Expert Advice for Seattle Homeowners
Composite vs. Cedar: Making the Right Choice
Choosing the right material is the most important decision you will make for your new outdoor living space. As a leading Custom Deck Builder Seattle, we often get asked: “Should I choose wood or composite?”
Composite Decking (Trex/TimberTech) is the most popular choice for Seattle homes. Why? It is engineered to resist moisture, meaning it won’t rot, warp, or attract termites. It requires zero staining—just a simple wash with soap and water. While the upfront cost is higher, it pays for itself in maintenance savings over time.
Natural Cedar offers a classic, aromatic beauty that synthetic materials can’t fully replicate. It is a traditional choice for the Pacific Northwest. However, to keep it looking great in our rainy weather, it requires regular staining and sealing every 2-3 years.
At Trust Builds, we walk you through the pros and cons of each to ensure you get the perfect deck for your budget and maintenance preference.

Frequently Asked Questions
Do I need a permit to build a deck in Seattle?
In most cases, yes. Any deck more than 18 inches off the ground typically requires a permit. As your Custom Deck Builder Seattle, Trust Builds handles all drawings, submissions, and inspections with the city so you don't have to worry about compliance.
How much does a new deck cost?
The cost varies widely based on size, materials (Composite is more expensive than wood), and terrain (slope vs. flat). We provide a detailed, itemized estimate after our site visit so you know exactly where your budget is going.
How long does it take to build a custom deck?
Once permits are approved, the actual construction typically takes 1 to 3 weeks, depending on complexity and weather. We work efficiently to minimize disruption to your home life.
Can you build a deck in the winter/rain?
Yes! We build year-round. While heavy rain might cause minor delays, our crew is equipped to work in Seattle weather. Winter is actually a great time to build so your deck is ready for the first sunny day of spring.
What brand of composite decking do you recommend?
We prefer Trex and TimberTech (AZEK). These brands offer the best warranties (25-50 years), superior fade resistance, and realistic wood-grain textures that hold up well in the PNW environment.
Can you reinforce my deck for a hot tub?
Absolutely. Hot tubs are heavy (often 5,000+ lbs full). We must know this during the design phase so we can engineer the framing with extra posts and beams to support the load safely.
Do you offer a warranty on your decks?
Yes. Trust Builds provides a workmanship warranty to cover our installation labor. Additionally, composite materials often come with a 25-year to Lifetime manufacturer warranty against fading and staining.
My backyard is on a steep slope. Can you still build a deck?
Yes, hillside decks are a specialty of ours. We use engineered concrete footings and structural posts to create a safe, stable extension of your home, turning unusable slopes into valuable living space.
