Remember, your local Culligan expert serving Modesto offers a complete line of proven technologies for every application while other companies are quick to offer unproven solutions like descaler-gadgets or “magic beads”.

Don't wonder what's in your water - your Modesto Culligan Man® can tell you! The Culligan Man offers a free in home water analysis just by filling out the form above or by calling us at (209) 208-5940.

Testing of your water by a licensed local water expert is the key to determining if you have a water problem, how to solve your problem and what equipment and service you need to protect your family and home.


My home's water was cloudy and had a bad taste. I took Culligan up on their free water analysis offer. The test showed my home's water was suffering from nitrates and arsenic. Lucky for me, they recommended a whole house water filtration system that was very affordable and would remove the harmful chemicals. My friends and family will tell you that I was so pleased that I recommended Culligan to everyone and that they're now customers because of my positive experience.
