Composite and PVC have mid-to-high initial costs but save on maintenance, whereas wood is less expensive initially but requires ongoing staining and repairs.

How Long Does Each Decking Material Last in Iowa’s Weather?

In Iowa’s demanding climate, lifespans are roughly:

  • Aluminum: 50+ years
  • Composite: 25–30 years
  • PVC: 25–30 years
  • Cedar: 15–20 years
  • Pressure-Treated Wood: 10–15 years

Materials with engineered cores or metal construction outperform wood in freeze-thaw and moisture resistance.

What Are the Maintenance Requirements for Different Decking Materials?

Composite and PVC need only periodic cleaning with soap and water. Aluminum benefits from an annual rinse to remove debris. Wood requires year-by-year inspection along with resealing or restaining every 1–3 years and occasional board replacement to prevent rot. Choosing low-maintenance options helps reduce labor and preserves deck beauty.

Maintenance and Lifespan of Decking Materials Studies show that regular cleaning and inspections can extend decking lifespan significantly. Composite and PVC generally offer lower maintenance compared to wood, which needs periodic sealing or staining.
