The best material depends on your climate and budget. Composite decking (like Trex or TimberTech) is the most popular choice in New York due to low maintenance and 25-30 year lifespan. Pressure-treated wood is the most affordable at $24-$61 per sq ft installed. Cedar offers natural beauty but requires regular sealing.
A typical 200-400 sq ft deck takes 3-7 days to build once the permit is approved and materials are delivered. Permit approval in Buffalo can take 1-4 weeks depending on your local building department's workload. Plan for 4-8 weeks total from signing a contract to project completion.
Ask about their license and insurance coverage, who pulls the building permit, their warranty on labor and materials, a detailed written estimate, their timeline, and whether they use subcontractors. Also ask to see photos of recent deck projects in Buffalo and request at least 2-3 references.
