Why Rent a Dumpster for Deck Removal?
Deck removal generates a surprising amount of debris. Even a modest 12×16 foot deck produces 2-3 tons of material including deck boards, joists, beams, posts, railings, and fasteners. A dumpster on-site eliminates dozens of trips to the dump and keeps your project moving efficiently.
💡 Did You Know?
A typical deck removal creates 15-25 cubic yards of debris. Without a dumpster, you'd need 8-12 pickup truck loads to haul it away—each trip taking 1-2 hours including loading, driving, and unloading fees.
Dumpster vs. Other Disposal Methods
| Method | Cost | Time | Best For |

| Dumpster Rental | $350-$650 | Work at your pace | DIY deck removal |
| Pickup Truck Loads | $40-60/trip + time | 8-12+ trips | Very small decks only |
| Junk Removal Service | $500-$1,500+ | 1 day (labor included) | Don't want to do the work |
| Contractor Haul-Away | Included in bid | N/A | Hiring deck demolition |
Dumpster Sizes for Deck Removal
Choosing the right dumpster size depends on your deck's square footage and construction. Wood is bulky but not extremely heavy, so volume is typically the limiting factor rather than weight.
15-Yard Dumpster
- Small decks under 200 sq ft
- ~15 pickup truck loads
- Holds 2-3 tons
- Dimensions: 16'L × 7.5'W × 4.5'H
20-Yard Dumpster
- Medium decks 200-400 sq ft
- ~20 pickup truck loads
- Most popular for deck removal
- Dimensions: 22'L × 7.5'W × 4.5'H
30-Yard Dumpster
- Large decks 400+ sq ft
- Multi-level or wraparound decks
- ~30 pickup truck loads
- Dimensions: 22'L × 7.5'W × 6'H
📏 Quick Sizing Formula
Deck sq ft ÷ 15 = estimated cubic yards of debris
Example: 300 sq ft deck ÷ 15 = 20 cubic yards → 20-yard dumpster
When in doubt, size up. Overage fees are more expensive than the larger dumpster.
Treated Wood Disposal: What You Need to Know
Most decks built since the 1970s use pressure-treated lumber to resist rot and insects. While you should never burn treated wood (it releases toxic chemicals), landfill disposal via dumpster is the accepted method.
Types of Treated Wood
ACQ (Alkaline Copper Quaternary)
Current standard. Accepted by all dumpster companies.
CA (Copper Azole)
Similar to ACQ. No special disposal needed.
CCA (Chromated Copper Arsenate)
Contains arsenic. Some areas require special handling—ask when booking.
⚠️ CCA Treated Wood (Pre-2004)
If your deck was built before 2004, it may contain CCA-treated lumber with arsenic compounds. While most dumpster companies still accept it for landfill disposal, some counties have restrictions. Mention the age of your deck when booking to confirm acceptance and any additional requirements.
How to Demolish a Deck for Dumpster Disposal
Working systematically makes deck removal safer and more efficient. Follow this sequence to minimize effort and maximize safety.
-
Remove Railings and Accessories
Start with railings, balusters, post caps, and any attached features. Use a drill for screwed connections or a pry bar for nailed ones. This opens up workspace and removes trip hazards.
-
Pull Up Deck Boards
Work from the outer edge toward the house. For screwed boards, reverse the screws with a drill. For nailed boards, use a pry bar and hammer. Cut long boards into 4-6 foot sections as you go—they'll pack more efficiently in the dumpster.
-
Cut and Remove Joists
With the deck boards gone, joists are exposed. Use a reciprocating saw to cut them into manageable sections. Remove joist hangers from the ledger board.
-
Remove the Ledger Board
The ledger attaches the deck to your house. Remove bolts or lag screws carefully to avoid damaging siding. Inspect the house sheathing for rot—this is a common problem area.
-
Demolish Beams and Posts
Cut beams into sections that fit in the dumpster. Posts can be cut at ground level or dug out depending on your plans. If building a new deck, you may be able to reuse existing concrete footings.
-
Handle Concrete Footings
Concrete footings can stay buried if you're not building again. For removal, dig around the footing and lever it out. Note: heavy concrete may have weight restrictions in your dumpster—dispose separately if needed.
-
Load the Dumpster
Stack flat boards horizontally. Place heavy items (posts, beams) on the bottom. Break down large pieces to maximize space. Keep debris below the fill line.
-
Final Cleanup
Sweep or rake the area for nails, screws, and splinters. A magnet sweep catches loose fasteners. Check the lawn and adjacent areas where debris may have scattered.
🦺 Safety Requirements
- Safety glasses — essential for prying and cutting
- Heavy work gloves — protect against splinters and nails
- Steel-toe boots — heavy boards and posts are dropping
- Dust mask — sawdust from treated wood is irritating
- Hard hat — for elevated deck demolition
Deck Debris Weight Guide
Understanding typical weights helps you avoid dumpster overweight fees. Most deck materials are bulky but not extremely heavy, so you'll usually hit volume limits before weight limits.
| Material | Weight per Sq Ft | Notes |
|---|---|---|
| Pressure-treated lumber deck | 3-4 lbs/sq ft | Most common deck type |
| Cedar/redwood deck | 2-3 lbs/sq ft | Lighter than treated lumber |
| Composite decking | 4-5 lbs/sq ft | Heavier than wood |
| Deck framing (joists/beams) | 2-3 lbs/sq ft | Add to decking weight |
| Railings & posts | 150-300 lbs total | Varies by length/style |
| Concrete footings | 75-150 lbs each | May have weight restrictions |
⚖️ Typical Deck Weight Example
A 300 sq ft pressure-treated deck with framing weighs approximately:
Decking: 300 × 3.5 lbs = 1,050 lbs
Framing: 300 × 2.5 lbs = 750 lbs
Railings: ~250 lbs
Total: ~2,050 lbs (about 1 ton)
What Can Go in the Dumpster?
✅ Accepted Materials
- Pressure-treated lumber (ACQ, CA, most CCA)
- Cedar, redwood, and other natural wood
- Composite decking (Trex, TimberTech, etc.)
- Vinyl deck boards and railings
- Metal fasteners, screws, nails, joist hangers
- Aluminum or steel railings
- Lattice, skirting, and trim
- Deck furniture (broken, non-salvageable)
❌ Prohibited Items
- Heavy concrete — may exceed weight limits; ask first
- Dirt and soil — requires separate disposal
- Paint cans — hazardous waste
- Stains and sealers — hazardous waste
- Batteries — from deck lights, hazardous
- Propane tanks — fire hazard
⚠️ Concrete Footing Disposal
Many dumpster companies accept limited concrete, but deck footings can be heavy. A typical 12" diameter × 36" deep footing weighs about 150 lbs. If you have 6+ footings, ask about weight limits when booking or dispose of concrete separately at a recycling facility.
Timeline: Deck Removal Project
| Deck Size | DIY Time | Dumpster Days Needed |

| Medium (200-400 sq ft) | 2 days | 5-7 days |
| Large (400+ sq ft) | 2-3 days | 7-10 days |
| Multi-level/elevated | 3-4 days | 7-10 days |
📅 Scheduling Tips
Book your dumpster for delivery the morning you start demolition. Most rentals include 7 days—plenty for weekend warriors. If building a new deck immediately, you can often schedule pickup and have the area cleared before materials arrive.
Frequently Asked Questions
How far in advance should I book a dumpster?
Book 2-5 days ahead for weekday delivery, 5-7 days for weekend delivery. Spring and fall are peak seasons for deck projects, so book earlier during these months.
Can I place the dumpster on my lawn?
Yes, but place plywood sheets underneath to distribute weight and protect grass. Driveways or paved areas are preferred. Check for underground utilities before placement.
Do I need a permit for a dumpster?
Usually no permit is needed if the dumpster is on your property (driveway). If placed on the street, most cities require a permit. Your dumpster company can advise on local requirements.
What if my deck has a hot tub?
Remove and dispose of the hot tub separately before deck demolition. Hot tubs contain motors, wiring, and insulation that require special disposal. The deck section under the tub may have reinforced framing that's heavier than standard.
Should I salvage any materials?
Deck boards in good condition can sometimes be reused for smaller projects. Cedar and redwood weather to an attractive gray and may be worth saving. Posts and beams are rarely worth salvaging unless they're clear cedar or hardwood.
What about the area under the deck?
Many decks hide years of debris underneath—leaves, trash, old landscaping fabric. Budget time for cleaning this area. A rake and wheelbarrow help. Don't put dirt or extensive organic debris in the dumpster.
