How much does it cost to install a sump pump?
A new sump pump installation typically runs $1,000–$3,000, depending on whether a basin must be cut into the floor and whether you add a battery backup. A simple pump swap in an existing pit costs far less.
Do I need a battery backup sump pump?
A battery backup keeps the pump running during a power outage — often exactly when you need it during a storm. It is worth considering if your basement floods, but it should be your decision, not an automatic upsell.
How long does a sump pump last?
Most sump pumps last 7–10 years. If yours is older or cycling constantly, replacement is cheap insurance against a flooded basement.
