"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."

"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!"

"It went very, very well. They showed up on time and stayed late to get our basement put back into tip top shape as quickly as possible. It took approximately six weeks to complete the full job. They would have finished sooner if I didn't have to have this special shower surround, me and my bright ideas which went on back order as we entered into pandemic mode! But I loved it all when they finished. I have two sump pumps and they are my go-to team ANYTIME I have problems. Again, they show up quickly and do great work!"

"The cracked pipe ended up being between the first and second floor where drain pipes from the upstairs bathrooms came together in a Y-joint. The house is 45 years old and these old plastic pipes eventually crack from flexing, etc. which is exactly what had happened. Fred had to cut 10 inch wide strips in the drywall in the kitchen and bathrooms walls and ceilings to get at the area to replace the leak. He added some rubber sleeves to the new Y-joints to allow for some flexing of the house so this would not happen in the future. When all was done, the repair was $2300 and I had to hire a drywall contractor for another $500 to fix the drywall, but Fred was upfront about the price, the extent of the damage that would have to be done for the repair, and the need to fix the drywall after he left. While it really stinks to have to cough up almost $3K to for a leaking pipe, that's the cost of owning a home build in the 1970's with cheap materials and I was very impressed with the work done by Fred and his same day responsiveness. At least the leak was noticed right away so we did not have any water or mold damage to deal with."

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.
