A plumbing business runs two businesses at once. One is scheduled work — a water heater swap, a bathroom rough-in — that behaves like any other booked trade. The other is somebody standing in two inches of water at 7pm. They need completely different messaging, and the mistake is running one playbook across both.
The photo before the van
This is the highest-value message in the trade and almost nobody sends it. Before dispatching, ask for a photo of the problem and the shutoff.

Hi Dana — Ray at Vance. Before I send someone: can you snap a photo of where it's leaking and one of the shutoff under the sink? Helps me send the right van with the right parts.
here you go
That's a failed supply line, easy fix. Turn that valve clockwise until it stops and the water stops now. Tom can be there between 8 and 10 tomorrow, or tonight at emergency rate — your call.
morning is fine, thank you!!
iMessage carries that photo at full quality, which matters when you are trying to read a fitting or a model plate. An MMS version of the same photo is often genuinely unusable — it is the same fidelity argument as roofing hail damage, on a smaller invoice but many more jobs.
Stopping the water is free and buys you enormous goodwill
Telling someone where the shutoff is, before you have been paid anything, is the single cheapest trust purchase in this trade. They will remember it, and they will tell people. Put a saved shutoff-location message in your team's snippets.
Arrival windows are the whole complaint category
Almost every negative review in this trade is about waiting rather than workmanship. The customer took a day off, nobody came, and nobody said anything.
| When | Message | Why it matters |
|---|---|---|
| At booking | Window, technician name, what to clear | Sets the expectation you will be held to |
| Evening before | Confirm the window, one-tap reschedule | Catches the change while you can still fill the slot |
| On the way | Name, ETA, photo of the tech if you have one | Removes the stranger-at-the-door problem |
| Running late | Before the window closes, with a new time | The only message that prevents the review |
| Job done | What was fixed, photo, invoice by email | Turns the work into something they can show a partner |
The fourth row is the one businesses skip because it feels like admitting failure. It is the opposite: a late arrival you were warned about is an inconvenience, and a late arrival in silence is a betrayal. The wider arrival-window mechanics are in the home services playbook.
Approving work from the crawlspace
Plumbers routinely find a second problem once they are under the house. The homeowner is at work. You need a decision, and a phone call they do not answer costs you the job.

Dana — Tom's under the house. The main shutoff is corroded through; it'll fail within a year and it's $340 to replace while he's already down there. Photo attached. Want him to do it?
yes do it
Three rules for these: send the photo, name the actual number, and say what happens if they decline. Never present it as a scare — this trade already fights a reputation for invented problems, and a photo plus a real timeframe is how you separate yourself from that.
After-hours triage
If you advertise emergency service, someone has to answer at 11pm. If you do not, an auto-reply must be honest about it — with a real alternative rather than a promise you will not keep.
- Answering: reply within minutes, ask for the photo, tell them how to stop the water.
- Not answering: "We're closed until 7am. If water is actively running, shut off the main — usually where the line enters the house or by the meter. If you can't find it, call 555-0142 and we'll walk you through it."
- Never: silence, or "we value your message". What good out-of-hours replies look like.
The repeat business nobody sends
Plumbing has weak natural repeat frequency, which is exactly why the follow-up matters. Two messages, a year apart, cost nothing:
- Ninety minutes after the job: a review request, while the relief is fresh. Why the timing is the whole play.
- Twelve months on: water heater age, softener service, or a seasonal note about pipes and the first freeze. Not a sale — a useful reminder from someone who has been in their house.
Do not run cold lists in this trade
Homeowner lists bought by neighbourhood are the fastest way to get your line flagged and your number burned, and you need that number for the customers who actually called you. Message people who contacted you. Why numbers get flagged and what counts as consent.
What to measure
- Truck rolls avoided by a diagnostic photo — the fastest payback in this list.
- On-time arrival rate against your stated window.
- On-site approval rate, and how fast approvals come back.
- Reviews per completed job.
- Twelve-month reactivation rate from the annual message.
