# Basement flood cleanup: container, weight and what you cannot throw in

Direct answer
A 20 yard container. Water is the whole story. Saturated drywall, carpet, padding and stored cardboard can weigh several times their dry weight. Expect $325 to $775 for the rental, and check the material list below before you start — this job produces 5 things worth verifying.

**Recommended**: 20 yd³

**Constraint**: Weight-limited

**Weight limit**: 2–4 tons

**Typical cost**: $325–$775

## How much debris this job produces

Volume looks like a 15 yard job and weight often behaves like a 30. Assume you are near the tonnage cap and ask for a higher allowance up front rather than arguing about overage later.

## Why this size and not the next one

Water is the whole story. Saturated drywall, carpet, padding and stored cardboard can weigh several times their dry weight. The 20 yard is the most-rented size in the country and it is still 4 feet tall, so you can throw over the side instead of walking the door. That combination is why it is the safe default.

Also reasonable: [15 yd³](https://dumptergod.shop/sizes/15-yard-dumpster/), [30 yd³](https://dumptergod.shop/sizes/30-yard-dumpster/).

## What goes wrong on this job
- Work fast — every day the material sits, it gets heavier and more contaminated
- A mold-contaminated mattress is specifically exempt from the Massachusetts mattress ban, which makes a flooded basement one of the few times that ban does not apply
- A flooded basement is where paint cans, fuel and pesticides get discovered floating. Those go to hazardous waste collection, not the container

## Materials from this job that need checking

- Conditional ### Drywall and gypsum board Accepted in general C&D loads in most of the country, but clean gypsum wallboard is banned from disposal in Massachusetts, where it has to be separated for recycling.Massachusetts: Clean gypsum wallboard is a banned material. Loads containing it can be rejected at the transfer station. (310 CMR 19.017)We have not verified this material against your state’s own regulator. That means unknown, not allowed — check with your state before you load it.Varies by state Construction debris MA
- Accepted ### Carpet and padding Accepted. Roll and tie it — loose carpet wraps around the container walls and stops the load from tipping out cleanly, which is how you end up with a dump-out fee.Hauler policy Construction debris
- Conditional ### Fiberglass insulation Fiberglass and mineral wool are accepted. Vermiculite insulation in a pre-1990 attic is a different question — it may contain asbestos and must be tested before anything touches it.Hauler policy Construction debris
- Conditional ### Mattresses and box springs This is the clearest case on the site of a question with a different correct answer depending on where you live. Most haulers take a mattress in a general container and add a per-item charge because mattresses wrap around landfill compactor drums. In Massachusetts they are banned from disposal outright.Massachusetts: Banned from disposal since November 1, 2022, including any foundation or box spring. The ban has a real exception: a mattress contaminated with mold, bodily fluids, insects, oil or hazardous substances is excluded, so a genuinely soiled mattress can still be disposed of. (310 CMR 19.017)We have not verified this material against your state’s own regulator. That means unknown, not allowed — check with your state before you load it.Varies by state Household MA
- Conditional ### Paint and stain Liquid paint is not allowed in a container anywhere — it is a liquid, and oil-based paint is a hazardous waste. Fully dried latex paint in an open can is a different material and is commonly accepted, because what is left is solid pigment.Federal rule Hazardous and regulated
