Commercial contractors for San Antonio facilities
Flux helps commercial facilities plan contractor work with a clear scope before work starts. We review the building use, occupied areas, access needs, and the trades needed for the job. Flux uses this to your team choose a practical plan for the building. For commercial projects in San Antonio, permit applications, plan review, fees, and inspection scheduling move through the City of San Antonio Development Services portal. We help keep contractor plans and project details organized so your facility team can track the next step.

How San Antonio commercial contractors plan building work
- Define the commercial areas that need repair, remodel, or build-out work.
- List building access rules, occupied spaces, and work hours before trades are scheduled.
- Match the contractor scope to the plans and documents needed for the project.
- Confirm who will answer site questions and approve changes for your facility.

POWER & AUTOMATION
Battery storage, EV charging, and robots that work.
Commercial buildings are adding batteries, chargers, and floor robots faster than most contractors can keep up. We design and install battery energy storage systems, handle utility interconnection, and build EV charging from a pair of stalls to a full fleet depot.
On the automation side, we deploy cleaning and security robots that pay for themselves in labor, then keep every piece of it running. Planning any of this? Get in touch and get a real number for your building.

THE CORE TRADES

HVAC, plumbing, electrical, roofing. The unglamorous work is most of the job, and slow contractors are where it costs you. Our mechanical crews handle installs and replacements, from rooftop units to boilers, chillers, and process piping.
Maintenance covers the rest: service calls, electricians, roofing, fire and life safety, landscaping, and snow. Not sure where to start? An energy audit finds the waste and funds the fix.
