"Inspection of a previously installed sump pump system (primarily the sump pump). Inspection found that it seized up and wouldn't have functioned. Replacement made - and very fortunately - since when the pump is needed, it IS needed. It wouldn't have been good to have a flooded basement or have an upcoming flooded basement."

"Jared showed up on time and went right to work. Installing the back up water powered sump pump and new sump pump seemed quite involved to me, but Jared said it would be no problem to do it. I am completely satisfied with their service, and responsiveness. H. L. Bowman is now the only plumber I will use for all of my plumbing needs."

"Steven was the absolute best… arrived at the very start of only a two hour window, fixed the problem in about an hour. Very polite and courteous. I called three plumbers and he was the first to call me back and the only one who would give me a ballpark figure over the phone. The others wanted to come out and have a look for $70. even though I accurately described the job in detail. I’m thrilled to have a reliable plumber! A more than satisfied customer, Lora Harrigan"

"I selected Schede Plumbing for my conversion from an oil fired heating boiler to a gas boiler. My selection was based on known referrals in the Stamford, CT area from other well satisfied customers. I could not be more pleased, nor rate give enough praise and thanks to Lou Schede and his expert technicians. This was a major project for me and I was very anxious as to how the how conversion would take place. It would require draining the fuel tank, cutting it into manageable pieces and removing it from my basement. The idea of a gas conversion process was a bit scary to me but Lou Schede walked my through was would be involved, assessed what the heating requirement would be for my house, and selected a gas boiler which fit my needs perfectly. It was only two weeks from the time I first contacted Lou until the time the installation took place. My goodness, three Lou Schede trucks and four highly trained, professional and very polite technicians arrived at my house at 8:20 AM and by 3:00 PM my new gas boiler was installed, tested, and providing heat. Amazingly diligent workers worked very hard and did an beautiful installation. It was like a work of art in motion watching them work. The fuel tank was drained, cut up and removed. the oil fill pipes from outside to inside the basement were removed flush with both the interior and exterior walls and were cemented over. Beautiful, as if the pipes were never there. What also impressed me that whenever I had a question for Lou he was always there, immediately. No complicated voice menuing system. You want Lou, you call Lou, and you get Lou...immediately. This was very satisfying to me and he was a real pleasure to deal with. Absolutely top notch in every respect. The price for the installation was remarkably affordable....more that 6 to 8 thousand dollars less then competing firms. Incredible. He even cleaned the chimney, which was required by the city building code, applied for the permit at his expense. This was a thorough, comprehensive one shop job. Other firms required a separate electrician to hook up the thermostat, a separate firm to drain and remove the oil tank, and a separate firm to clean the chimney. Lou and his staff did it all!. One firm and he and his staff did it all. This is amazing. Lastly, he even accepted credit card for payment upon completion of the installation. I can go on and on. I have nothing but the best things to say about Schede Plumbing And Heating. They have my highest recommendation and are now my go to plumbing and HVAC company. Thanks Lou to you and your technicians for thoroughly well done job and an installation experience that was truly a pleasure."

"Nixon and his crew did an outstanding job gutting and rebuilding a very challenging bathroom in our house, which was built in the 1930s. We are very happy with the craftsmanship and the price, and it was a pleasure to work with them on this project from start to finish. I highly recommend this excellent contractor."

FAQs for sump pump or interior foundation drains installation projects in Darien, CT

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
