Professional Deck Builders, Design & Installation in Greenfield, WI
Trusted Deck Builders in Greenfield
Greenfield sits directly south of Milwaukee and carries a lot of the same residential character. The homes here are older, the lots run smaller than what you find further out in Waukesha County, and the neighborhoods have been established long enough that mature trees, existing landscaping, and tight site conditions are just part of the reality on most properties.
That context matters when you’re planning a deck. A deck company that doesn’t understand Greenfield's lots, its permitting process, or its mix of architectural styles is going to design something that fights the property rather than works with it.
Brew City Builders has been the trusted deck company for Greenfield homeowners since 2003. Our showroom is in West Allis, a short drive up South 27th Street or Layton Avenue from most Greenfield neighborhoods.

Let's Build a Deck That Works for You
Building a deck involves more decisions than most homeowners expect. Layout, materials, height and grading, railings, stairs, lighting, and how it all ties into the rest of the property. Brew City Builders handles all of it, from the first conversation about what you want the space to do, through design, permitting, construction, and the finishing details that make a deck feel complete.
We work on straightforward deck replacements as well as larger builds that include built-in seating, pergolas, multi-level layouts, or outdoor kitchens. Whatever the scope, our goal is the same: a deck that's structurally solid, fits your property, and holds up to years of actual use.
If you're ready to talk through your project, contact Brew City Builders and we'll help you figure out what it'll take to get there.

Deck Design That Works With Smaller Lots
Smaller lots demand smarter design. In Greenfield, where a backyard might be compact with mature trees already occupying part of it, the design process has to account for what is actually there rather than starting from a blank canvas assumption.
Before we draw anything up, we come to your Greenfield property and spend time understanding the site.
Where are the setback lines? How does grading and drainage affect where the deck can go? Are there root systems near the ledger that need to be considered? How does the deck connect to the inside of the home in a way that feels natural rather than awkward?
Those site-specific questions drive the design. After that initial visit, you come to our West Allis showroom and work with Amy on a custom 3D design session. You will see your exact
Greenfield property with your chosen materials, layout, and railing style from every angle before we break ground. What you see in that rendering is exactly what gets built.
Composite Deck Installation in Greenfield
Composite decking is the most popular choice among Greenfield homeowners who want a deck that performs well through Wisconsin winters without demanding ongoing maintenance every couple of years. As your local deck company, we exclusively use Timbertech Advanced PVC for all composite deck installation projects.
Timbertech Advanced PVC is 100% PVC with no wood fibers, and that distinction matters specifically for Wisconsin's climate:
- Handles freeze-thaw cycles without cracking, warping, or splintering season after season.
- Available in 15 colors covering everything from warm natural wood tones to contemporary designer shades.
- Stays clean with just soap and water, no staining, sealing, or sanding involved.
- UV-resistant capping keeps the color consistent year after year without fading.
You can see every Timbertech color under real lighting at our West Allis showroom before you commit to anything. For a decision you will live with for decades, seeing materials in person rather than on a screen is worth the short drive.
Wood Deck Installation in Greenfield
Composite isn’t the right fit for every Greenfield homeowner. Some people want the warmth, the grain, and the feel of a real wood deck, and that preference is completely valid. For wood deck installation, we use ProWood treated pine, infused with iron to give it a cedar-like appearance with stronger rot resistance than standard treated lumber.
No matter which surface material you choose, every deck we build is framed with KDAT lumber.
Here is why that decision matters more than most people realize:
- Standard pressure treated framing leaves the mill wet and shrinks, warps, and twists as it dries in place over the months after installation.
- That movement causes boards to go uneven, fasteners to work loose, and structural problems to develop years before they should.
- KDAT is kiln dried before it ever arrives on your job site, already dimensionally stable at installation.
- The framing holds its shape, the surface stays level, and the deck performs correctly a decade from now instead of developing sags and soft spots.
That single framing decision is what separates a deck that lasts 40 years from one that needs attention at 10.
Porch Installation in Greenfield
Greenfield's older bungalows, cape cods, and brick ranches have genuine architectural character that a porch needs to respect. A poorly designed porch on one of those homes is visible from the street and does more damage to curb appeal than it adds.
We design every porch around the home it is going on, matching rooflines, trim details, and proportions so the finished result looks original rather than added on.
Porch types we build for Greenfield homeowners:
- Front porches that improve street presence and give the home a proper covered entry.
- Screened porches that make Greenfield summer evenings genuinely enjoyable without the insects.
- Three-season porches that extend livable outdoor space from early spring through late fall.
Every
porch installation in Greenfield includes proper flashing, ledger attachment, and trim work tied into the home's existing structure so it holds up and looks right for the long term.
Commercial Deck Building in Greenfield
Restaurants and businesses along South 27th Street and Layton Avenue compete for customers who have real options nearby. Outdoor seating that looks professional and holds up under daily foot traffic is part of staying competitive in that environment.
We build
commercial decks for Greenfield businesses using heavier structural framing and Timbertech Advanced PVC for the surface. It handles the traffic, needs only occasional cleaning, and never requires the kind of seasonal maintenance that would force you to close off your patio. Our commercial work includes projects for The Harp and Wauwatiki Bar and Grill across southeastern Wisconsin.

See It, Touch It, Compare It in Person
Photos and product pages can only show you so much. They don't tell you how a composite board feels underfoot, how a railing color looks in changing light, or how one finish compares to another side by side. That's what the Brew City Builders showroom is for. Walk through real samples, test different textures and colors, and get straight answers about what holds up best over time and why.
Give us a call at (414) 453-1235 to set up a free consultation. We'll help you narrow down the right materials and start shaping a deck or outdoor living space built around your home, your business, and your long-term plans.
