Sizing a dumpster for a demo job

Every demo job is a debris job. The swinging takes a day; the carrying takes the rest. And the single most common way a demo schedule falls apart is a container that's the wrong size, delivered on the wrong day.

Here's how to think about it properly.

Volume is the obvious number. Weight is the one that gets you.

A dumpster has two limits: how much fits, and how much it's allowed to carry. Most rentals include a weight allowance, and material over that allowance is billed by the ton at the scale rate. That's standard across the industry, not a gimmick.

For household junk — furniture, boxes, clothing, general clutter — you'll fill a bin by volume long before you approach the weight limit. Demo debris is the opposite. Tile, mortar bed, plaster, brick, concrete, and roofing are dense enough that you can hit the weight allowance with the bin looking half empty.

So the real question isn't "how big is my kitchen." It's "what material is coming out of it."

Light and bulky vs. dense and heavy

Light and bulky — fills the bin fast, weighs little:

• Carpet and pad
• Cabinets and casework
• Drywall (bulky, surprisingly light per sheet)
• Suspended ceiling grid and tile
• Insulation, trim, doors, and framing lumber

Dense and heavy — barely takes up room, eats the allowance:

• Ceramic, porcelain, and stone tile
• Mortar bed and thinset
• Plaster and lath
• Cast-iron tubs and old sinks
• Concrete, brick, and stone
• Roofing shingles
• Dirt, sod, and anything wet

A job that's mostly cabinets and carpet needs volume. A job that's mostly tile and plaster needs weight headroom. Most real jobs are a mix, which is exactly why "what size for a kitchen" has no honest single answer.

The three sizes that actually fit a driveway

Our sibling line, Frontier Dumpster Bins, runs three compact sizes, all dropped off a no-CDL trailer rather than a semi so they fit where you park:

• 5 yd Compact — 8 ft × 4 ft × 4 ft, roughly two pickup-truck loads. One room, a small tear-out, a bathroom.
• 10 yd Standard — 10 ft × 5 ft × 5 ft, roughly three to four truckloads. A kitchen, a bath plus flooring, a whole-room strip-out. This is where most demo jobs land.
• 15 yd Large — 12 ft × 6 ft × 6 ft, roughly five to six truckloads. A multi-room gut, a full-floor strip-out, a commercial suite.

There's no 20, 30, or 40 yard in the lineup on purpose. Those need a semi to place, they don't fit a residential driveway, and they'll crack your concrete on the way in.

Rough reads by job type

These are honest ranges, not promises — the material always decides.

A bathroom. Small footprint, heavy contents. A cast-iron tub or a mortar-bed shower pan plus wall tile is a lot of weight from a tiny room. Often a 5, but a tile-heavy bath can justify a 10 for the weight headroom alone.

A kitchen. Cabinets and counters are bulky, backsplash and flooring add density, and the appliances add both. Usually a 10. A large kitchen with tile floor and a mud bed can push toward the 15.

Flooring only. Carpet across a whole house is pure volume — bulky, light, fills fast. Tile across the same square footage is the reverse. Same rooms, completely different container decision.

Drywall or ceilings. Bulky and light, so volume rules. Plaster over lath in an older post-1978 building flips that entirely — it's heavy and dusty and will surprise you.

A commercial suite. Ceiling grid and tile, carpet or VCT, partitions, and millwork. High volume, moderate weight, and usually more than one bin — which is why swap-outs matter more than picking a single perfect size.

Four rules that save money

1. Size up when you're between. A second haul costs more than the extra capacity. This is the cheapest insurance in the whole project.

2. Say what's going in before you book. A quote based on "a kitchen" is a guess. A quote based on "a kitchen with 200 square feet of mud-set tile" is a number that holds. Nobody likes a tonnage surprise, including us.

3. Plan for the swap, not just the drop. On a gut, the bin will fill mid-job. The question is whether swapping it is a dispatch decision or a phone call to a stranger. If the container and the crew come from the same company, the crew never stands still.

4. Keep it on private property. Nearly every Front Range city requires a right-of-way permit for a container set in the street, and almost none require anything for one sitting on your own driveway or pad. The compact sizes exist partly for that reason. Check your city's rule on its service-area page.

What can't go in

Some of this is regulated and worth being blunt about.

Asbestos-containing material does not go in a general demolition bin. If suspect material is present above Colorado's trigger levels — 32 square feet, 50 linear feet, or a 55-gallon drum equivalent in a single-family home — it gets inspected by a certified Asbestos Building Inspector and, if positive, abated by a Colorado-certified General Abatement Contractor and disposed of through that regulated channel. Colorado also prohibits recycling concrete or wood that's bonded to or contaminated with asbestos-containing material.

Paint, solvents, fuels, batteries, and electronics all have their own disposal paths. Appliances containing refrigerant need it recovered first. Tires and some treated materials are restricted at most facilities.

Or just let it be somebody else's problem

If we're doing the demolition, the sizing question disappears. We already know what's coming out of the space because we scoped it, the bin is ours, it lands when the crew lands, it gets swapped when it fills, and it goes on one invoice with the labor. That's the haul-away side of the business, and it's the whole reason this brand exists alongside the bins.

Doing the demo yourself and just need the container? Frontier Dumpster Bins rents all three sizes and books online.
