WHAT WE COVER
Composite Deck Builder Services
Across Seattle
Define all six parts of the Seattle composite deck builder scope before work begins. Your written estimate identifies our crew, the included work and your workmanship warranty in writing.
We spell out the project scope in a written estimate before work starts, and your warranty terms are written into your agreement.
01 / COMPOSITE DECK BUILDER
Trex Composite Installation
Compare Trex Transcend, Enhance and Select by color, profile, price and installation requirements. We name the exact collection in your written estimate before work starts. Trex collection and warranty information lists different warranty terms by collection, so we review the terms for the line you choose.
02 / COMPOSITE DECK BUILDER
TimberTech AZEK & Pro Lines
Distinguish TimberTech AZEK/Advanced PVC from wood-plastic composite collections. We check Premier PVC and Pro line options against current product availability. Waterfront, rooftop and budget suitability depend on the actual assembly; we walk you through the options that fit your deck.
03 / COMPOSITE DECK BUILDER
Fiberon & Azek Boards
Review Fiberon Concordia, Paramount PVC and AZEK Vintage by current collection, profile and approved fasteners. We confirm local availability and list the exact products in your written estimate.
04 / COMPOSITE DECK BUILDER
Hidden Fastening Systems
Compare approved CAMO Edge, Trex Hideaway and TimberTech concealed fastening systems for the selected boards. Hidden fastening can create a cleaner face, but perimeter boards, stairs or details may still need approved visible screws. Confirm compatibility rather than mixing systems by appearance.
05 / COMPOSITE DECK BUILDER
Joist Tape & Drainage
Specify compatible joist tape, flashing and drainage details. Trex RainEscape and TimberTech DrySpace are different systems: DrySpace manages water beneath the deck, so it should not be described as the same protection above joists. We match the joist protection to your frame and spell it out in your written estimate.
06 / COMPOSITE DECK BUILDER
Cable Railing Compatibility
Compare stainless cable, aluminum or composite balusters with the chosen post and guard system. Check view lines and the designed connection to the framing. The common 36/42-inch shorthand does not settle the guard requirement for every Seattle building; we confirm the one that applies to yours.
Not sure exactly what you need?

WARNING SIGNS
Is Composite the Right Deck
for Your Home?
Composite and PVC options can change the maintenance and appearance of a Seattle deck. Review these seven priorities alongside cost, framing condition and the chosen product’s limitations.
Deck materials and construction details to consider for your project.
01
Tired of annual cedar staining and sealing
Compare ongoing cedar staining and sealing with the cleaning requirements for the proposed composite. Low maintenance still includes care and inspection.
02
Want 25-30 year fade and stain warranty coverage
Match fade and stain coverage to the exact collection and warranty. The twenty-five-to-thirty-year range is typical, and we review the current terms for the boards you choose.
03
Sensitive to splinters with kids or pets on deck
A different board surface may address concerns about wood splinters. Consider heat, wet traction, edges and damage as well, especially where children or pets use the deck.
04
Building near water and need rot-proof material
Near water, assess the board and the structure separately. A product’s resistance to decay does not make the complete deck or supporting wood rot-proof.
05
Replacing failed pressure-treated lumber deck
Inspect a failed pressure-treated deck before deciding whether only the surface can be replaced. A new board system cannot correct a deficient frame.
06
Want low-maintenance composite over wood lifespan
Compare expected care, material cost and warranty rather than assuming every composite outlasts every wood deck under all conditions.
07
Designing for resale value with premium material
Choose a material that fits the home and budget. Premium branding may appeal to buyers, but it does not guarantee a specific resale return.
Discuss your composite deck builder options.
Describe the property, existing deck and preferred timeline. We’ll confirm a visit time that works for you.

SEATTLE PERMITS
Do You Need a Permit
to Build a Deck in Seattle?
Most new decks in Seattle need a permit, and most need only the quick subject-to-field-inspection permit. Seattle’s building department (SDCI) requires a permit in these three cases, and we tell you at the free estimate which one applies to your deck.
Source: Seattle SDCI deck requirements.
01 / HEIGHT
More than 18 inches above the ground
Measured from the ground to the deck. Lower decks do not need a permit unless one of the next two cases applies.
02 / ROOF DECKS
Built on top of part of the building
Every roof deck needs a permit, and it goes through the full addition or alteration permit.
03 / CRITICAL AREAS
In an environmentally critical area
Such as landslide-prone or flood-prone ground. The city visits the site before any permit application.
04 / MOST DECKS
A quick field-inspection permit
Most Seattle decks need only a subject-to-field-inspection permit. The full addition or alteration permit applies above 8 feet, with beams 14 feet or longer, solid decking or more than 750 square feet.
We check the permit at your estimate.
If your project needs one, it goes into your written scope.

Built for Seattle
Rain, Moss and Salt Air
Rain, evergreen shade, seasonal freeze–thaw conditions and Puget Sound salt exposure all belong in a Seattle composite deck builder assessment. Moss and slow drying can hide moisture problems around board ends and structural connections.
For shaded or north-facing decks in Fremont and Ravenna, inspect moisture retention and ventilation. Waterfront properties around Magnolia and Alki may need additional attention to corrosion. Sloped or elevated sites in Queen Anne and Capitol Hill call for a close review of supports and access. We confirm the actual conditions at each address.
- Compatible stainless or coated fasteners. Select for the lumber treatment, connector and exposure.
- Appropriately treated framing. Use ground-contact-rated material where the assembly and exposure require it.
- Joist and ledger moisture protection. Detail flashing, drainage and protection tape as part of the repair.
- Finishes suited to the site. Confirm any marine-grade or waterfront coating against the product’s approved uses.
Read the background on deck construction and repair and the Seattle SDCI deck requirements.
Plan for repeated Seattle rain, shade and drying conditions at the actual property. Specify corrosion-compatible stainless or coated fasteners as part of the complete lumber, connector and exposure design.

Composite decks in Seattle start at $28 per square foot. Composite railing starts at $20 per linear foot and stairs at $31 per step, with up to 25% off qualifying projects. Your exact price comes from the free on-site estimate.
We can compare complete installed scopes for a 300 sq ft / about 28 sq m deck using Trex Transcend, TimberTech AZEK or mid-grade Fiberon. Your estimate should identify the structure, boards, fasteners, railings, access and permits so you can see the actual material and installation differences.
Material choice is only one part of the project-specific quote.
Up front, yes. Composite starts around $28 per square foot and wood around $18. Composite skips the staining every few years, so the gap shrinks over time.
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.
We can compare Trex Transcend, TimberTech AZEK and Fiberon Paramount PVC against your Seattle property’s exposure, framing, appearance and budget. Review samples and specifications for the exact collection alongside the installation requirements.
Check actual samples and current warranties. AZEK and Paramount are PVC options in this comparison; they should not be treated as identical to wood-plastic composite boards.
We can discuss service life through the complete installation: boards, supporting structure, drainage, exposure and care. Compare composite and PVC using the selected products rather than one lifespan for either material.
Current Trex collection and warranty information identifies fifty-year limited residential coverage for Transcend, thirty-five for Select and twenty-five for Enhance, subject to its terms. We can review the TimberTech and Fiberon documents for the exact collection alongside those Trex options.
Yes. We can discuss the selected product’s cleaning guidance and a care plan for debris, drainage and the supporting structure. Seattle shade and exposure affect how often the deck needs attention.
Capped composite generally does not use wood-style staining, sealing or sanding. We can compare its cleaning needs with cedar preparation and recoating, including the actual work and costs in your maintenance plan.
Only after the existing structure, connections and foundation are assessed and the board manufacturer’s installation requirements can be met. Check joist spacing, blocking, ventilation, flatness and intended board direction.
We can discuss the selected board’s support spacing for your layout. Angled boards, stairs and particular profiles may require closer supports; include any framing correction or replacement in the quote and check pressure-treated wood compatibility.
Use the same deck size and structural scope to compare Trex Transcend, TimberTech AZEK and Fiberon Paramount. Review real samples for color and feel, then compare current warranty, maintenance and product availability.
Bring us your priorities for resale appeal, color, waterfront or rooftop use and budget. We can compare samples and installation requirements for your project.
Financing options are available for your deck project; ask about them during your free phone consultation. If you plan to finance your project, get your lender’s written terms before you commit.
Ask for the cash project price and the complete financing terms separately.
Ask for written coverage of framing, ledger attachment, footing connections, railings and stairs, together with exclusions, claim steps and any transfer rights on sale. Talk with us about the workmanship coverage for your project. Only the contractor’s written warranty establishes the duration and coverage.
We can review Trex, TimberTech and IPE material coverage separately from workmanship coverage. Match the exact product, collection, purchase date and installation requirements to the manufacturer’s current warranty, then confirm the contractor’s written terms for the agreed work.
