If not properly treated and sealed decks can wear out.
We demolished this deck and replaced it with new boards and design as well. Since it was a duplex, both neighbors agreed to completing a similar design. We used cedar for the material. A bit more expensive than treated, but the product seems to be more durable. It still requires care annually.See the before and after pics.
The neighbors had problems with birds nesting underneath the deck. CD’s spinning on strings, screening, and windchimes did nothing to dissuade the birds from finding a new home, but the new screens and doors did the trick.
We gave them matching deck sizes that gave them more square footage than they originally had on their upper decks. If they wanted to coffee clatch from their own decks, they wouldn’t have to worry about falling over the edge to speak to each other.
