How often do I need to stain my deck in Missouri?

Generally, wood decks need to be re-stained every two to three years, but this timeline may vary. The type of wood, the quality of the stain, and environmental conditions may affect longevity.

Missouri’s climate can have a significant impact on a wood deck due to its varied weather conditions throughout the year. In Missouri, the following climate factors may affect how long you can go between stain for your wood deck:

  1. Hot and cold — Temperature fluctuations are hard on your wood deck. Harsh conditions in Missouri summers and winters may significantly impact your deck. Temperature changes cause the wood to expand and contract which can lead to warping, cracking, and splitting.
  2. High humidity — Missouri’s sticky, humid summers can lead to moisture absorption and cause the wood to swell. This swelling increases the risk of mold, mildew, and rot, especially if the deck is not properly sealed with a proper stain.
  3. Heavy precipitation — Missouri’s yearly rainfall may lead to water damage if the deck is not well-protected. You may see your wood weaken and decay due to prolonged exposure to moisture.
  4. Snow and ice — Accumulation of snow and ice on the deck during the winter adds weight and moisture. Plus, cycles of freezing and thawing may exacerbate cracking and cause the wood to split.
  5. UV radiation from the sun — The sun’s UV rays can cause wood to fade and degrade, especially during the hot summer months. This can lead to a loss of color and strength in the wood fibers.
  6. Wind across Missouri — Blowing debris from strong winds can cause physical damage to the deck, such as scratches and dents. Wind may also drive rain and snow into crevices, which increases moisture penetration.
  7. Pollen and debris — As the seasons change, Missouri is known for increased pollen count and falling leaves. When these elements accumulate on the deck, they can promote mold and mildew growth if not regularly cleaned.

To mitigate these effects, regular maintenance is crucial. This includes:

  • Regularly applying a high-quality sealant and stain to protect the wood from moisture and UV damage.
  • Keeping the deck clean of debris, mold, and mildew to prevent decay.
  • Regularly inspecting the deck for signs of damage, such as cracks, splits, or rot, and addressing any issues promptly.
  • Ensuring proper drainage to prevent water from pooling on the deck surface.

By taking these steps, you can help ensure that your wood deck remains in good condition despite Missouri’s challenging climate.
