As a home inspector, one common issues that we encounter during your inspections is yellowed smoke detectors. The discoloration can be a concern for homeowners and buyers, as it can indicate various issues. In this blog, we'll explore the reasons why smoke detectors turn yellow, what it means, and what homeowners can do about it.
What Does Yellowing Smoke Detector Mean?
While yellowing of a smoke detector may not impact the performance of the device, it's important to take note of it. A yellowed smoke detector may be an indication of aging or other issues, and it's important to investigate further to ensure that it's working correctly. In addition, if the yellowing is due to smoking, it may be a sign of poor indoor air quality.
What Should Homeowners Do?
If you notice that your smoke detector has turned yellow, the first step is to check the age of the device. If it's over ten years old, it's time to replace it, regardless of whether it's still working correctly or not. Homeowners should also clean the detector regularly to remove any smoke or other residues that may cause yellowing.
If the yellowing is due to exposure to UV light or chemicals, homeowners should try to reduce the exposure. For example, they can move the detector to a different location or use curtains or blinds to block out direct sunlight. If the yellowing is due to smoking, it's important to stop smoking indoors and improve the home's ventilation to ensure that the indoor air quality is healthy.
In conclusion, yellowing of smoke detectors is a common issue that homeowners may encounter. While it may not affect the performance of the device, it's important to investigate further to ensure that the detector is working correctly. If you're a homeowner, be sure to take steps to prevent yellowing, such as regular cleaning and reducing exposure to UV light or chemicals.
