How many calls does a one-truck plumbing company actually miss?

We've all done it. It's 7pm, you're elbow-deep in a water heater that was supposed to be a forty-five minute job, the phone buzzes in your pocket, and you make the call every tradesman makes: whoever that is, they can leave a voicemail.

They didn't leave a voicemail.

Nobody leaves a voicemail. About 28% of calls to small service businesses go unanswered, and the majority of those callers don't try again — they dial the next plumber on the list. That water heater you finished? Nice work. It may have quietly cost you a $900 job.

I'm going to walk through the actual numbers — how many calls a small shop misses in a week, what an average missed call is worth by trade, and what the fixes cost, from "hire a service" to "let software answer." Fair warning: I sell one of the fixes. I'll show you the math for the ones I don't sell, too.

The weekly math

Say a one-truck plumbing outfit takes 60 calls a week. At a 28% miss rate, that's about 17 calls that ring out, hit voicemail, or get bounced to a machine. Not all of those are jobs — some are wrong numbers, some are people just checking a price. Call it half are real leads: 8-ish real missed opportunities a week.

Close rate on an inbound call for an established local plumber runs somewhere in the 30-40% range if someone actually picks up and books it. So of those 8 missed calls, maybe 3 would've become jobs.

Average plumbing job value varies a lot by what kind of work you do — drain cleaning is cheap, a water heater replacement or a slab leak is not — but $300-$600 is a reasonable blended number for a residential shop. Call it $450.

3 jobs a week × $450 = roughly $1,350 a week, or about $5,800 a month, in jobs that rang your phone and then called somebody else.

That number moves around a lot by shop — this is deliberately rough math, and your real numbers might be a third of this or three times it. The ROI calculator on our plumbing page lets you plug in your own call volume, close rate, and job value instead of trusting my averages.

What the fixes cost

Do nothing. Free, and you keep losing whatever the math above says you're losing. This is what most one-truck shops are doing today, not because it's a good option but because nobody made the number visible.

Hire a full-time person to answer phones. Real cost is salary plus payroll tax plus the fact that one person can't cover nights, weekends, sick days, or the toilet break during your busiest hour. For a shop this size, this is usually the wrong tool — you're not big enough to keep someone busy 40 hours a week just answering calls.

A human answering service. Companies like AnswerForce or Smith.ai charge somewhere between $140 and $390 a month, often metered per minute or per call, with overage fees once you're past your plan. This works, but the pricing punishes you exactly when you need it most — the week of a cold snap or a string of burst pipes is the week your bill spikes too.

An AI receptionist. This is the category we're in, and I'm obviously not neutral here, so take the pitch with the grain of salt it deserves. The honest version: it answers every call at a flat rate, doesn't get overwhelmed by a busy week, and books directly into your calendar instead of just taking a message. It also isn't a human, and if that's a dealbreaker for your customers, it's not the right fix — but for most emergency home-service calls, "someone picked up and got my job on the books" beats "nobody picked up" every time, regardless of who or what answered.

The part where I tell you to check for yourself

I'm not going to ask you to trust the math above or my description of what Dialkeep does. Call the number on the plumbing page right now, describe a burst pipe, and see what happens. If it fumbles, you've lost ninety seconds. If it doesn't, you've got real information instead of a blog post's word for it.

That's the whole pitch, really: don't believe us, dial.
