Constructing a deck in Washington State is not easy and presents opportunities. The Pacific Northwest weather with rainy, wet winters and warm, dry summers can play a significant role in deck construction. Whether you are in Seattle, Spokane, or somewhere in between, it’s essential that your deck be constructed correctly for safety and durability.
Here are five common decking mistakes to avoid during your build, specifically tailored to Washington State’s conditions.
- Choosing the Wrong Materials for the Pacific Northwest Climate
The differing climate of Washington means that differing materials will function differently in Washington’s rain and typically cold climatic conditions. One error often made by residents is forgetting how rain, moistness, and temperature fluctuations might affect their choices when it comes to using different materials.
**Composite Decking:** Composite decking materials are an ideal choice for the rainy weather of Washington. Composite materials are resistant to rot, mold, and moisture damage, making them ideal for areas where there is a lot of rainfall. Composite decking is also low maintenance, which is a big plus factor given the humidity of the region.
**Cedar Decking:** Cedar is a beautiful option for many homes in the Pacific Northwest, but it requires regular care, especially in areas with heavy rainfall. While cedar is naturally resistant to rot, it still needs periodic sealing and staining to protect it from moisture. Without proper maintenance, cedar can gray and become vulnerable to weather-related damage.
If you live in a particularly damp area, be sure to choose materials that can withstand prolonged exposure to rain without deteriorating quickly.
- Failing to Account for Proper Drainage and Moisture Control
Washington’s rainy season can indeed be lengthy, and some areas receive up to 150 days of rain. Water will build up around and under your deck and lead to problems such as wood rot, rusty fasteners, and mold infestation if it is not properly drained. This is one of the most significant mistakes homeowners commit.
To avoid these issues, consider the following steps:
- **Install Drainage Systems:** When building raised decks, it may be a good idea to install under-deck drainage systems to prevent water from accumulating and creating moisture problems below. A good drainage system, like a moisture-resistant membrane, is effective in preventing both the deck and the area underneath from getting water damage.
- **Ensure Proper Slope:** The ground beneath your deck should have a slight slope to direct water away from your home’s foundation. In the wet climate of Washington, water accumulation can weaken the deck’s foundation and lead to shifting over time.
Proper drainage is essential to prevent your deck from becoming a long-term liability due to the frequent rain and damp conditions in Washington State.
- Overlooking Local Building Codes and Regulations
When planning to build a deck, it may be tempting to rely on generic plans. However, it’s essential to consider that Washington State has specific building codes designed to ensure your deck is safe and secure. Ignoring these local regulations can lead to costly repairs, fines, or even the necessity of tearing down your deck entirely. It’s a risk that’s not worth taking.
Here are some important factors to keep in mind:
**Deck Height and Railings**: If your deck is more than 30 inches above the ground, it will likely require safety railings. Be sure to check the height requirements and railing specifications for your local area.
**Footings and Foundations**: Soil conditions in Washington can vary significantly. It’s crucial to adhere to the state’s foundation requirements for decks. In areas with soft or clay-heavy soil, you may need to install deeper or reinforced footings to ensure stability, particularly given the frequent rainfall and occasional snowmelt during winter.
To avoid penalties and ensure the safety of your deck, it is essential to work with a contractor who is familiar with local building codes and regulations.
- Neglecting the Impact of Moss and Algae Growth
Washington’s humid and rainy climate creates ideal conditions for moss, algae, and mildew to thrive on deck surfaces. While this may seem like a minor issue, it can lead to unsafe conditions and the deterioration of your deck over time.
**Regular Cleaning:** Decks in Washington State require regular cleaning to prevent the buildup of algae and moss. This is especially important for wood decks, which can absorb moisture and become breeding grounds for mold and mildew.
**Moss-Resistant Finishes:** Consider applying a moss-resistant treatment to your wood or composite decking. This treatment will help prevent the growth of moss and algae, particularly in shaded or damp areas of your deck. While composite decking generally resists moss growth more than wood, it is still important to clean it periodically.
Forgetting moss and algae growth can not only change the look of your deck but also make unsafe, slippery surfaces. To prevent these problems, be sure to clean and treat your deck on a regular basis.
- Underestimating the Need for Regular Maintenance
Even when you have low-maintenance items like composite decks, there has to be some maintenance regularly due to Washington state’s varied weather. Composite decks are less finicky than wood, but cleaning them occasionally has to be done to remove dirt, leaves, and other items that don’t belong on there. Cedar wood and wood decks require more in the Pacific Northwest. Remember, regular maintenance is the key to a long-standing and beautiful deck.
Here’s how to stay on top of maintenance:
**Wood Decks:** If you choose wood, specifically cedar, be sure to seal it every year or every other year to protect it from air moisture. Washington’s rainy winters will warp and swell wood; if not sealed, your deck will be open to the elements.
**Composite Decks:** Composite decks are easier to maintain than wood, but they also have to be washed every now and then with mild soap and water. Regular maintenance will loosen any dirt and grime, ultimately causing staining or discoloration.
By staying on top of maintenance, you can extend the life of your deck and ensure that it remains a beautiful and functional part of your home for years to come.
Building a deck in Washington State requires careful attention to detail, especially given the unique challenges posed by the region’s climate.
