Existing weathered wood deck and stairs before replacement in Renton

The Challenge

The existing wood deck showed significant age and deterioration, including worn decking, stairs, and railing. Rather than replacing only the visible surface, the project required structural work to create a stronger foundation for the new decking and railing.

Where existing framing remained serviceable, including floor joists over the garage, it was retained rather than unnecessarily replaced.

A Structural Deck Replacement

The existing deck was removed and rebuilt where needed while maintaining the general layout of the original structure.

The project included new pressure-treated framing, improved structural connections and moisture protection, rebuilt stairs, Trex Select composite decking, AZEK trim, and Trex Signature aluminum railing.

Serviceable framing over the garage was retained where appropriate, while other components were replaced to create a stronger, lower-maintenance deck built for long-term performance.

Why Trex Select Composite Decking?

For this project, the homeowners selected Trex Select composite decking in Saddle, combining a warm wood-inspired appearance with lower maintenance than traditional wood decking.

The deck features a two-board perimeter trim and mid-span detail for a more finished, custom appearance.

Benefits include:

  • Low-maintenance surface

  • No sanding or staining required

  • Resistance to moisture and everyday weather exposure

  • Splinter-free decking

  • Hidden fasteners across the main deck surface

  • Long-lasting color and durability

Composite decking is a practical choice for Renton's wet Pacific Northwest climate, where traditional wood decking requires more ongoing maintenance.

Trex Signature Aluminum Railing

The new white Trex Signature aluminum railing gives the rebuilt deck and stairs a clean, finished appearance while providing a durable, low-maintenance railing system.

Advantages include:

  • Powder-coated aluminum construction

  • Rust-resistant finish

  • Minimal maintenance

  • Strong, code-compliant design

  • Clean contrast with the Saddle composite decking

An additional railing section was installed along the existing concrete steps to create a more continuous and secure transition from the deck to the lower yard.

The Petra Decks Approach

Every Petra Decks project begins with the structure. Before installing new decking, we evaluate the framing, supports, stairs, ledger connection, and other structural components to determine what can remain and what should be replaced.

For this Renton project, serviceable framing was retained where appropriate while deteriorated components were replaced and upgraded for long-term performance.
