Start with the calculator

Use the calculator first so the DIY and contractor comparison starts from the same project size and assumptions.

When DIY can make sense

  • A low, simple deck whose framing, footings, ledger, and railings have already been confirmed sound
  • A rectangular surface with limited board replacement and manageable access for materials
  • You can follow the selected board system's fastening, spacing, and flashing requirements

When a contractor can make sense

  • Soft, moving, cracked, or water-damaged framing, posts, beams, footings, railings, or stairs
  • An elevated or attached deck, complex geometry, hidden fasteners, or major old-board removal
  • Any uncertainty about structure, code, permits, railing safety, or the ledger connection

How to decide

  • Resurfacing can save money only when the supporting structure is truly sound; it is not a substitute for structural repair.
  • DIY is most realistic on a low, simple deck after a thorough inspection, while attached or elevated decks deserve a professional assessment first.
  • Ask bids to separate decking, hidden fasteners, removal, framing repair allowances, railing or stair installation, and disposal so scope is comparable; the calculator's railing and stair selections are materials-only allowances.

Worked example

16 ft by 12 ft deck to resurface with composite boards.

Replacement decking
201.7 sq ft
192.0 sq ft deck surface plus 5% waste
DIY materials
$1,808–$6,036
Decking, fasteners, prep, disposal, and selected railing or stair refreshes
Contractor planning total
$3,709–$11,162
Surface labor plus materials; railing/stair installation labor is excluded

Starter shopping list

  • composite decking 201.7 sq ft
  • Deck screws or hidden fasteners 1,614 planning count
  • Flashing, joist tape, blocking and repair materials standard prep allowance
  • Railing refresh materials Not included

This example is generated from the same calculator logic used on the Deck resurfacing calculator page.

Cost factors to compare

  • Deck surface area, waste, decking material, fastener system, and board availability
  • Old-board removal, disposal, joist tape, flashing, blocking, and surface preparation
  • The amount of framing repair discovered after boards are removed
  • Railing and stair material allowances, separately quoted installation labor, access, and permits

Contractor quote checklist

  • Inspection of joists, beams, posts, footings, ledger, flashing, and railings described
  • Decking product, color, board orientation, fastener system, and waste allowance listed
  • Old-board removal, disposal, joist tape, blocking, and surface prep clearly scoped
  • Framing-repair unit pricing or a stated allowance included for concealed damage
  • Railing and stair materials separated from their installation labor; permit, code, cleanup, and warranty responsibilities made explicit

Common mistakes

  • Covering structural problems with new boards instead of repairing the deck safely
  • Buying decking without the compatible fastener, spacing, flashing, and joist-protection system
  • Comparing resurfacing bids that differ on removal, disposal, framing repairs, or separately quoted railing and stair labor
