When doing it yourself wins
A small resin or metal kit shed on a paver base is a fair weekend job. Panels unclip or unscrew, the floor lifts, and the whole thing fits in a couple of pickup runs. If you own the tools, have a helper, and the shed is empty, you'll save money. The trade is your Saturday and the trips. Keep the pieces small enough to handle and call Sunshine 811 before you pull any anchors near buried lines.
When hiring demolition and haul-away wins
Hire it out when any of these are true: the shed is wood and rotted, there's a concrete pad you want gone, the shed is still full, or you don't own a truck. Rob's crew clears the contents, takes the structure down, loads the pieces as they come off, and rakes the footprint. Most sheds land at a half trailer, $350, or a full, $700, and the number is set from photos before the crew comes. The slab is a separate line because concrete never rides in the trailer; the skid steer breaks it and partner dump trucks haul it, quoted per job.
Two questions to ask before either one
Permits: ask your city or the Polk County building department whether your shed needs one to come down. Rules differ between the cities and unincorporated county. When a job needs a permit, Rob works with a general contractor and tells you so up front.
Siding: if the shed went up before 1980 and you're not sure what the siding or paint is, ask about testing before anyone cuts it. That check isn't a hauler's job, and it's cheaper than finding out later.
