A veteran-owned, Tennessee-licensed contractor focused on commercial fire, life-safety, and low-voltage systems.
Who We Are
Extreme Custom Technology (ECT) is a veteran-owned commercial contractor specializing in fire alarm, fire suppression, and low-voltage systems. Our focus stays on commercial and regulated environments — the kind of work where code compliance, accurate documentation, and long-term system reliability aren't optional.
We work directly with facility owners, general contractors, and the authorities having jurisdiction on every project, from initial design through the inspection cycles that follow. That means fewer surprises during inspections, clearer records when they're needed, and systems that keep performing after installation day.
Regulated systems don't leave room for shortcuts. We build and service every system to code, not just to pass inspection.
We work exclusively on commercial-grade fire, life-safety, and low-voltage systems — including multifamily and hospitality properties — not single-family homes or consumer alarm work.
We communicate directly with inspectors and code officials, so nothing gets lost between design, installation, and inspection.
