7 jobs trades businesses are handing to AI, and what it costs

You are under a sink with both hands wet when the phone rings. By the time you can answer it, the caller has hung up and phoned the next plumber on the list. That call, not the wrench, is where AI has landed in the trades.

Construction is one of the slowest Canadian industries to take AI up. Statistics Canada found that 9.2% of construction businesses used AI to produce goods or deliver services in the year to mid-2026, against 19.2% of businesses overall. Only agriculture and wholesale trade were lower.

The surveys disagree because they ask different people. Statistics Canada samples businesses across the country. ServiceTitan and Housecall Pro sell software to contractors, and surveyed contractors directly; Housecall Pro's sample was 248 of its own customers and contacts in the US. Housecall Pro says its own results should be read directionally, not as a population estimate.

What they agree on is where the AI goes. Housecall Pro's summary puts it plainly: pros are not using AI to get better at their trade, but to hand off "the scheduling, estimating, invoicing, and follow-up." We picked the seven jobs below because each one shows up in that survey or in named, reported examples. They run roughly from most common to least.

1. Answering the phone when nobody can

Verdict: the clearest payoff, because a missed call is a lost job.

Phone calls are still how most work arrives. In ServiceTitan's survey of more than 1,000 residential specialty contractors, reported by ACHR News, 60% of first contacts came by phone and 13% through online booking. An AI receptionist answers in a natural voice, asks what is wrong, and sends the details or books the job.

Housecall Pro found 40% of its AI users say AI helps them respond faster and lose fewer leads. One of its customers, Chris O. of NW Moss Removal, said only 15–20% of callers used to leave a voicemail. With the AI answering, 60–70% now leave a name, address and the service they need. That comes from the vendor's own report, so treat it as a best case.

Cost: Jobber lists its AI Receptionist at US$29 a month as an add-on to its field service plans, with Jobber's own plans starting at US$21 a month, billed annually. The page does not say what call volume that covers, so ask before you sign.

2. Turning photos and notes into quotes

Verdict: the biggest time saver, as long as a person checks the numbers.

Estimates, quoting and pricing are the second most common use among Housecall Pro's AI users, at 51%, just behind customer messages. The job is familiar: a tech sees the problem, then someone spends the evening typing it up.

The roughly 20 plumbers at Oak Creek Plumbing & Remodeling, near Milwaukee, carry tablets with ChatGPT, CNN reported. They photograph a broken water heater or type their observations, and it drafts proposals and invoices. "It's definitely been worth the investment," company president Dan Callies told CNN.

The catch is that the model does not know your prices, your supplier's costs or what you found behind the wall. It writes a clean quote either way. Feed it your own price list and have someone read every line before it is sent.

Cost: a general chatbot subscription, or the quoting tools already inside field service software. The real cost is the minutes spent checking.

3. Following up with customers

Verdict: low risk, easy to start, and the one most shops skip.

Customer communication and follow-up was the most common use in Housecall Pro's survey, at 52%. That covers appointment reminders, "we're on our way" texts, thank-you notes and the maintenance reminder a year later.

It matters because the jobs trades want most are repeat ones. In the ServiceTitan survey, 53% of contractors named customer retention as a top goal for 2026. A drafted follow-up that a person approves costs almost nothing and rarely goes wrong.

Cost: usually included in the field service software you already pay for. Check your plan before you buy anything separate.

4. Invoices and the rest of the paperwork

Verdict: where the hours come back.

More than one in four of Housecall Pro's AI users said they save six or more hours of admin a week. Oak Creek's plumbers produce invoices from the same photos and notes they use for quotes.

Six hours a week is most of a working day. For an owner-operator who does the books at night, that is the difference between invoicing on Friday and invoicing next month.

The AI is not doing the trade. It is doing the evening after the trade.

Cost: part of most field service platforms; a separate chatbot works too, but then someone has to copy the result into the books.

5. Looking things up on site

Verdict: useful, but the manual still wins an argument.

At Gulfshore Air Conditioning & Heating in Niceville, Florida, technicians use AI to diagnose problems and pull up technical information in seconds. According to CNN, that used to mean sifting through as many as five 60-page manuals.

This is also where a wrong answer costs the most. A chatbot can be confidently wrong about a model number or a clearance, and it does not carry your licence. Use it to find the right page faster, then read the page.

Cost: a chatbot subscription, or the AI assistant in your field service software.

6. Booking and dispatching without a person

Verdict: possible now, but only after the first five are working.

At Gulfshore, CNN reported, no human is involved from the moment a customer requests service to the moment a technician arrives. The AI takes the request, books it and sends the tech.

That is the far end of item 1, and it only works when the booking rules are simple and written down: which jobs, which areas, how long each takes. A shop that still keeps the schedule in the owner's head has nothing for the software to follow yet.

Cost: usually a higher tier of field service software or a dedicated dispatch product. Get a written quote.

7. Marketing campaigns

Verdict: the biggest reported number, and the hardest to trust.

Gulfshore told CNN it saw a US$370,000 increase in revenue 30 days after upgrading to an AI marketing feature that automates campaigns. It also reported US$150 more revenue per average ticket after AI tools freed up technicians' admin time.

Those are one company's figures, over a short period, in a busy Florida market. They say AI marketing can work. They do not say it will work for a four-person electrical contractor in Ontario in February.

Cost: varies widely. Start with the marketing tools already in your software, and measure before and after.

What holds shops back

The reasons contractors give for not using AI are reasonable. In the ServiceTitan survey, 53% said operational complexity, or not knowing where to start, was their biggest hesitation. 43% said they don't trust AI outputs, 32% worried about data security and privacy, and 29% named cost.

The trust worry is fair. Every use above goes wrong in a predictable way: a quote with the wrong price, an answer from the wrong manual, a caller who gets stuck. The fix in each case is the same: a person checks before anything reaches a customer, at least for the first few months.

Privacy is the other one. An AI receptionist collects names, home addresses and often recordings of calls, and quoting tools collect photos of the inside of people's homes. Under PIPEDA, you must tell customers what you collect and why, and protect it. Ask any vendor where the data is stored, for how long, and whether it trains their models.

And some shops should not bother. If you answer every call, write two quotes a week and do the books in an hour, there is nothing here worth paying for yet.

The seven jobs side by side

Where to start

1. Count your missed calls. Pull two weeks of call logs from your phone provider and see how many went unanswered, and when. If the number is small, skip item 1.
2. Check what you already pay for. Most field service software now includes AI features for messages, quotes and invoices. Turn one on before buying anything new.
3. Pick one job and check its work for a month. Read every AI-drafted quote or message before it goes out, and keep going only if it is saving real time.
