How often do smoke and CO detectors need to be replaced?

Most smoke alarms should be replaced every 10 years, while CO detectors typically last 5 to 7 years depending on the model. Over time, sensors lose sensitivity even if the device appears to work. We check manufacture dates and recommend updates when needed. Replacing them on time is one of the easiest ways to protect your household.

Should detectors be hardwired or battery-operated?

Both are effective, but hardwired units offer greater reliability and can be interconnected across your home. We recommend hardwired alarms with battery backup, so you’re covered during an outage. Our team installs both types and helps determine the best fit based on layout, access, and local code. No matter the option, we’ll make sure it’s installed cleanly and functions correctly.

Where should these alarms be located in the home?

Fire alarms should be installed in each bedroom, outside sleeping areas, and on every level of your home. CO detectors are typically placed near sleeping areas and in rooms with fuel-burning appliances. We review your layout to ensure full coverage and code compliance. Placement matters—and our team handles it with care and precision.
