"I forgot to do this review but am glad I did because I am two years out having waterproofing services by this company. The drain and sump pump recommended by Robert Ellis is absolutely worth it. I no longer am anxious about weather forecasts because of the work done. Robert evaluated my home, gave me options and soft recommendations then allowed me space to make the best long term decision. Completely satisfied and would recommend."

"Great experience. Tawn was excellent - he knew what he was doing, got the sump pump removed, cleaned out the sump, repaired a pipe, then installed a new pump. Very happy, will definitely call Tawn back for any future plumbing needs!"

"Kap from Joseph Plumbing and Drain was great. I requested a quote Saturday morning and they came out within a few hours. We scheduled the work for Friday and they arrived on time, were friendly and professional, and did excellent work installing my new main water shut-off valve. Highly recommend."

Customers say: True professional

"I contacted Fred by email first, as on his website, it says you can either call or email. But there was no response to my email for a couple of days, so I decided to call. Fred asked me to text him my address. He made an appointment to come to the house a couple of days later. He came on time, drilled a hole through the concrete block in the basement and installed a new faucet. He added a bleeder valve to the copper pipe and explained how I should bleed the pipe after turning off the inside valve before the cold winter months. Fred was pleasant and informative. He did a good job. It took about an hour and 15 minutes. To contact Fred, you might want to send him an email explaining the work needed, and include your phone number so he can call you back. Or send him a text that includes your address."

"Woke to realize that our sump pump failed during the night and water was quickly accumulating from the ongoing rain. Rema was the first to respond to my HomeAdvisor message. He was at our house with all of the required pieces and parts within the hour and had the sump pump replaced and most of the water drained within another hour. He was quick, courteous, professional and the cost for the repairs very reasonable. He was also helpful in making recommendations on restoration support needed. I highly recommend Rema."

FAQs for sump pump or interior foundation drains installation projects in Kensington, MD

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.
