"The company was able to come out to look at our sinking garage within a week of initial contact. Reo confessed that he had never seen a garage laid without footings, and he wasn't sure how much it would cost to add them. I had another company come look and give me an estimate and called Reo back. Reo said he was confident he could do the job if needed, but if the other company had done it before, he would recommend using their service instead of his. While ultimately I did not hire this company, I appreciated their honesty and professionalism, and would not hesitate to call them for basement work or other work more in the scope of what they do."

"Great company to work with from start to finish. Not only did the crew come in time each day, they came early! They did great work and were the best value hands down. They were almost half the cost of the other guys who quoted our job. They added new concrete footers,new posts and reinforced the joists in my old basement beefier lifting it a bit. Great job all the way! I will be calling them soon to add a new sump pump at our new house now."

"Dave was amazing! Being a single female I had no clue what to expect or have done and Dave walked me through the whole process. From framing, to the last piece of trim, Dave oversaw every step of the process and always made sure I was well informed of every decision. It was a great experience through and through."

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

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.
