π Repair vs. Replace: When to Do Each
When to Repair Your Deck
Repair makes sense if:
- β Less than 25% of boards need replacement
- β Structural elements (joists, posts) are sound
- β Deck is under 15 years old
- β Damage is isolated to specific areas
- β Foundation and support posts solid
- β Cosmetic issues only (weathering, fading)
Average repair cost: $500-3,000
When to Replace Your Deck
Replace instead of repair if:
- β More than 50% of boards are rotted/damaged
- β Structural damage to joists, beams, or posts
- β Deck is 20+ years old
- β Extensive water damage or rot throughout
- β Deck is shifting, sagging, or separating from house
- β Repair costs exceed 50% of replacement cost
- β Want to upgrade size or materials
Average deck replacement cost: $6,000-15,000
π‘ Get Professional Assessment for Borderline Cases
If you're unsure whether to repair or replace:
- Hire a deck contractor for inspection ($100-300)
- They'll assess structural integrity
- Get quotes for both repair and replacement
- Compare 10-year costs (frequent repairs vs. new deck)
Example: If repairs cost $4,000 now but you'll need $2,000 more in 3 years, a $8,000 new deck might be smarter investment.
