"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)."

"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."

"They came and inspected the sump pump. They recommended for it to be replaced. I was okay with it so they replaced it. They completed within half an hour. We then discussed the bill. They agreed to take off $50 because they have an Angie's List coupon that offers $50 off. There was also a coupon for $250 off a system installation for Angie's List members. I told them of this and they said it would only apply for HVAC units and I said to them that they are more than HVAC company, they provide more services than HVAC. They did not specify that its only for HVAC. The technician agreed and said that they're going to have to change that within our website. This was extremely misleading and felt like a bait and switch."

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"The required fix required that outside trenching be done and B-Dry does not do this type of work. The representative was very knowledgeable about the problem and apologized for not being able to solve the issue. Very much appreciated his honesty."

FAQs for sump pump or interior foundation drains installation projects in Knoxville, 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.
