What we do

Sump pump and basement water services

Whether your pump quit in the middle of a storm, it's ten years old and you'd rather not find out the hard way, or your basement takes water every spring, we handle the whole picture — pump, basin, discharge, and the drainage around your home.

New sump pump installation

For homes with no pump at all — we set the basin, size the pump to your water inflow and lift, and route discharge so the water actually leaves the property instead of circling back to the foundation.

Sump pump replacement

Aging, noisy, short-cycling, or burned-out pumps replaced with a properly sized unit, new check valve, and serviceable unions so the next swap is quick.

Battery backup sump systems

Storms take the power out at exactly the wrong moment. A battery backup pump keeps pumping when the utility drops, and an alarm tells you before water reaches the floor.

Sump pump troubleshooting

Pump running nonstop? Not turning on? Humming but not moving water? We test the float, check valve, discharge line, and power circuit before recommending anything.

Basement water & flooding solutions

Sometimes the fix is drainage, not a pump — clogged storm lines, blocked underground drain piping, failed discharge, or grading. We diagnose the source first.

Diagnose first, sell second

Water in a basement doesn't always mean you need a new sump pump

This is the honest part most sump pump ads leave out. Basement water has several possible causes, and a pump only addresses some of them. Installing equipment before identifying the source is how homeowners end up with two pumps and the same wet floor. Here is what we actually check.

Failed or undersized sump pump

The pump may be original to the house, too small for the inflow, or mechanically worn. A pump that can't keep up during a heavy rain looks like a flooding problem but is really a capacity problem.

Clogged or obstructed storm drainage

Storm drains, area drains, and catch basins that no longer carry water away leave it sitting where it can find its way toward the building.

Clogged exterior or underground drain piping

Buried downspout lines and yard drain piping fill with silt, roots, and debris. Once they're blocked, roof and surface water discharges next to the foundation instead of away from it.

Poor drainage around the property

Grading that slopes toward the house, settled walkways, planting beds holding water, and downspouts terminating at the foundation all push water where you don't want it.

Failed sump discharge piping

A cracked, disconnected, frozen, or back-pitched discharge line means the pump works and the water comes right back in. This is one of the most commonly missed causes.

Power failure during a storm

The heaviest rain and the power outage often arrive together. Without a battery backup or a secondary pump, the basin fills with no pump running.

Groundwater overwhelming the existing system

Rising water tables and spring thaw can exceed what a single pump and single basin can handle, even when the equipment is healthy.

Plumbing leaks mistaken for groundwater

A weeping water service, condensate line, failed water heater, washing machine hose, or leaking waste line can look exactly like seepage. We rule this out before recommending a pump.

If the cause turns out to be a blocked storm line or a failed discharge pipe, that is what we'll recommend repairing — our professional drain cleaning and camera inspection work exists for exactly this reason. If water has already damaged finished space, our water cleanup division can handle extraction and drying in the same visit.

How it works

Our four-step approach

1. Find the water's source

We inspect the basin, pump, float, check valve, and discharge line, then look outward: storm and area drains, buried downspout piping, grading, and any plumbing that could be leaking nearby.

2. Test, don't guess

Camera inspection of underground drainage where it's warranted, flow testing the discharge, and confirming the pump actually moves water under load rather than just humming.

3. Recommend the right fix

That might be a new pump, a backup system, a repaired discharge line, cleared storm drainage, or a combination. If a pump isn't the answer, we say so.

4. Flat-rate price, then work

You approve a written flat-rate price before we start. No hourly clock, no surprise additions once the truck is in your driveway.

Storm insurance

Battery backup sump pump systems

In Connecticut, the storm that fills your basin is often the same storm that takes the power down. A primary pump with no backup is only protection while the lights are on. A battery backup system adds a second pump powered by its own sealed battery, sized to run for hours on its own, plus an alarm so you know the moment it takes over.

  • Second pump that runs when utility power drops
  • Sealed maintenance-free battery with charge monitoring
  • High-water and pump-failure alarms, including Wi-Fi models
  • Battery replacement roughly every 3–5 years so it works when needed
  • Works alongside your existing primary pump in most basins
  • Recommended for finished basements and stored valuables

Questions homeowners ask

Sump Pump & Basement Water FAQ

Do I automatically need a sump pump if I have water in my basement?

No. Water on a basement floor tells you water is getting in — it does not tell you why. The source should be identified first. We look at where the water appears, how it behaves during rain, the condition of the existing pump and discharge line, the storm and exterior drainage, and whether there is any plumbing leak in the area. In some situations, correcting a clogged or malfunctioning drainage system solves the problem without installing another pump. Adding a pump before knowing the cause can leave you with the same wet basement and a new invoice.

Can a clogged storm drain cause basement water problems?

Yes. Storm drains, area drains, catch basins, and buried downspout piping exist to carry water away from the structure. When any of that is blocked with silt, roots, leaves, or a collapsed section, the water it was supposed to carry has nowhere to go, so it accumulates around the building and can work its way inside. Clearing and camera-inspecting that drainage often reduces or eliminates basement water — and it is a very different repair from installing a pump.

How long does a sump pump usually last?

Most primary pumps run about 7 to 10 years, less if they cycle heavily or sit in a basin with sediment. Battery backup systems need their battery replaced roughly every 3 to 5 years, which is why a backup installed a decade ago is often not a working backup today.

What are the warning signs of a failing sump pump?

Running constantly or cycling every few seconds, unusual grinding or rattling noises, visible rust or scale in the basin, water standing in the pit while the pump runs, tripping breakers, a float that sticks, or a pump older than about ten years that has never been tested. Any of those is worth a look before the next big storm rather than during it.

What happens during a power outage?

A standard sump pump stops. If the storm dropping your power is also the storm filling the basin, that is when finished basements flood. A battery backup pump runs on its own sealed battery for hours, and a water alarm alerts you if levels keep rising. Homes with a generator can also be wired so the sump circuit is covered.

How should a sump pump be maintained?

Test it a couple of times a year by pouring water into the basin and confirming it starts, pumps, and shuts off cleanly. Keep the basin free of gravel and sediment, verify the check valve holds, confirm the discharge line is intact and pitched away from the house, and replace backup batteries on schedule. We can handle this as an annual inspection.

When does a second sump pump make sense?

When a single pump genuinely cannot keep up with peak inflow, when the basement is finished or stores something valuable, or when the home has a history of flooding during heavy rain. A second pump set at a higher float level, or a battery backup pump in the same basin, adds real redundancy. It only makes sense once we've confirmed the drainage and discharge are sound — otherwise you're doubling pumps against a blockage.

How do you decide what my home actually needs?

We start with a diagnostic visit. Our $125 service charge covers a full assessment of the pump, basin, discharge, and surrounding drainage plus a detailed written estimate. The fee is waived if you hire us for the work. You get a flat-rate price approved before anything begins — and if the fix is drainage rather than a pump, that is what we'll tell you.
