No reputable company would charge thousands of dollars for this type of service. If doing it yourself be sure not to replace your carbon monoxide detector with a smoke detector. We also offer Monitored smoke detectors combined with security systems.

I agree with replacing the smoke detectors every 10 years. But, why do you need smoke detectors with a permanently installed battery, if the detectors installed by the builder are powered by your house electricity? Why not just replace the alkaline batteries with 10 year lithium batteries? I understand that the code only requires the sealed, permanent type detectors for non-wired detector locations. It seems like an unnecessary expense, and not an upgrade to replace all of the detectors.
