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

Great experience. Quality product and employees. Joel was great on the sales side and Josh was super during the installation.

Excellent products & service!! Service personnel always friendly, knowledgeable & helpful & on time!!

Everything about this is super convenient and easy. The water tastes so much better than the water available to us.

Even though we haven't had/needed service for quite a while, when we did we got quick dependable service. Both the softner and the rust filter are working well.

They were able to take me on as a customer after being dropped by my other water delivery service. Friendly, responsive, and professional staff. So glad I found them.
