Florida's Rare but Devastating Freeze Events
Florida freezes maybe once every 3–5 years, but when it happens, pipes burst across the state. A single burst pipe can release 250 gallons of water daily, causing $10,000+ in water damage. Here's how to prevent it.
Why Pipes Burst
Water expands roughly 9% when it freezes. If ice forms inside a closed pipe section, pressure builds until the pipe ruptures. Older copper and galvanized steel pipes are especially vulnerable.
High-risk areas:
- Exposed pipes under the home (crawlspaces, garages)
- Exterior water lines and outdoor faucets
- Attic supply lines with poor insulation
- Pipes near air conditioning return vents
Prevention Strategies
1. Insulate Exposed Pipes (DIY)
- Wrap pipes with foam pipe insulation (any hardware store, $1–2 per foot)
- Secure with duct tape
- Works for pipes in crawlspaces and attics
2. Drip Interior Faucets
- Open a slow drip (pencil-width stream) on indoor faucets during freezing nights
- Moving water freezes more slowly than stagnant water
- Costs pennies on your water bill but saves thousands
3. Open Cabinet Doors
- Under kitchen and bathroom sinks, open cabinet doors to allow warm house air to reach pipes
- Especially important for exterior-wall sinks
4. Close Off Outdoor Lines
- Before December 1, shut off exterior water valves
- Open the outdoor faucet to release pressure and drain remaining water
5. Keep Garage Doors Closed
- Unheated garages drop below freezing. Closed doors retain more heat
6. Leave Heat On
- Never turn off your AC thermostat completely during freezes
- Set it to 68°F minimum
- Works faster than opening cabinets; energy cost is minimal vs. damage
What To Do If Pipes Freeze (But Don't Burst)
Signs of a frozen pipe:
- No water from a faucet
- Visible frost on exposed pipes
- Unusual sounds from plumbing
Do NOT:
- Use a blowtorch or open flame (fire hazard)
- Pour boiling water on pipes (thermal shock causes cracking)
Do:
- Apply a heating pad or hairdryer to the frozen section
- Wrap the pipe with hot towels
- Call a licensed plumber if you can't locate the blockage
If a Pipe Bursts
- Shut off the main water valve (locate it before freeze season)
- Call a licensed plumber immediately — burst pipes require same-day repair
- Begin water extraction — Use towels and a wet-dry vacuum
- Document damage — Photos for insurance
- Call your insurance company — Most policies cover burst pipes under "sudden and accidental" damage
Plumbing Upgrades for Freeze Resistance
Copper vs. PEX tubing:
- Copper — More common in older Florida homes; freezes readily
- PEX (plastic) — Newer standard; slightly more freeze-resistant and expands without rupturing
- CPVC (plastic) — Best freeze resistance; common in modern builds
If you're renovating or adding lines, ask your plumber for PEX or CPVC.
Seasonal Checklist
October–November (Before Cold Season):
- Shut off and drain outdoor faucets
- Insulate any exposed exterior pipes
- Locate your main water shut-off valve
- Test the shut-off valve (it should turn smoothly)
December–February (During Cold):
- Monitor weather; activate drip faucets if freezes are forecast
- Inspect pipes in unheated areas
- Keep your thermostat at 68°F minimum during freezes
March (After Cold Passes):
- Reopen outdoor water lines
- Inspect pipes for slow leaks (sign of minor cracking)
- Replace any burst pipe sections found
How HALOFIX Can Help
If you need emergency pipe repairs or winterization:
- HALOFIX connects you with licensed master plumbers
- 24/7 emergency service available
- Prices are frozen during declared emergencies under Florida law
- All contractors are DBPR-verified and insured
An ounce of prevention (foam insulation costs $20) beats a pound of cure (water damage repair costs $10,000).
