Deck Maintenance Tips for Every Season

Deck Maintenance Tips for Every Season

After more than two decades in the deck-building business, I’ve seen beautiful outdoor spaces last for 30 years — and I’ve seen brand-new decks rot in less than five.
The difference? Maintenance.

Whether you have a wood, composite, or PVC deck, every material needs some level of care. Weather in Kentucky can be unpredictable — humid summers, rainy springs, and cold winters — and each season affects your deck differently.

Here’s my complete guide to deck maintenance throughout the year, built from years of real-world experience.

Spring: Inspection and Deep Cleaning

Spring is the season to wake your deck back up after winter. Start with a careful inspection before entertaining or grilling season begins.

1. Inspect for Damage

Walk the entire deck and check:

• Loose boards, popped nails, or wobbly railings
• Rotting or splintered areas (especially around posts and stairs)
• Rusted screws or nails
• Soft spots where water might have sat over the winter

If you spot any soft wood or movement in the railing, fix it right away. Moisture damage spreads quickly once the weather warms up.

2. Clean the Surface

A good deep clean removes mold, pollen, and grime.

• Sweep thoroughly to remove debris and leaves.
• Use a mild deck cleaner or a 1:4 vinegar-to-water mix for natural cleaning.
• For wood decks, use a soft-bristle brush — avoid pressure washing unless you know what you’re doing; too much pressure can damage the grain.
• For composite decks, use a manufacturer-approved cleaner to remove dirt and mildew.

Pro Tip: Clean your deck on a cloudy day — direct sun dries soap too fast and leaves residue.

3. Reseal if Needed

If you have a wood deck, spring is a great time to reseal or restain it. Test by sprinkling water:
If it soaks in rather than beads up, it’s time for a new coat of sealer.

Summer: Protect and Enjoy

Summer heat and humidity can take a toll on any deck — even low-maintenance materials.

1. Wash Off Dust and Pollen

A quick rinse once a month helps prevent buildup that can fade or stain surfaces. For composite and PVC decks, a garden hose or light soap wash is usually enough.

2. Check Furniture and Grills

Metal furniture can rust and leave marks. Add rubber pads to chair legs and avoid dragging heavy furniture.
Always place a grill mat under your barbecue to catch grease and sparks.

3. Shade and Sun Protection

UV rays fade both wood and composite over time. If your deck gets full sun, consider:

• Adding a pergola or canopy
• Using UV-resistant stains
• Rotating furniture to avoid discoloration patterns

4. Spot Maintenance

Keep a few matching boards and stain on hand. Fix small scratches or gouges right away instead of letting them grow into bigger repairs.

Fall: Prep for Rain and Cold

Fall is the perfect time to get ahead of moisture and leaf buildup — two of the biggest threats to deck longevity.

1. Clear Out Debris

Fallen leaves, twigs, and dirt trap moisture and promote mold.
Sweep regularly and clear out corners, steps, and between boards.

2. Clean Gutters and Downspouts

Overflowing gutters cause water to pool around your deck’s foundation — a leading cause of wood rot and mold underneath.

3. Check for Loose Fasteners

Seasonal expansion and contraction can loosen screws or nails. Tighten everything before winter sets in.

4. Seal the Wood

If you didn’t seal in spring, do it now. Late fall sealing helps prevent moisture absorption before freezing weather arrives.

Pro Tip: Use a clear, water-repellent sealer if you like your deck’s natural color — or a semi-transparent stain for UV protection.

Winter: Protect from Moisture and Ice

Even if you don’t spend much time outside in winter, this is when most hidden damage starts.

1. Keep It Clean

Brush snow off gently with a broom — never use metal shovels, which can gouge the surface.
For icy patches, use calcium chloride instead of rock salt. Salt crystals can stain or corrode fasteners.

2. Cover Furniture and Accessories

Moisture trapped under patio furniture or rugs can discolor or warp boards. Either store everything indoors or use breathable, waterproof covers.

3. Inspect After Freezes

After heavy snow or ice, look under the deck for sagging boards or frost heave around posts. Early detection saves major repair costs later.

General Deck Maintenance Tips (All Year)

Composite vs. Wood Maintenance

If you’re wondering whether composite decking is worth the investment — it depends on how much time you’re willing to spend maintaining your deck.

Wood decks need more care, but they have that classic charm many homeowners still love. Composite is ideal if you prefer a low-maintenance lifestyle and consistent appearance.

When to Call a Professional

Some maintenance tasks, like deep cleaning or re-sealing, can be done on your own.
But call a professional deck contractor if you notice:

• Soft, spongy boards
• Loose or unstable railings
• Cracked joists or sagging beams
• Fasteners pulling out
• Mold or rot spreading under the surface

A professional inspection every few years helps identify structural issues early and keeps your deck safe and sound.

Final Thoughts from a Deck Builder

After 25 years in the industry, I’ve learned that a little maintenance each season goes a long way. A clean, well-sealed deck not only looks great but also lasts decades longer than one left to weather on its own.

Your deck is more than just a structure — it’s part of your home, where memories are made every summer. Treat it with the same care you give the inside of your house, and it’ll reward you for years to come.
