FROZEN PIPES: How to Prevent Them This Winter—and What Insurance Actually Covers
Winter in Southeast Wisconsin can be unforgiving. When temperatures plunge, frozen pipes become one of the most common and costly cold-weather claims. The good news: with a few practical steps, most freeze-ups are preventable. Below is a clear, homeowner-friendly guide to help you avoid burst pipes, understand what your policy covers, and know exactly what to do if the worst happens.
Why Pipes Freeze (and Where It Happens Most)
When air temperatures drop below 20°F for several hours, standing water inside pipes can freeze and expand. That expansion creates extreme pressure that can split copper, PEX, or PVC. High-risk areas include:
-Unheated spaces: garages, crawl spaces, basements near foundation walls, and unfinished utility rooms.
-Exterior walls and attics with inadequate insulation.
-Kitchen and bathroom sinks set against outside walls.
-Outdoor hose bibs, sprinkler lines, and detached buildings.
Quick Prevention Checklist You Can Do Today
-Insulate exposed lines: Wrap foam pipe insulation around accessible hot and cold lines in basements, crawl spaces, and garages. Pay special attention to elbows and tees.
-Seal drafts: Use spray foam or caulk around pipe penetrations, sill plates, and rim joists to keep frigid air out.
-Open cabinet doors on cold nights: Let warm household air circulate around sinks, especially in kitchens and baths located on exterior walls.
-Let a small drip run: A slow cold-water drip keeps water moving, which reduces freeze risk and relieves pressure.
-Maintain steady heat: Keep thermostats at a consistent setting, ideally not below 60°F, even when away. Consider smart thermostats and low-temperature alerts.
-Disconnect and winterize outdoor lines: Remove hoses, use insulated faucet covers, and shut off and drain exterior spigots if your home has interior shutoff valves.
-Know your main shutoff valve: Ensure every adult in the household can locate and operate it quickly.
What Your Home Insurance Typically Covers
Every policy is different, but here are general guidelines commonly seen in Wisconsin homeowners policies. For specific guidance, talk with Bill Sweetman Agency so we can review your exact coverage and carrier rules.
-Sudden and accidental water damage from a burst pipe is often covered. This may include tearing out and replacing materials to access the broken pipe and repairing resulting water damage to covered parts of the home.
-The cost to repair the actual broken pipe may or may not be covered, depending on the carrier and endorsement language.
-Damage from long-term leaks or from lack of maintenance is usually excluded.
-Mold and mildew coverage varies widely. Some policies include limited remediation; others require an endorsement for higher limits.
-Frozen pipe coverage in vacant or unheated homes can be restricted. If a home is unoccupied or under renovation, special steps or a different policy form may be required.
How to Thaw a Frozen Pipe Safely
If you open a faucet and only a trickle comes out, you may have a frozen section.
-Shut off the water at the main if you suspect a burst.
-Open nearby faucets to allow pressure release.
-Warm the area gradually with a hair dryer, portable space heater at a safe distance, or heat tape approved for pipes. Move from the faucet end back toward the frozen spot.
-Never use an open flame or propane torch. This is a major fire hazard and can damage pipes and materials.
-Call a licensed plumber if you cannot locate the freeze or reach it safely.
What To Do If a Pipe Bursts
-Shut off the main water supply immediately.
-Document the damage with photos and short videos of the affected areas and your mitigation steps.
-Start mitigation right away: mop up standing water, run fans and dehumidifiers, and move undamaged items to a dry area.
-Call Bill Sweetman Agency so we can help review your coverage, open a claim with your carrier, and advise you on next steps.
-Keep receipts for emergency repairs, temporary heat, and drying equipment.
Pro Tips That Reduce Claim Severity
-Smart leak detectors and automatic shutoff valves can catch problems while you sleep or travel.
-Heat cable for known trouble spots (installed to manufacturer instructions) provides extra protection.
-Upgrade insulation in rim joists, foundation walls, and around pipe chases during any remodel or weatherization project.
-Service your heating system annually so a mid-January furnace failure does not cascade into a freeze event.
When To Consider Endorsements or Policy Changes
If you have a finished basement, older plumbing, radiant heat, or a history of freeze-ups, it may be wise to review:
Water backup and sump overflow endorsements
-Higher limits for mold remediation
-Equipment breakdown endorsements for certain systems
-Vacancy or renovation coverage if applicable
A short annual review often uncovers small, cost-effective tweaks that can save thousands during a claim.
