It depends on license level, location, schedule and whether the job is prevailing wage. The market pay on this page comes from public U.S. Department of Labor data; your rate is agreed per assignment and approved before anyone starts.
Do you check sprinkler fitter licenses and certifications?
Yes. We check credentials such as State sprinkler fitter or fire protection license (where required) and NICET Water-Based Fire Protection before a worker can be placed, and track expiration dates.
Can you staff prevailing-wage and Davis-Bacon projects?
Yes. SiteWorker handles certified payroll and prevailing-wage documentation for the workers it supplies.
How fast can sprinkler fitters start?
Fast. We've turned Friday requests into Monday crews. Exact timing depends on the trade, headcount and site requirements, and you'll get a real start date on our first call.
Can I set a minimum safety tier?
Yes. Your request sets the minimum tier: A, B or C. Only workers at that tier or higher can be placed on your site.
