How this page is built

Nobody pays to appear on this page, and position cannot be bought. A company is listed only where the official register showed it holding a current license when we checked on September 4, 2026.

Ranked by workers' compensation cover and years licensed.
Left off anything expired on the date we checked, or carrying any status other than current.
Not published at all until at least 3 electrical contractors pass that check. At most 10 appear - a cut through the ranking, not a further test.

The full method, including what each register does and does not publish.

Napa County electrical licensure at a glance

California licenses contractors by classification and CSLB publishes one on every record, so supply can be counted exactly: 98 active C-10 electrical licenses in Napa County, 4 of them registered in St. Helena. CSLB also publishes a real original issue date, which Washington's registry does not, so tenure is measurable here: the median St. Helena license has been held 34 years, and the longest-standing one dates to 1980. 1 of St. Helena's 4 licenses (25.0%) carries current workers' compensation cover in CSLB's file. That is employee injury cover, not liability insurance, and a blank usually means an owner-operator with no employees - lawful, and not a mark against anyone. The contractor bond is not a signal here: 98 of the county's 98 licenses carry the same $25,000 bond California sets by statute. 6 county licenses reach their expiration date within the next 90 days. CSLB cannot link straight to a license record, so every listing above shows its number for you to type into CSLB's license lookup. How we verify.

Why is a company not on this list?

A company appears only when we can match it to a current record in the register this page is verified against - 4 companies passed that match for St. Helena. A credential that is expired or suspended, or a business we cannot conclusively match to a current record, never appears. A listed business that believes its information is wrong can reach us through the contact and corrections page at homversa.com/contact. How current each date is, and what happens when a credential lapses, are explained on our methodology page.
