Reviews for Culligan of Merrillville
Overall rating: 4.9/5

Joe was extremely helpful when trying to determine which system would work best with our household needs. He responded to our questions and concerns in a timely manner and was very professional throughout the process. Joe demonstrated his extensive knowledge of the products during our in home consultation. I would definitely recommend Culligan of St John to anyone looking to enhance their at home water needs.

Very timely on the work they performed. The unit works great, definitely can tell a difference in feel of the water and a difference in taste of the food as well. Very well done culligan.

The salesman was very thorough in testing our water. He showed us the results as he went through each test. It was good to see how much iron was in the water. The installer Justin was on time. He explained the installation plan. Got right to it and finished in the estimated time. Everything was cleaned up and the old softener taken away. We were especially happy that the new softener started working right away. We will definitely recommend Culligan to everyone.

The service is fantastic! It's great to have water delivered right to your door. Very accommodating and so easy!

Jon and Chris were very easy to work with, professional & easy going, as well as knowledgeable!

What Clients Say
We recently purchased a new water softener and reverse osmosis from Culligan in St. John. We can’t recommend them enough. Joe was very thorough in explaining everything twice, once to my husband and another time to me because we had our kids with us. They had a little table for the kids to color and play at. Scheduling was a breeze and installation went extremely well. I love that when it’s time for a new filter they will sent you a notification, which is awesome that I don’t have to think about it.
