Southwest Florida wells draw from groundwater that picks up minerals and gases on its way to your tap. That’s not a sign anything is broken, but it shows up as smells, stains, spotty glassware and short-lived fixtures. Treatment is how you live comfortably with a well.

Well Water Treatment System in Southwest Florida

What Your Well Water Is Telling You

What you notice	Usual cause
Rotten-egg smell in hot and cold water	Hydrogen sulfide gas in the well water
Rotten-egg smell in hot water only	A reaction inside the water heater, not the well
Orange or brown stains on sinks, tubs, walls or driveways	Iron
White crust on faucets and shower glass, soap that won’t lather	Hardness (calcium and magnesium)
Cloudy or gritty water	Sediment, sometimes a sign the pump needs attention
No sign at all	Bacteria and nitrate can’t be seen, smelled or tasted, which is why testing matters

Florida’s Department of Health puts it plainly: private well owners are responsible for the safety of their own water, and should have it tested for bacteria and nitrate every year. Bacteria and nitrate are tested by a certified lab or your county health department; our in-home test covers the everyday water chemistry, such as hardness and chlorine, that decides which treatment system fits.

Treatment Options We Install

Whole-home well water treatment packages ($4,561 to $11,656). These treat all the water entering the house. We offer them in several levels, and the right one depends on what your water test shows and how much water your household uses. Your plumber will explain why a level fits before you choose.

Whole-home reverse osmosis ($13,170 to $18,712). Reverse osmosis pushes water through a very fine membrane and removes far more of what’s dissolved in it than a standard filter. It’s the most thorough option, for wells with water that other treatment can’t bring where you want it.

Softeners and filters. If hardness or a single problem is all you’re dealing with, a water softener or one of our water filtration systems may be enough, and costs less than a full package.

How a Treatment Visit Works

We look at your system and test the water. Coming out is $0 (an $85 holiday fee applies on holidays and is waived when we do the work); the in-home water test is free.
We explain the results in plain words. You’ll hear what’s in the water, what it’s doing to your home, and which options fix it.
You choose, with prices in front of you. Nothing is installed until you approve.
We install and check the system. Your plumber shows you how it works and what upkeep it needs.

A treatment system can only do its job if water reaches it, so our plumbers also look at the well pump and pressure tank while they’re there. If the pump is struggling, see our well pump services.

Every installation carries our 1-year workmanship warranty, extended to two years for Nerd Pass members. Read how our pricing works for the full picture.

We install well water treatment across Collier, Lee and Charlotte counties, including Naples well homes and Lehigh Acres. Call (239) 215-3330 any time, day or night.

Well Water Treatment Questions

On today’s price book, whole-home well water treatment packages run from $4,561 to $11,656, and whole-home reverse osmosis from $13,170 to $18,712 (checked 11/04/2026). The right level depends on your water test.

If both hot and cold water smell, the hydrogen sulfide is in the well water, and a whole-home treatment system is the usual fix. If only the hot water smells, the problem is usually inside the water heater, and changing its anode rod often solves it.

Orange and brown stains are usually caused by iron in the water. Treatment that removes iron before the water reaches your fixtures and sprinklers stops new stains from forming.

Yes. State health officials advise a yearly lab test of a private well for bacteria and nitrate. Our free in-home test checks the everyday chemistry that tells us which treatment fits.

Not always. Reverse osmosis removes more of what’s dissolved in the water, but it costs more, and many wells are fully fixed by a treatment package or a softener. Your test results decide.

Yes, financing is available with approved credit. See our financing options or ask your plumber.
