How do I dispose of old PT deck boards in Vancouver?

Pressure-treated lumber cannot go in regular household garbage or yard waste in Metro Vancouver and requires special disposal due to the chemical preservatives used in the treatment process. Most PT lumber contains copper-based preservatives (ACQ) that are considered hazardous waste and must be handled through designated facilities.

Metro Vancouver Disposal Options

City of Vancouver Transfer Stations accept pressure-treated lumber for a fee. The Vancouver South Transfer Station (8400 Manitoba Street) and North Shore Transfer Station (335 Brooksbank Avenue, North Vancouver) both handle treated wood disposal. Expect to pay approximately $140-160 per tonne, with a minimum charge around $15-20 for small loads. You'll need to separate PT lumber from regular untreated wood — they have different disposal streams and pricing.

Private waste management companies like GFL Environmental, Waste Management, and smaller local haulers offer PT lumber disposal services. Many will provide bins or pickup services for larger deck demolition projects. This is often the most convenient option if you're having an old deck professionally demolished, as the contractor typically arranges disposal as part of their service.

Some municipal transfer stations in other Metro Vancouver communities also accept treated lumber — check with Burnaby (Burnaby Heights Works Yard), Surrey (multiple locations), Richmond, and your local municipality's waste management department for specific policies and fees. Each municipality has slightly different rules and pricing.

What You Cannot Do

Never burn pressure-treated lumber — the chemical preservatives release toxic fumes when burned, creating serious health hazards. This includes backyard fire pits, wood stoves, and any other combustion. Even small amounts mixed with regular firewood create dangerous emissions.

PT lumber cannot go in regular construction waste bins unless specifically designated for treated wood. Most construction waste is processed for recycling or biomass fuel, and treated lumber contaminates these streams. Always confirm with your waste hauler that they accept treated lumber before loading it in a bin.

Landfilling is restricted — while some PT lumber may end up in landfills, it requires special handling and cannot be mixed with organic waste or materials destined for composting.

Preparation for Disposal

Remove all metal fasteners — screws, nails, bolts, and joist hangers should be removed and recycled separately through scrap metal dealers. This makes the wood processing easier and recovers valuable metal. A cordless drill with a magnetic bit holder makes screw removal much faster than trying to pry boards apart.

Separate treated from untreated wood — regular cedar decking, untreated framing lumber, and other non-PT materials can often be disposed of more cheaply or even recycled into mulch or biomass fuel. PT lumber is typically stamped with treatment information, but if you're unsure, the greenish tint and heavier weight are telltale signs.

Cut to manageable lengths if transporting yourself — most transfer stations prefer lumber cut to 4-8 foot lengths for easier handling. This also helps you fit more in a pickup truck or trailer.

Cost Considerations

Budget $100-300 for disposal of a typical 300 square foot deck's worth of PT lumber, depending on the disposal method and total weight. Professional demolition companies often include disposal in their quoted price, which can be more cost-effective than DIY disposal when you factor in your time, vehicle wear, and transfer station fees.

Consider timing with a larger renovation project — if you're planning other construction work, coordinating PT lumber disposal with a larger waste bin rental can be more economical than multiple small trips to transfer stations.

The key is planning ahead and budgeting for proper disposal as part of your deck replacement project. Improper disposal isn't just environmentally irresponsible — it can result in fines and creates health hazards for waste workers and the community.
