"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."

"Connecticut Basement Systems prides themselves on their superior customer service, and they really live up to that. Their communication, quality of products and service, and attentiveness to customer needs is unsurpassed. Here are a couple of examples of how they go the extra mile for a satisfied customer: They installed their basement drainage system around my existing heating oil tank, but as I'm planning to convert away from oil this summer, they offered to come back AT NO EXTRA CHARGE once the tank is removed, to reroute the drainage system. Also, I was scheduled for a 3-day project, which included the replacement of some flooring in my basement. On the day the project began, we reconsidered the need for the flooring, and asked if we could cancel that portion of the job. They could not have been more accommodating to that adjustment, and made the change with no questions asked or negative attitude, even though it significantly lowered the price of the project and eliminated a whole day of scheduled work on 2-days' notice. That sort of total customer dedication is rare. I recommend them highly."

"They looked at the sump pump and gave me a choice of ways I could solve my problem. They repaired and showed me and explained the repair. They were very neat and cleaned up after. I would recommend them to anyone 👍"

"Easy process from quote to work complete. The crew worked on a few small projects -- fixed a damaged wall, repaired flooring, and installed a new toilet."

"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.

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