"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"

"This company was recommended to me by a plumber that I know. They showed up on time, got right to work, spent the time answering my questions and making sure I understood the type of cesspool system I had and how to maintain it. They were able to find the cesspool within about 5 minutes, almost just by looking at the lawn. Pumped it, aerated it, applied chemicals. Great job, highly recommended!"

"They did an excellent job. KTG were the first to reach out when I submitted my project request. They arrived earlier than scheduled. They completed a walkthrough and listened to my concerns. I loved the cleaning products they used, the apartment smelled great. I would use their services again and recommend to friends. They are reliable and professional. Thanks again!"

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