If you run a trades business — plumbing, heating, electrical, roofing, renovation — your phone is your cash register. And it rings at the worst times: when you’re under a sink, up a ladder, driving between jobs or finally sitting down for dinner. So calls get missed. Most owners shrug it off: “They’ll leave a message.” Many don’t.

Why callers don’t wait

Think about how people find a tradesperson today. Something breaks, they search “furnace repair near me”, and Google shows them a handful of businesses. They call the first one. If nobody answers, they don’t wait — they tap the next number on the list. By the time you call back an hour later, someone else may already be booked.

This is especially true for urgent jobs, which are often the most profitable: no heat in January, a burst pipe, a power problem. A homeowner with water on the floor isn’t leaving a voicemail and waiting patiently.

Work out your own number

You don’t need industry statistics — you can calculate your own cost in a few minutes:

  • Count your missed calls. Check your phone’s call log for a normal week. Count calls you didn’t answer and didn’t return within an hour. Ignore obvious spam.
  • Estimate your close rate. Of the enquiries you do answer, what share turn into paid work? If you don’t track it, 30–50% is a reasonable starting guess for many trades.
  • Know your average job value. What does a typical job bring in?
  • Multiply: missed calls per week × close rate × average job value × 52 ÷ 12 = lost revenue per month.

For example, a plumber who misses 5 calls a week, closes 40% of enquiries and averages $400 a job is looking at roughly 5 × 0.4 × $400 × 52 ÷ 12 ≈ $3,470 a month in work that may be going to competitors. Your numbers will differ — try them in our free missed-call cost calculator.

The hidden costs

The lost job is only the start. A customer who books with a competitor today may become their regular customer for years — every annual furnace service, every renovation, every referral to a neighbour. Missed calls also cost you reviews you would have earned and the momentum that comes with a busy schedule.

Ways to stop missing calls

1. Missed-call text-back

The simplest fix: when you miss a call, the caller automatically gets a text like “Sorry we missed you — this is Northside Plumbing. What can we help with? We’ll call you back shortly.” It tells them a real business is on it, keeps them from immediately calling someone else, and often gets you the job details in writing. It’s included in every Aethely plan, from $19/mo.

2. An AI receptionist

An AI receptionist goes further: it answers the call itself, says it’s an AI assistant for your business, asks what’s wrong and where, flags emergencies, books routine jobs into your calendar and texts you a summary. You can finish the job in front of you and call back the urgent ones first, already knowing what they need. We’ve written more about how AI receptionists work for plumbers and HVAC companies.

3. A live answering service

Human answering services take messages around the clock. They work, but are usually priced per minute or per call and can’t always answer detailed questions about your business.

4. Hiring office help

A part-time or full-time office person is great once you’re big enough to keep them busy — but it’s a big fixed cost, and it still doesn’t cover evenings and weekends.

Setting up missed-call text-back the right way

A text-back message is only as good as what it says. Keep it short, friendly and specific: your business name, an apology, a question that gets the job details, and a promise of when you’ll call back. For example: “Hi, it’s Northside Plumbing — sorry we missed your call, we’re on a job. What’s going on and what’s the address? We’ll call you back within the hour.”

  • Send it within a minute of the missed call — speed is the whole point.
  • Make sure replies come to a phone you actually check, and answer them.
  • Don’t send it to numbers that call you all day, like suppliers or your own team.
  • Keep a promise you can keep. If you can’t call back within an hour, say “this afternoon”.
  • Track how many missed calls turn into texts and booked jobs over a month.

Combined with a quick callback, text-back alone recovers a good share of calls that would otherwise be lost. An AI receptionist goes a step further for the calls that need an answer right now.

Make the most of the calls you do get

  • Call back within minutes, not hours, whenever you can.
  • Put your service area and hours on your Google profile and website so you get fewer calls you can’t take.
  • Use a quote form that asks the right questions, so web leads come with details.
  • Ask every happy customer for a Google review — more reviews mean more calls from people who already trust you.

The bottom line

Missed calls feel small in the moment — one call, one voicemail. Added up over a year, they can easily be one of the biggest leaks in a trades business. The fix doesn’t have to be expensive. Start by counting your missed calls for a week; the number usually makes the decision for you.
