Before You Hire a Low-Voltage Contractor

How to Use This Checklist

Before hiring a low-voltage contractor, ask questions about the products being installed, the quality of the workmanship, and what is actually included in the estimate.

Check each item as you discuss it with the contractor. Mark N/A for services that are not part of your project.

The lowest price does not always represent the best long-term value.

    Remember: Cheap Isn't Always the Cheapest

    A lower installation price can become more expensive when poor-quality materials, improper installation practices, inadequate testing, or incomplete project planning result in repairs, service interruptions, and premature replacement.

    Ask questions before you hire. Understand what you are paying for. Choose long-term value.

    Educational checklist only. Not every question applies to every project. Licensing, insurance, permitting, and installation requirements depend on the work and applicable laws and codes. Customers should independently verify contractor credentials.

    Common questions

    What should I ask a low-voltage contractor before hiring them?

    Ask about their license and insurance, the cable and connectors they will install, how the cable will be supported, whether firestopping and testing are included, and what the written scope, exclusions, warranties and change-order process say. Then compare estimates on quality and completeness, not just the final price.

    What license does a low-voltage contractor need in Florida?

    Low-voltage (limited energy) work is licensed by the Electrical Contractors' Licensing Board, part of the Florida Department of Business and Professional Regulation. A limited energy systems specialty license covers it, and unlimited electrical, residential electrical and alarm system contractors may also do this work. Ask for the license number and check that it is active yourself on the department's site, myfloridalicense.com.

    What is copper-clad aluminum (CCA) cable, and why does it matter?

    CCA is cable with an aluminum core and a copper coating. The TIA and ISO/IEC standards for Category 5e, 6 and 6A structured cabling require solid copper conductors, and CCA does not meet that requirement.

    Is cable testing the same as cable certification?

    No. A basic test checks wire map and continuity: that each wire reaches the right pin, with no opens or shorts. Certification measures the installed link across a range of frequencies, compares the results with the TIA or ISO limits for its category and reports a pass or fail. Ask which one the estimate includes.

    Is the lowest estimate the best value?

    Not always. A lower installation price can cost more later when poor-quality materials, improper installation, inadequate testing or incomplete planning lead to repairs, service interruptions and early replacement. Compare what each estimate includes before comparing totals.
