What basement flood restoration includes
- Water extraction with truck-mount or portable extractors, priced per square foot.
- Flood cut: wet drywall is cut 2 feet up and removed, along with wet insulation and baseboards.
- Carpet and pad removal. Pad almost always comes out; carpet can sometimes be saved with clean water.
- Antimicrobial treatment on everything that stays.
- Commercial drying: air movers and LGR dehumidifiers, with daily moisture readings until the structure is dry.
What makes basement water damage cleanup cost more
- Finished vs. unfinished. A finished basement has drywall, insulation and flooring that trap water, so tear-out and drying cost more.
- Sump pump failure vs. sewer backup. Groundwater from a failed sump is usually clean or grey; a floor-drain backup is sewage and is priced as Category 3. See sewage cleanup cost.
- How long it sat. After 48 hours the risk of mould goes up and more material has to come out.
- Laminate and vinyl plank. Water gets trapped underneath, so it usually has to be lifted.

Will insurance cover my basement flood?
A burst pipe or failed water heater is usually covered. Sewer backup needs a sewer backup endorsement, and water from outside (overland flooding) needs an overland water endorsement. We document the cause and bill your insurer directly. Read does home insurance cover water damage in Ontario?
