"We had Adirondack basement come out to waterproof our basement that got water whenever there was heavy rain or snow melt. The entire process was stress free and organized. Jeff was our Sales rep and was extremely informative about the entire process. The contractors that came out, Tim and Chris, were very friendly and worked efficiently. It was the easiest and stress-free experience I?ve had with ANY work for the house. I highly recommend Adirondack basement for any work needed for basements."

"Dave has gone above and beyond to help improve my home. I’ve hired him to complete numerous projects for me (painting, interior drywall work, demo rot, plumbing, installation) and his quality of work is excellent. I am beyond happy with the new water heater and bathroom shower faucet he selected within my budget. Dave is incredibly smart and always shows up with a smile on his face ready to get to work. I am thankful my neighbor referred him to me and would absolutely use his services again in the future. Thank you, Dave!"

"The installation of the hot water tank was great. I was not happy that they did not drain any water from the old tank, I believe that once they determined that they could not empty the water anywhere in the basement except outside they just left it. I am in my seventies and I had to do it the next day so I could move the tank."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

FAQs for sump pump or interior foundation drains installation projects in Nassau, NY

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.
