Composite Decks in Wisconsin | Excel Custom Decks

Composite Decking

Wisconsin homeowners choosing composite decks are choosing the lowest-maintenance long-life decking option available. Excel Custom Decks is a family-owned residential decking contractor serving Wisconsin from offices in Franksville, Madison, and Appleton/Oshkosh. With 25+ years in business and 5,000+ projects completed, the company sits on the NARI board, holds BBB A+ accreditation, and belongs to NADRA, the Metropolitan Builders Association, the National Association of Home Builders (NAHB®), the National Association of the Remodeling Industry (NARI®), and the Wisconsin Builders Association. Every composite deck carries a lifetime labor warranty and material warranties up to 50 years from the manufacturer. Work starts with a free consultation covering brand selection, design, framing, and permitting.

What Composite Decks Offer Wisconsin Homeowners

Composite decks built from Trex decking, TimberTech decking, and other capped polymer products combine the look of wood with engineered durability that holds up through Wisconsin’s harshest seasons.

No Staining, Sealing, or Refinishing

Composite decks need soap and water and not much else. The capped polymer surface resists stains, fading, and moisture, which eliminates the annual sealing, periodic staining, and full refinishing that pressure-treated and softwood decks require. For Wisconsin homeowners who want to enjoy the deck instead of maintain it, that is the deciding factor.

Engineered for Freeze-Thaw and Snow Load

Trex decking and TimberTech decking are engineered to handle freeze-thaw cycles, heavy snow load, and prolonged UV exposure without surface degradation. The capped polymer layer keeps moisture out of the board core, which is exactly the failure mode that affects wood decking in Wisconsin winters.

Long Material Warranties

Major composite brands carry 25-year to 50-year material and fade-and-stain warranties. That coverage outlasts most pressure-treated wood decks and matches or beats softwood deck service life, without the upkeep.

Composite Decks in Wisconsin: Permits, Climate, and Material Decisions

Building composite decks in Wisconsin runs through the same permit and climate factors as any residential deck, with material-specific decisions layered on top.

Permit Authority

Composite deck permits get issued through the local building department. Wisconsin municipalities require permit-ready drawings with dimensions, framing details, and footing specifications at submission. Excel Custom Decks prepares the drawings and submits the permit directly.

HOA Communities

Wisconsin HOA communities sometimes restrict deck colors, board profiles, or material categories. Excel Custom Decks confirms HOA standards before finalizing composite brand and color choices.

Climate Factors

Wisconsin sits in USDA Hardiness Zones 3b through 5b with deep frost penetration and long freeze-thaw cycles. Composite decks installed with proper drainage, correct fasteners, and frost-depth footings perform well for 25 to 50 years with minimal upkeep. Capped polymer composites resist the surface fading, splintering, and moisture damage that affect uncapped or first-generation composites in Wisconsin's climate.

What a Composite Deck Build Includes

Excel Custom Decks handles composite decks from design through construction. Each piece of the build is spelled out in writing before any contract is signed.

Composite Deck Installation

Installation covers full construction from footing to finish, including foundation, framing, composite boards, railing, and skirting where specified. Every composite deck is built to Wisconsin building code and permitted through the local municipality.

Design Consultation and 3D Models

Design consultation walks through layout, elevation, brand selection, color, board orientation, railing style, and skirting options. 3D deck models give the homeowner a visual of the finished composite deck before permit submission so brand and color choices get reviewed early.

Foundation and Framing

Foundations get set below the Wisconsin frost line using helical piers or traditional concrete footings depending on soil and load conditions. Framing for composite decks uses ProWood pressure-treated lumber rated for ground contact. Fortress steel framing is available where load, span, or longevity targets call for it. Steel framing pairs well with long-warranty composite boards because the framing service life matches the surface material.

Composite Decking Brands

Available brands include Trex, TimberTech by AZEK, Fiberon, Deckorators, and MoistureShield. Each brand offers multiple product lines at different price points, color ranges, and warranty terms. Selection comes down to budget, color preference, and how the deck gets used.

Deck Styles Built With Composite Decking

Composite decking works across platform, raised, multi-level, freestanding, rooftop, pool, curved, cantilevered, screened, and covered configurations, with privacy screens where wanted. The dimensional stability of capped polymer boards makes composite an especially strong fit for pool decks and curved designs.

Deck Skirting

Skirting options include lattice, solid wood panels, horizontal or vertical boards, stone or brick, faux stone panels, vinyl, and composite. Selection depends on deck height, drainage needs, and the home's exterior finish.

Underdeck Options

Underdeck additions include drainage systems, ceilings, waterproofing, lighting, enclosed storage, ventilation, insulation, and railings. These additions convert the space below a raised composite deck into a usable second outdoor area.

Permit Acquisition

Excel Custom Decks prepares permit-ready drawings and submits them directly to the homeowner's Wisconsin municipality. Permit timelines factor into the project schedule before construction starts.

Composite Decking Brands We Build With

Brand selection on composite decks affects color range, warranty length, board feel, and long-term performance. Excel Custom Decks installs each brand below based on what fits the project.

Trex

Trex decking is the most installed composite product in North America. The capped polymer surface resists fading, staining, and mold across the Transcend, Enhance, and Select lines, with material warranties of up to 50 years.

TimberTech by AZEK

TimberTech decking includes capped polymer and capped composite lines. The AZEK capped polymer line is fully synthetic and recyclable, with strong fade and stain resistance through Wisconsin's heavy seasonal swings.

Fiberon

Fiberon composite offers a range of profiles and color options suited to Wisconsin homes, with strong moisture resistance and long material warranties across the Concordia, Sanctuary, and Good Life lines.

Deckorators

Deckorators composite with mineral-based core options gives structural stability under heavy Wisconsin snow load. The mineral core also reduces thermal expansion and contraction, which matters on decks with long runs.

MoistureShield

MoistureShield composite is engineered to install in ground contact and full moisture exposure, which suits decks built near pools, in shaded yards, or on grade in Wisconsin.

Why Hire a Specialist for Composite Decks

Composite decks reward correct installation with decades of low-maintenance service. The wrong install voids the warranty and shows up later as gaps, fastener pops, and surface damage.

Manufacturer Warranty Compliance

Composite decking warranties from Trex, TimberTech, Fiberon, Deckorators, and MoistureShield include installation requirements covering joist spacing, fastener type, board gapping, and ventilation. Work that falls outside those requirements can void warranty coverage on material defects.

Joist Spacing and Board Span

Composite boards have different span ratings than wood. Joist spacing that works for pressure-treated decking can cause composite boards to bounce, sag, or void warranty coverage. A specialist matches joist spacing to the specific brand and board profile.

Hidden Fastener Systems

Most composite decks use brand-specific hidden fastener systems. Correct fastener selection, slot depth, and spacing affect both the finished surface and the warranty. Wrong fasteners corrode, lose grip, or damage the cap layer.

Thermal Expansion and Gapping

Composite boards expand and contract with temperature swings. Wisconsin’s range from below-zero winters to high-80s summers means board gaps need to be set correctly at the install temperature. Too tight and boards buckle in summer. Too loose and gaps grow ugly in winter.

Permit and Inspection Failures

Unpermitted decks complicate resale and may force demolition or expensive retrofit. Wisconsin municipalities inspect framing and final construction, and work that doesn’t pass requires correction before the project closes.

Frequently Asked Question

How Long Do Composite Decks Last in Wisconsin?

A properly built composite deck typically lasts 25 to 50 years in Wisconsin’s climate, with most major brands carrying material warranties in that same range. Capped polymer products from Trex decking, TimberTech decking, and other major brands hold their color, surface, and structural integrity through Wisconsin freeze-thaw cycles when installed to manufacturer specifications.

Trex Decking or TimberTech Decking: Which Should I Choose?

Both Trex decking and TimberTech decking are top-tier composite options with strong warranties and color ranges that suit Wisconsin homes. Trex has a broader product lineup and longer track record in volume. TimberTech’s AZEK capped polymer line is fully synthetic and recyclable, with deep color options at the premium tier. Excel Custom Decks walks through both brands with samples during design consultation so the homeowner picks based on look and budget rather than label.

Do Composite Decks Get Hot in Direct Sun?

Composite boards run warmer than wood under direct summer sun, with darker colors absorbing more heat than lighter ones. Most major brands now offer heat-mitigating technology in their premium lines that reduces surface temperature significantly. Excel Custom Decks reviews color and brand options against the deck’s sun exposure during design consultation.
