Composite Options
If you can imagine it there is probably a composite product to fit it. Composite decking manufacturers such as TimberTech, Trex and Deckroators offer dozens of color, style, performance and price point options. Every brand and every line will offer different benefits; they are generally categorized into entry level, mid-tier and high-end lines.
Entry Level
Entry level composite decking is usually meant to be a competitor against traditional wood decking while still offering the benefits associated with manufactured product, creating a great bang for you buck option. Most manufacturers offer their entry level lines in two or three colors options.
Mid-Tier
Mid-tier composite decking options will start to offer more color/style options along with varying upgrades in performance, such as enhanced traction. You also see more realistic styling in the mid-tier options such as better wood grains and coloring profiles. Mid-tier composite decking also gives the design process more flexibility due to the ability to fit the bill for a wider range of unique applications.
Top-Tier
This is where all the best in composite decking technology is bundled together. Better performance features such as cooling technology, direct ground or water applications, and ultra realistic styling are all found here. Top-tier decking also provides the largest selection of color, style and even board profiles allowing for the maximum in design creativity.

Railing Options
Composite decking may have a lot of options to choose from, but railing options to pair with the decking are even more abundant. Manufacturers such as Westbury, Fortress, or Regal ideas offer hundreds of possible combination options.
Materials
Railing systems built for composite decks can be made of a multitude of material types. Some common railing materials are steel, aluminum, cable, glass, composite, and vinyl. Sometimes these materials are standalone and sometimes they are paired together, each one has their owns et of pros and cons.
Durability
Durability can be impacted by outside factors for any individual deck but there are still some commonalities that can be applied. Generally metal railings with proper and well produced coatings will outlast all other railing types. Metal railings will be weather resistant or weatherproof and be solid enough to withstand even the toughest households. Glass and cable rail can also offer high durability in static environments, however factors such as extreme weather or rambunctious children can increase the risk if damage or premature failure. Composite or vinyl railings will offer some of the greatest design options but will generally be the least durable of the group. That’s not to say composite or vinyl railing is going to fail out, the technology used to produce them is well vetted, however they will still be the most prone to damage from weather events, hard use or time in the outdoors.
Cost
Generally speaking, railings can be one of the biggest material costs for a deck project, especially special order or custom options. Glass and cable railing tend to carry the heftiest price tags, especially if the project requires custom applications. Aluminum comes next in price, followed closely by steel. Composite and vinyl options are usually the most cost effective, although manufacturers or styles can still surpass other material types in some cases.
At Apex Homes we love aluminum railing and use it as our preferred recommendation, to learn more about why we choose aluminum and everything else there is know about deck railings check out our article HERE
What it takes to build
Prep
Arguably the most important step of any project, and sometimes the most difficult. Project preparation as soon as a project is given the green light, most of it occurring behind the scenes. This is where the site layout and deck design will be finalized, and material selections will be made. A key part of this phase is calling in a utility location request to ensure all locations of underground utilities to your house are accounted for in the design process. Once we have determined where the deck is going and what we are using to build it detailed plans must be drawn and submitted to the proper entities to obtain our building permit. This process can take anywhere from and few days to a few weeks depending on the complexity of the project.
Demo
Remember when we mentioned how every project is different, well some project might exclude this step entirely if there are no existing obstructions for your new deck. Most of the time though there is plenty to remove before we can start with a clean slate. Lots of projects will require demolition of old existing decks prior to a new one being built; sometimes this can include old concrete footings or pads that are no longer viable to be used due to damage or current code requirements.
Footings
Anything that is solid in life must start with a good foundation, decks are no exception. Footings size and layout will vary greatly depending on your project, but regardless this is where all the time and effort spent during the Prep phase start to pay off. First, we confirm that the drawn plans and utility locations do not interfere with the onsite layout. After the layout is confirmed, the footings must installed, which can look one of two ways: traditional concrete pier footings or manufactured footings systems. Traditional pier footings must be dug, inspected by building inspectors, poured, allowed proper cure time, and then built on. Manufactured footing systems are pre-cast engineered systems and can be inspected at any time during the project, saving valuable time. To learn more about our preferred manufactured footing system, Diamond Piers, check out our article about their pros and cons and installation method HERE
Framing
This is the first step where the extreme visual progress of your new deck can be tracked. Overall layout of the deck as well as the posts, beams, joists and blocking are crucial to making sure framing runs smoothly. Framing is usually a fast process within a deck build, however it takes extreme care to ensure that the final visible product comes out perfect.
Decking and Railing
This is the most exciting step in the building process. This is where all the careful planning throughout the rest of the project timeline all comes together. Decking will be laid, picture frames and inlays will be cut in, railing posts and sections will be spaced for uniformity and in deck lighting will be installed.
Finish
Now your deck is built and all that’s left are touch up details, final cleanup and our walkthrough to make sure everything is exactly how you envisioned it. All that’s left after this is years of enjoyment and memories.
Cost to build a composite deck
As you’ve now learned simply giving a cost isn’t just as simple as picking a deck size and having a price. There are dozens of selections and circumstances that will influence the cost of your composite deck project. Along with your materials selections; factors such as deck height from ground, site accessibility, and existing house design are just some examples of price influencers. You also must consider your specific contractor; as the saying goes, you get what you pay for. However, below are some general prices you might expect to pay for different size decks based off general sizes and entry to top-tier material selections.
Small 12x12 - $10,000 to $20,000
Medium 16x16 - $16,000 to $28,000
Large 16x24 - $20,000 to $35,000
