"A simple request turned into a mammoth project involving the installation of piers to shore up my foundation, but I'm glad for the work being done. Everyone involved did a good job, and Trevor Atwell was great as my contact."

"Perfect job! First time they came out they determined the problem was in the gasline encased in stonework. Recommended getting a stonemason to chip away the rock, expose the line. Lined up the stonemason and phoned Jamison to make the appointment. Owner of company told me he would personally come out at the time of the stonemason to make sure no more stone than necessary removed. He did so. After rock removed, one of Jamison's plumbers came out, replaced the gasline (obstructed w/years of corrosion) and replace the ignition switch, reassembled the burner and ignited the pit. This company has first class workers and know what they are doing! Highly recommend for complicated jobs, such as this one! Thanks!

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