Typical Florida installed cost for salt cell replacement: $500–$1,600 — a curated 2026 planning range, not a bid. The most accurate figure for your home comes from a verified local pro (free, below). In Pinellas County, pool-adjacent permit activity over the last 90 days was in the 50+ band among records we track — public-record aggregates, not a national guess.
When a salt system stops making chlorine, the pool loses its sanitizer — the cause is usually a scaled or worn-out cell, or a salt level the system can't work with, before it's the control board.
Handle it soon — these get more expensive with time.
Common causes:
• A cell scaled up with calcium, insulating the plates so they can't generate chlorine — the most common cause
• A cell simply worn out, since the plates have a limited service life
• Salt level too low or too high for the system to operate
• A control board, flow sensor, or wiring fault stopping the cell from running
• A full new system sold when a cleaning or a replacement cell would restore it
• No check of salt level and cell condition before condemning the control board
• For the equipment and electrical work, no state license number is a red flag
• No explanation of how to keep the cell from scaling up again
Why did my salt cell stop making chlorine?
Usually scale on the plates or a cell at the end of its life. Inspecting and cleaning the cell, and confirming the salt level is in range, comes before replacing the control board — a pricier and less common failure.
How long does a salt cell last?
Salt cells are wear items with a limited service life, and hard water and skipped cleanings shorten it. Keeping it free of scale is the single biggest thing that extends it — so a cell that died young often points to a maintenance gap.
Salt cell replacement: $500–$1,600 (typical ~$900)
Replacement cell plus labor; cleaning is tried first, and control-board faults are separate.

Curated Florida 2026 estimate — installed cost for a typical FL single-family home, not a bid.
Florida licenses this trade at the STATE level (DBPR / CILB (CPC)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.
Work like this often requires a county permit — a legitimate pro pulls it, not you.
