Ohio Deck Maintenance Schedule: Annual Checklist for Wood Decks

Spring (April – May): Inspect and Clean

Spring cleaning removes winter grime, mold, mildew, and the gray surface oxidation that develops on weathered wood. Use a deck cleaner appropriate for your stain type and a stiff brush or low-pressure washer. Aggressive pressure washing above 1,500 PSI can raise wood grain and damage the surface — keep it controlled.

Clean the deck:

• Walk the entire surface — feel for soft or spongy spots that indicate rot
• Check all ledger board connections to the house — the most structurally critical point
• Test railings by pushing firmly — any movement means loose hardware or rotted posts
• Look under the deck at joists and beams for moisture damage or insect activity
• Check deck boards for cupping, cracking, or splitting caused by winter freeze-thaw
• Inspect fasteners — popped nails and backed-out screws are tripping hazards

Late Spring (May – June): Stain or Seal If Needed

Surface prep — cleaning, brightening, and light sanding — is as important as the stain itself. Stain applied to a dirty or oxidized deck won't penetrate and will peel prematurely.

Does your deck need staining?

• Semi-transparent stain: shows wood grain, best on decks in good condition
• Solid stain: covers imperfections, better for older or weathered wood
• Clear sealer alone: minimal protection, not recommended as a standalone treatment in Ohio

Summer: Protect During Peak Use

Summer is when your deck works hardest. A few habits protect the surface during peak season:

• Use furniture pads under chair and table legs to prevent scratches that hold moisture
• Don't leave wet rugs, towels, or doormats sitting on wood — they cause staining and rot
• Clear debris from between deck boards after storms — leaves and organic matter accelerate decay
• Move potted plants occasionally — standing water in saucers stains and rots wood beneath them

Fall (October): Pre-Winter Prep

Before the first hard freeze, spend 30 minutes on these tasks:

• Sweep and blow leaves off the deck before they decompose and stain the wood
• Clear debris from between deck boards with a putty knife or deck gap tool
• Tighten any loose hardware — fasteners contract in cold and can loosen over time
• If the deck wasn't stained this spring, apply a penetrating water repellent before freeze season
• Note any problem areas to address next spring — don't attempt staining in cold temperatures

When to Call a Professional

DIY maintenance handles the surface. These conditions require professional assessment:

• Soft or spongy deck boards or framing: active rot, components need replacement
• Ledger board movement or visible separation from the house: structural issue, deck may be unsafe
• Post rot at ground level: posts need replacement before the deck is safe to use
• Widespread surface cracking: deck may need professional sanding, brightening, and staining
• Joist hanger failure or heavy corrosion: framing hardware needs replacement
