Frequently asked questions

How do I check that a fire protection company in Duncanville is licensed?
Search the company name or registration number in the Texas State Fire Marshal's Office public lookup (https://appscenter.tdi.texas.gov/reports/p/sfmo). Every company listed here shows its registration numbers and expiration dates, re-checked against state records on each data refresh.
What license does a fire protection company need in Texas?
Texas requires a State Fire Marshal's Office certificate of registration for each type of work: fire alarm (ACR), fire extinguisher (ECR) and fire sprinkler (SCR). Individual technicians must also hold SFMO licenses.
Does a company need to be located in Duncanville to work there?
No. Texas registrations are statewide, so companies based elsewhere in Dallas County or across Texas can work in Duncanville. Confirm the service area with the company.
