What's WSFP?
WSFP began in contract fire protection. According to its anniversary page, the business dates back to 1985 and today operates 45+ offices in the western United States. It says the range of buildings it protects goes from small businesses and schools all the way up to hospitals and large plants. That covers many kinds of buildings.
A large fire and life safety group, APi Group, is the company's owner. The APi company profile records the 1989 deal and says there are now over 40 sites in the United States. Since the two numbers differ slightly, check the locations page for your city. APi also says technicians train at centers the company runs in Denver, Kansas City, Houston, and Albuquerque.

Western States fire protection services
On its home page, the company says everything is done by the firm itself. Your automatic sprinklers can all be handled by one firm, from design through install, inspection, and upkeep. No juggling of subcontractors is needed. You call one place when a part fails, and nobody can shift the blame.
For special hazards, it builds custom suppression too. Those cover spaces where water isn't the best choice, like chemical, industrial, or high tech areas. It also installs fire alarms and provides 24/7 monitoring for both alarm and security systems. The list also shows emergency service and repair as 24/7. Older buildings can get retrofit work to bring what's there up to date.
A set schedule tells you when to check sprinklers. What gets tested is covered in the fire sprinkler inspection guide. Your dates depend on local rules, so ask the fire marshal in your town, the AHJ, the authority having jurisdiction.
USS Lexington sprinklers
How crews handle cramped conditions is clear from one project. WSFP installed standpipes and a wet pipe sprinkler system aboard the USS Lexington. The ship is a museum in Corpus Christi, Texas. Because a wet pipe system holds water at all times, the spray begins the moment a head opens.
The job lasted 120 days, according to the project write up. Crews put in more than 400 sprinkler heads. Each cut through the steel walls was worked out with museum staff in advance. Ask for that kind of planning if your building remains open while work goes on.
Questions to ask a sprinkler contractor
- Find out who signs the sprinkler drawings and the water flow math for your building. The permit office will ask about it.
- Check whether the bid includes the permit and the fire marshal's final test. That way, no surprise bill shows up at the end.
- Find out which visits the service plan includes after install. Check it against the fire inspection frequency chart so you don't miss anything.
- Ask how special hazard systems are maintained. Different tools are often needed for them.
- Ask which office will take care of your service once the work is finished. That office might not be the one that built it.
