Basements in Jefferson County often take water in the spring because snowmelt runs into ground that is still frozen and looks for the lowest route into the house. A sump pump that cannot keep up, or one that failed during the thaw, is a common reason. Shut off power to a wet area only if the panel is dry.
Key takeaways
- Snowmelt in March and April runs over frozen ground, so the water finds the foundation instead of soaking in.
- A sump pump has to keep up for days in a thaw, and a failure during the thaw is a common cause of basement water.
- The first sign is often a damp line on a lower wall, not a puddle.
- Locate the entry point before anything is pumped, dried or removed.
What happens when snow melts over frozen ground in Jefferson County?
Frozen ground cannot absorb meltwater, so it runs toward the house and finds the wall, the floor joint or the window well. The sign is usually a damp line low on the wall.
The National Weather Service normals for the nearest stations show heavy snowfall through the winter, with a mean January temperature in the low twenties Fahrenheit at Milwaukee. That means a thaw can come after weeks of frozen ground, and the water has nowhere to go.
Basements on the lowest part of a lot, or beside a slope, take the most. The crew checks the wall nearest the slope, the floor joint and the sump pit.
What should I do when a basement starts to take water in a thaw?
Keep out of standing water near outlets and appliances, check the sump pump if there is one, and call before the water has been standing for days.
Turn off power to the wet area only if the panel is dry and you can reach it without standing in water. Photograph the water and the wet line on the wall before moving anything.
A technician will extract the standing water, trace where it came in and take moisture readings on the framing. The drying plan follows from those readings.
Frequently asked questions
Is every spring basement leak a sign of a bigger problem?
Not always. A thaw can push a small amount of water through a wall. The readings show whether the framing is holding moisture, which decides how much drying is needed.
What should I do if my sump pump failed during the thaw?
Turn the pump off at the breaker only if the area is dry, clear the pit of debris if you can do so safely, and call (833) 490-5225. A technician will check the pit and the discharge line.
