Deck & Fence Demolition: Dumpster Sizing in Chattanooga

Early fall is prime deck-and-fence season in Chattanooga — the humidity breaks, and homeowners in Hixson, East Brainerd, and Ooltewah start tearing out the deck that's been sagging since the last freeze-thaw cycle before winter makes the job miserable. Demo is the easy part. Getting the debris off your property without a surprise overage fee is where most people trip up.

Why deck debris is heavier than it looks

Pressure-treated lumber is denser and wetter than the framing lumber in a typical remodel — it's been sitting outside absorbing moisture for years, and treated pine runs noticeably heavier per board foot than kiln-dried interior framing. A deck that looks like "just some 2x6 boards" can weigh in well past what the same square footage of drywall or cabinetry would. Add in the joists, ledger board, and any composite decking (which is denser still — composite boards are essentially wood fiber bonded with plastic), and a mid-size deck teardown adds up fast.

Chattanooga haulers bill against a tonnage allowance, not just how full the box looks (see our pricing breakdown for how that works across sizes). Overages run roughly $0.04–$0.05 per pound, or about $75 per ton — the same rate applied when a load crosses the scale at a facility like Birchwood Landfill. Treated lumber is exactly the kind of debris that sneaks past a weight limit while the container still looks half-empty.

Sizing by project

• A single fence line (100–150 linear feet of wood privacy fence) — a 10-yard dumpster usually handles posts, pickets, and rails with room to spare. Concrete footings are the wildcard; see below.
• A mid-size deck (200–350 square feet, standard framing) — plan on a 15-yard. That's enough volume for decking boards, joists, and railing without immediately bumping into the 2-ton weight allowance.
• A large or multi-level deck, or a deck-plus-fence combo job — go with a 20-yard. Contractors doing a full deck rebuild alongside a kitchen or addition often default to 20-yard anyway; check our kitchen remodel guide if that's part of a bigger project.

When the square footage is borderline between two sizes, size up. A second haul costs far more than the price difference between a 10 and a 15-yard box, and that math only gets worse once a hauler is already loaded and driving back across town.

Footings change the math

Wood is bulky but light-ish per cubic foot; concrete is the opposite. If your deck posts or fence corners sit on poured concrete footings, breaking those out adds real tonnage fast — the same density problem covered in our concrete disposal guide. A few footings mixed into a wood-debris load are usually fine, but if you're pulling more than a handful, or breaking out an old patio slab along with the deck, ask about a dedicated heavy-debris container instead of stacking it all into one box. Mixing a large concrete volume with lumber in a standard roll-off is the fastest way to hit an overage on what looked like a straightforward wood-demo job.

What else typically comes out with a deck or fence

• Screws, nails, and metal brackets are fine mixed in with the wood — haulers don't require you to de-nail lumber before it goes in.
• Composite decking (Trex-style boards) goes in the dumpster like wood; it just weighs more, so factor that into sizing if your deck is composite rather than pine.
• Old paint or stain cans left over from deck maintenance need to be handled separately — leftover liquid paint and solvents aren't dumpster-legal anywhere in Hamilton County. Our what can and can't go in a dumpster guide covers the full prohibited list.
• Chain-link fencing with metal posts can often be scrapped separately for value rather than landfilled — worth a quick call to a local scrap yard before you toss it in with wood debris.

Placement and driveway access

Deck and fence teardown debris usually needs to get from the backyard to the dumpster, which means placement matters more here than on an indoor remodel. If the container has to sit in the driveway rather than the backyard, ask your hauler about driveway protection boards, and confirm the truck has a clear path — a fence you're about to demolish is, conveniently, no longer an obstacle to work around. If the box has to sit on the street instead of your property, that triggers the City of Chattanooga's CDOT Work Zone Permit; our permit guide breaks down costs and how neighboring towns like Signal Mountain and East Ridge handle it differently.

A quick sizing checklist

1. Measure linear footage (fence) or square footage (deck) before you call — haulers size faster with real numbers.
2. Note whether concrete footings or a patio slab are coming out too; that changes the debris density, not just the volume.
3. Check whether decking is composite or wood — composite adds weight per square foot.
4. When in doubt between two sizes, size up. It's cheaper than a second trip.
