Sump & Well Pump Services in Northern Virginia & DC

A dead sump pump costs a Northern Virginia basement far more than the pump itself. We service and replace sump, sewage ejector and well pumps, test the float and check-valve, and give you the figure before the storm arrives.

Common questions about sump & well pump services

What does a new sump pump cost around here?
A 1/2 HP cast-iron sump pump fitted starts at $685. A sewage ejector pump runs $1,250 and a submersible well pump begins at $2,150 depending on depth.
Do I need a battery backup?
In this area, yes — our worst basement flooding happens in summer storms that knock the power out. A battery backup system adds $895 and runs for hours without utility power.
How long should a sump pump last?
Seven to ten years on average. If yours is older than that and runs often, replacing it before the next storm is far cheaper than drying out a finished basement.
