Tustin combines established industrial corridors with the Tustin Legacy redevelopment, giving us everything from 1970s warehouses to new mixed-use and medical buildings.
New construction and tenant improvements drive installation work here as much as repair.
Tustin is roughly 25 minutes from Yorba Linda, and we handle both service calls and coordinated installation work with GCs on TI projects.
For new installations we confirm rough opening, headroom, and power before the crew mobilizes so schedule commitments hold.

2025 California Energy Code (Title 24, Part 6)
The current energy code took effect January 1, 2026 and carries envelope and air-leakage requirements that affect how new and altered openings are specified — insulated sections, weather seals, and dock seals get reviewed at permit rather than after the fact.

Loading dock edges and floor openings must be guarded, and equipment used at those edges has to be maintained in safe operating condition. Worn leveler lips, missing toe guards, and dead vehicle restraints are the findings that surface during inspections.

Newer doors still need scheduled PM to hold alignment.
