What the answers show
- AI assistants named 25 different plumbers in Denver, but only 3 came up on three or more engines.
- Answers here are unstable. Asking the same assistant the same question three times often produced a different list (stability 13/100), so a single check of your visibility can mislead. Perplexity varied most, at 0/100.
- Applewood Plumbing Heating & Electric and High 5 Plumbing were named most often, in 5 of 12 answers each.
- Of the directory and review sites, angi.com was cited most, in 5 of 12 answers. That is where the assistants went to check plumbers in Denver.

Is your business in these answers?
Leolens asks ChatGPT, Gemini, Perplexity and Claude the questions your customers ask, every month, and shows whether they name you and whether what they say about you is true.
Plans start at $799 per month for one location. For plumbing businesses we write your question set with you first, and nothing is charged until it exists.
Why some plumbers show up and others don’t
Assistants recommend what they can find and cross-check. What tends to help:
- Show emergency availability where assistants look for it: 24/7 hours on your Google Business Profile, the same hours on your website, and a phone number a person answers.
- Keep your business name, address and phone number identical on Google, Yelp, Angi, the BBB and HomeAdvisor.
- Publish a page for each job type (water heaters, drain clearing, slab leaks, repiping) and each city you cover, with your license number and what a visit includes.
- Collect reviews that name the job and the neighborhood. "Replaced our water heater in Denver" gives an assistant more to work with than five stars alone.

How we collected this
In October 2026 we asked ChatGPT (gpt-5.6-terra), Gemini (gemini-3.8-flash), Perplexity (perplexity/sonar) and Claude (claude-sonnet-5) the question Who is the best plumber in Denver, CO?
3 times each, through each provider’s API with web search turned on, as a new conversation with no account, history or location. A separate model listed the businesses each answer named; we checked every name against the answer’s own text and merged different spellings of the same business. Sources are the sites the engines linked to.
The apps use your location and history, so what you see there can differ. Nothing on this page is a rating or review by Leolens, and no business paid to appear. For how this market compares with the rest, see the October 2026 study.
