How long does a doorbell last?
A basic low-tech doorbell that consists of a bell button, a transformer, wiring, and a bell mechanism can be expect to last about 40 years. The bell button can be damaged or deteriorate over time from weather exposure, transformer eventually fails, or bell mechanism goes bad. Newer, hi-tech video doorbells have not been around long enough to determine an average life, but it will certainly be less. Also, see our blog posts Is a doorbell required by code for a house? and Can a doorbell transformer be installed inside an electric panel?
