The average labor cost to remove old 120-volt house alarms ranges between $100 and $200. This cost accounts for hiring a licensed electrician who charges around $75 to $100 per hour and the task usually taking 1 to 2 hours to complete.
If the system is more complex, such as being interconnected with other alarms or hard-to-access wiring, the cost can increase to around $250 to $300. This estimate includes any potential service fees and minor adjustments required during removal.
Why Hire a Professional?
120-volt house alarms are hardwired into your home’s electrical system, meaning their removal involves handling electrical connections. Hiring a licensed electrician ensures Safety Compliance and Efficiency.
What Affects the Cost?
- Size and Complexity of the System:
- Simple systems with one or two alarms are cheaper to remove.
- Larger systems with multiple interconnected alarms or backup batteries take more time and effort.
- Location of the Alarms:
- Easily accessible alarms on the ceiling or wall are quicker to remove.
- Hard-to-reach alarms (e.g., in high ceilings or tight spaces) require additional equipment or time.
- Condition of the Wiring:
- Old or corroded wiring require extra work to ensure safe disconnection.
- If the wiring needs to be replaced or capped off, the cost increases.
- Additional Services Needed:
- Wall Patching: Removal may leave holes where the alarms were mounted. Patching and painting can add $100–$150.
- System Replacement: If you’re upgrading to a new alarm system, the electrician might bundle installation costs.
