"We built our house 20 years ago. We discovered the master bathtub was leaking to our family room. Glenn tried to just reseal the drain but found our builder used the wrong materials and didn't properly configure it. Glenn apologized for having to cut the ceiling to get to the pipe that needed to be replaced but finished the repair quickly and cleaned up everything. I would definitely recommend Glenn at Hosack Plumbing to anyone needing plumbing help."

"I hired permajack due to a recommendation from my concrete guy. My foundation was sinking all around the perimeter. They offered a permanent solution and delivered. This was not a fun purchase but it was very necessary. Foundation repair is expensive, so Im pleased that these guys were on time, experienced and pleasant to work with. They cleaned up after themselves and the President of the company called me to follow up to make sure everything was delivered as promised. I highly recommend them. They were professional, respectful of my property and didnâ t waste my time. This can be rare in construction these days. Good well done!"

"The company had a person in the area and sent him to give a a diagnosis of the problem with our sump pump and an estimate of the cost to fix it. This was 2 days ahead of the scheduled appointment. However we got a cheaper estimate from a company we have done business with before."

"Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

FAQs for sump pump or interior foundation drains installation projects in O Fallon, MO

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.
