Reviews for Culligan Water of O'Fallon

Overall rating: 5⁄ 5

  • Bob Eulberg

    Great service, will definitely use again. Matt provided great service in helping us with the water quality on our private well water. He was determined to find and fix the cause of our water issues. He discussed some expensive options to replace our softener system, but thought that overkill and recommended starting with a simpler, less expensive solution (pre-sediment filter). I appreciated the honesty. During the process he explained a lot about water quality and how it's impacted by our well, softener, and reverse osmosis system. That's paid dividends in letting me better maintain the systems since.

  • Nick Autotech

    The people at Culligan take great care of our water needs. If by chance we run out, they are quick to get us an extra bottle or two.

  • Shamrock Concrete

    Our water is delivered on time every month and with friendly service. Also the water is fantastic!

  • Debbie Ferguson

    Great company. Everyone is very professional and friendly. The products are top notch and have greatly improved our water. We lease our softener and have never had a problem with it.

  • Paul Tapia
