May maintenance for a marine climate

Mild and wet: moisture, moss, gutters and ventilation matter more than extreme temperatures.

3 tasks this month. The median typical first freeze across the region’s counties is Nov 11 and the last is Mar 29; your county can differ by weeks.

    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.
