"We had foundation repair done recently in bitter cold weather. Joe Autry, Larry Robinson, Dante' Gladden and William Lawrence worked continuously to get the job done before the snowstorm hit. These guys were unbelievable; they had to hand dig our property to get the job done. We are so impressed by their workmanship, work ethics and dedication to ensuring the job was done correctly."

"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."

"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "

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.
