Phoenix has one of the deepest low-voltage contractor markets in the Southwest, which is good for buyers and confusing at the same time. The right partner depends on whether you are cabling a single tenant improvement, a warehouse, or a multi-building campus, and whether you want cabling alone or cabling bundled with security, access control, and managed IT. This guide covers eight structured cabling and low-voltage companies serving the Phoenix metro in 2026. Each entry lists what we could verify: Arizona ROC license (where public), specialty, and coverage.
This is the Phoenix-scoped companion to our national top structured cabling companies buyer's guide, which covers enterprise and multi-state players. If you are outside the Valley, start there. We have included Unió Digital because we serve Arizona statewide, and we have placed ourselves honestly in the middle rather than at the top. The order below spans project types; it is not a strict quality ranking.

How We Chose These Companies
The Phoenix low-voltage market is fragmented, and comparing firms on revenue or crew size misleads a single-site buyer. We evaluated each firm on:
- Arizona licensing: an active ROC low-voltage or electrical license for work over $1,000. We list the number where the company publishes it.
- Specialty fit: some firms are built for warehouse and industrial pulls; others for office tenant improvements or combined cabling-and-security scopes.
- Metro coverage and response: how fast a tech can be on-site across Maricopa County when a closet or run fails.
- Certification and testing: BICSI-certified installers and Fluke/OTDR certification on every drop.
- Ongoing service: whether the firm stays engaged after handoff or walks away at closeout.
1. Casa Tech Systems (CTS) — Best for Large Commercial and Industrial
Casa Tech Systems (CTS Electrical & Low Voltage) is a Phoenix contractor operating since 2000, specializing in structured cabling, fiber optics, outside plant, sound masking and paging, video surveillance, and wireless access point deployments. They carry manufacturer partnerships (Panduit Gold Partner, Corning NPI) that signal warranty-backed installation, and they handle industrial Ethernet and larger campus scopes many smaller firms refer out.
Strengths: Long Phoenix track record, industrial and outside-plant depth, manufacturer-certified warranty programs.
Watch-outs: Confirm current ROC license status on the state board; larger-firm engagement can be heavier than a small single-drop job needs.
Best for: Large commercial builds, industrial facilities, campus and outside-plant projects in the Phoenix metro.
2. Commercial Cabling Company — Best for Data Cabling and Fiber Splicing
Commercial Cabling Company is a Mesa-based contractor founded in 2014, holding Arizona ROC #291868 (CR-67). They install Cat5e, Cat6, and Cat6A copper, fiber optic backbone with fusion splicing, and MDF/IDF buildouts to TIA/EIA standards, with Fluke certification on all work. They serve the Phoenix metro, Southern Arizona, Nevada, and nationally.
Strengths: Published ROC license, fusion-splice fiber capability, multi-state reach for rollouts.
Watch-outs: Verify current license status and confirm crew certifications for your specific scope.
Best for: Businesses that need certified copper plus fiber backbone, MDF/IDF buildouts, or multi-site cabling.
3. Cabling Solutions Group — Best for Cabling Plus Security Combined
Cabling Solutions Group holds Arizona ROC #307417 and serves both Phoenix and Tucson with more than a decade in business. Their scope combines structured cabling and fiber with security cameras, door access control, audio/visual, and commercial electrical, which suits buyers who want the wiring and the security system under one contract.
Strengths: Published ROC license, combined low-voltage and security scope, dual-metro Phoenix and Tucson coverage.
Watch-outs: Broad service menus can mean varying depth by discipline; confirm the crew's cabling certification specifically.
Best for: Commercial buyers wanting cabling, cameras, and access control from a single Arizona contractor.
4. Phoenix Communication Solutions — Best for Office TI and New Construction
Phoenix Communication Solutions holds Arizona ROC #280299 and covers Phoenix, Scottsdale, Tempe, Mesa, Chandler, Gilbert, Glendale, and surrounding communities. They focus on Cat6 and Cat6A data drops, VoIP and wireless cabling, patch-panel organization and testing, and tenant-improvement and new-construction cabling.
Strengths: Published ROC license, broad Valley coverage, office and TI focus.
Watch-outs: Best fit for standard office and TI cabling; confirm capability for large industrial or outside-plant scopes.
Best for: Office tenant improvements, new commercial construction, and standard data-drop projects across the Valley.
5. Unió Digital — Best for Cabling Plus IT and Security From One Team
We have placed ourselves at #5 deliberately. We are an Arizona statewide contractor headquartered in Tucson, not a Phoenix-only firm, and we serve Phoenix commercial clients who want structured cabling, physical security, and managed IT owned by one accountable team rather than coordinated across three vendors. We hold Arizona ROC 327245 and ROC 333580 plus alarm license 25254-0, run certification testing on every drop, and stay engaged with clients through the life of the cabling system.
Strengths: Integrated cabling, IT, and security service after install; published ROC and alarm licenses; transparent project management.
Watch-outs: We are headquartered in Tucson and dispatch to the Phoenix metro, so for pure single-drop Phoenix service work a Valley-based crew may respond faster.
Best for: 20 to 500 employee Arizona businesses wanting one team for cabling plus IT plus security. See our structured cabling services
6. CableEX — Best for Cabling Plus Electrical and Boring
CableEX runs a Phoenix Valley field team (with a Denver headquarters) and more than a decade of experience. Their scope spans Cat5e/Cat6 cabling, fiber optic cabling and splicing, access control and video surveillance, commercial electrical, and directional boring, which is useful when a project needs both low-voltage and civil work.
Strengths: Combined low-voltage, electrical, and boring capability; broad Valley coverage.
Watch-outs: Out-of-state headquarters; confirm Arizona ROC licensing and local crew depth for your scope.
Best for: Projects that pair structured cabling with electrical or underground pathway work.
7. Phoenix Techforce — Best for Structured Cabling and Conduit

Watch-outs: Verify ROC license and confirm project references for larger scopes.
Best for: Phoenix commercial cabling projects needing certified copper and fiber.
What to Verify Before You Hire in Phoenix
The vendor decision affects your cabling for the next 10 to 15 years. Before you commit:
1. ROC license, verified on the state board
Low-voltage cabling in Arizona requires an active ROC license (commonly CR-67 / C-67) for work over $1,000. Ask for the number and verify it at roc.az.gov before signing. Do not accept a number on a proposal at face value.
2. BICSI-certified installers on your job
Ask how many of the techs who will actually be on-site hold BICSI Installer 1 or 2 credentials, not just whether the project manager is certified.
3. Certification testing on every drop
Insist on Fluke DSX (copper) and OTDR (fiber) certification on every run, delivered as a PDF at closeout. Sample testing or tone-and-probe is not certification.
4. Closeout documentation
You should receive certified test results, as-built drawings, rack elevations, and a labeling convention. Without them, future moves, adds, and changes cost 2 to 3 times more.
What Structured Cabling Costs in Phoenix
As a 2026 orientation for the Phoenix metro: Cat6 data drops in commercial work typically run $150 to $300 each, with the higher end reflecting long runs or hard ceiling access. Cat6A and fiber cost more; a terminated fiber drop generally runs $300 to $800. Service work (small adds, troubleshooting) commonly bills at $125 to $200 per hour with a minimum visit charge. For the full fiber breakdown, see our fiber optic installation cost guide.
Frequently Asked Questions
What does structured cabling cost in Phoenix?
In the Phoenix metro in 2026, commercial Cat6 data drops typically run $150 to $300 each, Cat6A and fiber cost more, and a terminated fiber drop runs about $300 to $800. Service and small-add work commonly bills at $125 to $200 per hour with a minimum visit charge. Actual pricing depends on drop count, cable category, and building access.
Do structured cabling companies in Phoenix need an Arizona license?
Yes. Low-voltage cabling work over $1,000 in Arizona requires an active ROC license, commonly a CR-67 or C-67 classification. Always ask for the contractor's ROC number and verify it at roc.az.gov before signing a contract.
Should I hire a Phoenix-only contractor or a statewide company?
For a single Phoenix site, a Valley-based contractor often gives faster response. For multi-site Arizona work, or when you want cabling bundled with managed IT and security, a statewide company with an integrated service model can be more efficient. Match the contractor to your footprint and scope.
How is this list different from the national structured cabling guide?
This guide is scoped to companies serving the Phoenix metro. Our national top structured cabling companies buyer's guide covers enterprise and multi-state integrators for organizations rolling out cabling across many states. Use the national guide for multi-state programs and this one for Phoenix commercial work.
How do I verify a Phoenix cabling contractor's license and certifications?
Ask for the ROC license number and verify it at roc.az.gov. Ask for BICSI ID numbers of the installers who will be on your job and verify them through BICSI's directory. For manufacturer warranty programs (Panduit, Corning, CommScope), confirm the certification with the manufacturer.
