How to Dispose of Lumber & Wood
Old studs, baseboards, fence boards, and cabinet scraps all count as lumber and wood waste — and not all of it needs to end up in a landfill. What you can do with it depends heavily on one thing: whether it's treated or untreated.
1. Sell It
Untreated lumber in decent condition — old barn boards, hardwood flooring, timber framing — can genuinely be worth something to reclaimed-wood buyers and local flea markets or Facebook Marketplace groups. Pressure-treated lumber is a much harder sell; most buyers won't touch it due to the chemical treatment.
2. Donate It
Habitat for Humanity ReStores accept unused or gently used lumber at many locations, along with cabinets, doors, and flooring. Not every ReStore takes every material, so a quick call before dropping off saves a wasted trip. Find your nearest ReStore →
3. Recycle It
Untreated wood can often be chipped or mulched at a local recycling facility. Pressure-treated lumber cannot — it should never be burned or mulched, since the preservative chemicals (including arsenic compounds in lumber treated before 2004) release into ash or wood chips.

4. Dispose of It
For a full renovation, deck teardown, or shed demolition generating more lumber than you can sell, donate, or recycle piece by piece, a dumpster is the practical answer — especially once nails, hardware, and mixed treated/untreated wood make sorting impractical.
NorthPoint's Construction Debris page covers sizing and pricing specifics for this exact material.
5. What This Actually Costs
A typical single-room renovation or deck teardown generates well under a ton of lumber debris — light enough that weight rarely drives the cost here, unlike concrete or shingles. The bigger cost factor is simply container size: a full deck or shed demolition usually needs a 15 or 20-yard container just for the volume, even though the material itself is light.
Common Questions
Can treated and untreated lumber go in the same dumpster?
Yes — for disposal purposes, they can be combined in a standard container. The sell/donate/recycle distinction above only matters if you're trying to divert wood from disposal; once it's headed to a dumpster, mixed lumber is fine.
Does painted or stained wood count as treated lumber?
Not in the pressure-treatment sense — paint and stain don't change how the wood is processed at disposal. Pressure-treated specifically refers to chemical preservative treatment (often visible as a greenish tint), which is the distinction that matters for recycling.
Can plywood, particleboard, and OSB go in with regular lumber?
Yes, these are accepted along with solid lumber as standard construction debris.
Is lumber and wood debris likely to hit a weight limit?
Less likely than concrete or shingles — wood is comparatively light for its volume, so a standard container's weight allowance rarely gets challenged by lumber alone unless it's a very large teardown.
Can I burn scrap lumber instead of disposing of it?
Untreated wood can typically be burned where local ordinances allow open burning, though most municipalities require a permit for anything beyond a small brush pile. Pressure-treated lumber should never be burned — the preservative chemicals release into the smoke and ash.
What's the difference between reclaimed and just old lumber?
Reclaimed generally implies the wood has been cleaned up and is being marketed for reuse — old barn boards, timber beams. Just because lumber is old doesn't mean it has resale value; condition and species matter more than age alone.
Does insulation attached to lumber, like in old framing, need to be removed first?
For disposal, no — insulation attached to framing lumber can go in the same container. If you're trying to sell or donate the lumber specifically, most buyers will expect it stripped of insulation and drywall first.
Is there a cost difference between disposing of treated versus untreated lumber?
Not typically for standard dumpster disposal — both are billed the same way, by container size and weight. The cost difference shows up only if you're trying to recycle wood, since treated lumber has far fewer recycling options.
