If you’re budgeting a composite deck building in Dallas, most projects run $8,238-$20,137, 8% below the $14,000 national average. What moves that number most is usually one thing: Deck Size. On its own it can swing the cost by $3,000 - $15,000+, so that’s the decision to slow down on before you sweat the smaller stuff.
