Frequently asked questions.
What is the cheapest deck material?
Pressure-treated lumber is the most affordable option at $4–$6 per square foot. It's durable and can last 15–20 years with proper sealing and maintenance, though it requires regular staining or sealing.
Is composite decking worth the extra cost?
Composite decking costs more upfront but requires virtually no maintenance — no staining, sealing, or sanding. It typically lasts 25–30 years and resists rot, splintering, and insect damage, making it cost-effective over time.
Do I need a permit to build a deck?
Most municipalities require a building permit for decks, especially those over 30 inches above grade. Permit costs range from $50–$500 depending on your location and deck size. Always check local codes before starting.
How much does deck railing cost?
Railing typically costs $20–$35 per linear foot installed. Standard wood railing is on the lower end, while aluminum, glass, or cable railing systems can cost $40–$100 per linear foot.
