Commercial Fire Alarm & Security in League City, TX
Fire Alarm Systems for a Growing League City
League City is one of the fastest-growing cities in Texas, with more than 110,000 residents and a large share of its land still undeveloped. That means new offices, retail, medical buildings and tenant improvements, and every one of them needs a fire alarm system that's designed, permitted and inspected correctly.
New construction and tenant improvements. Avenger works with general contractors on League City projects from plan review through final inspection. We coordinate rough-in and trim-out around your schedule and hand over complete documentation at closeout.
Working with the League City Fire Marshal's Office. Fire alarm work in League City is overseen by the city's Fire Marshal's Office, part of the League City Fire Department. Submittal requirements can change, so we confirm current requirements with the Fire Marshal's Office at the start of every project rather than finding out at inspection.
Monitoring and service. Once your building is open, we provide 24/7 monitoring, annual inspections and repairs, so you have one local company for the life of the system.
