Fall Outdoor Furniture & Fixture Winterization: Protect Your Investment

Why winterizing outdoor items matters

The average American household has $2,000–$5,000 worth of outdoor furniture, grills, planters, and fixtures on their patio or deck. Leaving these items exposed to freeze-thaw cycles, snow load, and prolonged moisture cuts their lifespan by 50–70%. A teak dining set that should last 25 years will crack and gray in 5 if left out unprotected. Aluminum frames corrode at joints where water pools. Cushion fabric develops mildew that no amount of cleaning fully removes. Spending 2–3 hours on fall prep (or $200–$400 for a handyman to do it) protects thousands of dollars in assets and saves you from buying replacements every few years.

Material-specific care guide

• Teak and hardwood: Clean with a teak-specific cleaner ($10–$15) and soft brush — never pressure wash, which opens the grain and accelerates cracking. Apply teak oil or sealer ($15–$25) only if you want to maintain the golden color; otherwise let it weather to silver-gray naturally. Store in a dry location or use breathable covers (not plastic tarps, which trap moisture and cause mold).
• Wrought iron: Inspect for rust spots — sand with 220-grit, prime with a rust-inhibiting primer, and touch up with matching spray paint. Apply a thin coat of paste wax (car wax works) to all metal surfaces for a moisture barrier. Store indoors or cover — iron left in snow will develop rust under the paint by spring.
• Aluminum: Wash with mild soap and water. Check joints and feet for white powdery oxidation — sand lightly and apply automotive wax. Aluminum handles freeze-thaw well but salt spray (coastal or road salt) pits the surface quickly. Stack and cover or store in a garage.
• Wicker and rattan (natural): Must be stored indoors — no exceptions. Moisture swells the fibers, freezing cracks them, and one winter can destroy a set. Clean with a vacuum brush attachment, wipe with a damp cloth, and let dry completely before storage.
• Resin/plastic (HDPE, polypropylene): The most winter-tolerant material. Clean with soap and water, stack for space savings, and cover. Even plastic gets brittle in extreme cold, so avoid moving or stacking during freezing temps.
• Cushions and fabric: Wash removable covers per label instructions. Dry completely — any residual moisture becomes mildew by spring. Store in a dry indoor space (basement, garage closet) inside breathable bags, not plastic bins. If covers aren't removable, use furniture covers rated for your climate zone.

Grills and cooking stations

• Burn off residue on high for 15 minutes, then brush grates clean
• Disconnect and store propane tanks upright in a ventilated area (never indoors or in the garage)
• For natural gas grills, turn off the gas valve at the line and cover the connection point
• Clean grease traps and drip pans completely — old grease attracts rodents
• Apply a thin layer of cooking oil to cast iron grates to prevent rust
• Cover with a fitted grill cover — universal covers that are too loose flap in wind and let moisture in

Outdoor lighting and electrical

• Remove and store solar path lights indoors — cold temperatures permanently damage lithium batteries
• Coil and store string lights to prevent wire fatigue from wind whipping
• Check outdoor outlet covers for cracks — replace any that aren't weathertight ($5–$15 each)
• If you have landscape lighting on a transformer, drain the lines and shut off the transformer

When to call a professional

A handyman ($50–$80/hour) can handle full-deck winterization: moving heavy furniture, pressure-washing the deck surface, applying deck sealant, and covering or tarping large items. If you discover rot on your deck boards or railing posts during prep, call a carpenter — rotted structural members need replacement before winter snow adds weight. Cost for a deck winterization service visit: $200–$400 for a typical 200–400 sq ft deck. If you need furniture stored but lack space, some moving companies offer seasonal storage for $75–$150/month.
