How we measure who ChatGPT recommends
These rankings aren't opinions, votes, or paid placements. They are a record of what ChatGPT actually answered when we asked it — the same way a real homeowner would — who should put impact windows on their home.
Measured, never sold.
Money cannot buy a place on this list. No window company paid to appear here, no window company can pay to appear here, and advertising anywhere on this site will never change a measured ranking. If that ever stops being true, this site has no reason to exist.
The five steps, in plain language
- 1
We ask the questions real homeowners ask.
In each metro we asked ChatGPT for an impact window company 4 different ways — everyday phrasings like "Who is the best impact window company in my city?", "I want hurricane windows installed on my house. Who should I hire?", and "What is the most recommended impact window installer near me?". No trick prompts, no leading questions. Across 16 coastal metros, that came to 64 checks for this edition.
- 2
We record every company it names.
Each answer gets logged exactly as given. Each business ChatGPT names is credited to exactly one company — and when we can't tell for certain which local company it meant, no one gets the credit. No company is ever double-counted.
- 3
Frequency sets the rank.
A company recommended in 4 of 4 checks ranks above one recommended in 2. Asking the same question several ways is what makes the result dependable. The Google star ratings and review counts shown next to each company are context from Google — they play no part in the ranking.
- 4
We publish the top of the list — and only the top.
Each metro page shows the companies ChatGPT actually recommended, most-recommended first. We never publish a bottom list and never name who didn't make it. A company that isn't listed simply didn't come up in this edition's answers.
- 5
We re-run it quarterly.
The same benchmark, the same way, every quarter. Companies that improve their AI visibility can appear in the next edition — and the run date is printed on every page. This edition: July 2026.

What this is — and what it isn't
Being on this list means ChatGPT recommended that company when we asked, in this edition, in that metro. It is a measurement of AI visibility — not a judgment of the quality of anyone's installs, and not a claim that unlisted companies are worse at what they do. AI answers also change over time, which is exactly why we re-measure quarterly and date every edition.
Common questions
How did you measure which impact window companies ChatGPT recommends?
We asked ChatGPT the questions real homeowners ask — like "Who is the best impact window company in my city?" and "I want hurricane windows installed on my house. Who should I hire?" — 4 different ways in each of 16 coastal metros, and recorded every company it recommended. Companies named more often rank higher. That came to 64 checks for this edition, compared against the 184 coastal window companies in our tracked dataset. Each business ChatGPT names is credited to exactly one company — when we can't tell for certain which local company it meant, no one gets the credit.
Can a window company pay to be on this list?
No. This list is measured, never sold. A company appears here only if ChatGPT actually recommended it when we asked. Money cannot buy a place on this list.
What are impact windows, and why do people ask about them?
Impact windows — often called hurricane windows — use laminated glass and reinforced frames built to stand up to windborne debris, so a storm doesn't turn a broken window into a destroyed home. They're one of the biggest storm-protection upgrades a coastal homeowner can make, and many insurers offer wind-mitigation discounts for impact-rated windows — Florida insurers are required to offer those credits — so it's worth asking your insurer what qualifies.
What does it mean if a company is NOT on this list?
It means that when we asked ChatGPT for an impact window company in that company's metro, that company never came up. That says nothing about the quality of their installs — only that homeowners who ask AI for a recommendation are being sent somewhere else.
How often is this updated?
We re-run the same benchmark quarterly with the same methodology, so companies that improve their AI visibility can appear in the next update. This edition was measured in July 2026.
