"We moved into a lovely house with many unsuspected problems including a very wet basement back in Nov of 2017. I did much research to find the best outfit to fix the problem. Ct Basement was not the cheapest. In fact, they were the most expensive by far. But, they were also the yardstick every other company compared themselves to. The job cost us 19,300. And we had to wait weeks for the work to start. BUT, everything went perfectly. As soon as the old debris was removed, I was shocked to find that the garbage of the old walls and flooring they removed had black mold under it. And, with its removal, my wife’s athsma cleared up and left town! They did a beautiful job, were very polite and the new installed basement, new sump pump with back up battery, perimeter trench, flooring, etc., all is great. They put a lot of work and material in to do this job with very skilled workmen who worked very hard. Sometimes you get what you pay for."

"We did some ourselves and we hired another contractor who was so detailed and spent lots of time at the estimate seeing what the actual problem was. He found the problem and proposed a solution which was NOT what M+M suggested or, proposed.

"I try to leave reviews on every business that I’ve been in contact with. I can say that this company, “Joe the Plumber” in CT (a Perras Family Co.) is simply awesome. I had used them years ago on my first house here in Glastonbury. They were great then. Maybe 10 years later (this morning) we woke up with no water on our ‘new’ home (24 years old), also in Glastonbury. I called the first number I had on my iPhone at 7am (spoke to a very professional person named Willy) and within 3 hours Wayne Perras (the service tech) & Co were here addressing the problem. After 24 years, the well pump gave out. It was in a 400 feet-deep well. They completed the job in 5 hours. I didn’t have to wait until Monday, which was one of my concerns. Wayne was very straight forward. No BS. Gave me the quotes. I agreed, since it sounded reasonable. I had changed the pump on my other house (not as deep & smaller pump) so I knew around how much it would cost. Wayne was great, knowledgeable and had a friendly and respectful disposition. I will certainly use them for another related project this Summer. I truly & honestly recommend this family company. It was a Godsend that the first number I had on my phone was for Joe the Plumber (the Perras)! THANKS GUYS!"

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