How we measured this

Which impact window company does ChatGPT recommend most in Charleston?

In the July 2026 measurement, NewSouth Window Solutions — it came up in every one of the 4 checks, more than any other company including New Beginnings Construction. Frequency of naming is the entire ranking.

Can a window company pay to be on the Charleston list?

No — and that's the point. Rankings are measured, never sold; no payment, sponsorship, or relationship puts a company here. Money cannot buy a place on this list.

What does it mean if a Charleston company isn't listed?

Absolutely not. The list only records who ChatGPT named in July 2026; skilled companies that haven't built AI visibility yet simply don't appear — until they do.

How often is the Charleston measurement re-run?

This edition was measured in July 2026. We re-run the same benchmark quarterly with the same methodology, so companies that improve their AI visibility can appear in the next update.

How did you measure which Charleston 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 about Charleston, and recorded every company it recommended. Companies named more often rank higher. We ran 4 checks for this market. 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.
