01 The situation
The challenge
The patio decks behind the townhomes had weathered gray, the boards had cupped, and the rim boards had split at the corners where they joined. Lifting boards showed why: the joists and rim boards were water-damaged at their ends, so new decking alone would have gone onto framing that was already failing.
The other quote the owner had in hand was a full replacement from new footings: dig out every concrete pier among the planting and the privacy walls, pour new ones, then build. That would have meant more cost, more disruption on each patio and longer time without a deck, for piers nobody had actually checked. The owner wanted to know first what was sound and what was not.
02 Execution
What we did
We checked the piers and post bases before deciding what to rebuild:
Lifted boards and probed the joists, rims and posts on every deck, and checked each concrete pier and post base for movement, level and corrosion
Removed the decking, joists and rim boards down to the post bases, keeping the concrete piers, the galvanized post bases and the privacy walls between units
Framed new joists and new rim boards on the existing supports, with the rim boards bolted together at the corners
Laid new wood decking on every deck and closed the permit with a final inspection on each building
03 Outcome
The result
Every patio deck now has new framing and new decking, set on piers that were checked rather than assumed. Keeping the piers and post bases removed the excavation and concrete work from the scope, and leaving the privacy walls standing meant each patio stayed private while its deck was rebuilt. The work closed with a permit and final inspection on file.

Before & After

Rim board on concrete piers
“The concrete piers were fine; the wood on top of them wasn't. They rebuilt the decks on what was already there, and our residents kept their privacy walls the whole time.”
