Quick facts reported by NFPA and FEMA

  • Families on average have 3 minutes to escape from a house fire, before being overcome from smoke/heat. The sooner an alarm is triggered the better.
  • 3 out of 5 home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms. 
  • You have a 200% increase in getting hurt/killed with no working smoke alarms.
  • In fires in which the smoke alarms were present but did not operate, 50% of the smoke alarms had missing batteries or were defective.


Smoke detectors and CO alarms are made to last 10 years from date of manufacture, not beyond that. Most do not make it to a full 10 years. If you have the original smoke detectors in your home, chances are they are overdue for an upgrade!  Smoke detector response rate and sensitivity is severely diminished. Please keep your family safe and update / upgrade your alarms every 10years! Your smoke alarms are there to protect you!

****”Replace old smoke detectors in home. I asked Smoke Detector Medic to come out and try and diagnose the beeping noise that I thought I was hearing from my wired smoke dectector system. Randy was very accommodating with my schedule, and he and his wife showed up right on time to fix the problem. He figured out what the issue was and we got the beeping noise to stop. He thoroughly checked all my alarms and showed me that they were actually past their expiration date and really needed to be swapped out. He installed new smoke detectors and batteries so I am now reassured that the system is working correctly. Randy, a firefighter, is very knowledgeable and friendly, and I appreciated the work he did. I have vaulted ceilings and he brought out a ladder to reach the alarms. I was impressed by the service, and I will be asking him to come out every year and replace batteries and recheck the system. Highly recommend, especially if you have tall ceilings and hard to reach smoke detectors, or if you need someone with professional experience to check to make sure they are working correctly.”

****”My whole house alarm system would go off every three to four months, for no reason. This had been happening over the past four years with no smoke or fire detected any of the times. Each time I changed the batteries in all the detectors but the problem persisted. Randy came to the house the day after I called. He diagnosed the problem as a wiring harness issue in a downstairs bedroom. He had a new harness assembly installed the same day and the alarm has not gone off since it was done four months ago. Thanks Randy. No more midnight false alarms.”

***”Thank you so much for taking care of my family and I. Randy the owner took care of our situation fast and was very nice. I had several smoke alarms that were out of date and kept going off all through the night. My family likes our sleep and I will sleep much better knowing my home is safe!”

***”Smoke detector medic was professional, courteous and knowledgeable in what I needed. My home is now safe thanks to him. I will use him every year! My family went unprotected for a very long time and I needed the best. Besides updating and making my home safe, he educated me on our system and for the future. I would highly recommend him to anyone.”
