The Weekend Backyard Winterization Checklist (What Most Guides Skip)

Most winterization guides tell you to drain your hoses and cover your furniture. You already know that. What they skip is the stuff that actually causes expensive problems — the things that seem fine going into winter and are broken coming out of it.
The Things That Actually Fail
Outdoor faucet shutoffs are one of the most common winter failures, and they’re also one of the most preventable. The frost-free sillcock style faucet requires the shutoff valve to be fully open or fully closed — leaving it half-open allows water to sit in the valve body where it can freeze and crack. Before the first hard freeze, turn off the interior shutoff, open the outdoor faucet to drain the line, then leave it open slightly overnight to ensure any remaining water drains. A cracked sillcock is a $200+ repair; this takes three minutes.
Outdoor lighting timers and smart switches are another failure point. Outdoor-rated doesn’t mean freeze-proof. Devices with LCD displays, rechargeable batteries, or exposed circuit boards can be permanently damaged by sustained temperatures below 20°F. Pull timer units indoors before hard freezes. Smart outdoor outlets that are wired in can stay, but any battery-backup component should be removed.
Irrigation controllers — even “winterized” ones — often get their backflow preventer cracked because homeowners run the winterization blowout but forget to cap or insulate the backflow assembly above ground. This is the most-missed step in irrigation winterization. The blowout clears the lines, but the brass backflow preventer housing is still sitting exposed to air. Wrap it in foam pipe insulation and secure it with tape.
Furniture Covers Done Right
The biggest mistake with covers isn’t skipping them — it’s covering wet furniture or covering without ventilation. A non-breathable cover traps moisture against cushions and frames, creating exactly the mold conditions you’re trying to prevent.
The Classic Accessories Ravenna patio cover uses a breathable outer fabric with vented side panels — it blocks rain but lets moisture vapor escape. Form-fitting covers like this also resist wind, which matters because a cover that migrates off a sectional by January isn’t protecting anything.
For hard surfaces — concrete, pavers, composite decking — consider the timing of your first cover installation. Covering a deck immediately after a rain traps that moisture. Wait for 24 hours of dry weather, then cover. And if you have wood deck boards, check the surface with a moisture meter first; wood above 20% moisture content shouldn’t be sealed under a cover without ventilation gaps.
Propane and Gas Line Checks
If you have a propane grill or fire table, disconnect and store the tank in a shed or detached garage — never in an attached garage or basement. Before storing, check the regulator hose for cracks, especially near the connector fittings. Cold makes rubber hoses brittle, and a hose that was marginal in fall will be cracked by spring. Replacement hoses cost $15–30 and take five minutes to swap; a propane leak repair costs much more.
For built-in gas fire pits or outdoor kitchens with gas lines, install a cap on any exposed fitting before winter. A spider can build a nest in a gas orifice over winter and cause backfire issues when you light it in spring — it happens more than you’d think and is completely preventable with a $2 fitting cap.
The Storage Order That Matters
Most guides say “clean and store your cushions.” What they don’t tell you is the order. Clean first, then dry completely (48+ hours in low humidity), then store in a sealed bag with a desiccant packet inside. Storing even slightly damp cushions in a sealed plastic bag creates the perfect mold environment. The storage bag with desiccant style approach works well for cushions — the tight seal keeps pests out while the desiccant handles any residual moisture.
The other missed item: check all outdoor wooden structures — pergolas, trellises, raised beds — for cracks or splits before winter. Water gets into small cracks, freezes, and expands those cracks significantly. A 10-minute inspection and some exterior caulk in September prevents a structural repair in April. Our full backyard winterization guide covers the complete inspection sequence, and if you’re thinking about your outdoor rugs as part of this, the outdoor rug guide for fall is worth a read before storage.
One More Thing: Take Photos
Before you put anything away for winter, photograph it. Photograph how your irrigation system was plumbed, where your outdoor lighting ran, what your furniture layout looked like. In spring, you’ll be glad you did — especially if you’re troubleshooting a system that someone else (a spouse, a contractor) put away. It takes two minutes and has saved me at least one reinstallation headache every year.
