Frequently asked questions

How do I check that a fire sprinkler contractor in Spring 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 sprinkler contractor need in Texas?
Companies doing this work must hold a Texas SFMO Fire Sprinkler Certificate of Registration (SCR). 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 Spring to work there?
No. Texas registrations are statewide, so companies based elsewhere in Harris County or across Texas can work in Spring. Confirm the service area with the company.
