Add Shade, Style, and Structure to Your Outdoor Space

Pergolas, Gazebos & Arbors in Wisconsin

Structures That Frame and Elevate Outdoor Living

Custom Pergolas, Gazebos, and Arbors for Any Setting

Each structure we build is tailored to your space and goals—shade, privacy, seating, or garden entry. We design pergolas for decks and patios, gazebos for freestanding lounging areas, and arbors for walkways or fencing transitions. Whether you want a simple post-and-beam structure or something ornate and architectural, we’ll help you choose the right size, materials, and placement.

Crafted to Withstand Wisconsin’s Weather

Strong, Safe, and Styled for the Midwest

Every pergola, gazebo, and arbor we build is reinforced to hold up under Wisconsin’s seasonal stresses—from snow loads to wind gusts. We use weather-rated wood and hardware, and anchor each structure securely for long-term durability. You’ll get more than a decorative accent—you’ll get a functional feature that adds real value to your property

  • Freestanding or attached options available

  • Built with cedar, pressure-treated wood, or composite

  • Custom finishes, trim, and roofing add visual impact

From Practical Shade to Decorative Focal Points

Structures That Define Outdoor Space and Function

A pergola or gazebo does more than add beauty—it creates a sense of place. Use it to anchor a seating area, define a dining space, or provide relief from direct sunlight. Arbors offer charming transitions between areas of your yard or serve as entry points to fenced zones or gardens. These features work as architectural accents and functional upgrades, with plenty of options to fit any aesthetic.

We Build for Style and Stability

Built Right—From Posts to Rafters to Roofs

We don’t just build pretty structures—we build strong ones. Every post is set deep and anchored properly. Rafters are spaced for strength and symmetry. For gazebos, we offer open or screened designs, optional benches, and shingled or metal roofs. Pergolas can include angled slats, retractable canopies, or lighting. With decades of experience, we ensure everything looks clean and lasts through Wisconsin’s climate.

One-Stop Design and Build

We Handle Everything From Layout to Final Touches

You don’t need to juggle contractors or guess on materials. We design each structure in-house and build it with our own crews. From layout sketches to footing depth and finish carpentry, we handle every detail. Want to match your home’s trim or coordinate with your deck stain? We’ll help you pick the right options. Our goal is a structure that fits perfectly and performs beautifully.

Pergola & Gazebo FAQs

What Wisconsin Property Owners Ask Before They Build

Here are the answers to common questions about pergolas, gazebos, and arbor installations across Wisconsin.

Question 1: Do pergolas provide full shade?

Pergolas offer partial shade. We can add angled rafters, retractable canopies, or climbing vines for more coverage.

Question 2: Will my gazebo need a building permit?

Most permanent structures require permits. We handle all permitting and ensure code compliance.

Question 3: Can I add a pergola to my existing deck?

Yes. We’ll evaluate the framing and footings to ensure safe attachment or support post placement.

Question 4: What maintenance is required for wood pergolas?

Cedar and pressure-treated wood need occasional cleaning and sealing. Composite options require less upkeep.
