Protecting Homes Across St. Louis County

Smoke Detector Pro with a happy customer after Smoke Alarm installed and updated home

Every neighborhood has its own character, and every home has its own fire safety needs. Throughout St. Louis County you'll find historic brick homes, mid-century ranches, custom residences, villas, condominiums, and newer developments.

Residential Fire Safety Is More Than Replacing Smoke Alarms

Saint Louis County Home with updated smoke alarms

Many homeowners call us because one smoke alarm has started chirping.

During an appointment, we may evaluate:

  • The age of all smoke alarms

  • Carbon monoxide protection

  • Alarm placement

  • Interconnected operation

  • Bedroom and hallway coverage

  • Basement and garage protection

  • Five yellow stars in a horizontal row, with the last star partially obscured by a reflection.

    Randy was responsive from our 1st phone call. Showed up on time and was very efficient in installing the 3 detectors I had ordered...he even found one in the basement that I had forgotten about. Set up my phone with the Kidde app and explained everything thoroughly. He even educated me about the fire code and what I will probably have to do if I ever sell me house. Oh, and by the way, I thought his prices were very reasonable. I highly recommend "Smoke Detector Pro"!

  • Five orange star ratings in a row.

    Randy and his crew are true professionals. His response and expertise had helped me out of an almost impossible to solve issue with my smoke alarm system in our home. I highly recommend Randy and the whole team there, especially if you want intelligent answers to difficult questions. Keep up to good work!

  • Five yellow 5-star rating icons arranged in a row.

    Randy & Linzie did a fantastic job installing our smoke alarms. In & out in less than 45 minutes! Highly recommend!

    Dennis Broadbooks

  • Five gold stars aligned in a row with a glossy finish.

    Randy and his wife from Smoke Detector Pro has replaced and installed new smoke detectors in my previous house and again in my current house. They are friendly, reliable, efficient, punctual and decently priced. I highly recommend them for all your smoke detector needs.

  • Five yellow 5-star rating icons in a row.

    I had a smoke detector that went off on New Year’s Day! I didn’t know who to call and remembered that a friend had used Smoke Detector Pro and was very pleased. I certainly did not expect anyone to return my call on a holiday, but Randy did! He suggested several things to do and was able to solve the issue. Thank you, Randy! I’ve got your number and will gladly share with others!

  • Five yellow five-star rating icons on a black background.

    I knew my smoke alarms needed to be changed out since most were original from 2000 but kept putting it off. Then after replacing batteries in Sept 2 alarms started chirping in December and replacing the batteries again didn’t fix the issue. Randy was quick to reply and schedule my appointment. Explained everything clearly, tested the system , cleaned up and took all waste with him. Also installed carbon monoxide detectors which were lacking. Completely happy with the entire process. A+ service!

    Hedy Getz

  • Five orange five-pointed stars aligned horizontally.

    Updated and replaced our CO2, Smoke alarms as promised for the amount quoted. In and out in less than 30 minutes (including the cathedral ceiling). Came highly recommended and we're happy to pass it on.

    Don Ederer

  • Five orange five-star rating icons.

    I had a business acquaintance tell me he had a fire that took out part of his house. He said it originated in the dryer. I had Smoke Detector Pro update my smoke alarms and knew that they cleaned dryer vents. I thought I should do the safe thing so I called and they came out just when they said they would. I was surprised to see all the lint that came out of the vent. Apparently, just being diligent to clean the filter at the front of the dryer has not been adequate. I'm glad I got this job done by the Pros.

    Gary Chapell

  • Today we had our smoke alarms looked at in our “new to us” house! It was built 22 years ago and we bought it in Dec 2021. Little did we know that the smoke alarms in the whole house were the originally installed units. They were 22 years old. 😬 Randy was so helpful in pointing us in the right direction, and he installed all new units. Plus he answered all my worry questions about other “fire safety” needs. Thank you Randy for helping to keep our family safe!

    Mindy Early

  • Five gold star ratings aligned in a row, with a black background.

    Randy is a professional. I feel very comfortable knowing that a fireman installed all my smoke alarms. I also like that fact that he will remind me when they need to be replaced again. The service was excellent, and the price was good!
