TL;DR
A subfloor tear-out usually produces 3 to 8 pounds of debris per square foot, which puts a 200 square foot room somewhere between 600 and 1,600 pounds before you count the finish flooring on top of it. Hauling a single room of subfloor debris is priced mostly by that weight. Multiple layers, adhesive, and old fasteners push it higher.
The reason subfloor jobs blow past their estimate is almost never the plywood. It is the layers underneath the plywood that nobody knew were there.
What Are You Actually Tearing Out?
A content capsule for this one: subfloor removal means taking up the structural sheathing that spans the floor joists, plus every underlayment and adhesive layer bonded to it. In an older house that can be four or five distinct layers, and each layer disposes differently.
Here is the stack you commonly find, top to bottom.
Finish flooring. Carpet and pad, vinyl, laminate, tile, or hardwood. This comes off first and is its own disposal category.
Underlayment. Quarter-inch luan plywood, particleboard, cement backer board, or a poured self-leveling compound. Backer board and leveling compound are heavy and dusty.
Original subfloor. Either 3/4 inch plywood or OSB in newer construction, or diagonal 1 by 6 planking in houses built before roughly 1950. Previous remodels often added a second layer rather than removing the first.
Every added layer is more weight, more fasteners, and more time. That is where budgets go.
Weight Per Square Foot, Honestly
Rough working figures for planning a haul:
| Layer | Weight per square foot |
|---|---|
| 3/4 inch plywood or OSB subfloor | 2.3 to 2.7 pounds |
| 1 by 6 plank subfloor | 2.0 to 2.5 pounds |
| 1/4 inch luan underlayment | 0.7 to 0.9 pounds |
| Particleboard underlayment | 1.5 to 2.0 pounds |
| 1/4 inch cement backer board | 2.8 to 3.2 pounds |
| Self-leveling compound residue | 1.0 to 4.0 pounds |
Add the finish flooring separately. Carpet and pad run about 0.5 to 1 pound per square foot. Ceramic tile with thinset runs 4 to 6.
A 300 square foot kitchen with tile over backer board over plywood is comfortably over 3,000 pounds all in. That is a weight-limited load, not a volume-limited one, and it prices accordingly.
Fasteners Are the Real Hazard
Subfloor is attached with a brutal amount of hardware: ring-shank nails every 6 inches on the edges, screws in the field, staples by the hundred from the underlayment, and construction adhesive under all of it in newer work.
Cut-up sections are dangerous to carry, because every piece has nails pointing both directions. Carry these on edge, not flat against a body, and gloves are the minimum. Fasteners left behind cause injuries after the debris is gone, so sweep the joists with a magnet before anyone walks the open floor.
The nails do not disqualify the load. Construction debris haulers expect nails in wood. What they do disqualify is the clean wood recycling route, which was already closed to glued sheet goods.
Sequence: Finish Flooring First, Always
Pull the finish layer off before the subfloor, even though it is tempting to cut through everything at once.
First, the finish material may have its own disposal path. Carpet has recycling options in some regions, covered in our guide to how to dispose of carpet. Old vinyl and tile need their own handling and sometimes testing, as described in removing old vinyl flooring and tile. Solid hardwood may have salvage value, covered in hardwood floor tear-out.
Second, cutting a full stack with a circular saw means setting the blade deep enough to reach the joists, which is how people cut through joists, plumbing, and wiring. Take the layers one at a time and reset the depth for each.
The Pre-1980 Pause
Two flooring materials in older houses require you to stop and test rather than cut.
Nine by nine inch vinyl floor tile, and the black cutback adhesive under vinyl of any age, may contain asbestos. So may some sheet vinyl backings. Sanding, grinding, or sawing through these releases fibers.
If the house predates 1980 and there is old vinyl or unidentified adhesive in the stack, hire an accredited inspector to sample and test before demolition. If it comes back positive, a licensed asbestos abatement contractor does the removal. Do not attempt a workaround, and do not expect any junk removal company to accept suspected asbestos material. They cannot legally take it.

Current Market Reality
Real quotes climb when the debris has to come down stairs, when the material is wet from a leak that caused the tear-out in the first place, and when cement backer board or leveling compound is in the mix. Water-damaged subfloor can weigh half again what the same material weighs dry. Tipping fees for mixed construction debris are charged per ton and are the largest single line on most invoices. The broader picture is in our construction debris removal cost guide.
How subfloor debris jobs compare with one another:
| Scope | Relative cost (lower to higher) |
|---|---|
| Single small room, one layer | Lower |
| Single room, multiple layers | Lower to middle |
| Kitchen or bath with backer board and tile | Middle |
| Whole floor of a house, 800 to 1,200 square feet | Higher |
| Overweight surcharge per extra ton | An add-on, per ton |

Staging So the Haul Goes Fast
Cut the subfloor into pieces one person can carry, roughly 2 by 4 feet. Bigger sections seem more efficient and are not, because they need two people and they do not stack.
Stack the pieces flat outside near the truck path rather than piling them loose. A flat stack of the same material takes a fraction of the space and loads in a fraction of the time, and crew time is billable.
FAQ
How much does subfloor removal debris weigh?
Plan on 3 to 8 pounds per square foot depending on how many layers are present. A 200 square foot room with a single plywood layer is around 600 pounds. The same room with tile, backer board, and two plywood layers can exceed 2,000 pounds.
Can subfloor plywood be recycled?
Generally no. Plywood and OSB are bonded with adhesive, which excludes them from clean wood recycling at most facilities. Add construction adhesive residue and hundreds of fasteners and the material goes out as mixed construction debris to landfill.
Do I have to remove the old subfloor or can I go over it?
If the existing subfloor is flat, dry, structurally sound, and firmly fastened, adding a new layer over it is common practice. Removal is required when the material is water damaged, rotted, badly out of plane, or when the added height would break door and appliance clearances.
What if there is old vinyl tile under the flooring?
Stop. Nine by nine inch vinyl tile and black cutback adhesive in pre-1980 buildings may contain asbestos. Have an accredited inspector test before any cutting or scraping. A positive result means a licensed abatement contractor handles the removal, not a demolition crew or a hauler.
How do I get subfloor debris out of an upper floor?
Cut it into carryable pieces and take it down by hand, or use a properly rated debris chute out a window if the volume justifies setup. Do not drop material down a stairwell. Bagged and stacked debris staged at ground level lowers the labor portion of a haul quote.
Getting It Hauled Away
Subfloor jobs price on weight, layers, and stairs, in that order. Test anything questionable before you cut it, take the layers down one at a time, and stack the pieces flat where a truck can reach them. Otesse can clear staged subfloor and flooring debris through our junk removal service. Reach out to get a quote with your square footage and the layers you expect to find.
