    Is it time to check your detectors?

    Smoke and carbon monoxide are both toxic and potentially fatal contaminants, and detectors provide an early warning when every second counts. Outdated, missing or faulty detectors put your home and family at risk. Here are the signs it's time to call an electrician.

    Your detector is chirping or false-alarming

    A defective unit, battery or wiring may sound false alarms or fail to activate as designed. A chirp that continues after a battery change, frequent false alarms or visible damage are all signs a detector needs service.

    Your detectors are past their lifespan

    Smoke detectors typically need replacing every 10 years. Carbon monoxide detector lifespans vary by manufacturer, so check the end-of-life date printed on your unit. Past that point, sensors can wear down and stop responding as they should.

    A detector doesn’t sound during a test

    A detector that fails a test can't be counted on in an emergency. Dead batteries, faulty sensors and outdated units are all common causes.

    Gas appliances, an attached garage or high ceilings

    Spaces with high ceilings, attached garages or gas appliances require strategic placement to ensure complete coverage. A custom installation plan covers your home fully without adding devices you don't need.

    You need to meet code before an inspection

    Smoke and carbon monoxide detectors are commonly required in building codes, and some local codes in the St. Louis area require inspections for new installations. We make sure our work meets them.

    You want interconnected or smart detectors

    Interconnected and smart detectors communicate across your entire home, and many can connect with existing monitoring or security platforms for centralized alerts.

    Reviews That Speak for Themselves
