Composite Decking vs Wood Decks in Wisconsin: Cost, Maintenance, and Durability Compared

Not the Composite Decking You Remember

When you think about a deck made of composite materials, what comes to mind? If you’re remembering plastic-looking boards that don’t resemble any wood found on earth, it’s time for a reality check. That may have been what composite boards looked like in the 1990s, but modern composite decking design is far more advanced.

Thanks to 30 years of scientific and technological advancements, today’s composite decking is virtually indistinguishable from natural wood, yet without the dangers of splinters, cracks, or uneven surfaces that can cause injuries. High-quality composite boards feature realistic grain patterns, color blending, and natural-looking highlights and lowlights, just like real wood planks. 

A finished composite deck looks natural, polished, and consistent throughout. Your deck looks great from day one and continues to provide an inviting, comfortable, and easy-to-maintain space for years, if not decades, to come.

Composite Decking Requires Less Maintenance Than Lumber

Annual upkeep, especially after a harsh Wisconsin winter, is one of the most significant differences between lumber and composite decking. Without regular maintenance, lumber decks can go from a beautiful space to an ugly eyesore surprisingly quickly.

Lumber decks are commonly built from pressure-treated wood or hardwoods, meaning they need attention to be protected from moisture, sun exposure, and temperature changes. To preserve your wood deck, you’ll have to set aside time each year to:

  • Address splinters and surface wear with sanding
  • Check for rot, cracking or insect damage
  • Repair or replace individual boards
  • Re-stain and reseal part or all of the deck

If that sounds exhausting, and you’re thinking you’d rather be spending that time actually enjoying your new deck, a custom composite deck is the better choice.

Composite decking blends recycled wood fibers and polymers to replicate the appearance of natural wood—without the onerous upkeep. Composite decking, especially high-quality products like TimberTech, offers superior durability and consistency that resists rotting, splintering, and fading.

That means you get all the enjoyment of the look of wood, without the constant work and stress. In fact, staining, sealing, and painting are unnecessary and are actually discouraged. For your composite deck to continue looking its best, your maintenance tasks are just to:

  • Keep your deck clear of organic debris
  • Clean with mild soap and water as needed
  • Prevent scratches by avoiding metal tools or unpadded furniture

When you compare the effort required to maintain wood with the simplicity of composite materials, the difference becomes hard to ignore.

Is a Lumber Deck Really More Affordable?

Making major changes or additions to your home typically presents two additional questions: What will this cost now, and what will this cost over time?

At first glance, a lumber deck can seem more cost-effective than composite decking. In a side-by-side comparison, a wood deck can initially cost around 32% less in Wisconsin. But before making your final decision, you might want to consider the true long-term cost of wood.

All that maintenance listed above comes with real expenses. Beyond your time investment, you’ll need to budget for stain, sealant, sanding materials, replacement boards, and labor. Even with the most diligent maintenance, a pressure-treated wood deck typically needs to be completely replaced within 10 to 20 years—about thirty years before your composite deck will even look worn.

By the time you need to replace your lumber deck, you may have already spent an average of 16% more than you would have on a composite deck. So, the answer to your question, “Is a lumber deck really more affordable?” is no. Composite decking can cost more upfront, but its long lifespan and minimal maintenance mean lower overall costs.

How Wisconsin Weather Affects Your Deck

The weather in southeastern Wisconsin will put extra stress on any outdoor structure, but especially wood decks. Weeks of below zero temperatures, repeated freezing and thawing, heavy snowfall, and the occasional ice storm mean deck durability is constantly punished by cold and moisture. Add humid summers to the equation, and you can see why decking materials that lack durability don’t last long in Wisconsin weather. 

In Wisconsin, wood decks are destroyed by the brutal cold, repeated freezing and thawing, and heavy snow.

Because wood naturally absorbs moisture, lumber decks constantly expand and contract with temperature fluctuations, leading to warping and cracking over time. Even when properly cared for, wood decks are vulnerable to weather-related damage.

Composite decks, especially those that use high-quality materials like TimberTech, are built to withstand extreme weather. TimberTech composite decking consists of two parts: the interior core and the exterior cap. 100% of the core is made from plastic that would otherwise end up in a landfill, while the protective cap is a high-performance, proprietary polymer blend that resists cracking, fading, and moisture.

This means a composite deck is designed to resist exactly what a lumber deck is most vulnerable to: moisture penetration, mold and mildew, UV fading, and even insect damage. That added durability helps ensure your deck will be there for you and your family season after season, year after year.
