Free listing Castillo Works
Castillo Works is a multi-trade Chula Vista operation — plumbing, HVAC, electrical, restoration, and construction — on a verified license carrying C-36 plumbing, B general building, and C-20 HVAC classifications. Its water heater page covers tank, tankless, heat pump, maintenance, and light-commercial work and names five equipment brands. Same-day repairs and installs are advertised. The site’s “since 1993” claim predates the 2008 license, which CSLB holds as a sole ownership.
