November home maintenance checklist for New Castle County, DE

Test smoke and CO detectors
Detectors are the one system in your house where "it looks fine" means nothing — the sensor inside degrades on its own schedule regardless of how clean the outside is.

Disconnect garden hoses before the first freeze
With around 92 freeze days a year in New Castle County, this is the highest-value ten minutes on your calendar.

Space heater rules, before the cold snap
A space heater is a 1,500-watt appliance — a full circuit's worth of load — that lives on the floor near fabric and gets moved around by whoever's cold.

Winter storm readiness
With ~92 freeze days a year in New Castle County, winter isn't a surprise — but the FIRST hard freeze each season is still the one that does the damage, because it finds whatever changed since last year: the hose left on, the crawlspace vent knocked open, the cabinet remodel that put a sink pipe against an exterior wall.
Scheduled ahead of New Castle County's average first frost (11/02).

Skip the AC cover (mostly)
Every fall the covers appear at the big-box stores, and every spring the service techs find what they did: coils sweated under vinyl all winter, rust where the moisture sat, and mouse nests in the wiring of the warmest sheltered box in the yard.
Scheduled ahead of New Castle County's average first frost (11/02).
$40–$80to hire out here
Clean gutters and check downspout flow
Gutters have one job: get roof water away from your foundation.
$120–$255to hire out here
Crawlspace vents — the seasonal switch
Crawlspace vents are one of building science's ongoing arguments, so here's the honest version for a vented crawlspace in a freeze climate: the vents exist to let summer moisture out, and in winter they mostly let freezing air in.

Head off ice dams before the snow flies

Crawlspace moisture check
Out of sight is exactly how crawlspace problems get expensive — nobody looks until a floor feels soft.
$100–$255to hire out here
Leaves — mow them, don't fight them
Here's the part the bag-every-leaf tradition gets wrong: your lawn doesn't need rescuing from leaves.
$155–$410to hire out here
Degrease the range hood filter
That metal mesh over your stove has one job: grab airborne grease before it gets into the fan, the duct, or back into your kitchen air.
$100–$255to hire out here
Oven and range clean-and-check (before the holidays)
The range is the appliance most likely to start a fire in your house, and the fuel is almost always accumulated grease — under the burners, in the drip trays, filmed on the oven walls, and soaked into whatever's been living in the drawer underneath.
$130–$255to hire out here
Winterize the mower and gas tools
Small engines don't die of work; they die of storage.
Scheduled ahead of New Castle County's average first frost (11/02).
