Security in Affton

Affton is an unincorporated community in south St. Louis County, known for its affordable, tightly-knit neighborhoods and older ranch-style and split-level homes built largely in the 1950s and 1960s. Many of these homes predate modern security systems, making professional wireless upgrades both practical and popular. Affton is served by the Lindbergh and Mehlville-Oakville fire districts and the St. Louis County Police. Philibert Security regularly retrofits older Affton homes with modern wireless sensor systems, preserving the original construction while delivering contemporary 24/7 monitoring.
