Holmes Water Treatment Co

I purchased a Water Softener and Filter from Holmes in November of 2022 and I couldn’t be happier. Grant was a great technician and would highly recommend him and his craftsmanship!

My softener wasn't working, after looking at it i notice the cam gear had broke. Called Holmes and sent them a pic and 2 mins later they told me to bring in it. I drove down and Cindy went to work and about 10 mins later i was all fixed up....cost 5.50. Thanks for the awesome service

Moved to lake St. Louis are and couldn’t believe the calcium and hardness of the water. Called Holmes, got w whole house filter and softener and every day I’m glad we did. Sales/install guy was great, honest, was here when he said and gone when he said. It would be first thing I’d get in new home that needed it! Totally recommend to anyone!

We hired Holmes to install a water softener system in our home. Grant was the technician they sent to our home for consultation and installation. He was professional, friendly, and smart. The builders of our home took some interesting liberties with the plumbing (most likely in an effort to save on construction costs) that made the install a bit tricky, but Grant was able to come up with a solution to place the softener where we wanted it to be placed in our basement with as little re-working of our existing pipe as possible. Regarding cost, Holmes' pricing compared to their competitors is amazing! I really appreciate a company that passes down some of their wholesale price savings to the consumer and that's exactly what Holmes does. Thank you, Holmes!

They are the best!! Customer service is great! Very friendly and helpful. If they are in our area they will just stop by to make sure everything is good. The aeration treatment system and water softener did they installed in her house worked perfectly.

Fair prices, outstanding service. Friendly and knowledgeable staff. Bob, Bobby and Robert are great. We have wonderful, clean soft water as well as RO water and little to no maintenance system. They really stand behind their Products and workmanship

So 25 years ago I bought a water softener for the ultra hard water here in O'Fallon, MO. The guy at the hardware store said in O'Fallon water softerners don't last 5 years because the water is so hard. Well, Holmes was my choice back then and we finally, 25 years later, replaced ours with another Holmes. Quick install, no interest payments like 25 years ago. They are simply the best in the entire area. I priced Culligan and they were a good 1000 dollars more for a lesser unit. If you want a family owned business that does you right, Holmes it is.

Mr Holmes Jr came out and assessed my situation, arrived on time, quoted me a great price to get a water softener installed in my home, and even offered me a 5% discount for my military affiliation

Bob was sincerely the most kind, knowledgeable and helpful contractor I’ve ever used. Cannot recommend them enough!

Great support on phone, returning soft water unit to service. Imagine, good service from a real human being! Much appreciated!

Robert was great in explaining and checking out our new water softener system great personality!!!
