Several factors will play into the cost to remove your old house alarms. These are the main factors to consider when planning your budget.

Types

One of the main factors affecting your cost to remove burglar alarms is the type of alarm system. Wireless systems are the least expensive and can even be free to remove, as many offer DIY-friendly removal. Here are the average costs for removing each type of alarm system.

Alarm TypeDescriptionAverage Cost
Wired Alarm SystemHardwired into the home’s electrical system, often with sensors in walls, ceilings, and doors. Removal requires disconnecting wiring and patching holes.$150–$500+
Wireless Alarm SystemBattery-operated or plug-in components that connect via Wi-Fi or radio signals. Easier to remove with minimal wall damage.$0–$150
Smart Home Security SystemIntegrates with smart home devices like cameras, doorbells, and automation systems. May require reconfiguring home network settings.$100–$400+

Size of the System

If you have multiple security camera locations, sensors, and keypads for your alarm system, this can drive up costs if you’re hiring a professional electrician. Here are the average cost ranges for small, medium, and large systems.

System SizeDescriptionCost for Removal
Small SystemFive or fewer sensors, one keypad, wireless or minimal wiring$50–$200
Medium SystemUp to 10 sensors, one to two keypads, some or all components are wired$150–$400
Large System10+ sensors, two or more keypads, wired throughout the home$300–$500+

Labor

Hiring a licensed local electrician to remove an old house alarm system costs $50 to $100 per hour. Some professional electricians may also charge hourly minimums and trip fees, so consider bundling this relatively simple task with other electrical fixes or installations.

Aside from covering your electrician’s fees, these are a few other ongoing costs to consider.

Cancellation Fees

If your alarm system is tied to a monitoring service, you may face early termination fees, depending on the terms of your contract. Some providers also require written notice to cancel your contract, so be sure to review the requirements before you remove the old house alarms.

Disposal Costs

Some municipalities may charge fees for disposing of electronic waste, including old alarm system components like control panels, sensors, and cameras. Certain businesses offer free recycling for electronics, so be on the lookout for options in your area.

Repairs

Removing an alarm system may leave holes in walls, ceilings, or door frames that need patching and repainting. Wireless systems generally cause less damage, while wired systems may require more extensive repairs.

Insurance 

If your homeowner’s insurance plan had a discounted rate for your alarm system, you’ll see a rate increase of around 5%, or the previous discount amount. If alarms were specified in your home security risk assessment, then you may need a new evaluation for a potentially higher rate.

New Security Measures

Removing old house alarms without a backup solution leaves your home vulnerable to criminals, so it’s wise to invest in other home security upgrades, such as smart locks, motion-sensor lights, or a replacement alarm system to maintain home security after removal.

DIY House Alarm Removal vs. Hiring a Pro

Removing a house alarm system yourself can be a cost-effective option, especially for wireless or unmonitored systems that don’t require extensive wiring work. Many wireless alarm components, such as sensors, keypads, and cameras, can be easily detached without professional help. If you’re comfortable with basic home repairs, you can patch small holes left behind by wall-mounted devices, avoiding the extra cost of hiring a handyperson.

By forgoing hiring a professional electrician, you can potentially save $50 to $100 per hour in labor charges, plus any additional trip fees or minimum charges. However, if your alarms are wired into your home and you’re not skilled and comfortable with electrical work, then it’s the right time to hire an electrician. A professional electrician can ensure the system is fully deactivated and that all components are removed safely. While hiring a pro increases the overall cost, it provides peace of mind and prevents any potential damage or safety risks.

Cost of Common House Alarm Removal Add-Ons

If you’re bringing in a professional electrician to remove old house alarms, you can save on trip fees and potentially get bundled discounts by booking other services during the same visit.

Here are some of the most common electrical jobs to consider:

Tips to Reduce Costs For House Alarm Removal

Follow these tried-and-true tips for lowering the cost of home alarm system removal.

  • DIY any necessary repairs after removing the alarms, such as patching the drywall.

  • When replacing your house alarms, look for home security companies that offer free removal upon installation of a new system.

  • If you're planning renovations that require drywall work or electrical adjustments, consider scheduling alarm removal at the same time for potential discounts on bundled services.

  • Ask the right questions before hiring an electrician, including rates, fees, and bundled service discounts.

  • Interview at least three professional electricians to secure the best rate.

Frequently Asked Questions

Many homeowners wonder whether home security signs and decals actually deter crime. The truth is, while security signs may help deter burglars, they are not the most effective standalone solution. What’s more, using fake security signs can have legal consequences in some areas, especially if they falsely advertise professional monitoring. For the best possible protection, combine security signs with cameras, motion-activated lights, and a functioning alarm system.

No, wired systems are not obsolete. While many people assume that wireless systems are superior, wired alarms still have their advantages, including a stable connection that doesn’t rely on wireless signals, making them less susceptible to interference or hacking. They also don’t require battery replacements, reducing maintenance concerns. Wireless systems have improved in durability and signal strength, but for those prioritizing reliability and security, a wired system is still a great choice.
