Madison Deck Builder Reviews

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.” – Donna R.

Our Deck Building Process

STEP 1: Tell Us About Your Deck Building Project

If you live in the Madison area, begin the process by sending us a short message describing your deck-building project. Whether you know exactly what you want your composite deck to look like or are just getting started, we’re excited to hear from you!

Too excited to wait? We get it. Feel free to call 3rd Gen’s deck-building team directly!

STEP 2: Schedule Your Free Estimate or Deck Inspection

One of our trusted deck experts (Matt or Alex) will work with you to schedule a time to walk around the project site together. Already have a deck? We can inspect any existing decking structures to provide honest feedback regarding recommended repairs or replacements. Starting from scratch? We’re elated to explore all the possibilities with you. Let us know if you have any specific decking ideas or preference on decking materials. Otherwise, we’ll walk you through our favorite options for high-quality composite decking brands that last!

We can also show you what might be possible in terms of layout & provide a rough ballpark on pricing, all while keeping your budget in mind! Within just a day or two, we’ll send you a detailed deck building quote. If you have any questions about your deck project, we’ll happily take the time to answer each of them so you can feel confident moving forward! After all, this is your home… we want you to LOVE the final result. We’re building an outdoor oasis, remember?

STEP 3: Deck Design and Material Selection

While our talented deck builders gear up to start your project, our rockstar production coordinator, Autumn, will meet with you to finalize material selection, colors, and fixtures. During this step, we’ll remind you of what you can expect during 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.

When it’s time to start your project, we’ll prep the worksite. More specifically, this includes taking apart existing structures as needed and outlining the new deck area (taking extra care around any underground utilities). Because we use top-quality materials in every step of your deck build, we don’t have to dig massive holes for footings. Using Diamond Piers, we’ll disrupt less of your lawn… and we get to build year-round (even when the ground is frozen)!

STEP 4: Let’s Build Your Dream Deck in Madison

This is where we make your dream deck a reality… At the beginning of this step, we’ll set your footings (using Diamond Piers), secure the beams, posts, and joists to build deck framing that lasts.

Then, we’ll secure the deck floor boards & if we’re using our favorite composite decking material, we will use special hidden fasteners to cover any unsightly screws and give your deck a finished look.

To make sure your new space is as safe as it is gorgeous, we’ll install any remaining items on your deck building checklist including: railings, stairs, fascia, benches, planters, skirting, lattice, pergolas, & custom lighting.


Remember how we said we treat our clients the way we want to be treated? That includes picking up our mess. We’ll dispose of all demo materials & recycle excess supplies if possible. If your new deck is dirty from our work boots, we’ll also power wash it so all you have to worry about is what kind of furniture you’re going to put on it!

If your new structure is made of wood, we can also stain, paint, or seal the deck at this point if it’s ready for coating.

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

3rd Gen installed our deck over the winter, something I didn’t know was even possible. They had minimal delays after snow storms & on severely cold days, but they kept in close communication & worked every day it was feasible. The deck is beautiful. They totally met my every expectation.

Kris R.

Thank you for our new deck! We’re so happy to have a maintenance-free deck with long lasting materials.

Working throughout the hottest week of the summer, Eric and Johnathan got everything done AHEAD of schedule! Truly impressive.

Madison Decks and Designs

We know 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. Our team members have seen hundreds of composite decks in Madison go from quick sketches to stunning structures. They can help steer you in the right direction on color and material combinations that will coordinate beautifully with your home.

AZEK TimberTech Composite Decking

A lot of people come to us thinking they want a Trex deck. At the end of the day, we’ll build whatever you prefer; however, if we’re being honest, AZEK / TimberTech comes with much greater value for multiple reasons.

Because we really love talking about decks and decking materials, we created an entire guide to walk you through each of those reasons (along with some fun additions to consider for your deck). But remember… we don’t need you to become a deck expert to reach out to us. Our team is here to educate and guide you every step of the way!


Pssst… in case you’re curious what everyone else is loving, let’s walk through some of the most popular TimberTech PVC and composite deck floor colors in Madison.

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. Each Vintage Collection deck color offers a natural-looking style that works well with many different home types. As we mention in our maintenance free decking guide, AZEK Vintage is the most premium option in terms of aesthetic and quality.

Mahogany PVC 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 wood-mimicking PVC decking color blends seamlessly with different shades of dark brown wicker deck furniture and white or black railings. It truly is the perfect color for traditional or historic home exteriors often found in Madison.


Dark Hickory by TimberTech

Another popular deck color from TimberTech’s Vintage Collection is Dark Hickory. It’s dark, almost neutral tones make it a great pairing for most modern homes. It can also coordinate with most railing options beautifully.


Timbertech Coastline

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

The huge perk of this color is that it stays cooler than the two we mentioned above. Despite the fact that PVC and composite decking holds less heat than traditional wood, dark materials can still get warm. If your deck gets a lot of direct sunlight, it’s important to keep that in mind while choosing colors.


Coastline is named perfectly in the sense that it’s perfect for pool decks or balconies overlooking Lake Monona or Lake Mendota in Madison! As you can see, this popular deck color contrasts well with white trim, risers, and railings.

Two Tone Decking

All of the composite decks we build in Madison incorporate a picture framed style. This means the center deck boards are trimmed out with long boards around the edges to give it a more finished appearance as opposed to cut ends. 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.

A two-tone design adds a little more visual interest and can be a great way to tie into the home’s existing colors. In fact, as long as your colors come from the same decking material collection, opting for a two tone design doesn’t cost any extra!


Feeling overwhelmed with all the style choices? Remember… our deck building experts will guide you through each and every decision. After all, this process is supposed to be fun!

Composite Decking vs Wood Decking

If you’ve made it this far, you’ve probably caught on to the fact that many of our clients opt for composite decks. But is there ever a case where using wood to build your deck makes more sense? If you’re in Madison WI, just let one of our deck building experts walk you through the decision personally. Otherwise, read on!

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!

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 & plastic.

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


Composite Decks Benefits

  • More cost-effective over time because it doesn’t require regular staining or sealing.
  • Resists moisture better, so there’s less warping or rotting.
  • Doesn’t scratch as easily.
  • Allows for a more uniform, finished look.
Composite Decking Drawbacks
  • Initial cost to build is a bit higher.
  • Aerosol sprays can stain the boards – so avoid applying these types of sunscreen / bug spray on your deck!
  • Replacement boards may be difficult to match decades down the road.

Wood Decks

decking wood building madison wi

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

These types of decks have definitely been around the longest & you’ve likely 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 material cost is lower (if not using specialty lumber).
  • Able to change color as you please using stain & paint.
  • Replacing damaged boards is rather easy (but 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, which quickly adds up.
  • Costly wood rot can occur if the deck is not maintained.
  • Wood is now more expensive compared to years ago.

Typically, we only recommend wood over composite if you plan to sell your home in the next couple of years or if composite is just out of your initial budget. Because the dollar for dollar ROI on a wood deck is said to be about 5% higher than a composite deck when reselling, if you don’t plan to stick around (& don’t have to deal with the regular maintenance), wood may be the way to go. Though for a prospective buyer, already having a beautiful composite deck might be a nice perk…

In just about every other circumstance, our team is very pro composite. Curious exactly which composite decking materials we like best? Check out this guide for more info…

Deck Building FAQs

Do you pull all of the decking permits?

Absolutely — we’re here to handle everything from helping you choose materials until the final walkthrough.

You’d be surprised how many decks get built improperly (and without permits) in the Madison area. We usually get calls to fix it a couple of years later when it’s sagging, tilting, or someone gets a warning from their city.

As a licensed general contractor, we take permitting and building to code very seriously and will make sure your deck meets local ordinances so it’s safe for years to come.

Do I need to be here during construction?

Most of the time, no! Because we do a design consultation before each project begins to make sure we’re on the same page and finalize details, once we start, we shouldn’t need you.

There are exceptions, however. If you’re having a screen porch or three / four season room built, our electricians may need access to the home to run wire out to lights or fans.

That would always be communicated ahead of time so you know. But generally, our deck crews can just see themselves to the backyard and get to work!

Where will materials be dropped off & will your crew be here during delivery?

Like we’ve mentioned, communication is huge for us. So, before we start your project, we’ll confirm where materials and dumpsters (for any demo debris) can go to be out of your way.

Our crews will not always be there while material is delivered, but the driver will always have instructions on where to put it based on our previous conversations!

Once our crew arrives next, they’ll move your material to the area they’re building.

How far out do you book?

Spring, summer, and fall are very popular times. It’s not crazy for us to be booking out 2-4 months during peak seasons. That said, we also build during the winter and typically have slightly shorter lead times.

All in all, a few month wait time actually works out pretty well for us to finalize your material type and color so everything is set to go when we start your deck.

And if you have a specific deadline in mind due to a special event or life change, just let us know. We’ll be very honest about whether or not we can accommodate!


Do you have a showroom where we can look at materials?

We don’t have an official showroom, but our material supplier does. You’re more than welcome to visit theirs to see differently displays.

That said, we can do ya one better. Our deck experts will bring pamphlets / photos with to your estimate to walk you through each of your options.

Once you narrow down what you might be interested in, they can actually leave you with some real samples to touch & look at next to your existing home. While showrooms are beautiful and really fun, seeing what the products look like at your house is what really matters.

How long will it take to build my deck?

Every project is different! Building a small composite deck is much different than building a watertight 4 season room.

With a two person deck crew, we can finish an average sized deck in 7-10 business days.

Once we start a project, we stay on it until completion (with the exception of an occasional inspection delay). Our crews work M-F from roughly 8am until 4pm — weather permitting!

Can you just resurface my deck using composite?

In some cases, yes. However, during our estimates, our deck experts will assess your deck for structural integrity.

Depending on when (or how) your deck was built, we may actually have to rebuild to make it structurally sound & satisfy code requirements.

Additionally, composite decking materials have different framing requirements. So, most of the time, it makes more long-term and financial sense for us to rebuild the deck entirely rather than trying to retro-fit new materials.
