Garage Cleanout Dumpster Guide: What Size You Need and What It Costs in Bucks & Montgomery County

A garage cleanout is one of those projects that feels endless until you have a dumpster sitting in the driveway — then it goes fast. The hardest part is usually just deciding what size to rent and knowing what you're allowed to throw away. Here's a straightforward guide for homeowners across Bucks and Montgomery County.

What size dumpster do you need for a garage?

Garage junk is deceptive. Old shelving, broken furniture, boxes of who-knows-what, kids' outgrown gear — bulky items eat up space far faster than their weight suggests. A good rule of thumb:

  • 10-yard: A single-car garage with light-to-moderate clutter — boxes, bags, small furniture.

  • 15-yard: A two-car garage, or a single garage packed to the rafters. The most popular size for a full residential cleanout.

  • 20-yard: A truly packed garage with large furniture, appliances, workbenches, and years of accumulation.

If you're on the fence between two sizes, go one size up. Paying a little more for room you don't quite fill beats filling a smaller dumpster and staring at a leftover pile with nowhere to put it.

What does a garage cleanout dumpster cost?

Our roll-off rentals start at $365 for a 10-yard, $400 for a 15-yard, and $475 for a 20-yard, and every rental includes a generous weight allowance — for ordinary garage junk you'll almost always run out of space before you run out of weight. Pricing is flat and up front, with no surprise fees.

What can (and can't) go in the dumpster?

Most of what's in a garage is fair game: furniture, shelving, cardboard, tools, bikes, toys, general household junk, and construction debris from a project. A few things are not allowed and need separate disposal:

  • Paint, stains, solvents, and other liquid chemicals

  • Tires, car batteries, and motor oil

  • Propane tanks and other pressurized cylinders

  • Refrigerators, freezers, and AC units containing Freon

How to knock it out in a weekend

With the dumpster in your driveway, a garage cleanout is very doable in a single weekend:

  • Sort as you go. Three zones — keep, donate, toss — so you're not re-handling the same box twice.

  • Work one wall at a time. Clearing a full section gives you space to stage the rest.

  • Toss the big stuff first. Getting bulky furniture and shelving into the dumpster early tells you how much room you really have.
