Basement Sump Pump Installation Process
We start with a thorough assessment of your basement’s water issues and current drainage situation. This tells us exactly what type of sump pump system will work best for your specific conditions.
Next, we excavate the sump pit in the right location – usually the lowest point where water naturally collects. We install the pump, connect the discharge piping, and ensure proper electrical connections with GFCI protection.
Finally, we test the entire system to make sure it’s working correctly and show you how to maintain it. You get a system that’s ready to handle whatever weather comes your way.
