Done the Right Way
Heavy debris is the dumpster rental category where the most money gets wasted, the most overage fees get charged, and the most projects end up in disputes with their rental company. Almost all of it is preventable with a properly scoped rental upfront.
We provide heavy debris roll off service across San Marino, CA for contractors, demolition crews, and homeowners who'd rather not learn the weight pricing rules by getting surprised on the invoice.
Standard dumpster rentals price on volume — fill the bin to the rim, pay one flat rate. Heavy debris doesn't work that way, for reasons that are physics, not policy.
A 20-yard dumpster full of household junk weighs around 2 tons. The same dumpster full of concrete weighs roughly 20 tons. ... You can't legally drive an over-weight dumpster down a highway in San Marino.
