"They were great to work with and came in with a competitive price. They were clean and efficient. Had 125 feet of French drains installed through our basement with 2 sump pumps done in one day. Came back a few days later to complete what was needed outside the house."

"Great! The workers are very professional and punctual. They installed a tankless water heater. They cleaned everything up when they were done and then explained how it worked and how to maintain it throughout the years so it would work better. I highly recommend this company."

"They arrived early the day of scheduled appointment and responded immediately to assess my problem the prior day. They were there when I needed them while other companies were either too busy or called the next day of my inquiry."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"We had a new washing machine installed by Home Depot and when we started our first load the entire full washing machine of water flooded down thru the floors to the kitchen. We called PipeWorks for an emergency visit because we thought a pipe burst. Mario from PipeWorks came and found that Home Depot did not attach the water drain pipe securely on the back of the washing machine – it had popped off the back. So $404 later Mario saved the day. He spent alot of time testing the machine at different cycles to make sure there were no more leaks. I would highly recommend PipeWorks & Mario for any regular or emergency plumbing project. But shame on Home Depot for their shoddy installation."

"Hired Joseph and Sons for a basement French drain installation. Angelo and team were easy to work with, professional, and communicated very well. Very fair on price as well. Our basement was already partially finished and they were great in that they did the demolition required, drain and pump install, and refinished the basement (drywall, flooring, etc.). Really nice to have a one stop shop. Will certainly use them in the future!"

"The sinks are draining well. The stopper is fixed. The toilet was unclogged, but got clogged again the next day. Had to pour Ajax, and let it sit overnight to unclog the toilet again. That is the reason I have given a B, rather than an A"

FAQs for sump pump or interior foundation drains installation projects in Dover, NJ

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.
