Done With the Wood Deck Maintenance Cycle?

Traditional wood decks in Wisconsin quickly degrade: they split, hold water, grow mold, and need yearly maintenance. Composites fare poorly too, often fading, warping, and becoming slippery.

Outdoor Oasis, Milwaukee’s authorized Sunspace dealer, installs the Sunspace AlumaDeck system—a durable, 100% aluminum decking solution. It eliminates rot, warping, and seasonal maintenance, outlasting all other materials. We handle all custom deck installations, new or replacement, with our own trained crew, guaranteeing no surprises.

● System Selection

Sunspace AlumaDeck Decking System

Sunspace AlumaDeck Decking System

Wood gives you splinters. Composite gives you fading and heat. AlumaDeck gives you a deck surface that handles everything Wisconsin throws at it without a single coat of stain, a single replaced board, or a single seasonal worry.

Constructed from powder-coated aluminum with a non-slip finish, AlumaDeck planks install on both aluminum and wood substructures, integrate directly with Sunspace railing and sunroom systems, and are available in six colors that replicate the look of natural wood without any of the upkeep.

  • Self-spacing design speeds up installation.
  • Powder-coated non-slip finish for secure footing.

● Comparison

AlumaDeck vs. Wood vs. Composite

Not every homeowner is starting from the same place. Here is how AlumaDeck compares against the two most common alternatives across the factors that matter most for a Milwaukee deck installation:

Feature AlumaDeck Aluminum Pressure-Treated Wood Composite / PVC
Maintenance required None, lifetime Annual sealing and staining Periodic cleaning, some refinishing
Rot and moisture damage None, aluminum does not absorb moisture High risk, especially at post bases Moderate moisture can cause swelling
Mold and mildew None Common in Wisconsin humidity Common between boards
UV fading None, powder-coat finish Significant without annual treatment Fades within 5 to 8 years
Surface heat Cool to the touch, thermal conductor Moderate Very hot in direct sun
Slip resistance Non-slip powder-coat finish Slippery when wet or aged Slippery when wet or algae-covered
Fire resistance Up to 1,220°F Standard, not rated Varies, some melt
Freeze-thaw performance No warping, cracking, or splitting Checks, cracks, and heaves Warps and gaps in extreme cold
Environmental impact 100% recyclable, non-toxic Pressure-treating chemicals Non-recyclable, some off-gassing
Lifespan Guaranteed to outlast wood and composites 10 to 20 years with maintenance 15 to 25 years
Color options 6 natural woodgrain and solid finishes Stained to preference Limited manufacturer palette
Sunspace Compatibility Full integration with railings and sunrooms Partial Partial

AlumaDeck is the right choice when you want to build once, skip the maintenance cycle entirely, and have a decking surface that integrates cleanly with a railing, sunroom, or patio cover system without mismatched materials or separate warranties.

Why Milwaukee Homeowners Are Replacing Wood and Composite Decks

Wisconsin's climate is hard on outdoor surfaces. The combination of hot, humid summers, heavy spring rain, freeze-thaw cycles that swing 100 degrees between January and July, and UV exposure that fades finishes within a few seasons means that most decking materials are working against your climate from day one.

Here is what Milwaukee homeowners tell us before reaching out for deck installation:

We have refinished this deck three times in eight years. It looks worse every time.

Our composite deck is faded, and the surface gets slippery when wet. It is a liability.

We have mold growing between the boards every spring. It comes back no matter what we use.

We want something that looks great, matches our railings, and we never have to think about again.

Our wood deck is rotting at the post bases. We want to do this once and do it right.

The Sunspace AlumaDeck system permanently solves common decking issues. Aluminum prevents mold/mildew by not absorbing moisture, avoids warping/cracking from freeze-thaw because it doesn't expand, and its powder-coat resists UV fading. As a thermal conductor, it also stays cool to the touch, even on hot days.

● FAQs

Frequently Asked Questions

AlumaDeck is a 100% aluminum decking system manufactured by Sunspace. Unlike composite or wood alternatives, aluminum does not absorb moisture, so it cannot rot, warp, or grow mold. The powder-coated finish does not fade from UV exposure the way composite decking does, and the non-slip surface stays safe and cool to the touch year-round. AlumaDeck is guaranteed to outlast any wood, membrane, or plastic-based decking product.

Aluminum deck installation pricing depends on the square footage of your project, whether the installation involves a new substructure or a surface replacement on an existing frame, and whether railing integration is included. We provide a free, detailed, itemized quote after your in-home consultation. There are no surprise charges and no estimates that change after the fact.

In most Milwaukee-area municipalities, a new deck installation or significant structural alteration requires a building permit. Requirements vary by suburb, deck height, and square footage. We manage all permit applications and HOA submissions on your behalf across Milwaukee, Waukesha, Ozaukee, and surrounding counties.

Yes. AlumaDeck is compatible with both aluminum and wooden substructures. If your existing wood frame is structurally sound, our team can install AlumaDeck planks directly over it, replacing only the failing surface. Our crew evaluates your existing frame during the free consultation to confirm whether it meets the requirements for a surface replacement.

No. Because aluminum is a thermal conductor rather than a heat absorber, AlumaDeck stays significantly cooler to the touch than composite or wood decking in direct sun. This is a meaningful advantage on south-facing decks in Milwaukee, where afternoon UV is intense from June through August.

AlumaDeck is available in six standard powder-coat colors: Grey, Cedar, Grey Woodgrain, Sand, Taupe, and Spruce. All finishes are engineered to resist UV fading, chalking, and chipping through Wisconsin’s climate without any refinishing required.

Yes. AlumaDeck is saltwater tested and fully suitable for lakefront decks, docks, and waterfront applications. Aluminum does not corrode in wet or high-humidity environments the way wood fasteners and composite cores can, making it a strong choice for properties along Wisconsin’s lakes and rivers.

Most surface replacement projects on existing frames are completed in one to two days. New build projects with substructure, stairs, and railing integration typically take two to four days. Permit processing, when required, adds two to four weeks before installation begins. We initiate permits immediately after design approval to minimize schedule delays.

Yes. AlumaDeck is 100% recyclable and free from the harmful toxins found in pressure-treated wood and some composite products. It does not off-gas, does not leach chemicals into soil or groundwater, and can be fully recycled at the end of its useful life.

Yes. AlumaDeck is specifically designed to integrate with Sunspace railing systems and sunroom additions. If your project includes a railing upgrade, a louvered pergola above the deck, or a sunroom connection, Outdoor Oasis coordinates every element as a single scope of work with one crew, one permit process, and one warranty.
