Choosing the right decking material is one of the most important decisions in your outdoor project. Pittsburgh's four-season climate with hot, humid summers and freezing, snowy winters puts unique demands on decking materials. Here's how composite and wood compare.
Wood Decking: The Classic Choice
**Pressure-Treated Pine** is the most affordable option at $15-$25 per square foot installed. It's strong, readily available, and takes stain well. However, it requires annual maintenance (staining/sealing) and is susceptible to warping, splitting, and insect damage over time.
**Cedar and Redwood** offer natural beauty and rot resistance at $25-$40 per square foot installed. They require less maintenance than pine but still need periodic sealing. Their natural oils resist insects, but Pittsburgh's freeze-thaw cycles can cause cracking.
**Ipe and Tropical Hardwoods** are the premium wood option at $40-$60 per square foot. They're incredibly durable and beautiful but extremely hard (requiring pre-drilling for every fastener) and expensive.
Composite Decking: The Modern Alternative
**Standard Composite** (brands like Trex Select, TimberTech) costs $30-$45 per square foot installed. Made from a blend of wood fibers and recycled plastic, these products resist rot, insects, and fading. They require minimal maintenance beyond occasional cleaning.
**Premium Composite and PVC** (Trex Transcend, TimberTech Azek) costs $45-$65 per square foot installed. These offer the most realistic wood appearance, superior scratch resistance, and 25-50 year warranties.
Pittsburgh Climate Considerations
Freeze-thaw cycles: Composite decking handles Pittsburgh's temperature swings better than wood because it doesn't absorb moisture that expands when frozen.
Humidity: Our summer humidity causes wood to swell and contract. Composite remains dimensionally stable.
Snow and Ice: Composite surfaces can be shoveled without damage. Wood decks risk gouging from metal shovels.
Sun Exposure: Early composite products were prone to fading. Modern premium composites have UV-resistant caps that maintain color for decades.
Our Recommendation
For most Pittsburgh homeowners, we recommend **premium composite decking**. While the upfront cost is 20-40% higher than pressure-treated wood, the total cost of ownership over 20 years is actually lower when you factor in annual staining, sealing, and board replacement costs for wood.
If you love the authentic feel of real wood and don't mind annual maintenance, **cedar** is an excellent middle-ground option.
