Landline Phone Service questions, answered by experts

Having a landline is often worth paying for, if only for the peace of mind it provides. While some homeowners opt for cell service and internet only for communication, cell towers and internet lines can get knocked out of service during storms or natural disasters. Landlines can continue to work even if the power goes out, and telephone lines are more likely to continue to work in emergency situations. Paying monthly for a landline might seem like an unnecessary expense until you need it, at which point it could be invaluable.

Regular software updates, checking for loose connections, and protecting wires from physical damage help prevent issues.

Typical costs for installing or repairing phone wiring range from $150 to $500, depending on the complexity and extent of the work involved.

The length of coax cable can affect the signal. Coax cables and their connectors all have a small amount of electrical resistance, which means that the longer the cable and more connectors in the system, the weaker the signal strength. In most homes, the signal loss is tiny, but systems with coax cable lengths over 100 feet will likely experience signal troubles.

As long as your landline is corded, meaning your telephone has a handset wired to a base unit on the wall, it will work during a power outage. Cordless phones won’t work without power, and cell phones will run out of battery eventually, so having a corded landline can be vital if your area loses power frequently or for long periods.
