"They did an excellent job. Put a threshold drain in front of a sliding door to my patio. They had to remove pavers, install a 4 inch pipe across the lawn and replace the pavers and sod. Hard workers did a really good job."

"When I first met Stavros, he discovered damage that another company completely missed. His inspection was thorough and he explained the situation so we could easily understand what was happening and what we needed to do to repair it. He and his crew then did a very thorough job repairing our concrete foundation that had cracked and was sinking due to problems with the subsoil, as well as leveling the concrete slab in our basement. He took care not to damage our property, and even maneuvered his equipment under our deck so we didn't have to remove it to complete the repair. He and Athena genuinely care about their customers, and were empathetic and kind throughout what was a difficult experience for us as homeowners. I would not hesitate to recommend Arta to anyone who needs foundation work."

FAQs for sump pump or interior foundation drains installation projects in Hillsborough, NH

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.
