Verify licenses and insurance

The best material depends on your climate and budget. Composite decking (like Trex or TimberTech) is the most popular choice in Michigan due to low maintenance and 25-30 year lifespan. Pressure-treated wood is the most affordable at $18-$45 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 Detroit 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 Detroit and request at least 2-3 references.
