What Can Cause a Basement to Flood?

Basement floods occur from either an internal source, like a broken pipe, or an external source, like a natural disaster. The most common causes of a basement flood are frozen pipes, heavy rains, an overflowing toilet, a sump pump failure, a leaking hot water tank, and improperly installed downspouts. However, basement flooding can occur after a failure in any of the following:

  • Pipes and water supply lines
  • Landscaping sloping
  • Foundation structure and sealing
  • Weeping tile
  • Drainage systems
  • Downspouts
  • Gutters
  • Hot water tank
  • Sump pump
  • Egress windows
  • Door seals

While some of these causes may be obvious to identify (for instance, water spraying out of a broken pipe), others may be more difficult to identify. If you come home to a flooded basement and aren’t sure what the cause was, call an emergency water restoration company to get the water cleaned up safely. The professionals will turn off the water and electricity to your home to enter the flood waters with safety in mind and look for a cause. They can pump out the water and get the area dried up quickly to try to prevent mold growth. If a plumbing failure caused they flood, they can recommend a local plumber (or may even partner with a trusted plumbing company) to get the root cause fixed as part of their restoration work.
