"Great, as always. Sila is outstanding. We have a service contract with them for our furnace and AC and they keep them in tip-top shape. And when we have an urgent or emergency situation (heating, cooling, plumbing, electrical), they're who we call."

"The technician/plumber didn't get the job done at all. He ended up breaking the shower valve and ended up placing a stopper on the line to prevent water leakage. In the process, he ended up taking 5-6 hours for a job that was finished by another plumbing company in 2-3 hours. It was a waste of my money as Village Home Services billed me $560, fixed nothing and broke the valve. Furthermore, their manager/owner asked me for another $2000 for them to come back and repair the damage they created. I got this job done for $800 from another plumbing company based out of Tyngsboro. I DO NOT RECOMMEND VILLAGE SERVICES. "

"The team that was sent smelled of weed, first thing I noticed. The work was done quickly, so that was good, but they didn't get an in process inspection and instead sent over an inspector more than a month after the work was done. The dirt that was displaced is just all over my yard now, and I have a bunch of big holes where they didn't pack any dirt. The company offered to fill them but I never heard back after that offer. As part of the work, they dug around the chimney, and it appears they caused it to break. They claim no damage was done, but I'm finding many pieces of concrete and brick strewn over my yard."

Customers say: Quick response

"Cody and his crew were amazing-- we had a complicated issue that required multiple visits and coordination with the city's engineers. Cody was professional, knowledgeable, and as dedicated to getting the job done right as if it had been his own home. His quotes were accurate and competitive, he and his crew were on time (and often stayed late!) and kept the work area clean and safe. We will never call anyone else!"

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