AI search for plumbers: what owners need to know
Part of our series on AI visibility by trade and city. The reference guide is the AI visibility directory by trade and city.
Nobody researches a plumber for fun. People look for one when a pipe has burst, a boiler has died or a bathroom needs redoing, and they want a reliable name fast. A growing number now skip the directory and ask an assistant, and ChatGPT, Gemini or Claude answers with two or three specific firms and a reason to trust each one.
For a plumbing business, that answer is the whole job: the caller rings down the names until someone picks up. This guide explains what AI search means for plumbers, what customers ask, how the assistants decide, and what our scans of six cities found, including the uncomfortable fact that the most-named name is often not a plumber at all.
More customers now ask ChatGPT, Gemini or Claude for a plumber before they open a directory, and the way those assistants choose which firms to name decides whether the emergency call is yours. It pays to understand why some plumbers stay invisible to AI and to check where you stand before the next cold snap.
What customers ask AI when the water is already on the floor
Plumbing questions are urgent and practical. Customers ask who can come today, who is trustworthy, who handles boilers, and who is fair on price. Each one ends with the assistant naming firms, and the caller acts on the first one that answers:
- “Who should I call for a burst pipe if I need an emergency plumber today?”
- “Can you recommend a reliable plumber near the station?”
- “Top five most trusted and highest-rated plumbers in the city”
- “Which plumbers specialise in boiler repairs and central heating problems?”
- “Plumbers offering affordable, good-value bathroom and kitchen repairs”
What AI actually says about plumbers: our scans
Our September 2026 plumber scans asked ChatGPT and Gemini six questions each, the kind someone types with water on the floor, in London, Dubai, New York, Los Angeles, Chicago and Miami: 72 answers in all, with every firm named and every website cited written down. The full readout, city by city, is on the plumbers directory; the short version is below.
Plumbing is the most concentrated of the seven trades in our six-city scans. The assistants named 116 different firms across the six cities, but the leading name in a city appeared in 42% of that city's answers on average, against a third in the other trades, and in New York and Chicago the leader was named in half the answers. The leaders were not always plumbers: in London the most-named name was a trade directory, in Dubai a services marketplace, and in New York and Miami the same national franchise. Only Los Angeles and Chicago had an independent local firm on top. ChatGPT and Gemini agreed on at least one firm in three of the six cities.
The sources behind the answers make the point sharper. The single most-cited website was that national franchise's own site, cited 26 times, nearly three times more than the next source. Then came the trade platforms, Checkatrade and Angi, the review directories Expertise.com and ConsumerAffairs, and New York City's consumer-affairs pages. No independent plumber's own website made the top six. For an owner the reading is direct: the assistants find plumbers through platforms and vetting bodies, and a complete, consistent, well-reviewed presence there is what turns a franchise recommendation into yours.
In our October 2026 Gemini study, Roto-Rooter's own site was the most-cited source for plumbing questions in the English-speaking cities, in 36% of answers, ahead of ConsumerAffairs (24%) and Angi (21%). Gemini named no plumber in 6% of those answers but in 32% of the French ones, and fewer than a quarter of the plumbers it named (23%) held on through three asks of one question.

See where you stand
Reading about AI search is useful; knowing your own place in it is what helps. A free Peekl check asks ChatGPT or Gemini, your pick, the questions your customers ask and shows whether it recommends you today, who it names instead, and how often. The full audit runs the same questions on all three assistants, Claude included.
