Missouri Licensing Requirements

Questions to Ask Before Hiring

- Do you test and certify all runs?
- What is your warranty on installation?
- Can you provide a site survey and estimate?
- Do you handle both installation and termination?
Tips for Finding the Right Contractor
Always insist on certified test results for every cable run. Use Cat6a for future-proofing. Make sure your contractor labels every run at both ends — it saves hours of troubleshooting later.
