Is Northern Virginia water actually a problem?

Honest answer: it's moderately hard. Not the worst in the country, but hard enough to scale up water heaters, spot your glassware, and stiffen laundry over time. On top of hardness, a lot of homes here taste chlorine, and older neighborhoods can pick up sediment from aging mains. None of that means your water is unsafe. It means your water can be better, and your equipment can last longer.

The only way to know what's in your water is to test it. That's why we start there, and why the test is free right now.

What about PFAS?

PFAS, the so-called forever chemicals, are a real topic in the DC region, and worth taking seriously without the scare tactics. Start with facts: your water utility publishes a water quality report every year with its actual PFAS results. Look yours up before you buy anything. If the numbers bother you, or you just want a margin of safety for drinking and cooking water, a reverse osmosis system at the kitchen sink is the most proven fix. Certain certified carbon filters reduce PFAS too. We'll match the fix to your test results and your utility's report, not to a sales quota.

Softener, whole-home filter, or reverse osmosis: which one do you need?

A water softener fixes hardness. Scale in the water heater, spots on dishes, crusty faucet aerators, dry skin after showers. It treats every tap in the house, but it doesn't change taste much.

A whole-home filter fixes taste, smell, chlorine, and sediment at every tap. It's the "my water tastes like a pool" fix. It doesn't soften hard water.

Reverse osmosis is the deep clean for one tap, usually the kitchen. It handles the stuff you actually drink: taste, lead, PFAS, and more. It's the highest level of treatment, applied where it counts.

Plenty of homes pair two of these: a softener or whole-home filter for the house, RO for the drinking water. Your test tells us which combination earns its keep. Your home, your call. We educate, we don't pressure.

What does water treatment cost in Northern Virginia?

Whole-home water filtration starts at $1,600 installed. These are our actual prices for the DC metro, July 2026. Not national averages, not teaser rates. Softener and reverse osmosis systems get a flat quote after your free test, because the right size depends on what's in your water and how much of it your household uses. You approve the price before we start, and it includes the permit when one's required.

Virginia daytime diagnostic is $75, waived with repair. Free neighborhood estimates. Free second opinions with a written competitor quote. And through September 30, 2026, the water quality test itself is free!

Want to know what's in your water?

The test is free through September 30, 2026, and you keep the results either way.

Water treatment FAQs

How much does whole-home water filtration cost?

From $1,600 installed in Northern Virginia. Softeners and reverse osmosis systems are quoted flat after a water test, which is free through September 30, 2026. You approve the price before we start.

Is Northern Virginia tap water safe to drink?

It meets federal standards, and your utility publishes a water quality report every year that shows exactly what's in it. Treatment here is mostly about hardness, taste, chlorine, and extra protection at the kitchen tap, not about unsafe water.

Do I need a water softener in Northern Virginia?

Maybe. Our water is moderately hard, which is enough to shorten water heater life and scale up fixtures in many homes. The free test gives you your actual hardness number, and then it's your call.

What removes PFAS from drinking water?

Reverse osmosis at the tap is the most proven fix, and certain certified carbon filters reduce PFAS too. Check your utility's water quality report first so you know whether you have a PFAS number worth acting on.

Is the water quality test really free?

Yes, through September 30, 2026. No purchase required, no obligation. You get your numbers either way.
