What Does "10/4" Mean?
The 10/4 Standard is an annual home protection verification performed every October 4. It confirms the systems that protect your home are tested, working, and documented. Each year, key systems are checked across four areas—Water, Electric, Safety, and Temperature. The process verifies leak detection, shutoff valves, surge protection, backup power, smoke and carbon alerts, and freeze prevention.
It also includes a simple checklist homeowners can follow, guidance for professionals performing the verification, and clear documentation of what was tested.
The goal is simple: reduce risk, prevent avoidable damage, and make sure your home isn’t assumed safe—it’s verified.
W.E.S.T.: The Systems That Protect Your Home
Once a year, your home’s core protection systems—W.E.S.T. (Water, Electric, Safety, Temperature)—are tested, verified, and documented.
Water
Leak detection and automatic shutoff systems are tested and verified to help stop water damage early, protecting your home from costly repairs and hidden damage risks.
