Padding and Carpet Are Two Different Problems
Most people rip up carpet and padding together and assume they go to the same place. They don't. Carpet and carpet padding are made from completely different materials, recycle differently, and — here's the fun part — the padding is almost always the grosser of the two.
Carpet is typically nylon, polyester, or polypropylene fiber on a woven or glued backing. Padding is a dense foam, rubber, or fiber pad that sits between the carpet and the subfloor. It absorbs everything that ever spilled, leaked, or seeped through the carpet above it — pet urine, water damage, mold, decades of dust compressed into a quarter-inch sheet of regret.
When you pull up carpet that's been down for 10+ years, the padding often disintegrates on contact. It crumbles, sticks to the subfloor, and releases a smell that hits you like a wall. Wear gloves. Wear a mask. And don't do this in a closed room.
Types of Carpet Padding and Why It Matters
- Rebond (bonded urethane) — The most common type. That multicolored speckled foam you see in most homes. Made from recycled foam scraps bonded together. Recyclable in theory, but few Oregon facilities accept it once it's been used and contaminated.
- Foam rubber — Denser and heavier than rebond. Common in older homes. Less recyclable because of the rubber content.
- Fiber padding — Made from recycled textile fibers or synthetic felt. Often found in commercial settings. The lightest type, but also the most prone to absorbing moisture and developing mold.
- Waffle rubber — That bumpy rubber padding from the 1960s and 70s. Heavy, deteriorated, and sometimes fused to the subfloor with age. This stuff is a nightmare to remove and is not recyclable.
The type determines weight, difficulty of removal, and disposal options. A 12x12 room of rebond padding weighs about 30 to 50 pounds. Waffle rubber from the same room? Easily 60 to 80 pounds, and it comes up in pieces.
Why Padding Removal Is the Worst Part of the Job
The carpet comes up in strips — satisfying, even. You score it with a utility knife, grab the edge, and pull. It rolls up relatively clean.
Padding does not cooperate. Here's what actually happens:
- It's glued or stapled to the subfloor. Or both.
- Old padding crumbles when you pull it, leaving chunks stuck to the adhesive.
- Staples — hundreds of them — remain in the subfloor and need pulling with pliers.
- If there's been any moisture, the padding has bonded to the subfloor adhesive to create a single fused layer that requires a floor scraper to remove.
- Pet urine soaks through carpet into padding and then into the subfloor. The padding holds the smell. Pulling it releases years of concentrated odor.
Professionals use floor scrapers, pry bars, and sometimes oscillating multi-tools to get padding up cleanly. It's a hands-and-knees job that takes longer than the carpet removal itself.
Disposal Options in Oregon
Used carpet padding is classified as construction and demolition (C&D) waste in Oregon. Your options:
- Transfer stations — Metro transfer stations in the Portland area accept carpet padding as C&D debris. Fees are based on weight — typically $80 to $120 per ton (minimum charge of $25 to $35 per load). Lane County and other regional facilities have similar programs.
- Junk removal service — A construction debris removal service handles padding as part of a flooring removal job. They'll take the carpet, padding, tack strips, and staples in one haul.
- Dumpster rental — If you're doing a large area, a 10 or 20-yard roll-off dumpster is cost-effective. Carpet and padding can go in together. Expect $300 to $500 for a 10-yard container in Portland.
- Regular trash — Small amounts (one room or less) might fit in your regular trash service if cut into small pieces and bagged. Check with your hauler first — some won't accept it.
Carpet recycling programs like CARE (Carpet America Recovery Effort) focus on the carpet itself, not the padding. Don't expect recycling for used residential padding — it's almost always landfill-bound once it's been in service.
What Padding Removal and Disposal Costs
| Scenario | Typical Cost |
|---|---|
| 1-2 rooms of carpet + padding (DIY removal, hauled) | $75 – $150 |
| Full house carpet + padding (professional removal + haul) | $400 – $800 |
| Commercial space (1,000+ sq ft) | $500 – $1,500 |
If you're doing the removal yourself, the disposal cost is just the transfer station fee or dumpster rental. If you're hiring a crew to rip it up and haul it, the labor is the bigger expense. Most junk removal companies quote flooring jobs by volume rather than square footage.
Time to Rip It Out
Old carpet padding isn't getting better with time. It's getting moldier, smellier, and more fused to your subfloor. If you're replacing flooring or renovating, deal with the padding now. Bag it, haul it, or call someone to do it for you. Your subfloor (and your nose) will thank you. Get a removal estimate and get it done.
