Low-Voltage Subcontractor for General Contractors in Texas

You need a low-voltage sub who shows up, communicates, and doesn't create headaches. Lumitra works alongside general contractors on new construction and tenant improvement projects across San Antonio, Austin, and Central Texas — and we run our work the way a good sub should.

What GCs Appreciate About Lumitra

We Know How Construction Works

We coordinate with your schedule, not the other way around. We're on site when we're supposed to be, we flag issues early, and we don't hold up your CO with last-minute problems.

Clean RFIs and Submittals

Our submittals are complete and our RFIs are clear and specific. We don't send vague questions — we come with options and recommendations.

One Sub for All Low-Voltage Scope

Data cabling, network rooms, AV rough-in, access control, security cabling — one contract, one point of contact, one crew. No coordinating between three different subs for low-voltage work.

Documentation That Satisfies the Owner

At project closeout, we hand over software-enabled as-built documentation that actually impresses owners and facilities teams. That's a detail that reflects well on your team.

Project Types

  • Ground-up commercial office, medical, and mixed-use
  • Tenant improvement and interior build-outs
  • Campus expansion and multi-building projects
