Deck maintenance schedule by material

What’s inside the PDF

• Year 1 / Year 5 / Year 10 milestones for all four major deck materials
• Spring inspection routine — fasteners, ledger, flashing, joist hangers
• Fall close-down routine — clearing, sealing, freeze-thaw prep
• Cleaner + sealant recommendations by material
• Failure signs that mean it's time to call a contractor instead of DIY-ing

How to use it

• Pin to the inside of the garage door — the routine fails when it's out of sight
• Schedule the spring inspection for the first weekend the deck is dry enough to walk barefoot
• Cross-reference the year column with your build year to know what cycle you're on
• Photograph any flagged failure signs and email a contractor before they propagate

Why this template exists

Deck maintenance is mostly about catching small problems before they become structural ones. The schedule walks through the practical routine I've watched homeowners actually follow over a decade — not the manufacturer marketing schedule, which assumes you do everything perfectly. Pressure-treated decks need the most attention (annual cleaning, sealant every one to two years, board replacement on the cuts that catch the worst weather around year ten). Cedar weathers faster than PT and needs refinishing every two to three years if you want to keep the colour. Composite and PVC need washing twice a year and otherwise nothing. The failure-sign section at the bottom is the part to actually pin up — it tells you when a small problem (rust streak under a fastener, a soft spot near the ledger, a wobble in a stair stringer) is the kind of small problem that gets dramatically bigger if you ignore it for a season.
