Is It Time to Replace Your Smoke Detectors?

Not sure if your smoke alarms need to be serviced or replaced? Smoke detectors can become unreliable as they age, and many homeowners don't realize their alarms are outdated until they begin chirping, causing false alarms, or stop working properly.

Smoke Detector Pro provides professional smoke detector inspection, replacement, and installation throughout St. Charles County, St. Louis County, and surrounding Missouri communities. Our firefighter-owned team can evaluate your existing alarms, identify outdated or improperly placed devices, and recommend the right solution for your home.

Signs Your Smoke Detectors May Need Service or Replacement

  • Smoke alarms are approaching or over 10 years old

  • Smoke detectors are chirping even after battery replacement

  • Alarms frequently trigger false alarms

  • Smoke alarms are yellowed, damaged, or outdated

  • Hardwired smoke detectors are no longer communicating properly

How Often do Smoke Alarms need to be replaced?

Most smoke detectors should be replaced every 10 years because the internal sensors lose sensitivity over time. Replacing expired smoke alarms helps ensure your home remains properly protected from fire.

How to stop my smoke alarm from chirping?

A chirping smoke detector usually means something needs attention—it doesn't always mean there's smoke or an emergency. The most common causes include a low battery, a backup battery that needs replacing, dust inside the alarm, improper installation, or an expired smoke detector. Most smoke alarms should be replaced every 10 years, even if they still appear to be working.
