same crew that grades the ground underneath it.
Mighty Arm works as the demolition sub on new residential and commercial developments, from commercial parcels and multi-home sites to single custom-home lots. Site clearing and demolition both sit under Division 31, and we run them as one continuous scope: take the structure down, pull the foundation, haul it out, and rough the site toward grade.
Because the teardown and the earthwork sit under the same crew, you're not scheduling a demolition sub, waiting for them to clear out, then bringing in a separate excavator to deal with what got left behind. We coordinate straight with your GC, engineers, and the utility locates, so the lot moves from standing structure to workable ground on one timeline.
Structure teardown, foundation removal, and debris hauling handled as a single scope
Site cleared and roughed toward grade under Division 31, ready for the earthwork phase
Direct coordination with GCs, developers, and utility locators before anything comes down
Abandoned septic systems decommissioned as part of clearing the site for redevelopment
The work covers commercial buildings, houses, and outbuildings on sites headed for redevelopment. Whatever's standing, we bring it down in order, break out what sits below grade, old foundations, slabs, and abandoned septic systems, and load it out, so nothing's buried for the next phase to hit.
Two of those teardowns run as their own service, each with a dedicated page covering what a homeowner or builder needs to know:
Most demolition delays don't come from the teardown itself. They come from a lot that got cleared but not finished, so the next crew shows up to debris, a half-pulled foundation, or ground nobody graded. Mighty Arm's demolition services are built to hand off cleaner than that.
Track Record
Projects completed for general contractors and developers across the Greater Seattle area.
We don't stop at a bare lot. The ground gets roughed toward grade so the next phase starts on workable footing, not a debris field.
Clear updates from the first walk to final haul-off. It's what the GCs we work for tell us keeps them calling back.
We load out and haul off what we take down, so the lot comes back clean and ready for the next trade.
Prevailing-wage public and federal work, with the documentation most contractors would rather not take on.
Every teardown moves through the same four steps, so you always know what's done and what's next.
SEE OUR FULL PROCESS
We go over what's coming down, walk the site, confirm what has to stay, and settle on the approach before a machine shows up.
We review the plans and existing conditions, check access and utility disconnects, coordinate with your GC or engineer, then send back a proposal with a defined scope, price, and schedule.
Once you approve it, we handle the contract and any permits the job calls for, confirm utilities are disconnected, then mobilize and bring the structure down in order.
We clear the debris, rough the lot toward grade, walk it with you or the GC, and turn over ground that's ready for the next phase.
A teardown's easy to bid and easy to walk away from. What matters is whether the GC hands you the next lot too. Here's what the contractors and developers we work with have to say.
From 220+ Google reviews
The gap most GCs hit is between demolition and excavation. One sub tears the structure down and leaves, another shows up weeks later to deal with the ground. Running both under one crew closes that gap, and it's the core of how we scope our demolition services.
For a developer, that's fewer subs to line up and one fewer seam where the schedule can slip.
Plenty of outfits will bid a teardown. What matters on a development site is whether the demolition contractor shows up when they said, works clean, and leaves the lot the way the next phase needs it.
Those are the things a GC remembers when the next lot needs clearing.
A teardown produces a lot of material, and handling it is part of the scope. Demolition and debris removal come together with us, so a dropped structure doesn't become someone else's pile to deal with.
One number covers the teardown, the haul-off, and the cleanup.
There's no flat rate for a teardown, and any demolition services priced off a rate sheet before anyone's seen the site should make you nervous. Every bid we write comes from the structure and the lot in front of us.
Send us the address and the scope, we'll walk it, then put a real number and a schedule in writing. No allowances that balloon at billing.
Mighty Arm rolls crews and equipment to sites within a 50 to 70 mile radius of Seattle, reaching Tacoma to the south, Bellingham to the north, and North Bend to the east. If there's a structure to bring down inside that range, we can get to it.

Home base & primary coverage
What GCs and developers most often ask before handing us a demolition scope.
We take down structures on development sites, houses, outbuildings, and light commercial buildings, then pull foundations, haul the debris, and rough the lot toward grade. On a residential lot or a commercial parcel, the scope runs from the teardown through a cleared, workable site.
Both. We take down single-family homes and outbuildings for redevelopment, and we handle commercial structures on development parcels. The teardown approach scales to what's on the lot.
We do. When a redevelopment site has an old or abandoned septic system, we decommission it while clearing the lot, so there's nothing left below grade for the new build to work around. We confirm the permit and inspection requirements for the local jurisdiction during the proposal.
Either one. A lot of GCs have us clear the structure and then rough and grade the site, since we run the earthwork too. If you only need the building down and hauled, we'll bid just that.
We haul it off. Debris gets loaded out as the teardown moves and taken off-site for disposal, so you're left with a clean lot instead of a pile to deal with.
We pull the permits a teardown requires when that's part of our scope, and we coordinate the utility disconnects that have to happen before anything comes down. We confirm who's handling what during the proposal.
It depends on the structure, the site, disposal, and permitting. A single outbuilding can be quick; a house with a full foundation pull and haul-off runs longer; a commercial structure longer still. We lay out a schedule in the proposal so you can plan the phases behind it.
We do. Mighty Arm is SAM.gov registered and handles prevailing-wage public and federal work, including the added documentation those jobs carry, which is more than many contractors want to take on.
We warrant our workmanship for one year from substantial completion. The warranty excludes damage caused by others, settlement beyond normal tolerances, misuse, or changes in site use.
Send us the site address and a rundown of what's coming down, and we'll walk it and put together a scope, price, and schedule specific to the job.
Give us the basics and a quick description of the structure and scope. We'll take it from there.
