Cost & Estimates
Most residential deck waterproofing projects in the Portland metro area range from $8 to $25 per square foot depending on the system chosen, substrate condition, and accessibility. We provide free on-site estimates with detailed line-item pricing — no ballpark figures.
Timeline
Most residential projects take 3 to 7 working days from start to finish, depending on size, weather, and cure times between coats. We provide a detailed schedule with your estimate.
