What's your water telling you?

Pick the closest match. Each one is a sign of hard water, and a softener fixes all four.

  • Spots on every glass

    Hard-water minerals dry as white spots on glassware, dishes and shower doors. A softener removes them.

    See your options
  • Crusty faucets and showerheads

    Scale clogs aerators and showerheads and shortens their life. Softening stops the buildup at the source.

    Schedule a water test
  • Dry skin and stiff laundry

    Hard water keeps soap from lathering, so skin feels dry and laundry feels stiff. Soft water fixes both.

    See your options
  • Water heater dying early

    Scale builds inside the tank, cuts efficiency and shortens its life. Softening protects it.

Your options

Three ways to tackle hard water, and we'll help you pick

Every home's water is different. Your tech walks you through the real options for your water after a test, not a sales pitch.

Water softener (salt)

The most thorough fix for hard water.

  • Removes hardness minerals entirely: no spots, no scale
  • Sized 1, 1.5 or 2 cu ft to your hardness and usage
  • Brine tank set up and salt delivery handled by us

From $3,167 installed, sized to your hardness and usage

Salt-free conditioner

Scale control without salt, septic-friendly.

  • Halo H2 Zero Ultimate or Navien saltless
  • No salt to buy, haul or discharge
  • Best for moderate hardness and septic systems

From $3,651 installed (H2 Zero Ultimate)

Synchrony financing

Financing available. Qualifying projects can be financed through Synchrony. Ask about it when you request an estimate.

Why sizing matters

A softener is only as good as its sizing

Too small and it regenerates constantly and wears out. Too big and you waste salt and water. Most Sonoma County water is moderately hard, typically 5.5 to 12 grains per gallon depending on the source, so we measure yours before we size anything.

  • A 1 cu ft system fits many couples
  • Larger households often need 1.5 to 2 cu ft
  • Your household, your water use and your measured hardness decide it

The details, if you're comparing

Softener or salt-free: the honest breakdown

Same facts, side by side. Find the column that sounds like your house.

Water softener

Best for very hard water.

Ion exchange removes hardness minerals entirely. The most thorough fix.

  • Removes hardness: no more spotting, scale or dry skin
  • Sized to you: 1, 1.5 or 2 cu ft for your hardness and usage
  • Protects appliances: fixtures and appliances last longer
  • Low maintenance: we deliver salt and service on a schedule

Regeneration uses some water and salt, so right-sizing matters. On septic, or want to skip salt? A conditioner may fit better. Your water test decides.

Salt-free conditioner

Best for moderate hardness and no-salt homes.

Halo H2 Zero Ultimate and Navien saltless change how scale forms instead of removing minerals.

  • No salt: nothing to haul, nothing to refill
  • Septic-friendly: zero salt discharge
  • Low waste: no backwash water down the drain
  • Keeps minerals: conditions without softening

On very hard water a true softener still wins. We tell you honestly which side of the line your water falls on.

Chlorine taste too? Whole-house carbon systems (Halo 5, H2 Zero, Big Blue) clean up chlorine taste and odor at every tap and pair well with a softener. See Halo whole-house systems, or read how hard water affects your plumbing.

Water softener questions, answered straight

How much does a water softener cost installed?

Salt softeners start at $3,167 installed, sized to your hardness and usage, and the Halo Hybrid 2-in-1 is $5,365 installed. Your exact price depends on the size and your plumbing's layout, and you get a fixed price before any work begins.

What size water softener do I need?

It comes down to the people in your home, your water use and your measured hardness. That's why we test first. A 1 cu ft system fits many couples; larger households often need 1.5 to 2 cu ft.

Softener or salt-free conditioner: which do I need?

A softener removes hardness entirely, which is best for heavy spotting and very hard water. A salt-free conditioner controls scale without removing minerals, which is best for septic systems or moderate hardness. Your water test decides. See our water filtration overview for the full picture.

How hard is the water in Sonoma County?

Most of the county runs on moderately hard water, typically 5.5 to 12 grains per gallon depending on the source, and Santa Rosa averages around 5.5 to 6. Even moderate hardness builds scale over months and years.

Will a softener protect my water heater?

Yes. Scale builds inside the tank, cuts efficiency and shortens its life. Softening stops that buildup at the source, protecting your water heater, fixtures and appliances.

Do you deliver salt?

Yes. We set up the brine tank and handle salt delivery and refills on a schedule, along with annual inspections and regeneration tuning.

Do you repair softeners you didn't install?

Yes. We repair all major brands, refill salt, fix salt bridging and constant regeneration, and replace systems that have aged out.

Is the water test free?

We test your water on-site at no charge with any service call.
