Aluminum Deck Installation Cost & Price Guide

Aluminum decking is a premium decking material that lasts indefinitely. The best products are coated to make the deck slip resistant and quiet. There’s no metallic “ping” with high-quality coated aluminum decking.

Most aluminum planks feature a built-in water control system. The decks are installed with a non-noticeable slope away from the house, so most of the water runs off the deck and into a gutter. What seeps through the seams falls into a continual channel that carries it away from the house.

This design makes the deck waterproof, meaning the area below the deck doesn’t get wet. It can be used for dry storage or, if the deck is elevated, sheltered outdoor space.

This aluminum deck buying guide gives you comprehensive information to help you decide if this is the right deck material for your home. Use it to compare aluminum decks with PVC, composite, cedar, pressure treated wood and other materials covered in our deck buying guides. We’ve included aluminum decking costs, pros & cons, features and more.

What is Aluminum Decking?

Decking AluminumAluminum is a lightweight metal with impressive strength. Most aluminum decks can handle 225-260 pounds per square foot with joists spaced 16”.

The aluminum is extruded and then powder coated with an extremely durable, fade-resistant material such as polyurea elastomer. Manufacturers like Versadeck offer texturing options such as coarse to create more grip. One or two coats can be applied.

Most aluminum decking comes in planks 6” wide. Standard lengths are 12” to 20” in 2” increments, and special orders of planks to 40” can be made from some producers.

Things to Consider when Choosing Aluminum Decking

The price is the main consideration. Your upfront cost for aluminum is high, but since the deck rarely needs to be washed and never requires staining or sealing, your future costs are nearly zero for the life of the deck.

From a price perspective, if you plan to live in your home 10 years or more, aluminum can be cost-competitive with composite and hardwood decking because those materials require ongoing maintenance. It takes 15 years or more to recoup the cost when compared with pressure treated lumber decks and cedar decks.

Advantages of Using Aluminum for your Deck

There are both pros & cons of aluminum decking. Let’s start with its benefits:

  • Long-lasting material that won’t crack or warp
  • Weight is half that of wood, and it is much stronger
  • Only maintenance is washing if needed
  • Very resistant to staining, mildew and algae
  • Never an insect problem as with wood decks
  • Skid resistant surface
  • Fade resistant powder coating
  • Class A rating, so won’t burn, and melts at 1,200 degrees F
  • Stays cooler in direct sun than PVC, composite and wood
  • Longer plank lengths reduce seams and speed installation
  • Lifetime warranty on most aluminum decking

Disadvantages of Using Aluminum for your Deck

There are a few of aluminum decking cons to keep in mind as you compare deck materials.

  • More expensive than PVC, composite, cedar, PT lumber and most hardwood deck material
  • Available in a limited number of colors – 3 to 6 from most manufacturers
  • Cutting the aluminum is difficult, and a carbide-tipped non-ferrous saw blade is required
  • Poorly installed aluminum decking might squeak
  • Poorly coated or worn aluminum decking can be noisy when walked on

How Much Does it Cost to Build a Deck Using Aluminum?

Let’s start with the cost of the aluminum planks:

Aluminum Deck Plank Dimensions Cost Per Linear Foot
6” aluminum planks $6.70 to $11.00

Most aluminum deck frames are built from pressure-treated lumber. When the frame is included along with deck posts, rails, accessories and a gutter on the fascia with downspouts, your aluminum deck estimates should fall into these ranges:

Aluminum Deck Material / Labor  Cost Per Square Foot
Material $13.60 to $26.00
 Labor $4.75 to $10.50

There are several factors that determine your exact aluminum deck costs:

  • The better the quality of the material and its coatings, the higher the price will be
  • Aluminum decking with built-in water control costs 50%-100% more than decking that does not
  • Decks that are more complex with features such as multiple levels and stairs, intricate designs and more than four corners cost more than simple rectangle-shaped decks on one level
  • Decks built by a professional deck builder will cost more than a DIY deck or one built by a handyman
  • An aluminum deck built in the peak season will cost more than one built when contractors are less busy

Maintenance and Care of a Deck Built with Aluminum

Aluminum decking requires less maintenance than any other material.

  • Hose off debris, dust and spills
  • Power wash with low pressure, in the 1,000 to 1,300 psi range (though power washing isn’t necessary)
  • Inspect the deck once or twice a year to find and repair loose fasteners or planks
  • Snow should be removed with a broom rather than a shovel to prevent damage, as is true with every deck type

Aluminum Deck FAQ

Here’s a short aluminum deck Q&A that covers additional important topics.

Is an aluminum deck worth the extra cost?

It all depends on your preferences. Cost aside, if you want the ultra-low maintenance of an aluminum deck and like the looks, then yes, it’s worth it.

The waterproof design is a feature that allows you to use space under the deck without being dripped on, or to store items where they’ll remain dry.

From a cost perspective, keep in mind the longer payback period relative to other materials, as noted above.

Where is aluminum decking sold?

Much of it is sold by manufacturers directly to the public. You might find some aluminum decking in home improvement stores, but it isn’t typically the best-quality products.

How do you get aluminum deck estimates?

Typically, the manufacturer’s web page will include design software. You provide input about the size and shape of the deck you want to build, and the software creates a design and materials list for the project. This feature can be used by homeowners for DIY installation and by pro deck builders creating decks for clients. You can call most companies for assistance with design.

How much does the decking need to slope?

Minimum requirement for most materials is 1/8” per foot which isn’t enough to notice but will allow water to run away from your home.

Can the material be ripped lengthwise?

Most can be, and the cut edge can be covered with trim.
