Construction Details of Stumps Quality Decks & Porches

  Joists and beams   Dry lumber for straight decks  
  Stump's Quality Decks & Porches uses #1 grade joists and beams, which are stronger than the industry standard (#2 grade). #1 grade lumber has fewer knots, meaning beams and joists will have a stronger resistance to sagging and warping over time.   Installing wet lumber increases the chances wo warping over time, leading to an uneven deck surface. At Stump's Quality Decks & Porches, we air dry our lumber in our lumberyard, greatly minimizing moisture content and maximizing strength.

(For example, we may use 2x8 joists instead of our standard 2x10 joists on smaller decks.)
