Costa Mesa Water Pros tests, designs, and installs filtration and softening for homes across Costa Mesa, Newport Beach, Irvine, and Fountain Valley, and you know the price before any work begins.
Costa Mesa sits on hard Orange County municipal water, and every home reacts to it a little differently. Here is the full range we install and service, from a single kitchen filter to a whole-home treatment train.

After enough years working on Orange County water, you learn that most homeowners do not need the biggest system on the truck. They need the right one, quoted honestly.
No guesswork and no pressure. We start by finding out what is in your water, then handle the rest.
From Eastside and Mesa Verde to Newport Beach, Irvine, and Fountain Valley, we cover the corridor along I-405, SR-55, and SR-73 with the same testing, pricing, and crew.
Do not see your street? If your water comes off the same Orange County supply, we most likely cover you.

Costa Mesa Water Pros is a local water-treatment company built on one habit: test first, recommend second. We have spent our time on Orange County water learning which systems hold up and which ones just cost more.
We bring that straight talk to every Costa Mesa home we visit, quote a flat rate before any work starts, and stand behind the install for as long as you own it.
