Water Filtration and Treatment Services in San Mateo
Fourteen services, one rule: we measure first. Pick the problem you're seeing, or let a reading decide for you.
One Crew for Every Tap in the House
San Mateo water is soft, chloraminated and generally clean when it leaves the utility. The problems start inside the house: a chemical taste at the kitchen sink, rust from an old galvanized run, scale in a tankless heater, a coastside well that has never been treated.
These are the services that solve those problems. Each page explains what the visit looks like, what we fit, and when you probably don't need it.

Grouped the way houses use water: whole-home, drinking water, problem-specific, and upkeep.

Whole-House Water Filtration
We size the tank to your flow rate and plumbing, then put it in where the supply enters the property. Expect better-tasting water at the kitchen and showers without the pool smell, with media that runs a long stretch between changes.

Water Softener Installation
Some houses on private wells or blended reservoir supply do run hard. We measure first, then size the resin tank and brine setup to the grains your place actually has.

Reverse Osmosis Systems
We fit RO with a catalytic carbon pre-stage so the membrane is shielded from chloramine. Readings before and after show the TDS drop right at your tap.

Under-Sink Drinking Water Filters
No storage tank, no drain line, and cartridges you can swap yourself. A sensible choice for condos, rentals, and houses that only need better water at one tap.

Carbon Filtration Systems
We choose between standard and catalytic carbon based on a chloramine reading. Systems range from a single kitchen cartridge to a full tank on the main line.

UV Water Purification
We pair every UV unit with the pre-filtration it needs, since cloudy or iron-laden water shields microbes from the light. You get a properly sized chamber, a fresh lamp, and a clear service routine.

Salt-Free Water Conditioners
A conditioner suits houses with mild hardness or a tankless water heater that needs protecting. We take a reading first, because on soft San Mateo water you may not need one at all.

Well Water Filtration & Treatment
Every well is different, so we take readings before recommending a single piece of equipment. Then we fit a treatment train sized to your flow, from prefilter to UV lamp.

Sediment Filtration
We look at what's actually coming through, then fit the right screen or micron rating for it. Clear bowls and gauges make cartridge changes easy to time.
Open the details -
Iron & Sulfur Removal
Oxidizing filters turn dissolved iron and hydrogen sulfide into particles that can be trapped and backwashed away. Readings come first, so the media matches your water.
Open the details -
Scale Prevention & Water Heater Protection
San Mateo's supply is mostly soft, so many heaters need a periodic flush rather than a softener. Where readings run higher, a salt-free conditioner or cartridge protects the unit.
Open the details -
Commercial Water Filtration
Restaurants, cafes, salons, and offices each have different water demands. We take readings on site and set up cartridges and change schedules around your hours.
Open the details -
Water Testing & Analysis
Some answers come from a meter at your kitchen counter, while others need a certified lab. We tell you which is which, so treatment only goes in where a real reading calls for it.
Open the details -
Water Filter Repair & Maintenance
Most problems come down to a worn seal, a fouled cartridge, or a part at the end of its service life. We find which, fix it, and set a sensible upkeep schedule.

What Stays the Same on Every Job
Measured first
Chloramine, hardness, TDS and pH, read at your tap before any recommendation.
Priced on paper
A flat written figure for each option. No surprises on the invoice.
Looked after later
We log your cartridge and membrane dates and remind you when they're due.
Tell Us What You're Noticing
A taste, a stain, a slow shower, a well you've never tested. Describe it on the phone and we'll suggest the right first step, often just a reading.
