Deck Builders in Franklin, WI

Decks and Porches Built For Your Franklin Home
Franklin is one of the larger cities in Milwaukee County by land area, and that size shows up in the properties here. Generous lot sizes, newer construction in subdivisions along Ryan Road and Drexel Avenue, and a residential character that feels more spread out than most communities this close to Milwaukee. Homeowners in Franklin tend to invest seriously in their properties, and outdoor spaces are a big part of that.
Brew City Builders has been building custom decks and outdoor living spaces in Franklin since 2003. We are based in West Allis, about 15 minutes north, and we have pulled Franklin permits and built on properties across the city for over two decades.

Start at the Showroom
Before anything gets decided, come see the materials in person. It makes a bigger difference than most people expect.
Colors look completely different on a screen than they do under real lighting next to your chosen railing system. A railing finish you think you love online might feel cheap in person. One you dismissed in a photo might be exactly right when you touch it.
At our showroom you can:
- Walk through every Timbertech Advanced PVC color under real lighting.
- Compare Westbury aluminum and Fortress steel railings side by side.
- Look at Dan's hand-fabricated metalwork to see what's possible outside a standard catalog.
Showroom hours:
1900 S 74th St. in West Allis
Monday - Friday: 8:00 AM to 4:00 PM
Saturday and Sunday: Closed

Built Around Your Property, Not a Template
Franklin's generous lot sizes mean there is usually real opportunity to work with on any given project. But opportunity and a good design are not the same thing. A deck that does not account for how the yard drains, where the afternoon sun hits, or how traffic flows between the inside of the home and the outdoor space is going to frustrate you regardless of how good the materials are.
Every project we take on in Franklin starts with a visit to your property. We walk the yard, look at the grade, note any drainage considerations, check the setback requirements for your specific lot, and have a real conversation about how you plan to use the space day to day. The design comes out of that process, not out of a folder of pre-drawn plans. Contact us today to get that conversation started.

Composite Deck Builder in Franklin
Here’s how that pays off through a Milwaukee County winter:
- Stands up to freeze-thaw swings without splitting, cupping, or splintering.
- 15 color options, from classic browns to sleek, contemporary grays.
- Cleans up with basic soap and water, so there’s no staining, sealing, or sanding.
- UV resistance keeps the color from fading under years of summer sun.
Wood decks around Franklin usually need a new coat of stain or sealer every couple of years to stay protected. Timbertech eliminates that routine completely and often holds up better than wood in the conditions Wisconsin throws at it.

Wood Deck Installation
Some Franklin homeowners simply prefer real wood, and there’s a lot to like about it. Nothing quite matches its natural grain and feel underfoot. For clients who go that route, we build with ProWood treated pine.
ProWood goes through an iron-infused treatment that gives it a cedar-like color and better protection against rot than typical treated lumber. Paired with proper flashing and quality fasteners, it delivers decades of service along with the classic wood character many homeowners want.
No matter which decking material you pick, we frame every deck with KDAT lumber:
- Typical treated framing is delivered wet and keeps shrinking after it’s installed.
- As it dries, boards shift, fasteners loosen, and the deck can start to sag.
- KDAT is kiln dried in advance, so it’s already stable when it goes in.
- Your deck stays solid and level for the long haul.
The framing is the part of a deck you never see, but it decides whether you get 40 years out of it or start making repairs after 10.
Porch Installation
Franklin homes tend to have strong street presence, and a well-designed porch can make that even better. Whether it is a covered front entry that changes how the home looks from the road or an enclosed outdoor room that adds functional space on the back of the house, a porch does something a deck cannot. It gives you somewhere to be outdoors regardless of what the weather is doing.
Porch types we build for Franklin homeowners:
- Front porches that create a defined covered entry and improve curb appeal in a way that reads well from the street.
- Screened porches that let you enjoy Franklin's summer evenings without the mosquitoes that make open-air sitting uncomfortable after sundown.
- Three-season porches that add a genuine extra room to the home, usable from early spring through late fall with operable windows that adapt to the temperature.
We tie every
porch installation into the home's existing roofline and exterior with proper ledger work, correct flashing, and trim details that make the new addition look like it was part of the original design.

Pergolas and Gazebos in Franklin
Franklin's larger lots give homeowners the room to do more with their outdoor spaces than a single deck footprint allows. A pergola or gazebo takes advantage of that room and adds a layer of function and character that an open platform alone cannot provide.
A pergola placed over a dining or entertaining area on the deck creates definition overhead without fully enclosing the space. It gives you a natural structure for outdoor lighting, a ceiling fan, or climbing plants, and it makes the area underneath feel intentional rather than exposed. For Franklin properties where the backyard stretches far enough to justify it, a separate pergola zone away from the main deck can function as a distinct outdoor room for a different activity.
A
gazebo
goes further with a fully roofed freestanding structure that stands on its own in the yard. It works especially well on larger Franklin properties where there is space to give different areas of the yard their own purpose.
Arbors are the smaller option, typically framing a garden entry or walkway, that add architectural interest without a major commitment.
Commercial Decks in Franklin
Franklin has a growing commercial presence along its main corridors, and restaurants and businesses here need outdoor spaces that work hard without requiring constant attention. A commercial deck that holds up under real daily traffic without seasonal maintenance closures is an asset. One that does not is a liability.
What every commercial deck build in Franklin includes:
- Seating and dining layouts designed around how customers and staff move through the space.
- ADA accessible transitions and routes integrated into the design from the start.
- Commercial-grade structural framing heavier than what a residential build requires.
- Stair and railing systems that meet Franklin's commercial code requirements.
- High-traffic surface materials that do not break down under sustained daily use.
Timbertech Advanced PVC goes on the surface of every commercial deck we build. Our commercial project history includes The Harp and Wauwatiki Bar and Grill across southeastern Wisconsin, and we bring the same standard to every commercial project regardless of size.
Beautiful Custom Railings and Metalwork
A railing does more than keep people safe. It frames the entire deck and shapes the first impression anyone gets when they step outside. The right system makes a Franklin outdoor space look finished and intentional, while the wrong one can drag down an otherwise great build.
We offer three railing options, depending on the look you want:
- Westbury aluminum won’t rust, never needs maintenance, and comes in a range of colors to match your home’s exterior. Its clean, simple profile meets code and fits naturally with everything from traditional to modern homes.
- Fortress steel has a heavier, more substantial presence than aluminum, with styles that run from sleek contemporary to classic. The powder-coated finish stands up to years of Wisconsin weather without any ongoing upkeep.
- Dan’s custom fabricated steel is designed and built by hand for your project alone. Think family crests set into railing panels, geometric privacy screens, or patterns drawn from nature: metalwork that becomes a centerpiece of the property instead of something that fades into the background.
