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.

  • “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?”

All 43 chimney sweeps in Denver, ranked by Google rating

The list above is what ChatGPT named when we asked. This is every chimney sweep we checked in Denver on August 21, 2026 — all 43 of them — put in order by their Google star rating and how many Google reviews are behind it. That order is Google’s, not ours, and it is not an AI result. Being on this list is not a recommendation. It only means we checked this chimney sweep. The ones ChatGPT kept naming are in the groups above.

35 more chimney sweeps we checked, with no Google rating to sort by

These are listed alphabetically. A chimney sweep with no rating, or only one or two reviews, is not put in order above. That is a gap in what Google shows, not a judgement about the work.

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.

New — not rankedFree listing · not measured, not scored, not a ranking

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.
