Pre-freeze plumbing calls: Book the work before it bursts
The burst pipe is the expensive way to meet a customer
Every winter, a plumber meets a few hundred new customers at the worst moment of their year: Water coming through a ceiling at 6 AM. The job is real, but the homeowner is paying for it twice, once to you and once to the restoration company.
The damage is large and common. State Farm reports more than 20,000 frozen-pipe and winter water claims from January 2024 through June 2025, with over $628 million paid and an average claim payment above $30,000. The Insurance Information Institute, using ISO data, puts water damage and freezing claims at about one in 60 insured homes each year. How the desk handles the burst-pipe call itself is covered in our plumbing emergency triage guide. This post is about the weeks before it.
Most of the homes that will call you on freeze night are already in your CRM. They had a frozen line two winters ago, or a crawl space a tech flagged, or a hose bib you replaced. Nobody calls them in October.
Who belongs on the freeze list
Pull the list from job history, not from a marketing segment. You want households with a known risk that a short visit reduces.
Profile | Where to find it in your records | What to offer |
|---|---|---|
Past freeze or burst-pipe calls | Job codes and notes from prior winters | Inspect the repaired run, insulate the neighbors |
Older homes with crawl spaces or exterior-wall plumbing | Tech notes, home age, past repair locations | Pipe insulation, heat cable, sealing drafts |
Vacation and second homes | Billing address differs from service address | Drain-down, shut-off walkthrough, return check |
Irrigation backflow and outdoor faucets | Past backflow tests and hose bib repairs | Backflow winterization, frost-free hose bibs |
Plumbing in a garage or unheated addition | Install and repair notes | Insulation, relocation quote |
Depending on size, a shop might find a few hundred names or a few thousand. Rank them by risk, with past freeze calls and empty homes first.
Time it to the forecast, not the calendar
Water freezes at 32 degrees, but a pipe inside a house is partly protected. University of Illinois research found that uninsulated pipes in an unheated attic began to freeze when the outdoor temperature dropped just below 20 degrees, which is why many freeze guides call 20 degrees the temperature alert threshold. Pipes exposed to drafts can freeze above it.
That gives you two waves. The first runs two to three weeks before your area's usual first hard freeze, when booking is easy and techs have room. The second fires the day a 10-day forecast shows a night near 20 degrees, aimed at everyone who did not book. The second wave carries more urgency and leaves less time to work with.
What the call says
The call has four parts: Why you are calling this household, one fact, one offer, and a dated slot. A good opening sounds like this: We replaced a frozen line in your crawl space two winters ago, and the first hard freeze is coming. We can insulate the rest of that run this week. Thursday morning or Friday afternoon?
Then ask the question that pays off even when they decline: Do you know where your main water shut-off is? State Farm tells homeowners to find the main valve before winter and close it if a pipe bursts. Many callers do not know. Walk them through the usual spots, which are where the line enters the house, the garage or utility closet, and the curb box, or offer to show them during the visit. A customer who can close the valve in two minutes has a small leak instead of a flooded floor.
Add the basics the insurer also lists: Disconnect garden hoses, keep the house heated to at least 55 degrees, and let a faucet drip on the coldest nights.
Why the list never gets called
Nobody owns it. The list lives in the CRM, the CSRs are busy with inbound in October, and by the time the forecast turns, the phones are full of burst-pipe calls and the list is moot. Outbound loses to inbound every time they compete for the same person.
Run the math on your own numbers. As one illustration, a list of 2,000 at-risk customers, reached at 40%, booking at 10%, is 80 winterization visits in a shoulder month, plus several hundred households that now know where their shut-off is.
Running it without starving the inbound line
The fix is to stop asking the same CSRs to do both. An AI agent such as Revin can call and text the freeze list in both waves, book the visits into ServiceTitan during the conversation, and walk callers to their shut-off, while your CSRs keep the inbound line. On freeze night the same agent answers every call at once and transfers the true emergencies to your on-call team with the details attached. Build the list this week, and set the second-wave trigger before the first cold front arrives.
When should I winterize my plumbing?
Before the first hard freeze in your area, not after it. Pipes in attics, crawl spaces, garages, and exterior walls are the first to freeze, and outdoor faucets and irrigation backflow devices need to be drained before overnight lows drop well below freezing. In most cold climates that means October or early November. Booking early also matters because plumbers fill up fast once the first freeze warning is issued.
At what temperature do pipes freeze in a house?
Water freezes at 32 degrees, but pipes inside a home are partly protected by the building. University of Illinois research found that uninsulated pipes in an unheated attic started to freeze when the outdoor temperature fell below about 20 degrees. Pipes exposed to drafts through cracks, or pipes in exterior walls and crawl spaces, can freeze at warmer temperatures, especially in wind. Treat a forecast near 20 degrees as the alarm.
Where is my main water shut-off valve?
It is usually where the water line enters the house. In homes with a basement, look on the front foundation wall. In slab homes, check the garage, a utility closet, or near the water heater. In crawl-space homes it may be under the house. Many homes also have a valve at the curb or meter box. Find it, make sure it turns, and show everyone in the house before winter.
Should I turn off my water when away in winter?
For a trip of more than a few days in freezing weather, shutting off the main valve and opening the faucets to drain the lines is one of the safest steps. Keep the home heated as well. State Farm advises keeping the house at no less than 55 degrees. Vacation and second homes that sit empty for weeks benefit from a full drain-down done by a plumber before the season.
Does homeowners insurance cover frozen pipes?
Many homeowners policies cover sudden water damage from a burst pipe, but coverage can depend on whether the owner took reasonable steps such as keeping the home heated. The claims are large. State Farm reports that its average frozen-pipe claim payment from 2024 through June 2025 exceeded $30,000. Prevention work done in the fall costs far less than the damage, and it avoids the deductible entirely.
