What Drives Dec-Tec Pricing

  1. Substrate condition

    Sound plywood adds minimal cost; rotted joists or failed underlayment can add $500-$3,000.

  2. Product line

    CoolStep runs about 10-15% more than Classic and is usually worth it for sun-exposed surfaces.

  3. Complexity factors

    Railings, stairs, multi-level decks, pipe penetrations, and hot-tub cutouts all add labor.

  4. Deck size

    Per-square-foot cost drops as size increases because setup time is spread across more surface area.

  5. Access

    Ground-level decks cost less than second-story decks that require more staging and material handling.

Dec-Tec vs Alternative Deck Surfaces - Long-Term Ownership Cost

  • Wood deck and stain

    $8/sq ft plus $3/sq ft refinishing every 2-3 years, or about $28/sq ft over 20 years.

  • Composite decking

    $15-$25/sq ft with minimal maintenance, but it is not waterproof and usually needs separate underlayment.

  • Concrete and epoxy coating

    About $12/sq ft plus $4/sq ft resealing every 5 years, or roughly $24/sq ft over 20 years.

  • Dec-Tec

    $15-$25/sq ft installed, near-zero maintenance, and about $17-$27/sq ft over 20 years as the finished waterproof layer.

  • Elevated deck note

    Over living space, Dec-Tec can replace a separate waterproofing layer that might otherwise add $5-$10/sq ft.
