The contractor you call when failure isn't an option.
Zion Fire Protection is a Texas-licensed, women-owned, owner-operated fire-protection contractor headquartered in McKinney since 2018, with statewide reach across Texas. We design, install, inspect, monitor, and service every fire-protection system in your building under one account. Same technicians. Same reports. Same standard, every visit.
The short version
Zion Fire Protection was founded in McKinney in November 2018 by Joel Sadowsky, after fifteen-plus years in the Texas fire-protection trade. Today we run fire alarm, sprinkler, monitoring, ERCES, special hazards, ITM, and the walk-in fire-extinguisher service the McKinney office is best known for — with 131 five-star Google reviews and zero BBB complaints in three years.
The company is women-owned, owner-operated, and Texas-licensed across all three fire-protection contractor categories (alarm, sprinkler, extinguisher).
Why we exist
Most fire-protection contractors are run by people who can't sign for the work. That gap shows up everywhere — in how systems get designed, in how AHJs get handled, in how training gets done, and in how customers get treated when something goes wrong.
Zion is run by a NICET III–credentialed contractor who can do the work, sign for the work, and explain the work to the inspector. Every technician on a Zion job site is on a documented NICET certification ladder — apprentices included. That's the difference between a fire-protection company and a fire-protection contractor.
The operating model
One company. One report. One bill. We replaced the four-or-five-contractor model that most Texas building owners run today:
- One company. Every fire system in your building — alarm, sprinkler, monitoring, kitchen, clean agent, ERCES — under one Zion account. One account manager. One name on the COI.
- One report. A single AHJ-ready report after every visit, covering everything tested that day, in the same format. Delivered same-day, not three weeks later.
- One bill. One monthly invoice for your whole portfolio. Itemized clearly. Your CFO gets a single "fire protection" line item; your AP team stops chasing five contractors for backup.
Who runs Zion

How we train the people who work on your building
Zion Fire Academy is the in-house apprenticeship program that staffs every Zion job site. Real classroom hours. Documented NICET progression. A career ladder mapped to a paycheck. The person who walks into your building has been trained by us, mentored by a NICET III lead, and put on a path to credentialing — not borrowed from a sub.
This is the part most national fire-protection companies can't credibly claim. Read the program at Zion Fire Academy.

Two divisions
Zion runs two divisions under one company:
- General fire protection — fire alarm, sprinkler, suppression, ITM, monitoring (this site)
- BDA / ERCES Division — first-responder radio coverage to NFPA 1225 and IFC §510. Dedicated technicians, dedicated tools, dedicated team. Visit the BDA division →
How we work
Three rules for every job:
- Code-first. Cite the standard. Cite the section. Cite the Texas adoption. If we can't show you the code reference, we don't recommend the work.
- NICET on every site. A NICET-credentialed lead is on every project at every site visit. Apprentices learn, they don't lead.
- Same-day reporting. Your AHJ-ready report lands the same day the inspection happens. Not three weeks later. Not "we're working on it."
