What this listing does and does not tell you

T-Square Development LLC appears on North Carolina’s septic licensing records as a certified septic installer and certified septic inspector, as published August 21, 2026. That is a statement by NC OWCICB that the licence was held when the record was compiled.

The record puts the first certification at January 30, 2021 — 5 years ago. Longevity is not a measure of quality, but it is a fact the state publishes and it is hard to fake.

It is not a rating, a review, an endorsement or a guarantee of insurance, price or workmanship — and licences lapse. Nothing on this page comes from the company itself, and no company pays to be here.
