The system is more than boards
Posts or piles, horizontal members, sheathing, fasteners, anchors and filters must work together. A sound-looking face can conceal deterioration at the mudline, fasteners or embedded portions.
What homeowners can observe
- Soft, split or missing members
- Fastener staining, looseness or section loss
- Holes or galleries that may indicate organism activity
- Bulging, loss of backfill or separated boards
- Decay concentrated where wet and dry cycles alternate
Repair boundaries
Individual boards or connections may be replaceable when primary supports and anchors remain dependable. Widespread deterioration, inaccessible structural members or continuing soil loss can make piecemeal repairs less economical.
