New Day Construction is a family-owned general contractor serving homeowners throughout the Greater Seattle area. We build residential decks and coordinate outdoor improvements, including projects connected to larger home renovations and additions. Our team plans the structure, materials, drainage, and construction requirements around your property and the way you want to use the space.
We help homeowners define the scope for a new deck or replacement structure before construction begins. Call (425) 584-2936 or request a project consultation.
Practical step-by-step overview
Before building a deck, it's important to understand how the proposed structure will fit the property and connect with the existing home. We review the intended use, available space, site conditions, access, and potential structural requirements before developing the construction scope. Early planning also helps identify whether the design will require engineering, additional site work, or permits.
Key components and moisture management
The structural components depend on whether the deck is attached to the house or freestanding. An attached deck may use a ledger board, while a freestanding design relies on its own supporting structure. In either case, posts, beams, joists, connectors, and footings must work together according to the approved design. Pressure-treated wood or other approved decay-resistant material may be specified where exposure requires it. At an attached deck, the plans should address flashing and water movement away from the house without relying on a generic connection detail. Connector compatibility, drainage, ventilation below the deck, and product-specific installation requirements should be reviewed before materials are ordered.
Final Inspections and Project Closeout
Deck construction requires inspections at the stages specified by the local permitting authority, including inspections before certain structural work is covered. Once the required work and final approvals are complete, we review the finished deck with the homeowner, document any remaining corrections, and discuss appropriate maintenance for the selected materials. Product-specific care instructions help homeowners understand how to maintain decking, railings, and other exposed components.
What Is Included in Deck Construction?
A complete deck is more than deck boards. Depending on the design, the construction can include concrete footings, posts, beams, joists, a ledger or freestanding frame, blocking, approved connectors, decking, fascia, guards, handrails, stairs, and landings.
The plans also need to account for height, grade, property setbacks, access, door thresholds, drainage, flashing, utilities, and the expected loads. Lighting or other electrical features require coordination with the appropriate trade and permit path.
Attached and Freestanding Decks
An attached deck uses a designed connection between the deck frame and the house. That connection requires careful structural and water-management detailing. The ledger, fasteners, flashing, and existing wall condition must work together so the attachment does not create a path for moisture.
A freestanding deck supports itself independently from the house. It can be useful when an appropriate ledger connection is not available, but it still requires correctly located footings, posts, beams, bracing, and transitions at the door.
The right approach depends on the property and design. A contractor should not choose between attached and freestanding construction without reviewing the building, grade, desired height, and local requirements.
Deck Framing and Load Path
The deck frame transfers weight from the decking and people above through joists, beams, posts, and footings into the ground. Each member must be selected and spaced for the design, material, span, and applicable building codes. Each structural component has a specific role in supporting the deck and transferring loads safely to the ground:
- Joists support the deck boards and span between the ledger or beams.
- Beams collect loads from the joists and transfer them to posts.
- Posts and footings carry the structure to suitable bearing below.
- Joist hangers and other connectors must match the framing and approved fastener requirements.
- Guards, handrails, stairs, and landings require their own code-compliant dimensions and connections.
A hot tub, roof, outdoor kitchen, heavy surface, stacked deck, unusual height, steep site, or nonstandard attachment can require additional engineering. These features should be identified before deck plans are completed.
Wood and Composite Decking Materials
The walking surface can be built from wood or composite deck boards, but the choice should be made in the context of the whole project.
Wood decking offers a natural appearance and can be finished in different tones. Maintenance depends on the species, exposure, finish system, and product instructions. Composite decking can reduce some routine finishing requirements, but products differ in color, texture, heat response, expansion guidance, span limits, and fastening systems.
Pressure-treated lumber may be used in framing where specified, while decking and visible trim can follow a different material plan. Fasteners and connectors need to be compatible with the lumber treatment and exposure conditions.
Repair, Resurface, or Build a New Deck?
New boards cannot correct a failing structure. Before reusing an existing deck frame, review the footings, posts, beams, joists, ledger, connections, guards, stairs, corrosion, decay, movement, and water entry at the house.
Resurfacing may be possible when the structure is suitable and the intended layout and loads are not changing. Replacement can be more appropriate when damage is widespread, the design needs to change, or the existing deck does not provide a clear path to current requirements.
Deck Design Decisions
A well-designed deck should fit both your property and the way you plan to use the outdoor space. Before finalizing the design, we review the following considerations:
- deck size, height, shape, and relationship to the home;
- attached or freestanding framing;
- stair and landing locations;
- guard design, privacy, and sightlines;
- door thresholds and indoor-outdoor circulation;
- decking direction, fascia, borders, and transitions;
- access beneath the frame and water management;
- lighting and other electrical features;
- loads from heavy or covered features;
- future maintenance access.
What Affects Deck Construction Cost?
Construction cost depends on the design rather than one universal square-foot number. Size, height, slope, access, demolition, hauling, footings, structural framing, stairs, railing, decking material, trim, permits, engineering, and electrical work can all change the scope.
Ask each bidder to separate structural work from finish selections and state what will be removed or reused. The proposal should identify permits, inspections, allowances, exclusions, cleanup, and the change-order process. A low number based on unverified framing is not comparable to a scope that includes a new structure.
Our Deck Building Process
- Consultation: discuss intended use, existing conditions, size, materials, and budget framework.
- Site review: examine grade, access, setbacks, utilities, the house connection, and existing structure.
- Design and scope: define layout, framing approach, stairs, railing, materials, and design-professional needs.
- Proposal and permits: document inclusions, selections, responsibilities, and construction sequence.
- Construction and inspections: coordinate demolition, foundations, framing, decking, guards, stairs, and required inspections.
- Final walkthrough: review the agreed scope and document remaining corrections.
Permits and Local Building Codes
Deck permit requirements vary across the Greater Seattle area. In Seattle, a construction permit is generally required for decks more than 18 inches above the ground, roof decks, and decks in environmentally critical areas. Bellevue generally requires permits for decks more than 30 inches above the ground, with additional requirements for certain structural repairs, stairs, and railings. These differences make it important to confirm the applicable rules for your specific property before construction begins.
The local permitting authority should be confirmed for the exact address. Deck plans may need to show property setbacks, footings, structural framing, connections, guards, stairs, and landings. Required inspections must be completed at the appropriate construction stages, followed by final approval. Review the official Seattle SDCI deck guidance or Bellevue permit requirements, depending on your property's jurisdiction.
How to Choose a Deck Contractor
Ask who prepares the plans, manages permits, schedules inspections, and communicates during construction. Review the proposed load path, attachment, flashing, materials, fasteners, exclusions, and change process.

FAQ
How much does it cost to build a deck?
Cost depends on size, height, access, slope, demolition, footings, framing, stairs, railing, decking, permits, engineering, and other design details. A site-specific scope is more reliable than a generic square-foot figure.
Can I reuse an existing deck frame?
Possibly, if its structure, connections, footings, guards, and stairs are suitable and the new design does not exceed its capacity. The frame should be reviewed before new boards are specified.
Does every deck require a permit?
No. Exemptions vary by city and design. Confirm the rules for the exact address, height, size, attachment, and intended use before building.
How long does deck construction take?
Duration depends on design, permit review, engineering, material availability, access, demolition, inspections, and weather. A meaningful schedule follows a defined scope.
