Family owned since 1983 Our own technicians Why Telelink
Forty years in, we still do the work ourselves.
Telelink started in Sacramento in 1983 installing business phone systems. The technology changed, the approach did not. Today the second generation of the family runs the company, and the technicians who show up on your job work for us, not a labor broker.
- We plan around the people in the building. Most of our projects happen with residents at home, staff at their desks or students in class. We schedule, notify and clean up like it matters, because it does.
- We install what the spec calls for. We are not a dealer pushing one brand. If the drawings say Cat6A and Axis cameras, that is what goes in, tested and labeled.
- We leave you with documentation you can use. Test results for every cable, labeled as-builts and a closeout binder your IT team will still be using five years from now.
Who we work with
Every building type has its own rules. We know them.
Pulling cable is the easy part. Working around residents, HUD inspections, prevailing wage or a campus network that cannot go down is what makes a project succeed. Pick your building type to see how we approach it.

Reviews
What clients have said about working with us.
Excerpts from reviews clients left on Google over roughly the last ten years. Most of them describe phone, cabling, camera and service work rather than large construction projects, which is a fair picture of who was writing reviews at the time.
These guys handled my phone and phone system move along with wire our new office from top to bottom. When all others failed, such as AT&T, Telelink was there to pick up the pieces. Most important out of all the great things I could say, they took all my calls and emails, no matter what time of day or night, even on the weekend and holidays. They know what they are doing and get it done right the first time.
U.S. Certified SignersOffice move: phone system relocation and a full office cabling installationI had an issue with my cameras and called for help. He was able to get me on the schedule within the week. They came out, diagnosed the problem, and fixed everything within a couple hours. Very professional, affordable, and fast.
Evan KorisService call on an existing camera systemAfter switching telephone and internet from ATT to Comcast, I needed to have some phone and data lines moved. I called Telelink and immediately received a professional response. An appointment was efficiently scheduled to coordinate with Comcast. The technicians were friendly, capable, and extremely helpful in working through some glitches. After the service, I received an invoice which was honest and very reasonable.
