Shed Demolition in Boise: What Do You Do With the Slab?
After shed demolition in Boise, that concrete slab is still sitting there. Here's when to break it out, when to keep it, and what removal actually costs.
A guy in Meridian called us last spring, pretty annoyed. He'd paid a crew to handle the shed demolition in his backyard, and they left a 10x12 concrete pad sitting in the middle of the lawn like a patio nobody asked for.
He figured the slab was part of the job. It wasn't. Nobody told him either way.
That's the thing about tearing down a shed around here. The building is the easy part. The slab underneath is where people get surprised, and it's worth deciding what you want before anybody swings a hammer.
Why the slab never comes up until demo day
Most sheds in the Treasure Valley sit on one of three things. A poured concrete pad, a bed of gravel with skids or blocks, or straight dirt with pressure-treated runners slowly rotting into it.
Gravel or skids? You're fine. Rake it out, throw down topsoil, plant grass, done.
Concrete's a different story. It's usually 3 to 4 inches thick, it's heavy, and hauling it costs real money because disposal is priced by weight.
So a lot of quotes quietly leave it out. Nobody notices until the shed's gone and the pad is staring at them.
Ask up front. Any crew worth hiring will tell you straight whether the slab is in the price.
Three things you can do with the slab
You've got options and none of them are wrong. It comes down to what that corner of the yard is going to become.
| Option | Rough cost | Makes sense when |
|---|---|---|
| Leave it in place | $0 | You're putting a new shed, hot tub, or patio there |
| Break it up and haul it out | $400–$900 | You want lawn, garden, or a tree in that spot |
| Break it up, bury it, cap with soil | Not worth it | Honestly, almost never |
That last one gets suggested a lot and we're not fans. Buried chunks settle unevenly, they work their way up and eat a mower blade, and if you ever sell the house it's an awkward thing to explain. Skip it.
Leaving the slab is a better call than people expect. Replacing an old wood shed with a new metal one? That pad is free foundation work. Pressure wash it, check the cracks, set the new building right on top.
What slab removal costs after shed demolition in Boise
For a standard backyard pad, figure $400 to $900 on top of the shed demolition itself. An 8x10 sits at the low end. A 12x16 with thickened edges or a footing lands at the top.
What moves the number? Access, mostly. If a machine can get to the backyard through a side gate, it's quick work. If everything comes out by hand through a 32-inch gate and down a narrow side yard, it takes longer and the price shows it.
Thickness matters too. Most shed pads are 3 to 4 inches with no rebar, and those break up fast. Some folks poured what was really a small garage slab and later called it a shed pad. Six inches with wire mesh is a different animal.
Here's the good part: clean concrete doesn't get buried. Outfits like Western Recycling crush it into road base, so disposal runs cheaper than mixed demo debris headed to the Ada County landfill. That savings lands in your quote.
Getting things ready before the crew shows up
There isn't much prep, but a few things genuinely help.
- Clear anything within about 8 feet of the pad, including planters, hoses, and the grill nobody's touched since 2022
- Point out sprinkler lines and low-voltage landscape wiring, since they're often run right along the slab edge
- Tell us about any electrical conduit feeding the shed, because older sheds in Nampa and Garden City often have a buried line that's still hot
That last one matters most. We've found more live wires under shed slabs than you'd think, usually a homeowner special from decades back with no conduit at all. If you know it's down there, say so and we'll kill it at the panel first.
And empty the shed before demo day. We wrote up how to clear out a shed before demolition because it's the single biggest thing that slows a job down. Idaho Youth Ranch will take the usable stuff, and that beats paying us to haul off something somebody else wanted.
Permits for shed demolition and slab work
Pulling a slab on its own usually doesn't require a permit. The shed might, depending on size and whether it had power or was attached to anything else.
We covered that in our post on shed demolition permits in Boise, and the rules shift a little between Boise, Meridian, and unincorporated Ada County.
One thing that does matter: if the shed had a subpanel, that disconnect needs to be handled right. Not a big deal, just not something to freestyle on a Saturday.
The bottom line
Decide about the slab before the shed comes down, not after. Reusing it is smart if something's going back in that spot. Pulling it is worth the $400 to $900 if you want that corner to be yard again.
Either way, get it written on the quote so there's no 10x12 surprise waiting for you.
