The Most Recommended Plumbers in Raleigh — Measured on ChatGPT
When someone in Raleigh needs a plumber today, the question increasingly goes to ChatGPT before it goes anywhere else. So we measured what it says — 4 checks in August 2026, using 4 different question styles, against 56 local companies.
Every name below earned its place by being recommended — nobody paid and nobody applied. 16 companies were named this edition, and William Parrish Plumbing alone was named in all 4 checks.
One step down: CK's Plumbing & Backflow, LLC, Optimal Plumbing Solutions, Inc. and Out The Door Plumbing and 2 more, named in 3 of 4 checks. 2 more companies came up less often and are listed below.
Why no "#1"? Because it wouldn't hold. Run the same questions again and the top name often changes, while the count of checks that named a company stays put — so the count is what we publish. A single mention isn't enough to make the list.
For scale: of the 26 metros in this edition, Raleigh's cohort of 56 plumbers was the 26th largest.
Only 16 of 56
plumbers we verified around Raleigh were ever recommended — 29% of the cohort. ChatGPT's picks:
Rankings are measured and cannot be purchased — sponsored blocks are labeled advertising and sit outside the ranked list.
Ask ChatGPT the same question twice and the answer can change. So we do not crown a number one. We publish how many of the 4 checks named each company. Companies named in more checks are the ones ChatGPT keeps coming back to. Companies named in only one check are not listed: a single mention does not repeat reliably.

August 2026 edition · 4 real-question checks · Measured, never sold: no company can pay its way onto this list. Naming frequency alone decides which group a company lands in.
The exact questions we asked
We asked these word-for-word, then recorded which companies came back in the answers:
- “Who is the best plumber in Raleigh, North Carolina?”
- “I have a plumbing emergency in Raleigh, North Carolina. Which plumber should I call?”
- “What is the most recommended plumbing company in Raleigh, North Carolina?”
- “Who should I hire to replace a water heater in Raleigh, North Carolina?”
Inside the Raleigh data
- The listed companies average 4.9 stars on Google, with 9,245 reviews between them.
- Raleigh's 29% named rate runs above this edition's overall average of 28%.
- However the question was phrased, William Parrish Plumbing kept coming back — 4 of 4 checks.
- 8 of the 16 companies ChatGPT named came up in more than one check. The other 2 surfaced once and aren't listed — a single mention doesn't hold up on a re-ask.

Raleigh questions, answered
How many Raleigh plumbers does ChatGPT actually recommend?
In August 2026 we counted 16 Raleigh companies that ChatGPT actually named, from a verified cohort of 56. That's a 29% hit rate; the other 40 never appeared.
Which plumber does ChatGPT recommend most in Raleigh?
William Parrish Plumbing was the most consistent answer of the August 2026 edition, surfacing in every one of the 4 checks.
Why isn't there a number one on this list?
Because a number one wouldn't hold. Ask ChatGPT the same question again and the top name often changes, while the number of checks that named a company stays about the same. So we publish the count: companies named in the same number of the 4 checks are grouped together and listed alphabetically, because nothing in the measurement separates them.
How was the Raleigh list generated?
The same questions real homeowners type — including "Who is the best plumber in Raleigh, North Carolina?" and "I have a plumbing emergency in Raleigh, North Carolina. Which plumber should I call?" — and we recorded every company named in the answers. The full set of phrasings is listed on this page.
Can a company pay to be on the Raleigh list?
No. This list is measured, never sold — a company appears only if ChatGPT actually recommended it, in more than one check, when we asked. Money cannot buy a place on this list. Paid messages on this page are labeled "Sponsored" and sit outside the measured list.
Why isn't my company on the Raleigh list?
Because ChatGPT didn't mention it more than once across the August 2026 checks. That's a visibility gap, not a quality verdict — and since each quarterly edition starts from zero, it's a fixable one.
New to Raleigh? These plumbers are just getting started.
Everything above this line was measured. The list on this page comes from asking AI assistants real questions and counting who they named — no one can buy their way onto it.
This section is different, and we want to be plain about it. The businesses below are brand new. They have not been measured, they have no rank and no score, and they are not part of the list above. They are here because they asked to be, we checked that they are real, and a business that opened last month has no way to show up in a ranking built on history. Nobody paid for a spot here — it is free, and it is not an endorsement.
