01 / 02

Welding and fabrication, in-house.

A lot of what makes an outdoor space feel custom is the metalwork detail. Steel pergola brackets and posts, decorative screens that add privacy without closing in a patio, steel planters, and fire features all come from the same shop that builds your gates and railings.

Because we fabricate it ourselves, the detail and finish match the rest of your project rather than being sourced from three different suppliers.

02 / 02

Built to your drawings or scope.

If you have a drawing, a photo, or just a clear idea, we can quote and fabricate it. We work from a defined scope so the price is fixed and the result matches what you expected.

We can also fabricate brackets, screens, railings, and accent metalwork to spec for a project another contractor is building. Send the drawings and we will tell you honestly whether it is a fit.

How we work

Four predictable steps. Same for every project.

  • 1

    Consultation

    We meet at your home, walk the backyard, and listen to how you actually want to use the space. A real conversation about the project, with no pressure and no hard sell.

  • 2

    Design and scope planning

    We sketch the layout in place, talk through structure and elevation, and define a clear written scope so everyone knows exactly what is being built.

  • 3

    Material selections

    We bring real material samples to your home and compare them in your own light. Composite versus cedar, roof options, railings, and finishes, chosen with you, not guessed.

  • 4

    HOA and permit coordination

    When your project needs HOA approval or a city permit, we prepare the submission package and handle the back-and-forth so you are not chasing paperwork.

  • 5

    Build and progress updates

    A tight, trusted crew builds the project on a written schedule. You get regular progress updates, so you always know what is happening and what comes next.

  • 6

    Final walkthrough

    We walk the finished project with you, complete a punch list together, and hand over every manufacturer warranty registered in your name.
