The cost of a reliable Mill Valley dumpster rental mainly depends on the size of the dumpster to be rented. Dumpster sizes usually come in 10-yard, 20-yard and 30-yard measurements. Although these are typically the three most popular types required for residential jobs, there are actually additional sizes. There are also 12-yard, 15-yard, 25-yard, and 40-yard dumpsters offered. Several projects even require a 50-yard dumpster. However, only a few of these sizes are available depending on the area.
