Sizing

What Size Dumpster Do I Need? An Honest Watertown 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 thirty 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, so it is never a surprise — but it is still money you did not need to spend.

There is a useful local benchmark for what weight actually costs. The Jefferson County transfer station charges $148 per ton for bulky items brought in by residents. That is the figure sitting behind every overage conversation in this county.

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 concrete, brick, 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. The most under-used size in the industry and frequently the right one here, because the older village lots in Carthage, Brownville and Sackets Harbor often will not take anything longer. It is also the standard PCS clear-out container.

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, and the right call for a barn teardown out in the county.

The weight traps around here

Concrete, block and stone

Roughly 4,000 pounds per cubic yard. A single cubic yard of broken slab weighs about as much as a small car. This is why we will not put concrete in anything larger than a 10 yard.

Old village building material

Jefferson County has a great deal of nineteenth-century stock — stone, plaster, lath and old-growth timber cut heavier than anything milled today. A 15 yard filled with that can hit its weight allowance at half volume. Tell us roughly when the house was built and we will size for weight rather than for rooms.

Anything that has been wet

Saturated drywall, insulation, carpet and subfloor weigh a multiple of their dry equivalent. That comes up constantly here — burst pipes in unheated camps, ice dam leaks, spring damp. Say so when you book.

Snow and ice in the container

Genuinely local, and people are surprised by it. An open container left through a lake-effect storm can take on a serious weight of snow, and once it compacts and refreezes you are paying to haul it. Keep the container covered in winter.

Winter changes the answer

Watertown sits in the lake-effect belt off Lake Ontario and takes some of the highest snow totals in the country. That affects sizing in two ways people rarely anticipate.

A frozen load will not tip. If wet material freezes into a solid block against the walls and floor of the container, the truck cannot empty it and has to come back. The fix is simple — keep it covered, and avoid layering wet debris on top of a hard freeze — but it is the single most common winter problem we deal with.

Placement caps the size. In deep winter the usable spot on a driveway is whatever is still clear after the plow and the shovel have been through. Sometimes that means a 15 yard where a 20 would have fitted in July. We would rather agree that in advance than send a truck that cannot place.

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 more per ton than clean concrete. Clean vegetation has its own route. Scrap metal is sometimes worth money rather than costing it. And in this county recycling is genuinely source-separated rather than single stream, so the habit of keeping materials apart is already the local norm.

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.
• Roughly when the house was built. Nineteenth-century material is much denser than post-war.
• Whether anything has been wet or frozen. It changes the weight answer completely.
• Where it is going, and in winter, where the snow gets pushed.

That is a ninety-second conversation and it is the difference between a flat rate that holds and an estimate that moves. Call and describe the job — we will size it honestly, including telling you when a smaller and cheaper container is the right answer, or when the city or county services would cover it for less.
