"After Hurricane Sandy, we had our sump pump system with a battery backup expanded a few years ago with additional curtain drains added. The price was reasonable and they did not try to sell extras that other companies tried to sell. We have the system and battery serviced once a year. They keep to their appointments times."

"It went very smoothly. There was one minor hiccup that wasn't discovered until after 9pm on the evening of the installation, but we called the 24-hour service line and within 20 minutes, there was a tech back at our house to fix the issue. I would contract H L Bowman to do work for us again in a heartbeat."

"I really liked CT Basement systems. The sales rep walked me through the process of the basement SaniDry I had installed. When the installer came it turned out that I didn’t need all of the duct work and I was able to save a few hundred bucks. The installer was very professional, neat and helpful . I definitely will hire this company again. Customer service even followed up with me a few days later and had to remind me to register the system (good thing because I had forgotten)."

"At the end of the service (When the serviceman charge me), he suddenly started saying ours was not furnace but boiler so can't apply Angie's list offer $69 and tried to charge full price $149. That was not nice. Even though we end up hiring him for extra service and paid another $400 service. I had to have very long discussion with the office to rectify the issue as the office manager also said it's not applied for boiler (even though tune up process is same or less!). Finally she accepted to take Angie's list offer price. To add, this guy said $295 for extra service we asked when he started work but when he charged me he said "oh it's $395 I never said $295!" Well I was too tired to argue with them so I paid but this way they made up for the $80 discount through Angie's list. but it gave us impression of bait&switch."

"They came out on a weekend and we're our saving grace during one of the most frustrating experiences we've had in this house. We couldn't use any plumbing without flooding the basement with sewage, it was early stay at home days, and we felt like we would go mad. They showed up and gave us an price for replacing the broken pipe, and set in to work. They worked for the entire weekend essentially, staying extremely late at night and showing up early the next morning, and at one point driving far out at night to get supplies since their usual local place was closed (again, quarantine time) . The reason it took so long was because after opening up the floor to get to the end of the pipe to replace it they found more damaged pipes, and replaced those as well. By the end of it they had spent the entire weekend on a job they expected to only last an afternoon, had charged us not nearly enough for the amount of work they did, and fixed a leaking bidet we had for free for good measure. They also advised us to do camera scan to look for any other problems, which they couldn't do until the water drained out, and even did an initial mop of the basement (which, remember, sewage flooding). I'm honestly half convinced these people are magic helpful brownies or something, it's unreal how helpful they were! Somehow our drier which has not succeeded in drying clothes for over a year has started working in a single cycle since they left, despite the fact they didn't even do anything with it, and in fact specifically said they don't do driers and offered to recommend someone else when we mentioned it. Suffice to say, I cannot recommend them highly enough"

"Extremely satisfied.  Company was responsive (My initial call to them was on Xmas Day when I noticed the sewer backed up in my back yard).  They called me back immediately and  agreed to send someone to look at it the next day (after ansering some questions, we agreed it was not an emergency) - they came the next day as promised and even called prior to their arrival.  The plumber assessed the situation and took pictures to send back to Larry.  I spoke with him and agreed to have them come back on Monday when the equipment  needed to address would be available (needed an extra long hose and camera set up given the location of the cleanout cup).  Each time dealt with the company (Larry) he would call to let me know status and options.  On the day they came, Larry and his associate were at my home at the time promised.  Spent nearly 3 hours and all is well.  So although a bit pricey, well worth it given the responsiveness and professionalism of the company.  Would highly recommend them for any of your plumbing needs.

FAQs for sump pump or interior foundation drains installation projects in Greenwich, 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.
