How it works

One morning a year. We handle the rest.

From booking to filed report, staying compliant takes almost nothing on your end.

  1. 01

    Book in minutes

    Pick a service and an open time online, or call us. You get instant confirmation and a realistic window — no phone tag.

  2. 02

    We test — and fix

    We verify your assembly with a calibrated gauge. If it fails, we can repair or replace it and re-test on the same visit.

  3. 03

    Filed & reminded

    We file your County of Hawaiʻi–compliant report for you, then remind you before next year's test is due.

Not sure which service you need?

Tell us what you have — an irrigation line, a fire assembly, a whole property of devices, or a test that just failed — and we'll point you to the right one and a clear price.
