I created Smoke Detector PRO LLC to help a growing community understand the importance of fire safety, while offering a low cost service. Fire and EMS respond to thousands of calls per year in St Charles County. In my years of experience I’ve seen many calls good and bad. Many times inexperience and lack of knowledge of how to properly maintain your household safety equipment was the culprit of several deadly incidents. Smoke detectors are the forefront of your families protection. Dryer vent cleaning is also needing to be checked annually. These especially need to be checked monthly for operation. Every 6 months or spring/fall the batteries should be changed.


Our growing community relies heavily on local Fire departments to change and maintain our smoke detectors and CO detectors. They do an excellent job! But there are some factors you have to take into account. Many times trucks are out of position when an emergency call comes out while changing a homeowners smoke detector batteries. This creates a delay in response, when minutes count, that can be the difference between life and death. Many times we are so busy we cannot respond to non emergent smoke alarm calls as we are busy with real emergency calls. This service I provide will help relieve this need.
