Choosing the Right Decking Material for Naperville's Climate

Illinois has a challenging climate, with hot, humid summers (85-95°F) and harsh winters (-10 to 20°F). Naperville experiences its fair share of both, along with significant snowfall. When choosing decking materials, consider the following:

• Pressure-treated wood: This is the most affordable option, but it requires regular maintenance to prevent rot and insect damage.
• Cedar: Cedar is naturally resistant to rot and insects, but it's more expensive than pressure-treated wood. It also requires regular sealing to maintain its appearance.
• Composite decking: Composite decking is a low-maintenance option that's resistant to rot, insects, and fading. It's more expensive than wood, but it can last for decades with minimal upkeep.
• Trex: Trex is a popular brand of composite decking known for its durability and wide range of colors and styles. It's one of the most expensive options, but it's a good choice if you want a long-lasting, low-maintenance deck.
