How Much Would a 20×20 Deck Cost in Naperville, IL?


Some homeowners might think of building a deck and maintaining it as an experience, when in reality it’s an investment. All outdoor patios or decks will increase the value of the property. The cost (investment) of building a new deck in Naperville is influenced by multiple factors including the season, materials, add-on services like built-in benches, and other features like lights, stairs, railings, etc. In this post we will give you a clear picture so you can plan your outdoor space investment accordingly.

What Affects the Cost of a 20×20 Deck in Naperville

1. Material Choice

The material you choose is one of the biggest factor that will impact the cost of your deck investment. Let’s into a few material options for clarity:

  • Pressure-Treated Wood: This is an affordable and reliable material that will cost somewhere around $2,500–$4,000 for a 20×20 deck.
  • Cedar or Redwood: Another material that offers natural beauty and is one of most durable ones on the market. The cost will range from $4,500–$8,000.
