Reviews from Madison Homeowners

Why "Testing Fine" Doesn't Mean a Smoke Detector Is Working
The test button only checks the horn and power — not the actual sensor. Sensors degrade over time. Replace units after 10 years regardless of test results.
We install modern dual-technology (ionization + photoelectric) combination units by default for maximum protection.
