Freeze & burst pipes

What to do after a burst pipe. What the carrier pays for.

A frozen pipe that thaws and bursts — usually on the second night of a cold snap, usually in a ceiling cavity or exterior wall — is a documentation problem before it’s a money problem. The first 24–48 hours set the ceiling on every later argument, and the carrier’s playbook on these files is consistent: shutoff within minutes, prevent further water damage, document the pipe’s location and material for the adjuster, and rebut the “pre-existing wear” and “cold-weather maintenance” denials before they show up in the first letter. Below is the playbook we run on every freeze file: what to do (and what not to) in the first day, the five-step LightHouse process, a sample recovery band, and the carrier pushbacks we argue back. Reach out the moment the water’s stopped flowing — the earlier we’re on the file, the more coverage we can pull through.

The first 24–48 hours

What to do. What to avoid.

The first two days set the ceiling on every later argument. Half of this column is the work most policyholders never think to do; the other half is the work that quietly hands the carrier its strongest Freeze/Burst-Pipe denials — and they usually arrive in the same envelope.

Do

    Shutoff the main valve within minutes — and document the time.The single biggest move on a freeze file is closing the main and writing the time on a sticky note. The carrier will look for a documented shutoff record; no record, no coverage argument when the “failure to mitigate” letter arrives.
    Mop standing water and start air-movement / dehumidification BEFORE the carrier’s adjuster arrives.The 24–48-hour window after a burst is when secondary damage — mold, swelling subfloor, ruined insulation — attaches. Documented drying (psychrometric dry-log, dehumidifier readings, moisture-map before/after) is the rebuttal; improvised drying is the concession.
    Photograph the failed pipe section — material, location, and any visible wear.Copper, PEX, galvanized, PVC — material and location (interior wall, attic, crawlspace, hose bib, irrigation) tell the adjuster where the failure lives. Date-stamped photos of the failed section rebut the “pre-existing wear” denial before the carrier writes the letter.
    Pipe the plumber’s written source report to us the moment they finish.A licensed plumber’s independent report — material + cause + loss date — is the single best rebuttal to a “cold-weather maintenance” or “pre-existing wear” denial. We forward it into the claim file before the carrier’s first response.

Avoid

    Don’t cut out the failed pipe section before you photograph it and before the plumber ’s invoice is in.The failed section IS the evidence. Cut it out and the source report is just a plumber’s recollection — not a date-stamped exhibit. Photograph the joint, the corrosion pattern, and the burst mode; keep the cut-out in a bag for the adjuster.
    Don’t crank the heat back up and dry the house without documenting moisture first.Cranking heat drys the surface and lets hidden moisture migrate into the wall cavity. The carrier then argues the moisture was “pre-existing seepage.” Documented moisture-map readings before, during, and after drying rebut that framing.
    Don’t accept the flat mitigation line on the adjuster’s first estimate.Mitigation cost (extraction, dehumidifier rental, content pack-out, antimicrobial treatment) is recoverable under ALE and the policy’s “reasonable expense” clause — but only what’s receipted and date-stamped to the loss. We re-open the line with the IICRC dry-log and contractor scope.
    Don’t sign a blanket release from a mitigation contractor without us reading it first.Mitigation contractors sometimes push a blanket authorization that caps the recoverable line item at their own scope. Don’t sign — a licensed public adjuster needs to read it alongside your policy before anything goes to the carrier.

The LightHouse 5-step process

From the cold snap to a signed settlement.

Every freeze file is different — second-floor laundry, attic supply line, exterior hose bibb, irrigation manifold — but the structure of a strong claim is the same. Here’s what working with LightHouse on a freeze/burst-pipe loss looks like, start to finish.

  1. Step 01

    Emergency response + on-site scope

    Within 24 hours of engagement we coordinate mitigation, secure the structure, draw a moisture-map baseline, and start the date-stamped photo + dry-log. Freeze losses move fast — the 24–48-hour mitigation window after the cold snap sets the ceiling on every later argument, and mold risk attaches after that.

  2. Step 02

    Policy review + coverage mapping

    We read the policy end-to-end: dwelling, contents (RC vs. ACV), ALE, code-upgrade, “burst pipe” vs. “freeze” coverage language, Cold-Weather Maintenance / Neglect exclusions, debris removal, and “reasonable expense” mitigation coverage. The framework drives the claim, not the carrier’s first letter.

  3. Step 03

    Full loss documentation

    Plumber’s source report, line-item inventory, contractor scope, contents priced at current replacement cost (not ACV), moisture-mapping readings, the psychrometric dry-log, hidden moisture in wall cavities and subfloor, and code-upgrade line items carved out from cosmetic repair.

  4. Step 04

    Third-party estimate

    We commission an independent, licensed plumber’s source report AND an independent estimator’s Xactimate-style scope. Carriers litigate their own numbers; they negotiate harder against an independent source-and-scope pair, which moves the recovery up.

  5. Step 05

    Negotiation + settlement

    Filed, rebutted, re-opened, escalated as many times as it takes. You review and approve the final number — we don’t sign until you do.

Carrier pushbacks we argue back

The four denials we see most often on a freeze file.

The carrier’s playbook on a freeze/burst-pipe claim is consistent. Below are the four pushbacks we argue back most often — anchored on “pre-existing wear” plus “cold-weather maintenance” — and how our rebuttal frames the line item back open.

  • Carrier tactic

    “Pre-existing wear” — the pipe was already corroded / past its service life

    Our rebuttal

    Carriers love a “this was already worn” denial on copper and galvanized. We rebut with date-stamped pre-loss photos, the licensed plumber’s source report pegging the failure to the event date, and the pipe-spec / install date pulled from the permit record.

  • Carrier tactic

    “Cold-weather maintenance / neglect” — failed to maintain adequate heat / winterize

    Our rebuttal

    We rebut with thermostat / smart-sensor records, neighbor attestations, and NWS weather-history showing the cold snap was forecast and localized — plus the policy’s own “burst pipe” vs. “freeze” coverage distinction, which most policies treat as a covered peril, not a maintenance carve-out.

  • Carrier tactic

    “Slow seepage, not a sudden burst” — this was a long-term invisible leak

    Our rebuttal

    We rebut with a dated moisture-map log (taken before drying), the plumber’s source report tying the failure to a single event date, photos of the standing-water line and the failed pipe section, and home-water-bill records that rebut any “slow seep” theory.

  • Carrier tactic

    “Mitigation is homeowner responsibility” — deny dehumidifier / extraction / contractor line

    Our rebuttal

    ALE and the policy’s “reasonable expense” clause pay mitigation cost that demonstrably reduced the loss. We re-open the line with the receipts, the moisture-map before/after, the IICRC contractor’s scope, and the carrier’s own accepted emergency-mitigation precedent on similar freeze files.
