What Size Dumpster Do I Need in Columbia, SC? The Midlands Sizing Guide

The question arrives twenty times a week, always the same way: "I'm redoing the kitchen, what size do I need?" Nobody can size a container off a room name. What sizes a box in the Midlands is what the debris weighs, how it stacks, and whether the truck can reach the spot you have in mind.

Dale Carver has run roll-offs out of Broad River Road since 2014, and the pattern here is consistent. Columbia is not the north and it is not the coast. Our houses sit on crawlspaces or slabs, our old neighbourhoods are full of plaster and heart pine, our summers cook an attic until half of what is stored there comes out as trash, and our soil changes from one side of a street to the other.

The five sizes, with real numbers

Dimensions below are the working footprint, not marketing rounding. Weight allowances are typical ranges — confirm yours when you book, because material matters more than the box.

The 10 and the 40 are both specialists: the 10 exists because heavy material fills a weight allowance in a shallow box, the 40 because light material fills a volume. Most Columbia jobs land on a 20 yard roll-off or a 30 yard roll-off, and the full range sits on our dumpster sizes page.

Weight beats volume on dense material

This is the most common sizing mistake. Concrete, brick, block, tile and thinset run roughly 2,400 to 2,800 pounds per cubic yard. A driveway apron you could cross in eight steps, four inches thick, is well over a ton before you touch the sidewalk.

So a patio tear-out in Forest Acres, a brick walkway in Shandon, a tile floor with the mortar bed attached — those go in a 10 yard container, loaded flat, not heaped. The box will look a third full and already be at its limit. An overloaded roll-off is unsafe on the hoist and illegal on the road. We run these as a dedicated concrete and heavy debris load, kept clean so it reaches the right facility.

The rule worth memorising: if you can lift a piece with two hands and it surprises you, size on weight, not volume.

Plaster, lath and heart pine

Now apply that to the older neighbourhoods. Shandon, Elmwood Park, Cottontown, Waverly, Melrose Heights and Earlewood hold 1900s to 1940s bungalows, Craftsman and foursquares. Those walls are not drywall. Plaster over wood lath runs roughly two to three times the weight of drywall for the same wall area, so anyone who priced their demo off a modern renovation video will be badly out.

The framing behind it is heavier too. Old-growth heart pine studs, joists and flooring are denser than modern kiln-dried lumber. Gutting two rooms of plaster in a Shandon bungalow is a weight job, however small the square footage looks.

One caution on the old stock: pre-1980 houses routinely carry asbestos in floor tile and mastic, pipe wrap, plaster skim coats, siding and roofing felt, and pre-1978 houses carry lead paint under the EPA RRP rule. Demolition generally triggers an asbestos inspection and notification, now handled by the SC Department of Environmental Services after the 2024 DHEC split. We cannot take asbestos-containing material in any container. That change is recent, so confirm current requirements with SC DES.

Wet material is the other weight trap

Soaked carpet and pad, wet drywall, saturated batts and waterlogged subfloor all weigh far more than the dry version of themselves. After a flood, a burst supply line, or a crawlspace damp for a decade, a 30 can go overweight while it still looks half empty.

The October 2015 flood taught this town that lesson at scale. If your material is wet, size down and swap more often instead of forcing one big box — we run next-day swap-outs for this reason. More in our guide to flood and storm damage cleanup in Columbia.

Roofing is sized by squares and layers

Roofers speak this language; homeowners do not. A square is 100 square feet of roof. Architectural shingles run roughly 250 pounds per square, three-tab a little less, and the number that matters is squares multiplied by layers. Plenty of older Columbia stock has been shingled over more than once.

Practically: single-layer under about 20 squares fits a 15; 20 to 30 squares single-layer wants a 20; multi-layer tear-offs and anything above 30 squares move up. Add felt, nails and rotted decking. We spot roofing dumpster rentals close to the drip line, and the numbers are worked through in the roofing tear-off size guide.

The foundation fact that changes the arithmetic

Most national sizing guides are written for houses with a below-grade level. Columbia houses sit on crawlspaces or slabs, never basements. Older stock is on brick or block piers over a vented crawlspace; newer construction is slab-on-grade. That has two consequences.

First, a Columbia cleanout has no extra floor of accumulated contents to empty — no rec room, no workshop under the house, no thirty years of boxes on a lower level. Subtract that from any number you read online.

Second, we have an attic that a Columbia summer has already cooked. Tape, vinyl, photographs, adhesives, foam and stored furniture come down as trash rather than donations after fifteen summers at attic temperature. Work attics at dawn and plan for more volume than you expect. Then add the detached shed or carport, where the real accumulation lives on a Columbia lot.

Crawlspace debris is two different loads

Midlands humidity drives moisture into a vented crawl and the results are predictable: rotted band joists and floor joists, failed insulation hanging off the subfloor, ruined ductwork, mould, standing water, and whatever somebody shoved under the house twenty years ago. Termites are structural here, and a cosmetic remodel turns structural the moment that insulation comes off.

Sizing this means two streams. Wet fibreglass batts, collapsed poly vapour barrier and crushed flex duct are bulky, awkward and light — they eat volume and barely register on the scale. Rotted framing, old brick piers and any concrete or footing work is dense and does the opposite. Tell us the split; the detail is in our write-up on crawlspace moisture and termite damage debris.

The bulky-light jobs that want the big box

Real cases for a 40 yard roll-off look alike: high volume, low density, room on site. Deck framing and decking. Vinyl siding, nothing on the scale and endless in the box. Cabinetry from a kitchen or office tear-out. Fencing. Commercial fit-outs where ceiling grid, partitions and shelving come out at once. What does not belong in a 40 is anything dense — nobody has ever filled one with concrete.

Student rental turnover

USC drives two hard windows, May move-out and August move-in, across Five Points, Olympia, Rosewood, Shandon and the Vista. A standard make-ready is furniture, mattresses, carpet, a fridge nobody cleaned and four closets of leftovers: a 15 for a unit or small house, a 20 if you are doing several or pulling carpet throughout. Book early — containers, cleaners and painters all go solid in those fortnights. More in our guide to student rental turnover cleanouts.

Will it actually fit on your property?

Sizing is half the job; delivery is the other half. What the truck needs:

• Roughly 60 feet of straight approach to set a 20 or larger. The truck backs in and rolls the box off; it cannot pivot into place.
• About 10.5 feet of width the whole way — gate posts, mailbox brick, the camellia at the end of the drive.
• 20+ feet of overhead clearance for the hoist arm. This catches people — water oak and live oak limbs hang low over older streets, and a limb that clears a delivery van will not clear a raised hoist.
• Protection boards, standard on every drop, under the rails and wheels so the container never sits on bare driveway.

Then the ground. Columbia sits on the Fall Line where the Piedmont meets the Coastal Plain, and that split matters when a loaded truck is on your lot. Sandy sandhill soil gives way under a rear axle, especially on an unpaved side yard. Red clay ruts, holds water and stays soft for days after rain. If you know which you have, say so; if not, tell us what the yard does after a thunderstorm. Our notes on driveway protection during delivery cover the rest.

Street placement is its own problem in Five Points, Olympia and Shandon, where driveways are narrow, on-street parking is tight and a container in the right of way may need permission from the City of Columbia. Richland County, Lexington County, West Columbia, Cayce, Forest Acres, Irmo and Blythewood each run their own rules, and rules change — confirm with Richland County or the municipality you are actually in.

Timing the Midlands calendar

Spring severe weather — thunderstorms, hail, the occasional tornado — runs demand up across Richland and Lexington County, and an ice storm every few winters drops loblolly pine limbs across the Midlands; watch the National Weather Service before outdoor demo. The USC turnover fortnights are the tightest booking windows of the year, and from June through September heat sets the pace: a two-day job becomes three. Size for that, or plan a swap.

One scheduling note: yard trash cannot ride in a construction load. South Carolina keeps grass, leaves, brush and limbs out of landfills, so tree debris goes as a separate clean load to a composting or mulching facility. Whole tires, lead-acid batteries, used oil and white goods are also kept out of landfills, and leftover paint and chemicals belong at a county household hazardous waste drop-off.

How to describe your job on the phone

You do not need the answer. Give us five things:

1. What the material is. Not "remodel debris" — say plaster and lath, shingles, concrete, or carpet and furniture. Material is the whole ballgame.
2. Roughly how much. Rooms, squares of roof, feet of fence, square feet of patio. Any real number beats an adjective.
3. Whether it is wet. Flood, crawlspace, roof leak, standing damp. It changes the size.
4. Where it goes and what it passes. Driveway or street, gravel or concrete, low limbs, gate width.
5. When you need it and for how long. Same-day and next-day delivery are usually available, and with next-day swaps a smaller box run twice often beats one oversized one.

Between two sizes on a dense load, go smaller and swap. On a bulky, light load, go bigger the first time. That one rule fixes most of the mistakes we see.
