Match the container to the debris rather than to the room count. Five sizes cover everything from one bathroom to a commercial tear-down.
The 10-Yard Dumpster is the dense-material size. A clean load of concrete, brick, block or asphalt hits its weight limit long before it fills, so this is the container for a patio removal or a foundation repair. It also fits in a single driveway bay, which matters on the tighter lots near the river.
The 15-Yard Dumpster covers a garage cleanout, a kitchen or bathroom remodel, or a small roof job. It is the useful middle step when a 10-yard would be tight and a 20-yard is more than the job needs.
The 20-Yard Dumpster is the size most often booked for residential work in San Marcos. Whole-house cleanouts, flooring tear-outs and multi-room renovations all fit, and it is low enough to load by hand over the side.
The 30-Yard Dumpster suits new residential construction, large additions and serious demolition. Once framing lumber, drywall and roof decking are involved, volume rises faster than weight and the extra capacity saves a second haul.
The 40-Yard Dumpster is for commercial demolition, industrial cleanouts and large-scale construction. It is the largest container offered. It needs a straight approach, a level drop point and real clearance overhead, so talk through access before you book one.
