Ask anyone selling phone software and you’ll hear the same number: plumbers miss roughly 62% of their inbound calls. It comes from industry research on plumbing call handling — not our customer data — and it sounds too bad to be true, right up until you think about where you were the last five times your phone rang. Under a sink. Driving. Elbow-deep in a sewage backup. The honest question isn’t whether you miss calls. It’s what those calls are worth — and you can work that out with your own numbers in about two minutes using our missed-call calculator. Here’s the math it runs, laid out in the open so you can argue with every step.
Start with the calls you actually get
A two-truck shop doing steady work typically sees somewhere between 100 and 200 inbound calls a month once you count everything — new customers, repeat customers, suppliers, confirmations, the odd robocall. Say 150 to keep the math easy. Not all of that is money: in most shops, roughly half to two-thirds of inbound calls are genuine job inquiries — a person with a problem, deciding who to hire. Call it 90 real inquiries a month.
How many do you miss?
The industry figure is about 62% unanswered. Take it with some salt — it’s an average, and averages include the shop that never picks up. So be generous with yourself: say you’re disciplined, someone tries to grab the phone, and you still miss 40–50%. That’s not a character flaw; it’s physics. You can’t solder and talk. And the timing works against you, because about 68% of plumbing emergencies happen after hours — exactly when nobody is even pretending to answer.
A missed call isn’t automatically a lost job — but it’s close
This is where most missed-call math cheats, so let’s not. Some missed callers leave a voicemail and wait. Some call back. A routine “quote me a bathroom rough-in” caller might try you twice. But emergency callers don’t wait for anyone: industry research says 85% of emergency callers hire the first plumber who answers. The person standing in two inches of water is not working through a list of voicemails — they hire whoever picks up, and they never think about you again. Blend the patient callers with the gone-in-sixty-seconds ones and a fair assumption is that about half of your missed inquiries never reach you again. From 56 missed calls, that’s roughly 28 lost conversations a month.
Now apply your close rate and your ticket
You don’t win every call you answer, so don’t count every lost conversation as a lost job either. A typical shop books somewhere between 40% and 60% of genuine inquiries it actually talks to. Take 50%. And put a real number on the average ticket: for most service plumbing it lands between $300 and $450, pulled upward every time a water heater or a drain replacement is on the other end of the line. Take $350 to stay conservative.
What the math leaves out (it undercounts)
That $59K is one year of first tickets, and a plumbing customer is not a one-time transaction. The homeowner whose 2 a.m. call you caught becomes the water heater in three years, the bathroom reno in five, and the neighbour they recommend next month. The caller who couldn’t reach you leaves no review, sends no referrals, and — worse — hands all of that to the competitor who picked up. The math also skips the callback tax: the hour you spend every evening returning voicemails from people who, statistically, have already hired someone else.
There’s also a category the 62% figure doesn’t even try to measure: the soft miss. You answered — driving, one hand on the wheel, no calendar in front of you — and said “let me call you back this afternoon.” On paper that’s an answered call. To the caller it’s the same as voicemail: no price, no time, no commitment. A chunk of those quietly dial the next shop, and no phone report will ever show it. And the misses don’t spread themselves out politely: they cluster exactly when demand spikes — the January cold snap, the spring thaw — which means you miss the most calls in precisely the weeks each call is worth the most.
What to actually do about it
Answer more calls yourself. Free, but you’re the bottleneck — every answered call costs wrench time, and it does nothing for the 68% of emergencies that come after hours.
Hire office help. Solves weekday daytime properly. Runs $2,800–$4,500 a month all-in, and the desk is dark at 9 p.m. We break down that trade-off in receptionist vs answering service vs AI front office.
Use an answering service. A human picks up 24/7 for $235–$939 a month in practice — but takes a message. You still make the callback, quote the job, and book it. See the full comparison on our plumbing answering service page.
Put an AI front office on the line. CrewMate answers every forwarded call 24/7, gives the caller a ballpark from your own price book, books the job into a real opening on your calendar, and texts you what happened — $99–$349 CAD a month flat.
Whatever you choose, start by knowing your number. Run the calculator with honest inputs. If the result is a rounding error, congratulations — you’re rare. If it looks like a truck payment, the phone is the cheapest problem in your business to fix.
