What is the Average Cost of Deck Installation?

Table of Contents

When it comes to enhancing your outdoor living space, the question that often looms large is, What’s the average cost of deck installation? It’s a common inquiry, driven by the desire to budget effectively and make informed decisions about home improvement projects.

However, understanding the average cost of deck installation isn’t as simple as quoting a fixed dollar amount per square foot. In this comprehensive guide, we’ll unravel the intricacies of the average cost of deck installation, exploring the multitude of factors that contribute to its variability.

Why Deck Cost Varies

The average cost of a deck installation is a complex matter. Reputable deck builders won’t toss out a quick estimate because the price depends on numerous variables.

These variables include the type of materials, deck height, whether it’s covered, the number of steps, and even the topography of your backyard. For instance, if your house is perched on a slope, the deck might require specialty equipment and fall protection measures, increasing the overall cost.

Deck Cost Estimate

To illustrate the wide range of possibilities, consider this: we’ve built simple wood decks for as low as $20 per square foot. These were modest 10×10 structures barely a foot off the ground. On the other end of the spectrum, we’ve crafted elaborate decks at $120 per square foot.

These showstoppers featured stone-wrapped columns, integrated lighting, ceiling fans, and intricate underdecking with cedar inlays. The message here is clear: the average cost of deck installation depends on your project’s complexity and your design aspirations.

Material and Installation Costs

Breaking down the costs further, you’ll find that the installation alone typically ranges from $10 to $20 per square foot. However, this figure doesn’t include materials. Materials can add a significant layer of cost variability.

High-grade wood or composite materials can easily push the per-square-foot material cost into the $20 to $40 range. So, when estimating the average cost of a deck installation, you must factor in both material and installation expenses.

Risks of Cheap Quotes

While it’s tempting to go for the lowest quote, it’s crucial to understand the potential risks associated with cheap deck installation offers. Some contractors might offer astonishingly low prices, but these can come with hidden costs. Here are a few risks:

1. Lack of Licensing and Insurance

Some cut-rate contractors may not have the necessary licenses or insurance. This puts you at risk if accidents or damage occur during the project.

2. Poor Quality Materials

Cheap quotes often mean the use of subpar materials that won’t stand the test of time. You might end up with a deck that needs constant repairs.

3. Shoddy Workmanship

Contractors offering unrealistically low prices often cut corners to save money. This can result in a poorly constructed deck that’s unsafe and lacks the proper permits.

4. No Design or Drawings

A reputable contractor will provide you with detailed drawings and plans for your deck. Cheap alternatives might not offer any design documentation, leaving you in the dark about the final result.


In the world of deck installation, there’s no one-size-fits-all answer to the average cost. It depends on numerous factors, including your design preferences and choice of materials. While it might be tempting to opt for the cheapest quote, it’s essential to consider the associated risks. Avoid contractors who cut corners and lack proper licenses and insurance. Instead, seek out experienced professionals who prioritize quality and safety.
