Decking Costs: What you need to know before building a deck

An outdoor deck is more than just an aesthetic addition to your backyard. It also helps extend living spaces, giving your family a cozy place to hang out at home. 

If you plan to build a deck, knowing more about the costs involved is vital to help you prepare your budget well. Here’s a quick guide about decking installation costs, including the different types of decks and the factors that could affect prices. 

How much does decking installation costs in the US?

There are three primary decking services: installation, repair, and replacement. You can expect to pay more for installation and less for repair and replacement. Here's a table listing the estimated deck costs per square foot.

What are the most popular deck materials?

The material used for your deck will largely affect the overall cost. Naturally, some types of deck materials are cheaper than others. Know that durability and aesthetics are also factors that can influence your choice of material. 

Treated pine

This is the most affordable decking material out there. It's the most common and easy-to-work-with decking material option, which you can leave clear, stained, or painted, depending on your preference. On average, you can build a 100-square-foot pressure-treated pine deck for around $2,100.

Hardwood timber

Timber decks are more costly than treated pine or recycled plastic ones, but they last longer if properly maintained. You can find a range of hardwood decking to match the flooring throughout your property. For example, mahogany hardwood decking costs $30 to $50 per square foot.

Composite decking

This kind of synthetic decking is an excellent alternative to wood. It's a wood-polymer composite that has become popular for being the more environmentally friendly choice. While low-maintenance, it isn't completely resistant to mold and mildew.

What are the factors that affect decking costs?

If you're curious about how much a deck costs to replace or install, these variables can influence your total project expenses:

Deck size and shape 

Decking costs can vary based on the size and shape of the structure. The number of decking boards you'll need and the job's complexity will be determined by the size and shape of your deck. It takes more time if the deck's proposed shape is curved and has multiple levels.

Project scope 

Minor deck improvement projects are doable in a shorter time and require fewer materials, but they also don't need planning permission. On the other hand, a bigger deck renovation or installation project needs a licensed contractor and regulatory permits. 

Location and labor

The requirements for planning permits and decking costs vary per state. Some areas have more miscellaneous fees and more expensive materials than others. You can check with your local council regarding regulations and your contractor about licenses and additional costs.  

The location can also affect the labor cost depending on the average rate in the area. For example, work in urban places can be more expensive because of higher contractor rates and high-end materials. You can expect to pay $20 and $25 per square foot to install an average-size deck.

Condition of the installation site 

Garden decking services can be more expensive if the area or surrounding structures need more work done. Properties that have not been maintained in a long time will require a more thorough cleaning even before the land is assessed. 

Accessories and decking features

Apart from the materials, additional accessories and features will also determine the total cost of the installation service. Extra nuts and bolts or timber for bearers and joists for your deck can increase the price.

Luxury accessories like deck heaters can cost $100 or more. Elevating your deck as a feature can also raise the price since it's more labor-intensive and might require more materials and accessories. 

Demolition work

If you want to renovate and completely change an existing deck (e.g., upgrade the materials and add features), you must consider the cost of demolition. You can ask your contractor for a quote that includes your new decking project's pre-construction or pre-installation process.
