• What categories of cabling do you install (Cat6, Cat6a, fiber)?
• 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?

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.
