The Most Recommended Chimney Sweeps in Denver — Measured on ChatGPT
This Denver edition started from 43 verified local chimney sweeps. We then asked ChatGPT — 4 different ways, 4 checks in August 2026 — and wrote down every company it recommended.
58% — that's the share of Denver's chimney sweeps ChatGPT actually recommends (25 of 43). The most consistent of them: CrownUp Pros, named in all 4 checks.
Chimney Sweeps of America and Clean Obsession Chimney Service LLC came next, named in 3 of 4 checks.
We don't crown a winner. ChatGPT gives a slightly different answer each time you ask, so the honest number is how many of the 4 checks named a company — not what place it came in. One mention out of 4 doesn't get published.
Among the 12 metros in the August 2026 run, Denver ranks 4th by cohort size, with 43 chimney sweeps benchmarked.
Only 25 of 43
Denver-area chimney sweeps we benchmarked ever get recommended by ChatGPT — that's just 58%. These are the companies it names:
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.

Measured August 2026 · 4 homeowner-style questions · This list is measured, never sold — no company can pay onto it. Groups are set by how many checks named each company; inside a group the order is alphabetical, because the measurement doesn't separate them.
What we asked ChatGPT
Every check used one of these real homeowner questions, and every company ChatGPT named in response was recorded:
- “Who is the best chimney sweep in Denver, Colorado?”
- “I need my chimney cleaned and inspected before winter. Which local chimney company in Denver, Colorado should I call?”
- “What is the most recommended chimney sweep company in Denver, Colorado?”
- “My chimney needs repair. Who is a trustworthy chimney repair company near Denver, Colorado?”
Inside the Denver data
- 289 Google reviews sit behind the listed names, at an average of 4.9 stars.
- Compared with the edition-wide average (52%), Denver's 58% sits above the line.
- However the question was phrased, CrownUp Pros kept coming back — 4 of 4 checks.

Common questions about the Denver list
Does ChatGPT recommend many chimney sweeps in Denver?
Very few. Of the 43 Denver-area companies we benchmarked in August 2026, only 25 were ever named across 4 checks — 58%. The rest never came up.
Who comes up most on the Denver list?
Right now, CrownUp Pros — recommended in every one of the 4 checks, and the only company at that level in Denver.
Why don't you rank the Denver companies 1, 2, 3?
A rank would be a made-up level of precision. ChatGPT answers slightly differently every time, and with 4 checks a company can only score 0 to 4. Several usually tie at the top, so we show the score and list tied names alphabetically rather than choosing between them.
Which questions produced the Denver list?
We asked 4 homeowner-style questions, such as "Who is the best chimney sweep in Denver, Colorado?", and logged each company ChatGPT named in response. All the phrasings we used are shown above.
Is a spot on the Denver board for sale?
Never. The board is measured, never sold: the only way on is to be named by ChatGPT in our checks. Money cannot buy a place on this list. Anything advertised alongside it is labeled as advertising.
Do Google reviews decide the Denver list?
No — the grouping comes only from how often ChatGPT named each company in our checks. We show Google ratings for context: the Denver board averages 4.9 stars across 289 reviews.
Every company we checked in Denver
The tiers above show the companies ChatGPT actually named.

Every company we checked is listed below, alphabetically. A listing here is not a recommendation from ChatGPT. It only means the company was part of the pool we measured. The ones ChatGPT kept naming are in the tiers above.

New to Denver? These chimney sweeps 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.
Just opened a company in Denver? You can be the first one here.
Tell us who you are and we'll add you to this section — free. It is not a ranking and it will never say you are ranked, because you are not: you are new. When we re-run the benchmark, a real spot on the list above is something you earn, not something we hand out.
