Castle Rock is a small city along the Cowlitz River, historically a river and timber town and today known as a gateway to Mount St. Helens. Its housing stock is modest and largely older, with early-to-mid-1900s homes near downtown that often need wiring, insulation, and window updates alongside kitchen and bath work.

From Downtown Castle Rock to the rest of Castle Rock, we match every covered decks & pergolas project to the age, construction, and condition of your specific home rather than a one-size-fits-all spec.

• Roofed and covered deck structures
• Open and louvered pergolas
• Rain-shedding roofing tied into the existing roofline

• Posts and footings engineered for local soils and drainage
• Gutter and drainage tie-ins on covered structures
• Wind-rated structural connections for Gorge-exposed sites
• Privacy screens and shade panels
• Prep for TV, heaters, and outdoor kitchens

1. 01

   Design Consultation

   We look at your existing or planned deck, your site's rain and wind exposure, and how you want to use the space — full cover, filtered shade, or a breezy pergola — and design a structure that ties into the home.

2. 02

   Engineering & Permitting

   Covered structures add roof load and often attach to the house, so they require engineering and permits. We prepare the drawings and handle approvals for your jurisdiction.

3. 03

   Footings & Framing

   Posts are set on engineered footings sized for your soil and drainage and tied in with properly flashed connections, then the frame and roof or pergola structure are built and integrated with the existing roofline and gutters.

4. 04

   Cover & Finish

   Roofing, louvers, or shade panels are installed along with any lighting, fans, and outlets. We finish the ceiling and details, then complete a final inspection.

Typical timeline: Typically 1 – 4 weeks. We provide a written schedule after assessing your Castle Rock home.
