Why businesses still wire with Ethernet
Wi-Fi is convenient, but a cable to the desk is still the most dependable connection for most offices:
- Speed and low latency: steady throughput for video calls, VoIP and large file transfers.
- Consistency: no interference from walls, neighbors or crowded wireless channels.
- Security: someone has to be physically plugged in to reach the network.
- Wi-Fi needs it too: every business access point is fed by an Ethernet cable, usually with PoE power.
Typical Ethernet installation costs
These are typical market ranges for commercial work in 2026. Your price depends on the site, so treat them as a planning guide, not a quote.
| Cost item | Typical range | What it covers |
|---|---|---|
| Cable | $0.50 – $4.00 per foot | Cat5e at the low end, Cat6A and plenum-rated cable at the high end |
| Installed drop (port) | $100 – $300 per drop | Cable run, jack, wall plate, patch panel termination, testing and labeling |
| Labor | $75 – $150 per hour | Varies with access, ceiling type, building rules and time of day |
| Network equipment | $500 – $5,000+ | Switches, router or firewall, patch panels and racks |
| Design and planning | $500 – $2,500 | For larger multi-room or multi-floor networks |
Our own standard labor rate is $75 per hour. Larger projects are quoted at a fixed price after an onsite survey.
Cost by project size
| Project | Number of drops | Typical total |
|---|---|---|
| Small office or home office | 1 – 10 | $1,000 – $4,000 |
| Medium business | 15 – 50 | $5,000 – $20,000 |
| Large office or multi-floor | 50 – 200+ | $25,000 – $100,000+ |
Totals include basic equipment such as a patch panel and switch. They do not include computers, phones or internet service.
What changes the price
Cable type
- Cat5e: lowest cost, supports 1 Gbps. Fine for small, simple setups.
- Cat6: the usual choice for offices. 1 Gbps to 100 m, and 10 Gbps on shorter runs (up to about 55 m).
- Cat6A: 10 Gbps to the full 100 m and better for high-power PoE such as Wi-Fi 6E and Wi-Fi 7 access points. Thicker and pricier to pull.
- Fiber: for backbones between floors, buildings or long distances.
Building and access
- Retrofits cost more than new construction: fishing cable through finished walls takes time.
- Drop ceilings are easier than hard lid ceilings, concrete or open structure that needs conduit.
- Plenum spaces require plenum-rated cable, which costs more per foot.
- Building rules (escorts, after-hours windows, union or permit requirements) add time.
Number of drops and run length
More drops mean more material and labor, but the cost per drop usually falls as the project grows because setup time is shared. Runs over 90 m need a closer switch or a fiber link.
Equipment
Managed switches, PoE switches and business firewalls cost more than consumer gear but give you monitoring, VLANs and power for access points and phones.
Costs people forget
- Patch panels and racks: $100 – $1,000 depending on size
- Cable management (D-rings, J-hooks, Velcro, labels): $50 – $300
- Testing and certification reports: $200 – $1,000 for a full certification report
- Removing old, abandoned cable when you move or upgrade
- Firestopping where cables pass through rated walls
Ethernet vs. Wi-Fi: cost and value
| Ethernet | Wi-Fi | |
|---|---|---|
| Speed and stability | Higher and steady | Varies with distance and interference |
| Upfront cost | Higher (cable to each spot) | Lower per user |
| Security | Physical access required | Depends on configuration |
| Best for | Desks, phones, printers, cameras, access points | Laptops, phones and mobile devices |
Most offices use both: Ethernet for fixed devices and to feed the access points, and Wi-Fi for everything that moves. See our Wi-Fi installation service.
DIY or professional installation?
A single cable to a nearby room is a reasonable DIY job. For an office, professional installation is usually worth it: cables are run to standard, terminated on a patch panel, tested, labeled at both ends and documented, so future moves and troubleshooting are quick.
How to keep the cost down
- Get two or three written quotes based on a site walkthrough, not a phone estimate.
- Run cable during construction or renovation, while walls and ceilings are open.
- Use existing pathways, conduit and cable tray where they are in good shape.
- Choose Cat6 unless you need 10 Gbps over long runs or high-power PoE.
- Add spare drops now. One extra cable during the project costs far less than a return visit.
- Bundle related work such as access points, cameras and phones into one project.
How we price Ethernet work
For small jobs we bill time on site at our standard rate. For projects, we do an onsite survey first, then give you a fixed written quote with the drop count and cable type, so there are no surprises. Every job is tested and labeled, and closes with photos and a written completion report. See data cabling and Ethernet cable installation.
Frequently asked questions
How much does it cost to install one Ethernet drop?
Usually $100 to $300 per drop, installed and tested. The run length, cable type and how hard the walls and ceilings are to work in make the difference.
How much does it cost to wire a small office?
A small office with about 10 drops typically costs $1,000 to $4,000, including a patch panel and basic switch.
Do I need Cat6 or is Cat5e enough?
Cat5e supports 1 Gbps and works for basic needs. Cat6 is the usual choice for offices because it costs only a little more and supports 10 Gbps on shorter runs. Choose Cat6A for 10 Gbps on long runs or for high-power PoE access points.
Is it cheaper to install Ethernet during construction?
Yes. With walls and ceilings open, cable is faster to run, so labor is lower.
Can I mix Ethernet and Wi-Fi?
Yes. Most offices use Ethernet for desks, phones, printers and access points, and Wi-Fi for laptops and mobile devices.
Can I install Ethernet myself?
For a single cable in a home, yes. For an office, a professional install gets you standard terminations, testing, labeling and documentation.
