Call 414-262-5777 — we'll diagnose it and give you a straight, written quote.

Your sump pump is the one thing standing between your basement and a flooded floor. When it won't turn on, runs nonstop, cycles every few minutes, makes grinding or humming noises, or quits during a storm, we find the cause and fix it — float switches, check valves, frozen or blocked discharge lines, and battery backups that should have kicked in but didn't.

We also tell you honestly whether a repair will hold or whether it's time for a new pump and basin. A reliable pump with a working backup is the cheapest insurance you can buy against a finished basement full of water.

A Pump Failure Costs More Than the Pump

Around New Berlin, a sump pump usually fails at the worst possible moment — during a heavy storm or the spring thaw, when the power's flickering and the groundwater is already high. A pump that's been cycling oddly or making noise is telling you it's near the end, and waiting it out means betting your finished basement on a part that's already struggling. Swapping a tired pump or adding a battery backup before the next big storm is a fraction of what one flooded basement costs to clean up.

Battery backup installation

A backup pump that runs when the power's out, so a storm doesn't flood your basement.

Replacement & new installation

When repair won't hold, we size and install a new pump and basin correctly.

Why This Happens in New Berlin

Southeastern Wisconsin's sump pumps work hard. The glacial till under New Berlin holds a lot of heavy clay that traps water against basement walls, so groundwater stays high long after a storm passes. Spring snowmelt and intense summer thunderstorms — the region has seen severe flooding from storms like those in July 2010 and August 2025 — can overwhelm a pump in hours.

On top of that, our winters freeze the ground several feet deep, and a discharge line that exits too close to the house or isn't pitched right can freeze solid and block the pump exactly when you need it most. Most homes here were built from the 1950s through the 1990s, so the original sump pumps and basins are decades old and often undersized for today's storm intensity.

Prevention Tips

Test your sump pump before spring thaw and storm season — pour a bucket of water in the basin and confirm it kicks on and empties. Make sure the discharge line exits well away from the foundation and stays clear and unfrozen in winter. Keep the basin free of debris so the float can move freely. Clean your gutters and extend downspouts away from the house so less water ever reaches the pump. And if you have a finished basement, install a battery backup before the next storm, not after.

Sump Pump Repair FAQ

How do I know if my sump pump is failing?

The warning signs are a pump that won't turn on at all, one that runs nonstop, one that cycles every few minutes, strange grinding or humming noises, and a basin that's dry when it should be full or full when it should be empty. If your pump quit during a storm and your battery backup didn't kick in, that's a failure you need looked at before the next storm.

Should I repair or replace my sump pump?

It depends on the failure and the pump's age. A stuck float switch or a failed check valve is a cheap repair on an otherwise good pump. A pump that's older than about seven to ten years, or one with a burned-out motor, is usually better replaced — and a new, properly sized pump with a working backup is the cheapest insurance you can buy against a flooded basement.

Why does my sump pump run even when it's dry out?

If it runs constantly with no rain, the most common causes are a stuck float switch, a failed check valve letting water flow back in, or a high groundwater table on your lot. Some homes in low-lying areas near the lakes and rivers around here sit high enough in groundwater that the pump runs often year-round — that's normal, but the pump and backup need to be up to it.

Do I really need a battery backup sump pump?

If you have a finished basement or anything stored on the basement floor, yes. Power outages and severe storms tend to arrive together, and a standard pump is useless without electricity. A battery backup pump runs when the power's out and gives you time to get through the storm.
