House Demolition
Expert Dumpster demolishing a home in Rochester, NY.Disposal of demolition debris is a major part of the cost of demolishing a home. Getting a rough estimate of how many roll off dumpsters you'll need for house demolition disposal makes it a lot easier to estimate the overall cost of demolition.  The number of dumpsters required to dispose of house demo debris will depend on the size of your home and the materials used to build it.  Here is a rough estimate of how many 40-yard dumpsters it will take to dispose of common-size houses that are stick-built.

How Many Dumpsters Does it Take to Demo a House?

How many dumpsters do I need to demolish a 2,000 sq. ft. house?

To simplify things, we’re going to take a more detailed look at how many dumpsters a typical stick-built 2,000 sq. ft. house will require. Because all houses are different, your exact results may vary considerably. Factors that can impact the required number of dumpsters include whether the home was built with a wood exterior or brick, on a concrete slab or with a basement, deconstructed for reusable materials prior to demo, and more.

First, let's calculate how many cubic yards of C&D (construction and demolition) debris the home will have from materials like wood, siding, roofing, lathe or drywall, and other miscellaneous components making up the home. Here, we are looking at only debris from the home. We're NOT including the concrete foundation and any tree canopy or green waste to remove. Those will be calculated separately.

Calculating the cubic yards of demolition debris is simple and involves converting the cubic footage of the structure to cubic yards while also accounting for the air space in the building (0.33). For our 2,000 sq. ft. house example, let's assume our home is 2 stories and the dimensions are 40 ft. x 25 ft.

The formula and calculation are:
C&D debris, including wood, siding, roofing, drywall, etc.
(Length (ft) x Width (ft) x Height (ft) x 0.33) ÷ 27 = cubic yards of demolition debris
(40 ft L x 25 ft W x 20 ft H x 0.33) ÷ 27 = 244.4 cubic yards of debris

To get the number of dumpsters needed for this portion of the debris, we divide our roughly 245 cubic yards of debris by the cubic yard capacity of the dumpster.
245 cubic yards of debris / 30 cubic yard dumpster = 8 dumpsters 
245 cubic yards of debris / 40 cubic yard dumpster = 6 dumpsters

For any significant demolition project, the hired dumpster service will need to be available for multiple trips back and forth to the landfill or recycling center. The dumpster company will deliver a container (or more in some cases) to the site of your intended demolition. You then fill up the dumpster, and the company loads it onto their truck, hauls it to the landfill/recycling facility, empties the container, and brings it back to the demo site, repeating this process until all the debris is gone.  Plan ahead so the dumpster company can dedicate a truck or two to your job for part or all of a day.
