Deck sealing applies a protective layer to enhance appearance and resist stains, while waterproofing provides a barrier against water damage. For areas like Seattle, where rain is common, waterproofing is essential for long-term deck health.

Consider waterproofing your deck when you notice signs of wear like cracks, peeling, or visible moisture intrusion. In Seattle, regular maintenance and timely waterproofing can prevent costly repairs and extend the life of your deck.

In most cases, no permit is needed for deck waterproofing in Seattle, as it is considered maintenance. However, if structural work is involved, check with local authorities to ensure compliance with building regulations.
