Jerry Gaston made a service call to our home. He was on time, friendly, professional, and informative. I appreciate all of the above.

Our recent move to Texas left us with water we were not used to. It was hard, very chlorinated (more than our pool) and not safe to drink. One week after closing on our home we called Culligan to install a whole home water softener, and it has been wonderful.

Our recent move to Texas left us with water we were not used to. It was hard, very chlorinated (more than our pool) and not safe to drink. One week after closing on our home we called Culligan to install a whole home water softener, and it has been wonderful. Our water is now safe to drink, and I am able to keep the glass shower clean! We could not be happier with our Culligan system.

We had our new RO, Water softner and filteration system installed today.
Vlad called ahead, was on time and very curtious.
Both installers did a great job.
