How to choose a network cabling company

  1. Ask which licence, permits and inspections your job needs locally, and who arranges them.
  2. Ask for a site survey and a written quote that lists cable type, number of runs and testing.
  3. Make sure each run is tested and certified, and that you receive the results.
  4. Check whether the firm also installs and configures switches and Wi-Fi, or only the cabling.
  5. Ask for two or three references from clients of your size and industry, and call them.
  6. Get the scope, response times and price in writing before you sign, including how you leave and get your data back.

Questions to ask a network cabling company

  • Which licence do you hold for low-voltage work here, and will you pull the permit?
  • Which cable category and brand do you install, and is there a manufacturer warranty?
  • Will every run be tested and labelled, and will we receive the test results?
  • Who handles the network equipment and Wi-Fi after the cabling is in?
  • How do you handle work in occupied offices or after hours?

Do network cabling and installation companies outside San Rafael count in this ranking?

Yes, if they are within 40 mi of the San Rafael city center, our service radius for network cabling and installation companies. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.

Can network cabling and installation companies pay to rank higher on ITFirmsRanked?

No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.

What does a network cabling company do?

Network cabling companies design and install structured cabling (Cat6, fibre), racks, Wi-Fi access points and network equipment in offices, warehouses and new buildings.

How are network cabling and installation companies in San Rafael ranked?

By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does network cabling and installation, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.

Does network cabling need a licence?

It depends on where you are. Some states and provinces license low-voltage or limited-energy work (California’s C-7 low voltage classification and Washington’s limited energy specialty are examples) and many cities require permits. Ask the firm which licence and permits apply to your job.

What should we get when the cabling is finished?

Labelled cables and patch panels, test results for every run and a floor plan showing where each run goes. Those records make later changes and fault-finding much faster.
