Reviews for Culligan Water of DeKalb
Overall rating: 4.8/5

I've used Culligan on multiple occasions. They installed our water softener, moved the water softener to our new house, installed reverse osmosis and delivers salt to us. They are always easy to get a hold of and I've never had any issues. Been a customer for about 3 years now.

Always great service, and extremely accommodating.

Great people and great service.

We appreciate the service of delivering to us at our office. Its one less thing to have to GO buy. With the exception of the last fellow who made deliveries- he wasn't very friendly at all... Michael has always been great and Drew is very nice too. Rose always answers any questions we have and we are glad to have a local service providing our supplies.

What Clients Say
We used a different company that was bought out by Culligan. However, living in MI and using Culligan for years it was a no brainer to stick with them. Always excellent customer service and all the technicians have been wonderful to deal with. We are on a Artesian spring well so the only treatment we require is a neutralizer for PH. We drink straight out of the tap and it’s crystal clear, odorless, and delicious. I can’t say the same for any other well system we have owned. God has blessed us with amazing water!
