"A Dry Pro team came out today and installed a "crawlspace drainage system". Jonathan the team leader, came to me first thing this morning with full specifications and scaled drawings of the project. We went over everything that was to be done and verified all the locations around the house. Edwin and Taylor the other team members got to work right away. Jonathan took beginning, unprocessed and completed photos and videos. The team cleaned up the worksite beautifully. While Taylor and Edwin finished loading the truck I went over the job and viewed the photos and videos Jonathan had taken. I am very satisfied with the job and the hard work Taylor, Jonathan and Edwin did. If you have a moisture I highly recommend Dry Pro."

"They did a great job! My roof looks great! Reliable and kept me well informed about everything. They kept cost in mind and cleaned up nicely after themselves. Serge even came out late to tarp the roof until it could get repaired so that I didnâ t have any further damage to the house waiting for the roof. They were very nice to work with. Great people. I canâ t say enough good things about them!"

"Superior Plumbing was excellent to work with. From the start they stayed in communication, showed up when stated, applied shoe covers when entering our home, were neat while performing the service and fixed the problem very quickly. They were so clean I couldn't tell they were here. Thank you Superior Plumbing!"

FAQs for sump pump or interior foundation drains installation projects in Cornelius, NC

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.
