Basement Cleanout Dumpster Size Guide
Basement cleanouts often involve water damage, mold, and decades of stored belongings. Learn how to choose the right dumpster size for wet materials, contaminated items, and heavy debris disposal.
Small Basement Cleanout?
Two Types of Basement Cleanouts
Dry Storage Cleanouts
Recommended: 10-20 yard dumpster
Weight: Normal limits apply
Water Damage Cleanouts
Recommended: 20-30 yard dumpster
Weight: Plan for 2-3x normal weight
✅ Dry Storage Cleanouts - Common scenarios
- •Normal storage item removal
- •Old furniture and appliances
- •Pre-move decluttering
- •Seasonal organization projects
- •Estate cleanouts (no water damage)

Water Damage Weight Factors
Water absorption dramatically increases material weight. Understanding this helps you choose the right dumpster size and avoid costly overage fees.
| Material | Dry Weight | Wet Weight | Impact |
|---|---|---|---|
| Drywall (4x8 sheet) | ~57 lbs | ~120-150 lbs | 2-3x heavier |
| Carpet (per sq yd) | 5-20 lbs | 15-60 lbs | 3x heavier |
| Insulation (per cu yd) | 100-200 lbs | 300-500 lbs | 2-3x heavier |
| Furniture/Wood | Normal weight | 1.5-2x weight | Moderately heavier |
💡 Weight Limit Reality Check
Dumpster Sizing by Project Type
10-15 Yard: Small Dry Storage Cleanouts

Cost range: $450-$800 | Weight limit: 3-4 tons
Timeline & Cost Optimization
Water Damage: Act Fast
Time is critical for water damage to prevent mold growth within 24-48 hours.
- • Schedule dumpster for immediate delivery
- • Remove wet materials within 24-48 hours
- • Document everything with photos
- • Save receipts for insurance claims
Dry Cleanouts: Plan Ahead
Standard storage cleanouts allow more time for sorting and donating.
- • 7-10 day rental periods typical
- • Sort items: keep, donate, dispose
- • Donate salvageable items first
- • Coordinate with family schedules
💰 Cost Optimization Tips
- Donate furniture and items before disposal to reduce volume
- Separate recyclable metals for potential scrap value
- Size up rather than rent twice - second rentals are expensive
- For water damage, consider insurance reimbursement for disposal costs
- Load heavy items first, fill gaps with lighter materials
Final Recommendations
For dry storage cleanouts: A 20-yard dumpster handles most basement cleanouts perfectly. Small basements (under 800 sq ft) may only need 10-15 yards.
For water damage: Plan for heavier weight due to water absorption. A 20-yard works for minor water damage, but extensive flooding may require a 30-yard dumpster to avoid hitting weight limits early and incurring overage fees.
Safety first: For sewage backup, extensive mold, or structural concerns, hire professional remediation services. They have proper equipment, training, and disposal methods for contaminated materials.
