Why Hire a Design-Build Contractor for Your Deck or Patio

Most deck contractors provide a catalog, ask you to select a material, and begin construction. You only see the final result at completion. Renovision’s design-build process lets you preview the finished project before work begins.

Our AI-powered 3D design creates a photorealistic rendering of your new deck or patio, including railing style, decking material, overhead structure, lighting, and integration with your home and yard. You approve the design before construction begins. Design-stage changes are free, while changes during framing can be costly.

In addition to design, our in-house team manages all aspects of your project, including carpentry, concrete, electrical work for lighting and outlets, and finishing. There are no subcontractor handoffs; you have one crew, one schedule, and a single point of accountability.

Deck & Patio Services We Build

Wood Decks

We build decks from cedar, pressure-treated pine, and thermally modified wood, designed for the Pacific Northwest climate. Cedar remains the most popular choice in the Eastside market due to its for its natural beauty, rot resistance, and its ability to complement the wooded-lot character found in Bellevue, Kirkland, and Sammamish.

Built-in features: Benches, planters, and storage
Shade options: Integrated pergola or shade structure
Railing options: Cedar, cable, glass, or composite

Composite Decks

Low-maintenance composite decking (Trex, TimberTech, Fiberon) is ideal for homeowners seeking a durable deck that withstands the PNW wet season without the yearly upkeep required for wood. Composite materials do not rot, splinter, or need annual sealing.

Capped composite: Premium option that resists staining and fading
Uncapped composite: Cost-effective and requires significantly less maintenance than wood
Color selection: Wide variety from natural wood tones to modern dark grays
Fastener systems: Hidden fasteners that create a clean, seamless deck surface

Covered Patios & Pergolas

Covered outdoor spaces can extend Seattle’s usable season from about four months to ten. A well-constructed pergola or solid-roof patio offers the most significant outdoor improvement for Pacific Northwest homes.

Freestanding pergolas: Cedar or steel frames with open lattice or louvered roofs
Attached covered patios: Fully permitted solid roofs in shed, gable, or hip styles
Adjustable louvered roofs: Aluminum systems that open for sun and close for rain
Utility integration: Rough-ins for integrated lighting, ceiling fans, and outdoor heaters

Paver & Concrete Patios

Ground-level patios extend your living space without the complexity of a raised deck. Pavers provide effective drainage, withstand frost cycles, and can be repaired without replacing the entire surface.

Concrete pavers: Interlocking, natural stone-look, and permeable options
Poured concrete: Broom texture, exposed aggregate, or stamped patterns
Natural stone: Flagstone, bluestone, and slate finishes
Hardscape integration: Steps, retaining walls, and landscape edging

Outdoor Kitchens & Living Spaces

We provide complete outdoor kitchen installations, including integrated grills, countertops, refrigerators, sinks, and covered dining areas. Our in-house teams manage all required electrical, gas, and plumbing work.

Built-in grill stations: Stainless steel components with stone or tile surrounds
Outdoor countertops: High-durability porcelain, natural stone, or concrete surfaces
Integrated appliances: Weatherproof outdoor refrigerators and functional sinks
Fire features: Built-in fire pits or fire tables that serve as focal points

What's included

Do Decks Require Permits in the Seattle Area?

Yes, in most cases. Thresholds and requirements vary by city, but the general rule in the Seattle metro area is:

Decks over 30 inches above grade require a building permit in virtually every jurisdiction.
Decks attached to the home require a permit regardless of height. The ledger connection is considered a structural element.
Covered structures (pergolas with roofing, solid-roof patios) require permits in all Seattle-area cities.
Electrical work (outdoor lighting, outlets) requires a separate electrical permit.

Unpermitted decks must be disclosed during a home sale and may require permit legalization by the lender, which often costs more than obtaining the original permit. As your licensed general contractor, we secure all necessary permits. Permit compliance is included in every project from the initial consultation.

Permit processing times in the Seattle metro area range from 4 to 10 weeks, depending on the city and project complexity. We factor this into every project schedule to ensure a realistic build timeline from the outset.

Our 4-Phase Deck & Patio Build Process

Free Outdoor Design Consultation

We visit your property in person. If you prefer, you can also meet us at our Bellevue office, but most outdoor projects begin with an on-site visit. We look at your yard, the slope, sun exposure, and how the space connects to your home. Within 48 hours, you’ll receive a preliminary AI 3D rendering and a project overview.

Design & Proposal

We refine the design with your input, including material selection, railing style, overhead structure, and layout. Once you approve the design, we provide a detailed, itemized proposal with a fixed price and a guaranteed start date. There is no hourly billing and no open-ended estimates.

Permitting & Construction

We take care of permits with the appropriate city department, whether that’s the City of Seattle, Bellevue, Kirkland, or wherever your home is located. Our in-house team manages framing, decking, electrical work, and any concrete or masonry tasks.

Final Walkthrough

We review the finished deck or patio with you before completing the project. For a standard deck, the typical timeline is 8 to 14 weeks from the signed contract to the final inspection. Covered structures or outdoor kitchens usually take 12 to 20 weeks. The schedule may vary depending on permit requirements.

Deck & Patio FAQ

How long does it take to build a deck in the Seattle area?

A standard single-level wood or composite deck in the Seattle area typically takes 8 to 14 weeks from consultation to completion. This includes 4 to 8 weeks for design and permitting, depending on the city’s review timeline, and 2 to 4 weeks for construction of a 200–400 sq ft deck once permits are approved. Multi-level decks with covered structures or outdoor kitchens require 12 to 20 weeks. Permitting is the largest variable. Seattle DCI reviews can take 6 to 10 weeks, while Bellevue and most Eastside cities usually process permits in 4 to 8 weeks. We include permit timelines in the project schedule from the initial consultation and begin construction only after permits are secured. Some cities offer expedited permit review for an additional fee. We can discuss this option during the design phase if your timeline is critical.

What decking material is best for Seattle’s climate?

The Pacific Northwest’s wet season, from October to May, is the main consideration when selecting decking materials. Capped composite, such as Trex Transcend or TimberTech Azek, is the most durable choice for Seattle-area decks. It resists moisture, rot, and splintering, and maintains its color for over 25 years without refinishing. Although composite costs 40–60% more than pressure-treated wood initially, it eliminates the need for annual sealing, staining, and board replacement. Cedar is the leading natural wood option, offering rot resistance, stability in wet conditions, and an appearance that complements wooded lots common on the Eastside. Pressure-treated pine is the most economical but requires regular maintenance. For homeowners planning to stay at least five years, composite typically recoups its higher upfront cost through maintenance savings by year six to eight. We review these trade-offs at every consultation with detailed cost-of-ownership comparisons.

Does my deck need a permit in Seattle or Bellevue?

In almost all cases, a permit is required. In Seattle, any deck attached to the home or over 18 inches above grade requires a permit. In Bellevue, Kirkland, Redmond, and most Eastside cities, the threshold is typically 30 inches above grade, but decks attached to the home require a permit regardless of height because the ledger connection is a structural element subject to code inspection. Covered structures, including pergolas with roofing or solid-roof patios, require permits in all jurisdictions we serve. We have seen homeowners skip permits on decks that were later flagged during home sales. Lenders often require permit legalization as a closing condition, which usually costs more than the original permit. We obtain all necessary permits and do not build without them. If a contractor tells you a deck does not need a permit, confirm this with your city’s building department before proceeding.

Can you build a deck or patio on a sloped lot?

Yes, we can build on sloped lots, which often result in distinctive deck designs in the Seattle area. Lots that slope away from the house are ideal for multi-level decks or daylight lower patios. High decks require additional structural elements, such as posts, beams, lateral bracing, and concrete piers below the frost line. These features increase costs compared to ground-level decks, but the visual impact is often greater. We incorporate the slope into our AI 3D design so you can see how the deck will fit the grade, including sightlines from main living areas and views from the yard. For lots with more than four feet of drop under the deck, we include structural engineering in the permit package, as required by all Seattle-area building departments.

What is the ROI on a deck or patio in the Seattle market?

According to Remodeling Magazine’s Cost vs. Value report for Seattle, wood decks recoup about 65–75% of their cost at resale. Composite decks return slightly less initially but offer greater value over ten years due to lower maintenance costs. In the Eastside market, where homes often sell for $1.2M to $2.5M, a well-built covered deck or outdoor kitchen is a key selling point, as buyers in this range expect finished outdoor living spaces. Beyond resale, the lifestyle benefit is immediate. A covered patio can extend your outdoor season from four to ten months, enhancing year-round use. Most clients prioritize lifestyle improvements and view resale value as confirmation of a wise investment.
