Trusted Deck Builders in West Allis


A deck in West Allis has to do more than look good on installation day. It has to fit the home, work with the size of the lot, handle Wisconsin weather, and feel like it belongs with the rest of the property. Brew City Builders has been building decks and porches in West Allis since 2003, with a local showroom where homeowners can compare materials, railing options, and design ideas before making decisions.


We know the difference between building for a tight backyard near Greenfield Avenue, a larger lot off National Avenue, or a home near State Fair Park where the deck needs to blend with the home’s existing character. Every property has its own layout, grade, access points, and design challenges, so we don’t build from a one-size-fits-all plan.


From composite deck installation and traditional wood decks to porches, railings, stairs, and complete outdoor living upgrades, our team designs each project around how you actually want to use the space.

Your deck should feel like it was planned for your home, not picked from a standard layout. Brew City Builders helps West Allis homeowners choose the right design, materials, railings, and finishing details so the finished space looks good and works for real life. Whether you’re replacing an old deck or starting fresh with a completely new outdoor space, our team can guide you from the first idea to the final build.

Composite Deck Installation in West Allis


A composite deck is the most popular choice for West Allis homeowners who want a great-looking outdoor space without a lot of ongoing maintenance. As your local deck company, we exclusively use Timbertech Advanced PVC for all composite deck projects.

Timbertech Advanced PVC is 100% PVC with no wood fibers.


Here is what that means for you:


  • No rotting, cracking, warping, or splintering through Wisconsin winters
  • Available in 15 colors including natural wood tones and designer shades
  • Stays clean with just soap and water a couple of times a year
  • No staining, no sealing, no sanding, ever


Because our showroom is right here in West Allis, you can walk in any weekday and see every Timbertech color under real lighting before you decide. What you see in the showroom is exactly what you get on your deck.

Wood Deck Installation in West Allis


If you prefer the look and feel of a traditional wood deck, we build those too. We use ProWood treated pine for our wood deck installation projects. ProWood is infused with iron to give it a cedar-like appearance with stronger rot resistance than standard treated lumber.



When installed with proper flashing and quality fasteners, a ProWood deck lasts for decades. It gives you the natural wood look a lot of West Allis homeowners want without sacrificing durability or lifespan.

Regardless of which decking material you choose, every deck we build gets framed with KDAT lumber.


Here is why that matters:


  • Standard pressure treated framing is wet when it leaves the treatment facility
  • As it dries over time, it shrinks, warps, and twists
  • That causes boards to become uneven, fasteners to loosen, and structural problems to develop
  • KDAT is kiln dried before it arrives on your job site, so it is already stable when we install it


The result is a deck that stays straight, stays level, and holds up far longer than one built with standard treated framing. It is one of the biggest differences between a deck that sags in 10 years and one that is still solid at 40.

Custom Railings and Metalwork


Railings finish a deck and pull the whole design together.


We offer 3 options depending on what you're looking for:

  • Westbury aluminum railings are low maintenance, rust-proof, and come in multiple colors to match your home


  • Fortress steel railing systems offer a range of styles from modern to traditional with powder-coated finishes built for outdoor use



  • Dan's custom fabricated steel railings are built by hand for your specific project, family crests, geometric patterns, decorative screens, and one-of-a-kind designs you will not find anywhere else

Commercial Deck Building

We build commercial decks for restaurants, bars, and businesses across West Allis and southeastern Wisconsin. Outdoor seating adds capacity and draws customers in, and it needs to hold up under heavy daily use.



Our commercial deck installation projects use heavier framing and Timbertech Advanced PVC for the surface. It handles high foot traffic, needs only occasional cleaning, and never requires sanding or sealing. Less maintenance means less disruption to your business.
