As summer fades, many of us reminisce about the delightful moments spent on our decks, basking in the sun, hosting barbecues, and cherishing time with loved ones under the stars. 

However, before we know it, the chill of winter will set in, bringing harsh weather conditions that can wreak havoc on our favorite outdoor spaces. If you want to ensure that your deck remains a haven of relaxation and entertainment for the years to come, taking proactive steps to protect it is essential, especially in states like Idaho, where the weather can change rapidly. 

At Blue Sky Decks, we know that one crucial aspect of deck maintenance is knowing when to seal it, so let’s explore some considerations to help you make an informed decision.


  • Assess the Age of Your Deck. The age of your deck plays a significant role in determining whether it’s time to apply a fresh coat of sealant. If your deck is relatively new and you previously applied a sealant, it might still be in a good condition that can withstand winter’s challenges. However, if it has been several years since the last sealant application, it’s likely time for a reseal. Generally, decks should be sealed every one to three years to maintain their protective barrier against the elements.


  • Inspect for Visible Damage. Before making a decision, perform a thorough inspection of your deck. Look for signs of wear and tear, such as cracking, splintering, or wood warping. If you notice any of these issues, addressing them before sealing the deck is crucial. Ignoring existing damage and applying sealant on top can lock in moisture and exacerbate the problem, leading to more extensive repairs down the line.


  • Conduct a Water Beading Test. The water beading test is one simple test to determine if your deck needs sealing. Sprinkle a few drops of water on the deck’s surface and observe how it behaves. If the water beads up and forms droplets on the wood, the previous sealant is still effective, and you may not need immediate resealing. However, if the water is quickly absorbed into the wood, it’s time to add a fresh protective layer.


  • Check the Color of the Wood. The color of the wood can also indicate whether your deck requires sealing. If the wood has faded significantly and lost its natural luster, it’s a sign that the UV protection offered by the previous sealant has diminished. Faded wood is more susceptible to sun exposure and moisture damage, making it crucial to reseal before winter arrives.


  • Consider Local Weather Conditions. In Idaho, the weather can be unpredictable, with sudden changes in temperature, moisture, and snowfall during winter. Consider your area’s specific climate when deciding whether to seal your deck. If you expect harsh winter conditions, sealing can provide an added layer of protection against moisture and prevent water from seeping into the wood, which can cause rot and decay.


As summer winds down and the cold winds of winter draw near, protecting your deck should be a top priority. Sealing your deck not only safeguards it from the harsh winter elements but also ensures that you’ll be able to create more cherished memories with family and friends on your outdoor refuge in the years to come. 

So, don’t delay—prepare your deck now and rest easy knowing it will be ready to welcome you for another fantastic summer next year. For more information, please visit our website at Blue Sky Decks, or contact us today!
