When homeowners in the Seattle area start planning a new deck, one of the first questions is often: What type of wood should I use? Many people choose based on appearance—what looks best with their home, backyard, or landscaping. While aesthetics are important, in the Pacific Northwest climate where rain, moss, and moisture are constant factors, the type of wood you choose will have a major impact on durability, maintenance, and long-term value.
Because many Seattle homeowners aren’t sure about the difference between hardwood and softwood decking, let’s break it down and compare the two.
What is Hardwood Decking?
Hardwood decking comes from slow-growing, broadleaf trees such as ipe, mahogany, or oak. These woods are denser and more complex in structure, which makes them durable and long-lasting but also more expensive. Processing hardwood takes more time, which contributes to the higher price tag.
In Seattle’s damp climate, hardwood decking performs well against rot, decay, and insects. It’s naturally resistant to warping even in areas with heavy rainfall.
What is Softwood Decking?
Softwood decking is typically sourced from fast-growing trees like cedar, pine, or spruce. In fact, Western Red Cedar is one of the most popular choices for Seattle decks because it’s readily available and blends beautifully with Northwest landscapes.
Softwood is easier to work with and much more affordable than hardwood. However, it does require proper treatment to resist fungal growth, moss buildup, and insect damage—common issues in wet Seattle neighborhoods like Bellevue, Kirkland, and Redmond.
Hardwood vs. Softwood: Pros and Cons
Advantages of Softwood Decking
- More affordable than hardwood (budget-friendly option)
- Sourced from faster-growing, eco-friendly trees
- Easy to work with and install
- If pressure-treated, can last many years
Disadvantages of Softwood Decking
- Fades more quickly in Seattle’s rainy, gray winters
- Lower density makes it weaker than hardwood
- Requires regular cleaning and sealing to prevent moss and mildew
Advantages of Hardwood Decking
- Extremely durable and long-lasting
- Beautiful, natural look that ages well over time
- Resistant to rot, warping, and splitting—ideal for wet Seattle weather
- Higher fire resistance compared to softwood
Disadvantages of Hardwood Decking
- More difficult to install due to density
- Higher cost because of sourcing and quality
- Needs regular maintenance (sealing, cleaning) to retain its appearance
Which Should You Choose for Your Seattle Deck?
So, is hardwood decking better than softwood? The answer depends on your lifestyle, budget, and how much maintenance you’re willing to take on. Both materials require upkeep—especially in Seattle, where rain and moss make decks slippery if not cared for.
