Winter Maintenance Tips for Composite Decks
Composite is low-maintenance — but Massachusetts winters still deserve a plan.
Remove snow carefully
Shovel with the grain of the boards. Leave a thin layer to protect the surface if you're using anything abrasive.
Avoid metal shovels
Plastic or rubber-edged shovels only. Metal can scratch the cap.
Use manufacturer-safe ice melt
Calcium chloride and rock salt aren't equal — read the deck manufacturer's guide before choosing.
Keep drainage clear
Clear the gaps between boards so water and melt don't pool.
Watch for slippery areas
Composite can get slick when wet or icy. Non-slip mats help at stair tops and doorways.
Spring inspection
Walk the deck after the last thaw. Look for anything that moved.
Clean debris
Leaves and dirt in the board gaps hold moisture. Blow them out in fall and after storms.
When to call a specialist
Movement, loose railings, or exposed hardware are worth a professional look.
