"The company sent a very professional manager to supervise the work. It took almost two days of horizontal boring in our yard and under our homes slab foundation. The horizontal boring equipment and crew added a large expense to the total bill but was the only to get under the slab to the correct spot. The crew installed heavy duty PVC pipe with a liner containing heavy duty commercial grade hose. If anything leaks in the future, a new hose can be slipped in to replace the bad one at a minimal cost. After the repair work was completed, the landscaping was restored to new. Overall a very professional repair job, well worth the extra cost."

"SMK plumbing did a great job for me with a whole house water re-plumbing & main water line from the street. The team was efficient, professional, and polite. Job was started and completed in one day. They even moved the whole house shut off and pressure valve to a very easy to get to location."

"Steve preformed his job with expertise and professionalism. I shopped three different foundation repair companies before choosing American. All three sale representatives were nice. All three offered a different price. I recommend American Foundation to everyone."

"Jacob W. did an amazing job when he came out and inspected my cabin's foundation. He was on time, professional, and friendly. The best part was that he gave me the great news that there were no foundation issues to be concerned about and that everything looked good."

"Jeff told me the foundation settling was very minor for a house built in the 1970's.  No water problems in basement.  He did recommend I have the gutters replaced, with 6" gutters, and to make sure water is draining away from house.  Also, he asked me to contact him if the foundation settled more in the future.  He did not do any work other than give me a free evaluation.  Jeff was very professional and honest. I will definitely use his company if I have anymore foundation or drainage issues.

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

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.
