New Deck Construction
Building a new deck is an opportunity to create an outdoor space that complements your home and lifestyle.
Every deck is custom designed around your property, intended use, and long-term goals. Whether you envision a simple backyard retreat or a large multi-level entertaining space, we focus on structural integrity first, followed by craftsmanship and attention to detail.
Our custom deck construction includes:
Ground-level decks
Attached decks
Elevated decks
Multi-level decks
Covered decks
Wraparound decks
Pool and hot tub decks
Outdoor living spaces
Complete Deck Replacement
Many older decks reach a point where repairs are no longer the safest or most cost-effective solution.
If the framing has deteriorated, the deck no longer meets current building standards, or the structure has reached the end of its service life, a complete deck replacement provides the best long-term value.
Our replacement process includes:
Complete demolition and removal
Structural framing inspection
New code-compliant framing
New footings when required
New stairs
Modern guardrails
Premium composite, PVC, or cedar decking installation
Rather than covering existing problems, we rebuild your deck from the structure up to create a safe outdoor space designed to serve your family for decades.
Decking Installation & Replacement
Not every deck requires a complete rebuild. If the existing framing passes our structural inspection, replacing the decking can transform the appearance and performance of your deck without rebuilding the entire structure.
When the structural framing remains sound, replacing worn decking can dramatically improve the appearance, comfort, and lifespan of your outdoor living space.
Petra Decks installs premium decking systems including:
Composite decking
PVC decking
Cedar decking
Hidden fastener systems
Picture-frame borders
Fascia boards
Matching stair treads
Deck skirting
We'll inspect the existing framing before recommending decking replacement to ensure your investment is built on a safe and durable foundation.
Custom Deck Expansions and Layout Changes
Your outdoor living needs can change over time. If your current deck feels too small or no longer fits the way you use it, expanding or reconfiguring the layout can dramatically improve its functionality and value.
Petra Decks builds custom deck expansions that integrate seamlessly with your existing home and structure. Whether you're creating more space for outdoor dining, entertaining, a hot tub, or simply improving the flow between your home and backyard, we build every addition with long-term structural performance in mind.
Many deck expansions require new footings, framing, stairs, railings, permits, and engineering to ensure the new construction performs as one complete, code-compliant structure. Our structural-first approach ensures your expanded deck looks like it was always part of your home.
Structural-First Deck Construction
A beautiful deck begins with a solid structure.
Every Petra Decks project is built using proper framing techniques, quality hardware, and current Washington building codes.
Our construction process focuses on:
Proper beam sizing
Correct joist spacing
Secure ledger attachment
Durable flashing
Proper drainage
High-quality structural connectors
Because what you don't see is just as important as the finished surface.
We assist with permits, coordinate inspections, and build every deck to current Washington building code requirements, ensuring a safe and code-compliant project from start to finish.

Frequently Asked Questions
How do I know if my deck should be replaced instead of repaired?
If the structural framing, footings, or support posts are deteriorated, no longer meet current building standards, or have reached the end of their service life, a complete deck replacement is often the safest and most cost-effective long-term solution. Every project begins with a structural evaluation so we can recommend the best option for your home.
Can you replace only the decking boards?
Yes. If the existing framing is structurally sound, we can replace the decking, stairs, fascia, and railings without rebuilding the entire deck. We'll inspect the structure first to ensure it's safe and suitable for new decking.
What decking materials do you install?
We install premium composite, PVC, and cedar decking from trusted manufacturers. We'll help you compare colors, performance, maintenance requirements, and budget to select the material that best fits your home and lifestyle.
Why do so many homeowners choose composite decking?
Composite decking is one of our most popular options because it offers exceptional durability, low maintenance, fade resistance, and long-lasting beauty. It's an excellent choice for homeowners who want lasting performance with minimal upkeep.
Can you expand my existing deck?
Yes. If you'd like more space for outdoor dining, entertaining, or relaxing, we can design and build a custom deck expansion. Many expansion projects require new footings, framing, stairs, and railings to create a seamless addition that looks and performs like it was always part of your home.
Do you build covered decks?
Yes. We design and build custom covered decks that provide shade, weather protection, and year-round outdoor living while complementing your home's architecture and outdoor space.
How long does a typical deck construction or replacement project take?
Most custom deck construction and complete deck replacement projects take one to three weeks, depending on the size of the deck, permitting requirements, weather conditions, and overall project complexity. Before construction begins, we'll provide a realistic timeline and keep you informed throughout every stage of the project.
