Decks · Roy, Washington
Decks in Roy should account for the spaces between boards as part of the selected system. A tightly drawn rendering is not a reason to eliminate gaps that the product needs for drainage and movement.
Evergreen Home Pro helps you compare the intended finished appearance with the installer’s product-specific details. Ask how side, end and wall-adjacent gaps are established for the actual boards.

Deck building
Trex explains that spacing supports drainage and accommodates material movement, with installation conditions affecting some gap requirements. Have the installer use the current instructions for the actual product rather than copying a single gap from another deck.
Keep the board product and profile with the layout being reviewed.
Ask about board sides, board ends and locations against solid objects instead of treating them as one identical detail.
Have the provider follow the selected system’s current requirements for the work being performed.
Before work begins
Confirm the proposed deck structure with the city and keep the selected surface system consistent with the plans. A board-spacing choice does not establish structural approval.
Ask the provider to explain how the specified surface and fasteners fit the reviewed arrangement; do not use a visual sample as a construction instruction.
Have the installer retain the gaps required by the selected product and conditions.
Ask how the actual instructions distinguish the different locations.
Use the supplied system’s current instructions and the qualified provider’s assessment.
Share the intended material and layout so the estimate can explain the finished spacing and installation scope.
