Family-owned. Phoenix-based. Built on honest pricing and clean water.
The Phoenix valley has some of the hardest water in the United States. Anyone who's lived here for more than a few months has seen what it does — scale on every faucet, crusty white spots on glass, dishes that come out of the dishwasher cloudy, water heaters that fail years before they should. The water is technically safe to drink, but it's hard on homes, hard on appliances, and hard on the people living with it.
We started Louis Water Co with a simple goal: bring honest, professionally installed water treatment to homeowners across the entire valley — at a fair price, without the high-pressure sales tactics that have unfortunately defined this industry for decades.
Most water treatment companies require an in-home consultation that's really a two-hour sales pitch with "today only" pricing. We don't operate that way. We give you a quote based on your home and water concerns — over the phone or through our form. No theatrical process, no pressure.
The price we quote is the price you pay. We back this with our written Pricing Guarantee on every job.
Every system we carry is sized and configured for Phoenix's specific water — high TDS, very high hardness, varying chlorine, and on the well side, iron and sulfur. We've installed enough systems across the valley to know what actually holds up here and what doesn't.
We're based in Gilbert and serve the entire Phoenix valley. When you call us, you reach the actual people doing the work. When something needs follow-up, we come back — because we live here too.
We install across the entire Phoenix valley: East Valley (Gilbert, Mesa, Chandler, Tempe, Queen Creek, Apache Junction, Fountain Hills), Central (Phoenix, Scottsdale, Paradise Valley, Ahwatukee), West Valley (Peoria, Glendale, Surprise, Goodyear, Avondale, Buckeye, Litchfield Park, Tolleson, Sun City, Laveen), North Valley (Anthem, New River, Desert Hills, Cave Creek, Carefree), and Northwest (Waddell, Wittmann).
Locally owned — based in Gilbert, AZ. We're not a franchise or branch of a national chain. When you call us, you reach the people doing the work.
The entire Phoenix valley — East Valley, West Valley, Central, North Valley, and Northwest. If you're in the metro and aren't sure if we cover your zip, just call.
We're a newer company built by people who know the water treatment industry and wanted to do it better — no high-pressure sales, no surprise pricing, straight talk about what your home needs.
No. Our own trained techs do every installation.
Yes. We pull from publicly available municipal water quality reports and cross-reference with real-world install data. If something has changed since we updated a page, we'll tell you — and we always test at install before we leave.
