A dump trailer rental is quoted as one flat number before it's dropped. The number covers the drop, the pickup and the dump run. You don't get a separate landfill bill later.
Two sizes, two prices, both published on Rob's booking page: the 14-yard is $350 and the 16-yard is $400. Each rental is 3 days with 2 tons of weight included. Need it longer? It's $40 per additional day. Rob tells you which trailer fits your job over the phone, based on what you're throwing out and how long you need it.
Two tons covers most household and remodel loads. Past that it's $70 per ton, and Rob keeps a card on file so the overage is settled without a second trip. Concrete and dirt don't go in the trailers at all; Rob partners with dump trucks and recyclers for those and quotes them per job. Tile rides, but carries an extra dump-fee charge. Shingles ride and are the load most likely to pass 2 tons.
