If you want to prepare a vinyl deck for spring, the goal is simple: get it clean and
confirm it’s draining and sealed the way it should—before patio season turns into “why is this corner always wet?”
season.
Vinyl decking is built for low maintenance, but winter can leave behind gritty debris, algae/mildew specks, and
clogged drains that keep moisture hanging around longer than invited guests. The good news: most spring prep is a
quick routine—plus one short inspection that can prevent expensive callbacks later.
Why spring prep matters for vinyl decking
Spring mess is sneaky. You’ll usually see the obvious stuff (leaves, pollen, dirt). The less obvious issue is
moisture—especially in shaded areas and around drains, railings, and wall junctions. Mold and
mildew are basically a moisture-management problem wearing a disguise.
The EPA puts it plainly: moisture control is the key, and mold on hard surfaces can often be removed by scrubbing
with detergent and water, then drying completely.
