Restoration: keep a suitable surface
Cleaning or refinishing may suit an otherwise serviceable natural-wood deck. Establish the condition first, then choose a compatible preparation and finish. Color fading and structural deterioration are different issues.
Resurfacing: keep a suitable frame
New deck boards can change appearance and upkeep when the supporting structure is appropriate. Ask the contractor to assess retained components and identify product-specific support or fastening changes.
Replacement: rebuild the system
A replacement may be appropriate for deteriorated supports, unsuitable connections, significant layout changes or a broader redesign. Compare a clear full scope with any partial approach, and discuss how hidden damage will be handled.
Questions worth asking
Can I make the decision from the age of the deck?
Age provides context but does not establish the condition or suitability of the actual structure.
Can I reuse old railings?
Only if they remain appropriate for the design, condition and applicable requirements. Ask for them to be assessed.
