What Increases Porch Column Replacement Cost
- Load-bearing role: structural columns require temporary shoring
- Rot or moisture damage: base or footing repairs add labor
- Roof or beam sag: requires correction during replacement
- Material upgrades: fiberglass or PVC cost more than wood
- Multiple columns: alignment and leveling increase scope
When Replacement Is Required vs When Repair Is Not Enough
Replacement is required if:
- The column is rotted, split, or structurally compromised
- The porch roof or beam is sagging
- Temporary repairs have failed
Repair is usually not enough if:
- Damage extends through the column base
- The column supports roof or balcony loads
- Movement continues after cosmetic fixes
Rule: If the column carries structural load, replacement is safer than patching.
