Four commitments that separate a properly trained sump pump installation crew from a generalist showing up with a truck and a hope.
Technicians calculate gallons-per-minute inflow before recommending a cast-iron, submersible, or pedestal pump.
A failed primary pump during active weather gets priority dispatch — most New London, WI service areas see a technician within hours.
Every quote breaks out pump unit cost, basin/pit work, discharge line routing, and labor separately, in writing before installation.
Primary pumps fail silently more often than people expect — a battery backup with a water-sensing alarm catches that failure before it becomes a flood.
Each service below is scoped specifically to sump pump installation, not a generic waterproofing menu with the name swapped in.
We install cast-iron or high-torque submersible pumps sized to your basin's actual inflow rate, not a generic big-box unit. Pit liners are set in washed gravel for stable seating and long-term reliability.
We size the backup to match your primary pump's capacity, not a mismatched unit that can't actually keep pace during a real event.
We evaluate your water pressure and local code requirements before recommending this system over a battery-based alternative.
In colder months, discharge lines are checked for freeze-prone routing and can be fitted with a freeze-guard fitting to prevent backup during winter storms.
A standalone water-sensing alarm alerts you the moment water rises above a safe threshold in the pit, even if the pump itself is functioning.
Here's the path from your call to a fully installed and load-tested pump.
Tell dispatch whether this is a new installation, a failed pump replacement, or a backup system upgrade, and the right equipment gets loaded before the truck leaves.
Trucks stock commonly needed pump models, basin liners, and battery backup units, so most replacements are completed in a single visit.
We calculate your basin's actual inflow rate and recommend pump horsepower and switch type accordingly, explained in terms you can evaluate.
Every installation is tested under load before the technician leaves, confirming the float switch activates and the pump clears water at the expected rate.
