Assessing the retained frame
Retained-frame redecking is appropriate only when the existing support system can serve the proposed result. The assessment includes foundations, posts, beams, joists, bracing and the house connection. Age alone does not answer whether these parts are suitable. Concealed damage may become clearer after boards are removed, so the estimate should explain how additional findings are handled. Record necessary structural corrections separately from the new walking surface, and identify when rebuilding is the more appropriate project instead.
