construction & installation

How does C Spire Fiber get to my home?

In most cases, construction crews will lay fiber optic cable around your neighborhood, and then, we’ll dig a shallow, thin trench from the street to the side of your home to bring the cable close enough for installation. While it creates some temporary dirt and dust, laying fiber optic lines in the ground provides the most reliable connection possible.

What should we expect in our neighborhood during the construction process?

Here’s what happens next.

1. Utilities will mark their underground electric, gas and water 1 lines with paint.
2. Small holes will be dug to allow structure placement.
3. Horizontal lines will be drilled to connect the holes together.
4. The main fiber lines will be installed.
5. We will schedule home installations for customers who have completed their orders.

Why is construction necessary in my yard?

In order to bring service to a neighborhood, much like local gas, electric, water, and other cable or internet service providers, we’re laying our infrastructure throughout your municipalities’ right-of-way. This is an area out near the street that is designated for such services by law.

Some residences will have a handhole placed near the edge of the yard. This handhole provides our engineers with access to the main fiber optic line that runs through your neighborhood.

We’ll be sure to restore all grass, flower beds, etc. in your yard to the way it was before once the entire construction process is complete.

Who should I contact if I have questions about construction near my home?

The crew working directly in your neighborhood is the best point of contact regarding construction. We’ll provide their direct contact information before construction begins via email and direct mail.

When will C Spire Fiber Internet be connected to my home?

Once construction is complete on your street, and you’ve placed your order, a C Spire crew will bring the fiber optic cable up to the side of your residence. If you haven’t already scheduled an installation appointment, we’ll contact you to schedule your interior installation.

Can you utilize existing wiring in my residence?

In many cases, yes. We’ll test any existing wiring to make sure it can deliver the full potential of your new gigabit internet connection. If your residence’s existing wiring isn’t usable, our professional installation technician will discuss wiring options with you at the time of installation.

If I need new wiring, what type of cable will you use?

To bring you the full speed and bandwidth potential of gigabit C Spire Fiber Internet, we use Cat6 Ethernet cabling. We’ll provide and install this cable for you during your installation appointment. Alternatively, you can have an electrician or other licensed professional install this for you at your convenience and expense.

What equipment is placed on the exterior of my residence?

A utility box about two times the size of a shoebox will be placed on the side of your home, typically adjacent to your home’s main power supply. This utility box houses a piece of equipment called an ONT (Optical Network Terminal) that turns the fiber optic light impulses into a format that can be transmitted across more traditional Ethernet (network) cable.

When will my services be installed?

If we already have fiber in your neighborhood, you’ll be able to schedule your installation appointment when you place your order online. If we’re currently adding fiber to your neighborhood, we recommend ordering now so you can schedule your installation as soon as construction is completed.

How long will my installation take?

Most customers are installed within two hours although the actual length of the installation can be impacted by several factors, including the size of your home, number of services ordered, condition of existing wiring, location of outlet(s) and more. Our professional installation technician will be more than happy to give you an estimate to make sure your installation doesn’t interfere with the rest of your day.

account & billing

Is my bill going to change after a promotional period?

No, unlike many of our competitors, we aren’t luring you in with a cheap price that jumps up after 12 months. The price you see when you sign up is the price you’ll pay for the length of your contract, except for local channel transmission fees or any upgrades you want to add.

When and how will I get my first bill?

We’ll send your first bill within 7-10 business days of your installation to the email address you provide, unless you choose for us to mail you a paper bill.

How do I manage my services online?

Log in to your account to view and pay your bill, update your email address, manage services and more. We also suggest downloading the My C Spire app so you can manage your account on the go.

How can I pay my bill?

Log in to your account or the My C Spire app to pay your bill. From there, you can also set up AutoPay to make paying your monthly bill even easier.

What happens if I subscribe to C Spire Fiber and then move to an area without fiber?

We’re constantly expanding our C Spire Fiber service area(s), but if you move to an area that we don’t serve, there’s no penalty for canceling your service. Learn more about the process for moving services.
