May maintenance for a hot-dry climate

Intense sun and heat, little rain, monsoon storms in some areas, and hard water.

5 tasks this month. The median typical first freeze across the region’s counties is Nov 9 and the last is Mar 26; your county can differ by weeks.

  1. This month
    Press the test button on every smoke and CO alarm.

    An alarm you have not heard in months may have a dead battery or sensor. NFPA recommends testing smoke alarms at least once a month.

    How

    Hold the test button until it sounds. Anything silent or chirping: replace the battery, or the whole alarm if it is past its date.

  2. This month
    Look under every sink and around toilets and the water heater for drips.

    Slow leaks rot cabinets and subfloors long before they show. Catching one early is a washer, not a floor.

    How

    Use a flashlight: feel supply lines and the shutoff valves, look for stains, warped cabinet floors or a toilet that rocks.

  3. Watch
    Switch ceiling fans to spin counterclockwise for summer.

    A fan blowing air down creates a wind-chill effect, so you can set the thermostat a little higher and stay comfortable. Fans cool people, not rooms: turn them off when you leave.

    How

    Stop the fan and flip the direction switch on the motor housing; you should feel a breeze standing under it.

  4. Watch
    Inspect the deck: loose boards, popped fasteners, wobbly railings, ledger flashing.

    A loose railing or a rotted ledger connection is how decks fail under load.

    How

    Push on every railing post, look underneath where the deck meets the house, and tighten or replace fasteners.

  5. Watch
    Check that soil and mulch slope away from the foundation.

    Water that pools against the foundation finds its way into basements and crawlspaces.

    How

    Look for low spots after a rain; build soil up so it falls about 6 inches over the first 10 feet where you can.
