Separate the project types
A new deck needs a complete foundation, frame and finished system. Full replacement adds removal and disposal and may change the existing layout. Redecking retains suitable components and replaces the walking surface. Repair addresses specified damage. Those scopes cannot be compared through one price-per-square-foot figure.
Ask what the proposal includes and what remains uncertain until removal or further assessment. A low headline can omit railings, stairs, footings, structural repairs or cleanup.
Size and elevation
Footprint is important, but height and the shape of the property can change supports, access and stair design. Multiple levels add transitions and framing details. A simple shape with usable circulation can be a better use of the budget than a complicated layout.
Measure the approximate height at the house and at the outer edge. On a sloped yard, those measurements can differ. Explain gates, narrow access or other constraints that affect material delivery and debris removal.
Materials and finishing
Compare the exact decking collection, rail system and stair finish. Wood, composite and PVC have different product and support requirements. The complete system includes fascia, fastening and any specified finishing.
A roof, screens, pergola or under-deck drainage system adds its own structure and installation work. Identify those additions separately so the board-built deck portion remains understandable.
Design, permits and unknown conditions
Applicable site-plan, permit and design work belongs in the proposal. Existing conditions may reveal additional damage when old boards are removed. Agree how findings and changes will be documented before work begins.
A deck intended to support a spa or another unusual load needs that use disclosed. Guilford County guidance identifies decks supporting hot tubs and spas as needing a registered design professional. Do not rely on a standard deck allowance for an undisclosed load.
Compare written proposals
Use the same footprint, product choices and project scope when comparing options. Check removal, supports, house connection, rails, stairs, required inspections and cleanup. Discuss assumptions and exclusions in writing.
Describe the planned deck in the inquiry, including its size and height, condition, preferred materials and added shelter or drainage. An on-site assessment is still needed to establish a property-specific construction proposal.
