How It Works
Deck remodeling costs depend heavily on the decking material chosen. Pressure-treated wood is the most affordable at $8/sqft for materials, while PVC is the most expensive at $28/sqft. Composite decking at $22/sqft offers the best balance of durability and appearance with minimal maintenance.
The Formula
Variables
- Decking Cost — Per sqft: pressure treated $8, cedar $14, composite $22, PVC $28
- Framing — Structural framing at $8/sqft (pressure-treated for all deck types)
- Railing — Per linear foot: $35 wood to $85 PVC, matching deck material
- Labor — Installation: $12-$18 per sqft depending on material complexity
- Footings — Concrete footings at ~$150 each, one per 64 sq ft of deck
Worked Example
For a 300 sq ft composite deck with 40 ft railing, 1 stair set, and demo: Decking $6,600 + Framing $2,400 + Railing $3,000 + Stairs $1,200 + Labor $4,800 + Demo $1,200 + Permits $500 + Footings $750. Total = $20,450 (~$68/sqft).
Practical Tips
- Composite decking costs more upfront but never needs staining, sealing, or sanding
- Pressure-treated wood requires annual sealing and staining to prevent rot and warping
- Hidden fastener systems cost more but give a cleaner look with no visible screws
- Plan for adequate joist spacing: 16 inches on center for most materials, 12 inches for diagonal patterns
- Add a slight slope (1/8 inch per foot) away from the house for proper water drainage
Frequently Asked Questions
How long does a deck last?
Pressure-treated wood lasts 10-15 years, cedar 15-20 years, composite 25-30 years, and PVC 30+ years with proper installation.
Do I need a permit to build a deck?
Yes, almost all municipalities require a permit for deck construction. Decks over 30 inches high typically require engineered drawings.
Is composite decking worth the extra cost?
Yes for most homeowners. The higher upfront cost is offset by zero maintenance costs over its 25-30 year lifespan. Wood decks need $200-$500 in annual maintenance.
Can I remodel just the decking and keep the frame?
Yes, if the existing framing is structurally sound. Have a professional inspect for rot, insect damage, and proper connections before resurfacing.
What is the best time of year to build a deck?
Late spring through early fall offers the best building conditions. Off-season (winter) may get you 10-15% discounts from contractors with lighter schedules.
