Proper deck gapping preserves the clean, beautiful look of your outdoor space by allowing essential drainage, airflow, and natural expansion. Through our Proven Process, Green Shield builds low-maintenance decks engineered to last a lifetime.
What is Deck Gapping?
Deck gapping is the deliberate, calculated spacing left between deck boards to allow proper airflow, rapid water drainage, and structural breathing room.
Video Description
Deck gapping is the deliberate, calculated spacing left between deck boards to allow proper airflow, rapid water drainage, and structural breathing room. Because outdoor materials expand and contract with fluctuating temperatures and moisture, exact spacing is essential. Without it, trapped debris and standing water accelerate rot, while board friction causes severe warping, buckling, and surface cracking.
Green Shield rigorously trains our crews to execute precise, uniform gapping across every element of a project. From deck framing and deck boards to staircases and picture-frame accents. This practical engineering prevents costly structural failures, delivers a low-maintenance outdoor living space, and ensures a beautifully finished deck that is built to last.
