The San Jose Homeowner's Maintenance Checklist (Month by Month)

A month-by-month upkeep plan tuned to San Jose's climate, catch problems before they cost you.

The cheapest home repair is the one you prevent. This checklist is tuned to San Jose, where high Silicon Valley home values and a taste for clean finishes shape the calendar.

Year-Round Home Checklist

  • Rinse salt off outdoor AC and metal fixtures.
  • Check window and door seals against moisture.
  • Service the AC once a year for reliability.
  • Watch for corrosion on exterior hardware and railings.

Year-round basics

  • Test smoke and CO detectors twice a year.
  • Change HVAC filters every 1-3 months.
  • Check under sinks and around the water heater for leaks.
  • Walk the exterior each season for cracks, gaps, and worn caulk.

When to call a pro

Roof, electrical panel, gas, and anything structural. A $115-$230 inspection is cheaper than the repair it prevents.
