Railing Systems


The right railing system enhances safety, complements your deck design, and adds visual interest.

Westbury Aluminum Railing

Westbury aluminum railing systems offer sleek, modern looks with exceptional durability. Aluminum won't rust, rot, or corrode, making it ideal for Wisconsin weather.

Benefits of Aluminum Railing

  • Low maintenance with no painting or staining
  • Multiple color options to match your home
  • Clean lines that work with any architectural style
  • Strong and code compliant
  • Open, airy feel that doesn't block views



Westbury railings meet all safety requirements while maintaining attractive design. They're a smart choice for homeowners who want quality railings without ongoing maintenance hassles.

Fortress Railing Systems

Fortress steel railing systems provide versatile design options with superior strength. Available in various styles from traditional to modern, Fortress railings combine steel durability with attractive powder coated finishes that resist fading and weathering.

Custom Fabricated Metal Railings

For clients who want something truly unique, Dan creates custom fabricated steel railings. These aren't just railings. They're works of art.


Custom options include:

  • Family crests incorporated into railing panels
  • Geometric patterns and nature inspired designs
  • Decorative screens and privacy panels
  • One of a kind designs specific to your space

KDAT Framing Lumber


Regardless of which decking material you choose, we build the structure underneath with KDAT (Kiln Dried After Treatment) framing lumber. This is a significant upgrade over standard pressure treated framing.


Traditional pressure treated lumber is wet when it leaves the treatment facility. As it dries over time, it shrinks, warps, and twists. This causes deck boards to become uneven, fasteners to loosen, and structural problems to develop.

KDAT lumber is kiln dried after treatment. That means it's already dimensionally stable when we build with it. It won't shrink or warp significantly after installation.


The results you get:


  • Straighter framing that stays level
  • Tighter joints that don't separate
  • Fewer long term problems
  • A more durable deck structure


The dimensional stability of KDAT lumber means fewer callbacks and a deck that performs better for years. It costs slightly more than standard treated lumber, but the improved performance is worth it. We use KDAT framing on every deck we build because we've seen the difference it makes.

Timbertech Advanced PVC Decking


For low maintenance decks, we exclusively use Timbertech Advanced PVC. This is our top recommendation.

Why We Prefer PVC Decking

  • 100% PVC with no wood fibers
  • Won't absorb water or support mold growth
  • Excellent fade resistance
  • Stays cooler on hot days than many composites
  • Available in multiple designer colors including Brownstone
  • Minimal maintenance needed


It just needs occasional cleaning with soap and water. No staining, no sealing, no sanding. We've worked with many decking materials over 20 years, and Timbertech Advanced PVC consistently outperforms other products in Wisconsin's climate.
