Richmond County, NY
- Trim dead or overhanging branches before storm season.
- Check that gutters, siding and roof edges are fastened tight.
- Tie down or store outdoor furniture, grills and trampolines.
- Service the AC before the hot season and clear the outdoor unit of debris.
- Change the AC filter; a clogged filter cuts cooling.
- Plan a cool place to go if the power or AC fails.
- Know where the main water shutoff is and that it turns.
- Insulate pipes in unheated crawlspaces, garages and exterior walls.
- Have the heating system checked before winter.

- Fit storm shutters or pre-cut, labeled plywood panels and store the fasteners with them.
- Photograph every room and your roof before the season starts, for your insurance file.
- Know your evacuation zone and where you would go.
- Look up your FEMA flood zone, and remember that "minimal hazard" zones still flood.
- Raise or move valuables, the furnace and the water heater off a basement floor where you can.
- Test the sump pump and its backup before the wet season.
- Check your FEMA flood zone at your address; V and coastal A zones carry wave risk.
- Know your evacuation route and zone before a storm is named.
- Keep a flood-insurance policy in force; there is usually a 30-day wait.
- Pick the safe room: lowest floor, interior, no windows. Tell everyone in the house.
- Keep shoes, a flashlight and a helmet for each person there.
- Turn on wireless emergency alerts on every phone.
- Use surge protection for electronics; ask an electrician about a whole-home surge protector.

November6 tasks
- This monthPress 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.
- This monthCheck the date on the back of every smoke and CO alarm.
Smoke alarms wear out: NFPA advises replacing them 10 years after the manufacture date. CO alarms have their own end-of-life date printed on them.
How
Twist each alarm off its base and read the date. Replace any past its life; swap batteries in alarms that take them.
- This monthLook 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.
- This monthClean gutters and downspouts after the leaves are down.
Blocked gutters overflow at the foundation, rot fascia and, in cold climates, help ice dams form.
How
From a stable ladder (with a helper), scoop debris, then flush each downspout with a hose. Extensions should drop water 4 to 6 feet from the house.
- WatchLook in the attic with a flashlight after the first big storm of the season.
Stains on the roof deck, wet insulation or daylight around vents show leaks early, and droppings show pests.
How
Stay on the joists. Look around chimneys, vent pipes and valleys, the places most leaks start.
- WatchStock a power-outage kit: flashlights, batteries, water, a battery radio.
Winter storms bring multi-day outages.
How
Keep it in one bin. Add a phone power bank and a list of medicines that need power or refrigeration.
December2 tasks
- This monthPress 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.
- WatchDegrease the range-hood filter.
Grease-clogged hood filters stop pulling smoke and grease out of the kitchen and can feed a stovetop fire.
How
Pop the metal filter out and soak it in hot water with dish soap and baking soda, or run it through the dishwasher if the maker allows.
