Homeowner guide
A practical decision framework
Direct answer: Repair is reasonable only when the remaining structure is sound, accessible, and compatible with the new work. Replacement becomes more defensible when deterioration affects primary connections, framing is undersized or widely damaged, water entry is systemic, or reuse cannot be verified and warranted.
Key takeaways
1
Inspect the structure and connections below the decking.
2
Treat ledger and flashing defects as house-water risks.
3
Verify framing compatibility before installing composite decking.
4
Do not let cosmetic resurfacing hide unsafe guards or stairs.
Inspect from footings to rails
Check soil and footings, posts, beams, joists, hangers, ledger, flashing, lateral connections, decking, guards, stairs, landings, and movement.
Define reusable structure
A reuse plan should identify each retained component, condition standard, span, spacing, connection, treatment, and warranty. Hidden framing may require exploratory removal.
Compare project paths
Targeted repair, resurfacing, partial rebuilding, and full replacement have different permit, access, finish, code, and warranty implications.
Plan long-term performance
Choose materials with realistic heat, moisture, maintenance, fastening, ventilation, stain, scratch, and warranty expectations.

Frequently asked questions
Can composite decking go over old framing?
Sometimes, after joist spacing, plane, condition, ventilation, connections, and manufacturer requirements are verified.
Does a deck repair require a permit?
Requirements vary with structural scope, size, height, and location. Ask who determines and closes permit obligations.
How is hidden rot priced?
Use documented unit prices or a written change-order method for joists, beams, posts, ledgers, sheathing, and siding repairs.
When should a deck be closed immediately?
Visible collapse risk, separating ledger, severe movement, failed guards, unstable stairs, or extensive structural decay warrant restricted access and qualified evaluation.
