What causes water damage in basements?

  • Sump pumps can break and the water in retention tanks can overflow, damaging items in basements
  • Heavy rain can cause municipal sewers to overflow, which could then cause water to back up through toilets, showers, washing machines or floor drains
  • Heavy rain can cause ground water build-up that seeps in through basement windows
  • Tree roots can grow into and clog foundation drains, causing water to seep into basements through the foundation

How to prevent water damage

  • Direct gutter runoff away from the house
  • Make sure the ground around your house slopes away so that water doesn’t accumulate
  • Repair any cracks in the foundation
  • Make sure the plumbing system in your basement includes:
    • At least one fully functional backwater valve
    • A water discharge pump connected to a retention tank
