What this listing does and does not tell you

Diamantes Construction LLC appears on North Carolina’s septic licensing records as a certified septic installer, 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 April 30, 2024 — 2 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.

To confirm the licence is current today, check with the certification board, or your county environmental health office. Step by step →
