If you're comparing Remodeling Debris Removal to a standard dumpster rental, start here. It is a steady mixed stream from one room at a time rather than a single demolition burst. Bring this up yourself if the hauler doesn't: tile, plaster and mortar are far denser than the cabinetry and drywall they arrive with.
Two ceilings apply to every load: how much fits, and how much is allowed to weigh. Dirt and concrete hit the second one first; furniture and boxes usually hit the first. When homeowners and remodelers call in this kind of job, the debris volume is usually easy to anticipate in advance, so the containers that get dispatched tend to land in the 15 or 20 yard bracket. What decides the call quickly: the width of the path a truck needs, and whether the container sits on sidewalk that needs protecting.
A whole-house cleanout combines light junk with the occasional heavy piece, so plan around whichever runs out first, the space or the weight allowance, since either one can end the load early. Nail down what counts as a prohibited item on this particular order. The list varies by hauler, and a mattress or freezer left on top can stall the whole pickup. Ordering slightly larger than you think you need costs less trouble than a second pickup for the overflow, so when in doubt, size up rather than risk a return trip.
