A wooden deck is one of the most desirable features of a home, adding beauty, comfort, and functionality to your outdoor space. Whether you use it for relaxing evenings, family gatherings, or entertaining friends, your deck endures constant exposure to weather, which means proper maintenance is essential to extend its lifespan.
Here are some expert do’s and don’ts to help you keep your wooden deck in top condition.
1. Inspect Your Deck Regularly for Rot
Wood, even if treated, is vulnerable to rot when exposed to moisture over time.
- Pressure-treated lumber is more resistant to rot but still needs care.
- Redwood and cedar look beautiful but are more prone to deterioration if left untreated.
Check under deck boards, around fasteners, and at the ledger (where the deck connects to your home). If you find small patches of rot (coin-sized or smaller), you may be able to chisel it out. Larger areas should be repaired by a professional to prevent structural damage.
2. Clean Your Deck at Least Once a Year
Annual deep cleaning is key to maintaining a wooden deck.
- Start by sweeping away leaves and debris.
- Use a deck cleaner and a utility brush to remove mildew, dirt, and graying.
- Avoid chlorine bleach, which can damage wood fibers.
- Pressure washing can be effective but should be done carefully — ideally by a professional — to avoid splintering or gouging the wood.

3. Seal or Stain Your Deck
Applying a finish protects your deck from UV damage, moisture, and wear. Depending on the look and level of protection you want, you can choose:
- Clear sealer – Shows off the natural wood grain.
- Toner – Adds light color while highlighting grain and offering UV protection.
- Semi-transparent stain – Provides stronger color while still showing some grain.
- Solid stain/opaque finish – Hides the grain but offers maximum weather protection.
Most decks benefit from sealing or staining every 1–3 years, depending on weather conditions and usage.
