Sizing

What Size Dumpster Do I Need? An Honest Port Charlotte Guide

Most sizing guides lead with cubic yards. That is the least useful number, because almost nobody can estimate their own debris in cubic yards. Here is how we actually do it on the phone.

Why cubic yards is the wrong question

Every dumpster sizing guide opens the same way: a 10 yard holds ten cubic yards, a 20 yard holds twenty. True, and almost completely useless, because nobody standing in their garage looking at twenty years of accumulated stuff can convert that into cubic yards.

What we actually ask on the phone is three questions. What are you throwing away? How much of it, in terms you can picture — pickup loads, rooms, squares of roof? And where is it going to sit? Those three answers get us to the right container about ninety-five percent of the time, and everything after that is about weight.

The two constraints: volume and weight

Every container has two limits and you will hit one of them first. Volume is the obvious one: the box is only so big and you cannot legally load above the top rail. Weight is the one people forget, and it is the one that costs money.

Each size comes with an included tonnage. A 10 yard typically includes one to two tons, a 30 yard four to five. Go over and you pay a per-ton overage rate, which we quote before you book.

What each size really holds

10 yard — 12 ft × 8 ft × 3.5 ft

Three to four pickup loads. One to two tons included. The small-job container and, more importantly, the heavy material container. A bathroom gut. A patio slab. Broken block, stucco and tile. Low three-and-a-half-foot sides mean you can throw material over the wall without a ramp.

15 yard — 16 ft × 8 ft × 4 ft

Five to six pickup loads. Two to three tons. Under-used and frequently right here — it suits a lanai or screen cage replacement, a single-room renovation, or a driveway that is wide but shallow, which describes a great many Port Charlotte lots.

20 yard — 22 ft × 8 ft × 4.5 ft

Seven to eight pickup loads. Three to four tons. Our most popular container by a wide margin, because it covers the three most common real-world projects: a shingle re-roof, a full kitchen renovation, and a three-bedroom whole-house clear-out.

30 yard — 22 ft × 8 ft × 6 ft

Ten to twelve pickup loads. Four to five tons. Same footprint as the 20 with eighteen more inches of height, so it holds half again as much without needing any more driveway. The builder's container.

Worked examples from real Charlotte County jobs

The weight traps around here

Block, stucco and tile

Florida houses are concrete block, not stick frame, and that changes interior demolition completely. Block, stucco, tile and the mortar between them are all dense. A container that would be half full of framing timber is at its weight allowance with block.

Concrete and pavers

Roughly 4,000 pounds per cubic yard. A single cubic yard of broken slab weighs about as much as a small car. Worth knowing: the county landfill takes clean tile, dirt, gravel and small pieces of concrete and pavers at no charge — so if you have a genuinely clean load of that material, separating it is worth real money.

Anything that has been wet

Saturated drywall, insulation, flooring and cabinetry weigh a multiple of their dry equivalent. After 2022 this became the most common sizing conversation we have. If your job is storm or flood related, say so and we will size for weight rather than for how the pile looks.

Rain in an open container

This is Florida in the wet season. An afternoon storm puts real water into an open container, and you pay for it by the ton. Keep dense loads covered.

Lanais, screen cages and why they fool people

Worth its own section because it is the single most mis-sized job in this county.

A screen enclosure looks enormous coming down — a pile of aluminium framing and screen that seems to fill the whole back yard. And it does fill a container, fast. But it weighs almost nothing.

So size it by volume. A typical pool cage wants a 15 or even a 20 yard on volume alone, while barely troubling the weight allowance. And if there is a real quantity of aluminium, pull it out as a separate stream — it is scrap with genuine value, and separating it both shrinks the container you need and can put money back.

The trap is mixing it with the concrete from the deck. That combination gets you the worst of both: a container filled by the aluminium and weighed down by the slab.

Two smaller containers vs one big one

On larger jobs this is frequently the cheaper route, and almost nobody asks about it.

Disposal is priced by stream. Mixed construction and demolition debris costs the most per ton. Clean tile, dirt, gravel and small concrete and paver pieces go in as clean debris at no charge at the county landfill. Aluminium and scrap metal have positive value.

So on a pool deck and cage removal producing concrete, aluminium and general debris, two or three containers will very often cost less in total than one mixed 30 yard, even after paying for the extra movements.

The test is whether you have enough of a clean stream to justify a dedicated container. Half a container of clean concrete, yes. A wheelbarrow full, no.

How to describe your job on the phone

• What the material is. "Kitchen cabinets, countertop, appliances and about 200 square feet of tile floor" tells us everything.
• Roughly how much. Rooms, squares of roof, or pickup loads.
• Whether it is block or frame, and whether tile is coming up.
• Whether anything has been wet. It changes the weight answer completely.
• Whether the job is permitted, and the permit number if you have it. The county landfill asks for it on construction debris — more on that here.
• Where it is going, and whether the driveway is pavers.

That is a ninety-second conversation and it is the difference between a flat rate that holds and an estimate that moves.
