Typical Florida installed cost for whole-house water filter: $1,000–$5,000 — a curated 2026 planning range, not a bid. The most accurate figure for your home comes from a verified local pro (free, below).
Iron staining in Florida water — reddish-brown stains on fixtures, laundry, and sinks — comes from iron in the water, common in wells, and an iron filter or treatment removes it.
Plan it — not an emergency.
Common causes:
• Dissolved iron in well water
• Iron bacteria in the well
• No filtration targeting iron
• High iron content in the local groundwater
• Bleaching stains repeatedly instead of treating the iron
• A softener alone expected to fully handle heavy iron
• No water test to measure the iron level
• Water-treatment equipment itself isn't a licensed trade, but the plumbing or electrical tie-ins can be — verify a licensed plumber or electrician for those connections
Why does my water leave reddish-brown stains?
That's iron, common in Florida well water. Dissolved iron oxidizes and stains fixtures, laundry, and sinks reddish-brown, and iron bacteria can make it worse. A water test measures how much iron you have, which determines the treatment — an iron filter or specialized system, sometimes alongside a softener. Bleaching only treats the symptom.
Can a water softener remove iron?
A softener handles small amounts of dissolved iron, but heavier iron or iron bacteria usually needs a dedicated iron filter or oxidizing system. Expecting a softener alone to fix a heavy iron problem leads to disappointment and a fouled softener. A water test tells you the iron level so the right treatment is chosen.
Whole-house water filter: $1,000–$5,000 (typical ~$2,500)
Sediment, carbon, or specialty filtration; water quality and system size drive it.
Curated Florida 2026 estimate — installed cost for a typical FL single-family home, not a bid.
This trade spans two license realities in Florida. Drilling, constructing, or repairing a water well is licensed by the regional Water Management District. Installing water-treatment equipment — softeners, filters, reverse-osmosis — is generally not a state-licensed trade on its own, though the plumbing and electrical connections can require a licensed plumber or electrician. Verify the credential for the specific work.
Different scopes here carry different permit and license needs — ask who holds which before work starts.
