The Ultimate Guide to Deck Maintenance: Seasonal Checklist

Your deck is more than just wood and nails—it’s the stage for summer barbecues, quiet morning coffees, and family celebrations. But without proper care, weather and wear can shorten its life. The good news? A little seasonal maintenance goes a long way toward keeping your deck strong, safe, and beautiful.

Here’s a seasonal deck maintenance checklist to guide you year-round:

Spring – Fresh Start

• Sweep away leaves, dirt, and debris.

• Power wash or scrub the surface to remove mold and mildew.

• Inspect for loose boards, nails, or railings.

Summer – Protect & Enjoy

• Apply a protective sealant or stain to guard against UV damage.

• Check for water pooling after rain (a sign of drainage issues).

• Tighten any bolts or screws after heavy use.

Fall – Prepare for Change

• Remove furniture and planters to prevent trapped moisture.

• Clear away fallen leaves that can stain and cause rot.

• Reapply sealant if needed before winter arrives.

Winter – Defend Against the Elements

• Regularly brush off snow to prevent buildup (avoid metal shovels).

• Keep the surface dry to reduce slipping hazards.

• Check railings and supports for weather-related stress.

By following this cycle, your deck can last decades instead of just years.

Built Tough Tip

Always use a high-quality water-repellent sealer. Moisture is your deck’s biggest enemy, and protecting it now will save you from costly repairs later.

Reflection

When was the last time you did a full deck check-up? A simple inspection today could prevent major damage tomorrow.
