Custom Deck Building Review Fitchburg, WI

Fitchburg Deck Building Testimonial

Product quality and workmanship is excellent. I had a two level deck replaced and the workers went over it every step of the way. The owner, Matt, responded to all my questions within a day, sometimes within an hour. I’ve done a lot of remodeling and have never had that level of customer service.

Madison Decks and Designs

When it comes to composite decks in Madison, there are a few popular design choices that stand out. Likewise, the amount of deck color choices, deck brands, and deck designs can be overwhelming for most homeowners.

As one of Madison’s top deck companies, we’re here to help you through every step of the deck design process. Accordingly, we’ve put together this composite decking guide with our most popular deck styles to make it easy for you.

Timbertech Azek Composite Decking

By far, Madison’s most requested composite decking brand is Timbertech Azek. This composite deck board is made from a solid PVC composite material with an extremely realistic wood grain look. Not to mention, Azek decks are one of the most durable composite products on the market and can withstand stains, scratches, mold, and board splitting over time.


Another thing we really like about Timbertech Azek decks is the 50-year limited warranty they carry on many of their products. Because of its durability, realistic texture, and warranty, we’ve found that Azek is the best quality deck building material you can buy.

Top Composite Decking Materials in Madison, WI

Let’s start with the top picks for composite Timbertech deck floor colors in the greater Madison area. Azek Timbertech decking offers three design collections, Vintage, Arbor, and Harvest.

In Madison, Vintage is the most popular because it mimics traditional wood grain textures best. Additionally, the Vintage line by Timbertech seems to fit best within the architectural style of homes in Madison and greater Dane county.

Timbertech Decking Colors (Vintage Collection)

The three most popular deck color choices for composite decks in Madison within the Azek Timbertech Vintage collection are Mahogany, Dark Hickory, and Coastline. Indeed, each Vintage collection deck color offers a natural-looking style that works well with many different home types.

As a whole, this is a premium option when compared to other Azek offerings including their Harvest or Arbor collections.

Mahogany Composite Decking


Timbertech’s Vintage Collection color, Mahogany, is a medium brown deck color with a hint of red and darker streaking.

As you can see above, this natural-looking composite decking color blends seamlessly with different shades of dark brown wicker deck furniture and white or black style railings.

Dark Hickory by Timbertech Azek

Another popular deck color from Timbertech’s vintage collection is Dark Hickory. Another natural-looking composite deck shade, it works well as a dark contrast to vibrant deck furniture and lighter home styles.


Similarly, this darker Azek deck color adds a modern touch when combined with classic or historical home exteriors often found in Madison, WI. Lastly, we’ve seen that the most popular rail combo chosen with Dark Hickory is a brown aluminum composite railing.

Timbertech Coastline

The next most requested composite decking color is Coastline by Timbertech. This Vintage collection standout is a lighter gray decking color that still retains a natural wood look.


Moreover, this popular deck color contrasts well with white trim, risers, and railings. Likewise, it offers a modern coastal gray style perfect for a pool deck or balcony overlooking Lake Mendota or Lake Monona in Madison.

Picture Frame Composite Deck Styles

In terms of deck board layouts, most of our clients in Madison choose to picture frame their composite decking. When it comes to composite decks, picture framing is a layout where deck boards line the perimeter of a flooring area to form a block around your inlay deck boards.


No question, this popular deck floor style allows for a sleek and modern finish to your decking installation project. Simultaneously, picture framing your deck allows you to think “outside the box” in terms of color combinations.

As a result, the picture frame style gives you the custom design option of a beautiful-looking two tone decking color combination.

Two Tone Decking

A majority of the composite decks we build in Madison incorporate the picture-framed design described above. With this option, you can either choose to match the picture framing to the infill deck boards or opt for a two tone decking style.

Accordingly, a two-tone design creates a modern, sleek finish to your job. In fact, nearly 90% of homeowners that choose picture framing also opt for a two-tone deck design.


Notwithstanding, the two tone composite decking option gives your deck a custom-looking masterpiece you’ll enjoy for summers to come.

In case you are overwhelmed with style choices, keep in mind that 3rd Gen’s deck building team in Madison typically will guide you through all of these steps to make it easy.

Composite Deck Railings

Now that you have selected your composite deck board colors and design, you are ready to select your composite deck railings.

Many of our Madison area customers either try to match the picture frame floor color to the deck railing or opt for something similar.

However, you can use your deck railing selection as a contrast to your flooring choice as well.


Nonetheless, choosing a composite decking railing is simpler than choosing deck flooring as the selection is limited. When it comes down to it, most people choose black, dark bronze or white deck railings to coordinate with their composite boards.

Based on the Azek deck floor color you choose, the most common deck railing combinations include:

  1. Mahogany with black railings
  2. Dark Hickory with bronze railings
  3. Coastline with white railings

Next, we’ll explore the most popular choices for composite deck railing system products.

Timbertech Deck Railing

By far, the most popular railing products that Madison homeowners go with are Timbertech deck railings. Timbertech deck rail systems coordinate perfectly with most composite colors and add to the modern finish of your decking project.

Moreover, Timbertech offers two different deck railing system material options, aluminum, and composite.

Aluminum Railings (Timbertech)

The aluminum railing product line by Timbertech is named Impression Rail Express and offers three top rail options as well as three color choices. This low-maintenance aluminum railing option is popular among Madison homeowners and known as a sleek but durable deck railing system. In addition, it is both stain and scratch-resistant and carries a 25-year limited warranty.


As referenced above, Timbertech’s aluminum rail offering comes in three colors: black, dark bronze, and white. Furthermore, you can choose a classic rail top, drink rail style, or a modern top rail design that has an updated boxed finish.

Composite Railing By Timbertech

Timbertech’s composite railings are aptly named the Classic Composite Series. This simple and seamless composite railing is resistant to moisture, mold, fading, and staining over time. The composite railing itself is constructed with solid balusters and has thick walls which makes it extremely sturdy.

Not to mention, the powder-coated finish is corrosion resistant which increases the railing’s lifespan. As a result, this durable deck railing holds up well to the heavy snow accumulation during the rough Madison winter season.

One additional feature of this very durable deck railing is that it’s made from up to 50% recycled materials which is great for the environment. Similar to Timbertech’s aluminum railing line, their composite railing system comes with a 25-year limited warranty. Currently, the composite rail has five different rail top shapes and only comes in black, white, and matte white.

Westbury Railing

A popular high-end deck rail option is the Westbury railing system. This elegant deck railing system is fade-resistant and offers a permanent finish that requires little to no maintenance. An additional key point is that Westbury railings are aluminum-based and carry a lifetime warranty.


Whether you are building a balcony or multi-level composite deck, Westbury’s railings are powder coated for maximum longevity through treacherous Wisconsin winters. Available in twelve colors, the most popular rail top and baluster style is Westbury’s Tuscany railing style.

Tuscany aluminum railings feature a classic two-rail design and come in a wide range of finish styles including satin, textured, and multi-colored finishes. Last but not least, Tuscany deck railing systems offer both rounded (C101) or squared (C10) rail baluster styles.

Free free to call 3rd Gen’s deck-building team as well if you are on the go!

Next, Schedule Your Free Estimate or Deck Inspection

Matt or Alex will schedule a time to walk around the project site together and inspect any existing decking structures with you. During which, you can describe any decking ideas you may have and decking materials that you may want to use.

Additionally, they will show you what is possible in regards to your deck and may be able to give you a rough ballpark on pricing.

Lastly, we will send you a detailed deck building quote within the next few days (don’t worry, you can request changes to the proposal as needed before approval).

After That, Deck Design and Material Selection

We will meet with you before your project to go over material options, colors, and fixtures. During this step, we can provide a rough mock-up of your deck building project along with project scheduling details.

This step also includes pulling permits and submitting the plans to our local Madison deck building department.

Lastly, we will prep the worksite. More specifically, this includes taking apart existing structures as needed and outlining the new deck area. Followed by an inspection of underground utilities, removing sod, preparing the soil, and digging holes for footings.

Last, Let’s Build Your Dream Deck in Madison!

This is where your dream deck for your home starts to become a reality!

At the beginning of this step: we will set footings, secure the beams, posts, and footers to build the deck framing and supports.

No doubt, your decking project will really start coming together as we install the joists, secure the deck floor boards, and start trimming the decking.

Next, we will install any remaining items on your deck building checklist including:

  • Deck railings and trim
  • Deck Stairs and Landings
  • Benches & Planters
  • Trellises, skirting, and Privacy Fencing
  • Pergolas or Sunshade Installation
  • Custom lighting and Decor

What follows is a full cleanup of the job site. Don’t forget, we dispose of all demo materials and recycle excess supplies if possible. Not to mention, we can also stain, paint, or seal the deck at this point if it’s ready for coating.

Finally, a final walk-through will be performed with you to ensure you are 100% satisfied with the workmanship of your brand new deck!

Composite Decking vs Wood Decking

You have probably heard of composite decking by now but what is truly the best decking material to use for your next job?

Next, we separate fact from fiction when it comes to comparing wood decking vs composite decking.

To help you make the best decision for the surface of your deck, we’re going to walk you through the differences between composite and wood decking. We’ll analyze the pros and cons of each so you can feel confident with your choice! Let’s get started!

Composite Decks

composite-decking vs wood

Composite decking is a bit newer to the market and has been lauded as the ultra-durable maintenance-free decking material of the future.

In basic terms, composite decking is just how it sounds… It’s a hybrid material made using both ground-up wood and plastic.

Because of the plastic elements, it has many benefits and drawbacks that wood does not:

Composite Decks Benefits

  • A little cheaper to build because the material cost is lower.
  • You can change the color & finish of the deck as often as you’d like using stain or paint
  • Replacing damaged boards is rather easy (although staining to match the rest of the wood on the deck is a different story)
Composite Decking Drawbacks
  • A bit more expensive than wood decking
  • Certain liquids may cause blemish spots (spray-on sunscreen or bug spray)
  • Replacement deck boards or fixtures may be hard to find down the line

Wood Decks

The two main types of wood decking are pressure-treated lumber & cedarwood decking; however, other hardwood options are available at a higher cost such as redwood, IPE, or bamboo.

These types of decks have definitely been around the longest and you have surely seen them around your neighborhood.

Regardless of the type of wood, the pros and cons are about the same:

Pros of Wooden Decks

  • Slightly cheaper to build because the material cost is lower
  • You can change the color & finish of the deck as often as you’d like using stain or paint
  • Replacing damaged boards is rather easy (although staining to match the rest of the wood on the deck is a different story)
Cons of Wood Decks
  • Wood wears, weathers, and warps over time
  • You must stain, paint, or reseal your wood deck every 2-5 years
  • Costly wood rot can occur if the deck is not maintained
  • Wood is now very expensive compared to years ago
