Tips for Maintaining Your Cedar Deck

A cedar deck is more than just an outdoor surface — it’s an extension of your home. With its natural warmth, rich color, and durability, cedar is a favorite choice for Northwest backyards. But like all wood, it needs a little care to keep it looking its best. Here are a few simple tips to extend the life and beauty of your cedar deck.

1. Keep It Clean

Sweep away leaves and debris regularly. Organic matter holds moisture, which can encourage mildew and discoloration. A seasonal rinse with a garden hose (or gentle pressure wash on a low setting) helps prevent buildup.

2. Wash and Refresh Annually

Once a year, give your deck a deeper clean with a wood-friendly deck wash. This removes dirt, mildew, and graying caused by sun exposure. Be sure to follow up with a thorough rinse.

3. Protect with a Sealant

Cedar naturally resists decay, but sealing makes a big difference in keeping water out and preserving its rich color. Apply a high-quality, breathable wood sealer every 1–2 years. Transparent or semi-transparent stains allow the natural grain to shine through while adding UV protection.

4. Watch for Trouble Spots

Inspect your deck each season for loose boards, popped nails, or areas of standing water. Catching small issues early prevents bigger repairs down the road.

5. Let It Breathe

Trim back nearby shrubs and plants so air can circulate. Good airflow helps the wood dry after rain, reducing the chance of rot or mildew.

Pro Tip: Schedule your cleaning and sealing in late spring or early summer, once the weather warms up but before the heavy use of the season begins.

With just a little attention, your cedar deck will stay strong, safe, and beautiful for years to come — a perfect place to relax, entertain, and enjoy the outdoors.
