What Happens If You Don't Stain Your Wood Deck?

Will your deck fall apart, or will it just fade naturally? Here’s what Idaho and Nevada homeowners need to know.

Every year, homeowners around Boise and Elko ask us the same question: “Is it necessary to stain my wood deck?” Or even more directly: “What happens if I don’t?”

When it comes down to it, skipping deck staining isn’t just a cosmetic issue. Unprotected wood weathers faster, weakens structurally, and invites mold, pests, and costly repairs. 

In this article, we’ll break down what actually happens when you don’t stain your wood deck, how long you can go without doing it, and when hiring a pro might be your smartest option.

1. What Happens to a Wood Deck Left Unstained in the Harsh Weather?

Unstained decks absorb every bit of moisture and punishment from the elements. Boise and Elko weather conditions are no joke. Harsh sun in the summer, snow and ice in the winter, and big swings in spring and fall all contribute to premature aging.

Without stain, your wood deck is vulnerable to:

• Splintering and warping from sun exposure
• Fading and discoloration
• Moisture absorption, which leads to rot and mildew
• Freezing and thawing cycles that break down the fibers

Even a single Idaho or Nevada winter can leave a noticeable impact on unstained wood. 

2. Why Outdoor Deck Staining Protects Against Moisture and Rot

Moisture is the #1 reason outdoor wood decks deteriorate, and stain is the defense. Stain acts as a moisture barrier. It penetrates wood pores and seals them, helping prevent:

• Mold and mildew growth
• Wood rot from persistent dampness
• Pest infestations, including termites and carpenter ants

Think of outdoor deck staining like putting a raincoat on your deck. It might not seem urgent now, but come rainy season or snow melt, it matters. 

3. How Sun and Time Fade an Unstained Wood Deck

Untreated wood turns a worn, weathered gray that’s tough to reverse.

Sunlight breaks down wood fibers over time. This causes:

• Faded, uneven coloring
• A "tired" appearance, even if structurally sound
• Less curb appeal and lower resale value

Staining your deck lets you control the color. You can go for natural, rich, bold, or even solid shades that look like paint but protect like a stain.

4. Why DIY Wood Deck Staining is Harder Than It Looks

It takes some serious prep work if you want to stain your outdoor deck and have it last. Before staining, a professional team will:

• Power wash and clean the surface with a specialized cleaning & brightening solution
• Prep the surfaces for a new stain by scraping and sanding to remove the failed stain

Then, depending on the type of stain, it may need: 

• Multiple coats
• Brush, roller, or sprayer application
• Specific timing to avoid weather interference

If you skip steps or use the wrong tools, the stain can peel, wear out quickly, or fail to protect altogether. 

5. How Often Should You Re-Stain a Home Deck? 

Even the best stain wears down, so maintenance is key. Most home decks need to be re-stained every 2–4 years, depending on:

• How much sun and moisture exposure it gets
• Whether it's covered or not
• The type of stain used (semi-transparent vs. solid)

Maintaining your deck with regular staining helps preserve both appearance and durability, ultimately saving money in the long term. 

So… Should You Stain Your Deck or Let It Go?

If you’re hoping to preserve the look, strength, and safety of your deck for years to come, staining isn’t optional. It’s essential.
