Frequently Asked Questions

Frequently Asked Questions

How much does it cost to build a deck per square foot?

Material costs for a deck range from $8 to $25 per square foot depending on the material. Pressure-treated wood is $8-12, composite is $15-25, and hardwood like Ipe is $20-35. Add $15-25 per square foot for professional labor.

Is a composite deck worth the extra cost?

Composite decking costs 2 to 3 times more than pressure-treated wood upfront but requires virtually no maintenance. Over 20 years, the total cost of ownership is often similar or lower than wood when you factor in staining, sealing, and board replacement.
