Deck Builder in St. Francis, WI

Custom Decks Built for Lakefront Living
St. Francis is one of Milwaukee County's smallest cities by land area, but what it lacks in size it makes up for in character. Sitting right along Lake Michigan between Cudahy and Milwaukee's south side, the city has a tight residential feel with older homes on compact lots, tree-lined streets, and a waterfront presence that shapes how people think about outdoor living here. Being this close to the lake means outdoor spaces matter, and they need to be designed with that environment in mind.
Brew City Builders has been the expert deck builder in St. Francis and the surrounding Milwaukee County area since 2003. We are based in West Allis, about 15 minutes west, and we know the city well.

Come See the Materials In Person
St. Francis properties sit close to Lake Michigan, which means more humidity, more weather exposure, and more reason to get the material decision right the first time. Choosing a decking color or railing finish from a photo online does not tell you how it holds up in a lakefront environment or how it actually looks in person against your home's exterior.
At our showroom, you can walk through the full Timbertech Advanced PVC color lineup under real lighting, compare Westbury aluminum and Fortress steel railings by touch as much as by sight, and look through Dan's custom fabricated metalwork samples to see what a railing can look like when it is designed specifically for a project rather than pulled off a shelf.

Designs That Fit St. Francis Lots
St. Francis lots run smaller than what you find in communities further out from the city, and that reality has to drive the design. A deck layout that works on a large Franklin subdivision lot would overpower a St. Francis property and leave no room for the yard to breathe. Every square foot here has to earn its place.
We come to your St. Francis property before drawing anything up. We look at how the lot sits, where the usable outdoor space actually is, how close neighboring structures are, and how the deck connects to the interior of the home in a way that feels natural rather than tacked on. Smart design on a smaller lot often produces a more satisfying result than a larger footprint on a property that could have accommodated more.

Composite Deck
Here’s why that matters so close to Lake Michigan:
- Resists cracking and warping through damp lakefront air and hard winter freezes.
- 15 colors available, including natural wood looks and modern gray finishes.
- Needs nothing more than an occasional rinse with soap and water, so you’ll never stain, seal, or sand.
- UV protection keeps the color rich instead of letting it bleach out over time.
A wood deck in St. Francis can need restaining every two or three years to fight off moisture and sun. Timbertech takes that chore off your list for good while outlasting wood where it counts.

Wood Deck Installation
Composite has its advantages, but some St. Francis homeowners won’t settle for anything other than real wood. If the look and character of natural lumber is what you want, we build with ProWood treated pine.
ProWood’s iron-infused treatment gives it a warm, cedar-like tone and stronger rot resistance than standard treated boards. Installed with proper flashing and quality fasteners, it lasts for decades and keeps the genuine wood appeal that makes it such a popular choice.
Whether your deck surface is composite or wood, KDAT lumber forms the frame underneath:
- Conventional treated lumber arrives soaked and shrinks as it dries in place.
- That shrinkage throws boards out of line and leads to early sagging.
- KDAT is kiln dried before it ever ships, so it doesn’t move after installation.
- The result is a frame that keeps your deck flat and sturdy for decades.
A great-looking deck only lasts as long as the structure holding it up, and
KDAT framing is what gives a deck 40 years instead of 10.
Porch Installation in St. Francis
The older homes in St. Francis were built in an era when front porches were standard, not optional. A lot of those original porches are gone now, replaced by simple stoops, and putting one back changes how the home presents to the street in a way that almost nothing else can. For homes on the back side of the city with lake views or lake breezes, an enclosed porch extends how much of the year you can actually enjoy that location.
Porch types we build for St. Francis homeowners:
- Front porches that restore the covered entry the home was designed to have and improve curb appeal from the street.
- Screened porches that let you take advantage of the lake breeze on summer evenings without dealing with the insects that come with it.
- Three-season porches with operable windows that capture the best of the St. Francis waterfront location from early spring through late fall.

Pergolas and Gazebos in St. Francis
On a compact St. Francis lot, a pergola does something especially useful. It creates a sense of overhead enclosure and defined outdoor space without adding square footage or reducing yard room the way a fully roofed structure would. That balance matters a lot on smaller properties where every foot of yard serves a purpose.
A pergola positioned over a dining area or main seating zone gives the space definition overhead, a structure for lighting and ceiling fans, and a visual anchor that makes the outdoor area feel considered rather than improvised. On a property near the lake, the open beam structure lets the breeze through while still providing partial shade during the hours when the sun is most direct.
A
gazebo is the right choice when a dedicated freestanding outdoor room makes sense for the property. It provides full overhead coverage in a structure that stands independently from the deck, and it works well when there is enough yard to give it space without crowding everything together.
Arbors are smaller still, used most often over a garden entry or gate, and add architectural character without taking up meaningful space
Commercial Deck Builder in St. Francis
St. Francis has restaurants and businesses that depend on outdoor seating to stay competitive with neighboring communities along the lakefront corridor. A commercial deck installed here needs to handle daily use, hold up through lake-adjacent weather conditions, and stay off the maintenance schedule as much as possible.
What every commercial deck build can include:
- Seating and dining layouts that work around actual customer and staff movement patterns.
- ADA accessible routes and transitions designed into the layout from the start.
- Heavier structural framing than a residential project requires to handle commercial occupancy loads.
- Stair and railing systems that meet commercial code.
- Surface materials rated for high daily traffic without seasonal maintenance requirements.
Timbertech Advanced PVC is the
surface material on every commercial deck we build, and it is especially well suited to the lake-adjacent conditions St. Francis businesses deal with. It handles moisture, foot traffic, and weather without the seasonal maintenance that takes a commercial patio offline when you can least afford it.
Custom Railings and Metalwork
A railing system does two things. It keeps people safe, and it finishes the visual design of the whole outdoor space.
WE OFFER THREE DIRECTIONS:
- Westbury aluminum
is rust-proof, needs no painting or upkeep, and comes in multiple colors. It works with almost any home style and meets Wisconsin code without looking heavy or industrial.
- Fortress steel
has more visual mass than aluminum and comes in styles from modern to traditional. The powder-coated finish holds up through outdoor conditions without ongoing maintenance.
- Dan's custom fabricated steel is in a different category entirely. These are hand-built railings designed specifically for your project. Family crests, geometric screens, one-of-a-kind patterns that become a signature feature of the property. No catalog, no templates, built specifically for your deck.
