Professional Deck Builder in Pewaukee, WI

Custom Decks and Porches for Pewaukee Homes
Pewaukee is not your average suburb. Lakefront properties along Pewaukee Lake, larger lots in newer subdivisions, and established neighborhoods closer to the city center all sit within a few miles of each other. That variety means outdoor spaces here need to be designed around the specific property they're going on, not built from a template.
Brew City Builders has been the trusted
deck builder in Pewaukee and the surrounding Waukesha County area since 2003. Our showroom is in West Allis, about 20 minutes east on I-94, and we've been pulling Pewaukee permits and building on properties throughout the area for over two decades.
See Materials in Person Before You Commit
Most homeowners pick materials from a website and regret it once the deck is built. Colors shift under natural light. A railing that looks sharp in a photo feels completely different when you grab it in person.
At our showroom you can:
- Walk through the full Timbertech Advanced PVC color lineup under real lighting.
- Touch and compare Westbury aluminum and Fortress steel railings side by side.
- See examples of Dan's hand-fabricated metalwork to understand what's possible beyond standard catalog options.
Showroom hours:
1900 S 74th St. in West Allis
Monday - Friday: 8:00 AM to 4:00 PM
Saturday and Sunday: Closed

Designed Around Your Pewaukee Property
Pewaukee properties don't all look the same. A lakefront lot with a view worth protecting needs a completely different layout than a subdivision backyard where privacy and entertaining space matter more.
We start every project at your property. We walk the yard, check the slope and drainage, look at how the sun moves through the space during the day, and figure out how the deck connects to the inside of your home in a way that feels natural. That site visit shapes everything from the deck's footprint to where the stairs land to how the whole thing sits against the home's exterior.

Composite Deck Installation in Pewaukee
Here's what that means for Pewaukee specifically:
- Zero moisture absorption, which matters on lakefront and lakeview properties where humidity runs higher.
- Handles Wisconsin freeze-thaw cycles without cracking, warping, or splintering.
- 15 color options from natural wood tones to contemporary grays and warmer shades.
- Cleans up with soap and water, nothing else, no schedule to track.
It's the most low-maintenance surface we've worked with in over 20 years of building in Wisconsin, and it holds up better in this climate than anything else we've tested.

Wood Deck Installation in Pewaukee
Composite isn't for everyone. Some homeowners want the real thing, the grain, the warmth, the way a wood deck feels underfoot on a summer evening.
For wood deck installation, we use ProWood treated pine. It's infused with iron for a cedar-like appearance and stronger rot resistance than standard treated lumber. Properly installed with the right flashing and fasteners, it holds up for decades.
One thing that's true on every deck we build, composite or wood: we frame with KDAT lumber. Standard pressure treated framing arrives wet on site and shrinks as it dries, which is what causes boards to go uneven and decks to develop sags early. KDAT is kiln dried before delivery. It's stable from the day we install it, and it stays that way.
Porch Installation in Pewaukee
Pewaukee homeowners spend real time outdoors. A
porch installation extends how much of the year that's actually possible, and gives you somewhere comfortable to be when the weather doesn't cooperate with an open deck.
We build three main porch types:
- Front porches that add a covered entry and improve curb appeal without looking tacked on.
- Screened porches that solve the summer bug problem without giving up the outdoor feel, especially useful on evenings near the lake when insects are at their worst.
- Three-season porches with operable windows that give you a usable indoor-outdoor room from early spring through late fall.
Every porch ties into your home's existing structure with proper ledger attachment, flashing, and trim details that match what's already there. The goal is for it to look like it was always part of the original build.

Pergolas and Gazebos in Pewaukee
A pergola or gazebo adds definition to an outdoor space in a way that an open deck simply can't. For Pewaukee properties where the yard is a real part of how the home is used, having a defined area with some overhead structure changes how the whole space feels.
Here's the difference between the two:
A
pergola has open beams and rafters that provide partial shade while keeping the open-air feel. It works especially well over a dining or lounge zone, and on lakefront properties it frames the view without blocking it.
A
gazebo is fully roofed and freestanding. It's a dedicated outdoor room separate from the main deck, which works well on larger lots where there's room to spread activities across the property.
We build all three to fit the overall property rather than just dropping a structure in the yard.
Commercial Deck Building in Pewaukee
Pewaukee restaurants and businesses rely on outdoor seating to stay competitive. A patio that can't handle daily use or needs to close every season for maintenance is more of a problem than it's worth.
Here's what goes into every commercial deck we build:
- Heavy structural framing sized for real commercial occupancy loads.
- Timbertech Advanced PVC on every surface because it handles traffic, spills, and weather without sanding or sealing.
- Layouts built around how staff moves and how customers flow through the space
- Railing systems that meet commercial code.
Our commercial project history includes The Harp and Wauwatiki Bar and Grill across southeastern Wisconsin. And if your existing
commercial deck needs repair rather than full replacement, we'll give you a straight read on which makes more sense before recommending anything.
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.
