that ages well.

Patios are where your house spills outside. We pour slabs with clean lines, honest drainage, and a finish that still looks sharp after a decade of Pacific Northwest weather.

The pitch

A patio isn’t a slab.
It’s a room.

We design patios to live with — proper sun, proper drainage, proper flow from the back door. Broom finish for barefoot weekends. Sawcut tile pattern for the clean modern look. Stamped for traditional. We'll walk the site with you and tell you what'll work.

02 · What we do

The full range.

Broom & smooth finish

The timeless backyard slab. Warm under bare feet. Simple, honest, permanent.

Saw-cut tile look

Grid of clean saw cuts create a large-format tile aesthetic without the grout-line failures.

Stamped & decorative

Slate, stone, wood-plank patterns. Integrally colored. Sealed for long-term UV and stain resistance.

Patio + walkway combos

We pour the patio, the walkway, and the connecting stairs as one integrated system. No mismatched seams.

04 · Our standards

Non-negotiable.

  • 01

    Drainage first. We grade so water leaves the house — not pools next to it.

  • 02

    2% minimum fall on every slab. No exceptions, no flat patios.

  • 03

    Expansion joints where the patio meets the house — so foundation movement doesn't crack the slab.

  • 04

    Proper sand bed or crushed rock base compacted in lifts. No shortcuts under the pour.

  • 05

    Final surface sealed before we call it done. Prevents staining and spalling.
