"One of the best experiences we had in a long time. Our sump pump broke on Saturday and the water level was high. We found done right today from Angie’s list and called them first. They told us they are completing another job and could come in 2 hours. They were in hour house in less then 2 hours gave us 3 options for replacing the pump and completed the job before noon so we had time to run our errands. They did not charge extra for a weekend call and were very professional. Cleaned up after they finished everything and took time to explain everything they have done. Wonderful service!"

"I'm not fully moved into the home yet, but I will update when I am there permanently. The crew was very professional, worked diligently, cleaned up after every day of work (three day job--french drain expansion, two additional sump pumps installed, window drains into the sump pumps, pretty extensive job)."

"The team was very knowledgeable and helped explain my options. Gave me upfront pricing for each option so I could weigh those options before proceeding with a sump pump replacement. The parts were delivered and installed on the same visit. It helped keep my basement dry."

"They performed the work quickly and the guy was nice but the charge was 480 for a clearing a basement accessible drain. Got quotes from other for 150-350~ for clearing the same drain but wouldn’t come out as soon as DE plumbing pros. Seems very overpriced and wouldn’t use again unless I absolutely had to. Their customer service was good and theirs plumbers professional."

"The moisture entering our home through foundation walls and permeating the interior environment was a concern for the health of our home and our family. The French drain, sump pump and EZ Breathe Ventilation system recommended and installed by Worthington made an immediate and significant improvement to the air quality in our home and the long-term stabilization of our structure. The team was highly professional in consultation and performance. We couldn't be more satisfied or relieved!"

"Waterproofing One did a great job. Steve came Thursday night to estimate the job and had it completed the next day. I could not ask for better service. Drywall needed to be patched, carpeting needed to be removed, and installation of foundation drains out front of our home were installed by two great workers. Work is guaranteed."

FAQs for sump pump or interior foundation drains installation projects in Wilmington, DE

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.
