"Mario of Mario’s Faucet and Toilet Repairs in Bayshore NY was courteous and efficient. He cleared the clogged pipe and got the plumbing back in working order. He’s been doing this for 10 years so he’s very experienced. I think the price was very fair for the work done. I would highly recommend him for plumbing and drain issues. Thank you Mario!"

"Billy and his crew were an absolutely pleasure to work with. They exceeded my expectation to replace my boiler and hot water heater along with associated piping in record time working in concert with the GC to complete all work in 3 days. The finished work was neat and clean correcting errors with my original installation. All debris was removed each day. He ensured I was satisfied, kept me informed of the progress and what to expect. Upon leaving he made recommendations to have all my air valves replaced in my radiators and encouraged me to call with any questions. I appreciate the care he and his crew took with my home."

"I have to say that in this day and age, when so many service providers either don't call back after you leave a message, or they don't follow through on appointments (even here on Angi), it was a PLEASURE to deal with Cs Water Works. From start to finish he was completely conscientious about doing the job thoroughly. Not only would I definitely use him again, I would recommend him to anyone needing service. I chose him because I saw he had a 5 star rating and I am happy to see to it that I also add my 5 star review. He deserves it!"

"There was a crack in the basement wall from top to bottom that was leaking water onto floor after a heavy rain. James suggested several options but suggested the inexpensive crack filler and sealer first. I had other companies give me estimates and he was by far the cheapest for the same exact work. They arrived on time, cleaned up and are very nice and helpful. Very knowledgeable about waterproofing."

"I recently had a roof repair done, and I couldn?t be happier with the results. The team at dryshield arrived on time, were professional, and explained every step of the process in detail. They identified the issue quickly and provided multiple options before deciding on the best fix for my situation. The work was completed efficiently without causing any disruption to my daily life. They cleaned up thoroughly after finishing, and the materials used looked high quality. , and I?ve had no leaks or water damage since the repair. What impressed me most was their attention to detail ? They also offered a clear timeline and kept me updated throughout the process. I would highly recommend them to anyone needing roof repair or replacement. I plan to hire them again for future home improvement projects. Rating: ????? Recommendation: 100% ? I?ll definitely use them again"

"We used ACM 7 years ago to install a French Drain and sump-pump for the southern side of our lower level. It solved our water leak problems. This past week we used them again to install a similar system on the northern side of our lower level.

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