Factors like deck size, material type, labor, and additional features will influence the total cost. With thoughtful budgeting and the help of a professional, you can create a beautiful deck that adds value to your home and enhances your outdoor enjoyment.

Composite Decking Cost Factors

While the average 144-square-foot composite deck costs $5,200, the cost to build a deck varies greatly depending on the size, material, prep work, and labor fees. 

Project Size

Deck size plays a significant factor in the installation cost of your composite deck, with prices ranging from $25 to $54 per square foot. An 80-square-foot deck might cost as little as $2,000 to install, while a 400-square-foot deck can cost up to $20,000.

Materials

Material costs for composite decking can range from $4 to $15 per square foot, depending on the type of material. The choice of material significantly affects the overall cost of your deck.

Labor

Labor costs for composite decking installation range from $10 to $14 per square foot, and pros charge an average of $25 per square foot for any stairs. The primary professionals involved in deck installation include:

• Carpenters: Charge $35–$100 per hour; responsible for framing and construction

• Deck builders: Charge $15–$35 per square foot; specialize in deck installation

• Laborers: Assist with tasks at $10–$25 per hour

Labor costs may vary based on your region and current market rates.

Demolition and Prep

If you're replacing an old deck, remember to factor in the cost of tearing down and removing the existing structure, which runs from $5 to $15 per square foot. While tackling the demolition yourself can save money, it requires time and effort. 

Permits

A deck permit costs between $225 and $500, depending on where you live. Many areas require permits for deck construction to ensure safety standards are met. Working with a professional contractor can simplify this process—they'll handle the paperwork and make sure everything is up to code.

Additional Components

Keep in mind that the decking boards are just one part of the overall cost. You'll also need to budget for railings, substructures, posts, and hardware. Here’s how these costs break down.

Ongoing Maintenance

Composite decks are popular because they are low maintenance, especially compared to natural wood decks. Just sweep it and hose it down as needed. Otherwise, you won’t need to worry about composite deck maintenance costs, saving you time and money in the long run.

Does Composite Decking Increase Home Value?

Absolutely, installing a composite deck can significantly boost your home's value. Homeowners see a remarkable ROI of 82.9% on deck additions, with an average resale value of nearly $14,600. A composite deck doesn't just expand your living space; it also appeals to potential buyers seeking low-maintenance, durable outdoor areas.

Composite decks resist rot, fading, and warping, so future owners won't have to worry about costly repairs. By enhancing your home's functionality and curb appeal, a well-designed composite deck makes your property stand out and can even help it sell faster.

Budgeting for Composite Decking

Looking to build your dream deck without breaking the bank? Here are some smart strategies to help you save money without sacrificing quality:

• Stick to standard sizes: To reduce material and labor costs, opt for a standard deck size instead of custom dimensions.

• DIY demolition: If you're replacing an old deck, handling the demolition and disposal yourself can cut down on labor fees.

• Limit the extras: Keep your design simple by avoiding unnecessary add-ons like extra railings, elaborate stairs, or complex layouts.

• Shop around: Get quotes from at least three local deck builders to find the most competitive price.

• Choose the right timing: Schedule your installation during the off-season when contractors may offer reduced labor rates.

• Select budget-friendly materials: Pick cost-effective decking materials that still provide durability and low maintenance.

DIY vs. Hiring a Composite Decking Pro

Without the right skills, you might run into challenges like cutting boards to precise lengths, ensuring a level foundation, or navigating obstacles like trees and uneven terrain. Mistakes can be costly and may affect your deck's safety and longevity.

Hiring a professional composite deck builder ensures your deck is installed correctly and complies with local codes. While it adds $10 to $14 per square foot in labor costs, you'll benefit from their expertise, efficient work, and often a warranty on their craftsmanship. In the long run, a pro can save you time and prevent potential headaches, giving you peace of mind and a beautiful deck that stands the test of time.
