ABOUT DECK BUILDERS SEATTLE
Seattle Deck Builders.
Experience, Materials & Craftsmanship.
Seattle deck construction starts with the structure: foundations, ledger connections, framing and drainage. Repair, restoration and new installation each need a scope that fits the property.
We help Seattle homeowners plan deck repair, replacement and custom deck design around their property. Tell us what you want to change, and ask about relevant completed projects, the construction team and the experience needed for your deck.
Material planning covers Western Red Cedar, IPE hardwood, Trex, TimberTech, Fiberon composite and PVC. Compare upfront cost, cleaning, re-staining and product warranty terms. Crew assignments, SDCI or King County permit responsibilities and the written workmanship warranty belong in the project scope.
Seattle homes are different block by block. A Capitol Hill townhouse, a sloped Magnolia yard and a Madrona property can call for different access, foundations and deck layouts. Review the actual site before settling on a design.
Compare Western Red Cedar, IPE hardwood, Trex Transcend and TimberTech AZEK alongside Fiberon composite and PVC. Include cleaning, refinishing, product warranties and installation requirements in that comparison.
Useful resources: Seattle · NADRA deck resources · SDCI · King County. Use these resources to explore local deck planning, safety and permitting.
Your workmanship warranty terms are written into your agreement, separate from the decking manufacturer’s product warranty. Cedar finishing needs depend on the selected coating and exposure; composite and PVC also need care. Real Cedar’s maintenance guidance recommends annual cleaning and clear drainage and warns that power washing can damage cedar.
12 SEATTLE DECK BUILDER FAQS
Questions Seattle Homeowners
Ask Deck Builders
Cost, permits, materials and timing. Start with the questions that help define the project.
Still have questions?
Tell us what you know so far. The next useful step starts with your property.
Deck repairs in Seattle start at $199. New wood or cedar decks start at $18 per square foot, composite decks at $28 per square foot and deck staining at $1 per square foot, with up to 25% off qualifying projects. Your exact price comes from the free on-site estimate.
The useful starting point is a defined scope. Size, deck height, site access, structure, board selection, railings, removal and permit work all affect price. Ask for a written estimate that identifies inclusions and exclusions, rather than applying one square-foot price to every property. Compare like-for-like proposals: the same deck footprint, board series, railing system and foundation assumptions. A ground-level wood deck, elevated composite deck and multi-level hardwood build will not share the same scope. Western Red Cedar, Trex Transcend, TimberTech AZEK and IPE hardwood deserve separate material allowances. Ask whether engineered design, demolition, disposal, flashing, connectors, hidden fasteners and permit fees are included.
Compare a 300 sq ft deck by material and scope. Request separate installed allowances for cedar, Trex or TimberTech composite, and IPE hardwood. Five major cost drivers are deck size, material, elevation and structure, hardware, and permit work. Specify Simpson Strong-Tie connectors where designed, hidden fasteners, railings and stairs in the same quote.
For a quick benchmark, composite decks start at $28 per sq ft and wood decks at $18. We can compare Trex with cedar, TimberTech and IPE proposals that also include labor, demolition, access and permits. Call us for a written estimate for your Seattle deck.
Both. We repair, restore, refinish and stain existing decks, and we build new ones in cedar, pressure-treated wood, composite, PVC and Ipe.
Yes. The on-site estimate is free and comes with no obligation. You get a written price and decide on your own time.
Tell us the size of the deck and what you see, and send photos if you have them. That is enough to talk through the likely scope on the phone. The exact number comes from the free visit, because rot, footings and framing hide under the boards.
If your project needs a Seattle permit, we tell you at the estimate and include it in your written scope. Most decks need only a subject-to-field-inspection permit from Seattle SDCI.
Permit requirements depend on the jurisdiction and project. Seattle SDCI says a construction permit is needed for a deck more than 18 inches above the ground or a roof deck. Site conditions can introduce additional requirements. Check Seattle’s current deck guidance for the actual property before proceeding. The height and location are only the starting point. Roof decks, changes to the structure, property setbacks and environmentally critical areas can affect the review. Confirm which documents, drawings and inspections apply before assuming that replacing an existing footprint is automatically exempt. Outside Seattle, use the requirements of the actual permitting jurisdiction. Keep the approved scope and any contractor responsibilities clear in writing.
The permit package may need structural drawings, ledger attachment details and footing specifications. Seattle SDCI also identifies environmentally critical areas as a permit consideration. For Bellevue or Kirkland, confirm the relevant city requirements; unincorporated King County has a different authority. Permit review time depends on the application and review required. Obtain a project-specific review allowance before fixing the construction date.
The right choice is a contractor whose registration, insurance and written scope are clear from the first call. We are a registered Washington contractor, we carry $1 million in general liability insurance with a certificate available for your project, and we are a BBB Accredited Business.
When comparing Seattle deck builders, start with our free phone consultation, with no obligation. We explain how structural work, permits, changes and warranty responsibilities will be handled, you get a written deck construction quote before work starts, and your workmanship warranty terms are written into your agreement.
There is no single material for every Seattle property. Compare cedar, hardwood, composite and PVC by their appearance, product-specific installation requirements, exposure, care and budget. Drainage and the condition of the supporting structure matter alongside the boards you choose. Western Red Cedar brings natural wood character and requires an appropriate care plan. Cedar versus composite upkeep is an important comparison. Trex Transcend and TimberTech AZEK should be reviewed by the exact collection, not just the brand name. Consider IPE hardwood and PVC decking as well. Rooftop and waterfront material choices introduce additional exposure and assembly questions. Read our Seattle wet-climate material guide alongside the manufacturer’s instructions.
Match the deck material to upkeep and exposure. Cedar brings natural wood grain; compare its upfront installed price with the cleaning and re-staining plan for your chosen finish. Composite avoids routine wood staining, but still needs cleaning. Warranty length varies by collection: Trex lists 25–50-year residential product warranties, subject to the applicable terms. Product coverage is separate from a contractor’s structural or labor warranty.
Check samples for heat underfoot on a sunny, south-facing deck, even when a board has heat-mitigation features. For IPE, discuss expected service life, rot and insect resistance, sourcing and the finish needed to retain its color. For PVC on a waterfront or rooftop deck, review the full assembly, fastening and expansion requirements. Seattle rain makes board gaps, drainage, airflow and debris removal part of every material decision.
We explain who will carry out the work, what the quote includes, who handles permits, how changes are approved and what written warranties apply. We assess the existing ledger, rails, supports and stair connections, and we go over the manufacturer’s product warranty for the materials you choose alongside the workmanship terms written into your agreement.
What you get with us as your Seattle deck contractor:
- We are a registered Washington contractor.
- We carry $1 million in general liability insurance, with a certificate available for your project.
- We are a BBB Accredited Business.
- You get a written estimate before work starts, covering SDCI permits, required engineering, ledger flashing, joist tape and disposal where your project needs them.
- Your workmanship warranty terms are written into your agreement.
- Every project starts with a free phone consultation, no obligation, and financing options are available.
An extension may be possible, but the existing deck needs assessment. Supports, framing, connections, loads and the new layout should be reviewed together. Keeping the current structure is a decision to evaluate, not an assumption to build around. An extension can introduce new loads and connections even when the surface appears sound. Discuss the new supports, stairs, railings and access as well as whether the original frame is suitable. On compact Capitol Hill properties or sloped Queen Anne sites, the layout and permit context may need particular attention. The assessment should explain what can be retained and what needs to change.
Before pricing a deck extension, we inspect the existing ledger attachment, footing depth and condition, and joist spans for the proposed loads. We document damaged framing and the connections between old and new work. We specify the designed connectors, including any Simpson Strong-Tie hardware, flashing and joist tape. These details and the applicable permit review belong in the extension quote, rather than assuming new boards make an older frame suitable.
A small repair and a new elevated deck follow different schedules. Design, permit review, material availability, site conditions and the construction scope all contribute. Ask for a project schedule that distinguishes planning and approvals from the work on site. Separate the lead time from the construction duration. Surveying, design decisions, engineering when needed, permit review and material ordering may occur before site work begins. Demolition can reveal conditions that affect a repair or rebuild. Agree how weather, inspection scheduling, concealed damage and owner-approved changes will be communicated. Ask for updates at clear milestones rather than relying on a generic number of days.
Ask for separate schedules for board or railing repairs, resurfacing over retained framing, a new 300 sq ft deck, a multi-level hillside build and a rooftop installation. A Capitol Hill rooftop or Queen Anne hillside project can involve different access and design questions from a small repair. Confirm permit lead time, procurement and on-site work separately; talk with us about the visit, planning and construction dates that fit your actual scope.
Wildland–urban interface requirements depend on the property, jurisdiction and rules in force when the project is reviewed. Do not assume a requirement applies to every Seattle address. Confirm the applicable code and accepted decking/assembly details with the local permitting authority before specifying materials. Fire performance is product- and assembly-specific. A generic material label or a rating quoted for a different product does not settle compliance. Compare the documented requirements for the selected Trex, TimberTech AZEK or IPE option and read the hardwood versus composite comparison. Ask the authority having jurisdiction which classifications, approvals and installation details apply to the address and project date.
For a project subject to WUI provisions, ask about fire-resistant decking options, board gaps and potential ember entry, and metal flashing at the wall-to-deck connection. Confirm the complete tested or accepted assembly and the exact Trex, TimberTech or IPE product documentation. Neither a universal board-gap rule nor a general material name establishes approval; resolve the details with SDCI or the actual permitting authority.
