How to prepare your deck for winter in Danville, KY comes down to five things: a real cleaning, a close inspection for rot, one last seal if it’s due, clearing furniture and rugs, and a plan for snow removal that won’t scratch the surface.
What Should I Do to My Deck Before Winter?
Clean it thoroughly, check every board and post for soft or rotting wood, seal it if it’s due, and clear off furniture, rugs, and planters so moisture can’t get trapped underneath them.
Clean Before the First Freeze
Sweep and blow off leaves and debris, especially between boards where they trap moisture. For wood decks, a proper wash with a deck cleaner (never straight chlorine bleach, which damages the wood fibers) clears mold, mildew, and algae before it sets in for winter. Composite decking generally just needs soap, water, and a soft brush.
Inspect for Rot and Loose Hardware
Press a screwdriver into posts, joists, and any spot that looks discolored or soft — wood that gives easily is starting to rot. Check railings and stair connections for movement, and tighten or replace any loose screws and fasteners now, before ice makes the deck harder to safely work on.
Seal Wood Decks If They’re Due
A water-resistant sealant or stain keeps wood from soaking up moisture that expands and cracks the boards when temperatures drop below freezing — a real risk in a Central Kentucky winter. Composite decking doesn’t need sealing, but it still benefits from the same fall cleaning.
Clear Furniture and Plan for Snow
Move furniture, rugs, grills, and planters into storage — anything left sitting on the boards all winter traps moisture underneath and can leave marks or accelerate rot. When snow does fall, clear it with a plastic shovel or soft-bristle broom rather than a metal-edged shovel, which can gouge both wood and composite surfaces, and skip rock salt on composite decking since some formulations can affect the finish.
A fall inspection is also the best time to catch problems worth fixing before they get worse over the winter — loose railings, soft boards, or a stain job that’s past due typically run $150–$600 to address, labeled as typical, depending on scope; larger repairs get a free on-site estimate. For material-specific care, Trex’s official care and cleaning guide covers composite decking in more detail.
Common Questions
Does composite decking need to be sealed before winter?
No. Composite decking doesn’t absorb water the way wood does, so it doesn’t need sealing — a fall cleaning is still worthwhile, but skip the sealant.
Is it OK to use rock salt on a deck?
On wood, sparingly; on composite, check the manufacturer’s guidance first, since some ice-melt formulations can affect certain composite finishes. A plastic shovel and sand are the safer default for either material.
How do I know if deck rot is bad enough to need repair now?
If a screwdriver sinks into a post, joist, or board with light pressure, that section has active rot and is worth addressing before winter rather than waiting until spring.
