Composite decking costs more upfront but saves thousands in maintenance. A pressure-treated deck needs $300–$600 in staining every 2–3 years — over 20 years, that's $2,000–$6,000 in maintenance alone. Composite needs nothing but occasional cleaning.
The cost of deck depends on several interconnected factors that can shift the final number significantly in either direction. Material quality is typically the largest variable — the gap between standard and premium options can double or triple the total project cost. Labor rates vary by region, with major metros running 30–50% higher than rural areas for identical work.
Project scope is the other major cost driver. What seems like a simple project can escalate quickly once walls are opened or existing conditions are revealed. This is why experienced contractors build contingency into their estimates, and why homeowners should too. The most common budget-breaker is changing the scope mid-project, which resets timelines and pricing.
