Aluminum Decking Price Guide

Aluminum decking is becoming an increasingly popular choice when it comes to deck building. Homeowners enjoy this material's durability and the fact that it is resistant to water damage, mold and termites over time. The possibilities when it comes to aluminum deck installation are essentially endless. These decks can be built to suit any homeowner's desires, whether one is looking for a small deck for personal use or even a large, double-deck built around a pool for outdoor gatherings. Any homeowner looking to make a wise investment in their homes should consider the option of having an aluminum deck installed at some point.

  • The maximum cost homeowners should expect to spend on aluminum decking is around $11.20 per square foot.
  • The minimum reported cost of aluminum decking is $10.01 per square foot.
  • The average reported cost for aluminum decking is $10.64 per square foot.

Advantages and Disadvantages of Aluminum Decking

As with any home improvement project, there are certain advantages and disadvantages that should be kept in mind before deciding to install an aluminum deck. The first and often largest advantage to using aluminum material to build a deck is that of durability. Unlike various types of wood and even composite materials, aluminum does not rot or attract mold growth over time, and it cannot be affected by termites like wood can, making it the most durable type of deck material on the market. 

The material itself is lightweight, which makes construction much easier and even less time consuming than traditional wood and composite deck projects. This can save homeowners money on labor and installation in the long run. Finally, aluminum is recyclable, so in the event that homeowners decide to remove or even replace parts of the deck over time, they can do so in a way that is environmentally conscious.

There are inherent disadvantages to going with aluminum materials for decking as well. Most homeowners agree that the biggest disadvantage is the cost. Aluminum decking is typically about twice as expensive as traditional wood or even composite decking. 

Some homeowners avoid aluminum decking because they prefer the more natural look of traditional wood. It is true that the same look simply cannot be achieved with aluminum, which is a drawback for some. This is not to say, however, that aluminum decking cannot be beautiful and aesthetically appealing in its own way.

Cost Considerations

Aside from the cost of materials for the standard-sized, 200-square-foot aluminum deck, it is also important to take into consideration other possible factors that can influence costs. On average, materials for an aluminum deck range between $2,000 and $2,500. The price-per-square foot, in many cases, will not include installation and labor costs. For this reason, it is important to clarify with a contractor or deck builder upon receiving an estimate whether or not that includes labor and installation. If not, homeowners should expect to add anywhere from $200 to $360 to the overall cost. It it not unheard of for even a small, 200-square-foot aluminum deck to cost around $3,000 when all is said and done.


One of the best things about having an aluminum deck installed is that they do not require much maintenance at all. Decks do not need to be sealed as they are already resistant to water and other elements. Unlike wood, aluminum can expand and contract in hot and cold weather without splintering or causing any other damage to the structure itself. And since mold does not grow on aluminum, there is no need to worry about moisture.

For the most part, the only maintenance aluminum deck owners need to worry about is keeping the deck clear of debris throughout the year. To keep the deck looking its best at all times, power washing the deck itself at least once per year is recommended. However, this is purely for aesthetic reasons.

Saving on Aluminum Decks

While aluminum decks are easily the most expensive type on the market, the good news is that there are some ways in which homeowners can go about saving money on these decks. Shopping around with various deck builders to find the best deal is important. This can be a time-consuming process, but it could ultimately end up saving homeowners hundreds of dollars down the road, so many people would agree that the extra time and effort is more than worth it. After all, most companies these days offer free estimates for homeowners interested in having a deck built.

Aside from shopping around, homeowners can possibly save money the cost of an aluminum deck by having the work done at slow times for the contractor or business throughout the year. During these times, it is possible that the business will have some special promotions and deals where the homeowner can save a significant amount of money on the overall cost. Often times, having one built in the fall is a good way to save money, especially in states when temperatures start to drop around that time of year.

Homeowners considering the option to have an aluminum deck installed should seek to get the best return on investment by having a Realtor look at neighborhood comps, so that they can make a recommendation in terms of how large of a deck should be built. From there, homeowners can enjoy the peace of mind in knowing that their new deck will not only be a great place to spend time outside, but will help them to boost the resale value of the home down the road as well.

All in all, aluminum decks can be a wonderful addition to any home, especially for homeowners who enjoy spending time and entertaining outdoors.
