Primary sump pumps sized for Dane County water tables, battery backup systems for power-outage protection, and full pit replacements when the existing basin is undersized or failing.
Sump pump installation pricing (reference ranges, not quotes): a standard primary pump install usually runs $450 to $900, the common range with battery backup is $1,200 to $2,500. Full pit replacement runs higher because of slab demo and re-pour. 5-year install warranty on labor and discharge plumbing.
Just so it is clear: those numbers are reference ranges to help you plan, not a firm quote. Horsepower, pit condition, discharge run length, and whether a backup goes in all swing the price. Call us and we will scope your pit for free, then put the actual number on paper.
Free inspection for any homeowner who is not sure whether the existing pump is failing or just running often. We watch the pump cycle for 20 minutes during the inspection, measure the pit depth and the inlet elevation, check the discharge plumbing for code compliance, and pull the pump amperage with a clamp meter if there is any doubt about the motor. A pump-only swap is two to three hours on a single visit. A battery-backup add-on is another two hours. A full pit replacement runs a day on site because of the slab demo and re-pour. The install carries a 5-year labor warranty, and we coordinate the manufacturer warranty on the pump itself if it ever needs replacement inside the warranty window.
A standard primary sump pump install usually runs $450 to $900. Adding a battery-backup pump brings the common range to $1,200 to $2,500. Full pit replacements (when the existing pit is undersized or failing) run higher because the work includes slab demo and re-pour around the new basin. These are reference ranges, not quotes, the firm number comes after a free inspection.
In Dane County, yes for any home where a basement flood would be more than a nuisance. The 2019, 2022, and 2024 storm seasons each produced multiple power outages of 4-plus hours during heavy rain events. A primary pump runs on 120-volt house current and stops the moment the power goes. The battery backup runs on a deep-cycle marine battery and buys 8 to 12 hours of pumping after the lights go out, which covers most outage windows.
For most Madison-area homes, 1/3 HP is enough on the primary if the pit is sized correctly and the drain-tile run is short. 1/2 HP is the right call on Verona and Sun Prairie homes where mature landscaping has raised the local water table over the last decade, or on any home with a long discharge run. We size off the pit volume and the cycle frequency we observe during inspection, not off a generic recommendation.
Most jobs are pump-only replacements, which means we lift the old pump out, clean the basin, set the new pump, replumb the discharge with a code-compliant check valve, and you are back in service in two to three hours. Pit replacement only comes up when the existing basin is cracked, undersized, or set at the wrong elevation. The inspection tells you which is required.
Yes, every install. Code-compliant check valve at the pump, properly sized PVC discharge to the exterior, anti-freeze loop at the exterior penetration to prevent backflow icing through the Madison winter, and a discharge termination far enough from the foundation that the water does not cycle right back into the drain tile. We do not leave any of that to a follow-up trip.
5 years on the primary pump, 2 years on most battery backups, manufacturer warranty terms. Our install carries a separate 5-year warranty on the labor and the discharge plumbing, transferable to a new homeowner once. We replace pumps under the manufacturer warranty as part of the install warranty service.
