Composite decking in Appleton

Boards that don't need sealing every other spring, on a new deck or on a frame that still checks out.

Composite decking is the most common upgrade for Appleton homeowners who are done scrubbing and sealing wood. Across the Fox Cities, it goes on new decks and on older decks whose frames are still solid, and it gives you a surface that holds up to snow and rain with little more than washing.

Composite, PVC and wood compared

BoardStrengthsWatch for
Capped compositeWide color range, no sealing, slip-resistant texturesHeavier; needs proper joist spacing
PVCLightest, most moisture-resistantHigher price; more expansion with temperature
Treated pineLowest cost, easy to replace a boardNeeds sealing; splits and cups when wet-dry cycles repeat
CedarNatural look, lighter weightSofter; needs finish to keep color

Why it makes sense here

Appleton gets about 33 inches of precipitation and nearly 50 inches of snow a year. Wood boards spend a lot of the year damp, and snowmelt sitting on them is how sealer fails and rot starts. Capped composite and PVC don't absorb water the way wood does, so they don't need a sealing schedule. The frame underneath is still treated wood, so ledger flashing and joist protection matter just as much.

Resurfacing an existing deck

If the frame is sound, new composite boards can go on top. Before that, a builder should check:

  • Joist spacing against the board manufacturer's limits, since many composites need closer spacing than old wood decks used
  • Rot on joist tops and around the ledger, where water sits longest
  • Footing depth, especially on decks built on surface blocks
  • Railing posts, which are often easiest to replace at the same time

Signs it's time to switch

  • Sealer peels or wears through every year
  • Boards are splitting, cupping or growing mildew
  • You're replacing several boards every season
  • The deck is slippery after rain in shaded spots

Winter care

Use a plastic shovel and push along the boards, not across them. Many composite manufacturers publish which ice melts are safe for their products; rock salt and some chemicals can leave residue or stain. Shaded north-facing decks can grow mildew on any material, so an occasional wash helps.

What sets the price?

  • Board line, color and texture
  • Hidden fasteners and picture-frame edges
  • Added joists or blocking on an older frame
  • Matching fascia, stair treads and railings
  • Tear-off and disposal of old boards

Common questions

Can composite boards go on my old deck frame?

Often, if the joists, ledger and footings are sound and the joist spacing meets the board maker's requirements. Extra joists are sometimes added.

Is composite slippery in winter?

Any deck can be slippery with ice. Many composites have textured surfaces; use a plastic shovel and an ice melt the manufacturer lists as safe.

Does composite stop rot?

The boards don't rot like wood, but the frame under them is still treated lumber. Flashing and joist protection still matter.
