7 Deck Maintenance Jobs You're Forgetting Every Spring

TL;DR: Most deck failures start at the ledger board where it meets the house, not the boards you can see from your patio chair. Spend 45 minutes each spring checking flashing, fasteners, footings, and railings before the deck carries a summer's worth of grill parties and furniture weight. Skip it, and the average repair after a partial collapse runs $3,000 to $8,000 versus $100 in hardware for a proactive fix.

You power-wash the deck, maybe restain it, and call it done. But the parts that actually fail — the ledger connection, the hidden fasteners, the footings under the posts — never get a second look until something moves underfoot. Here are the seven jobs that get skipped every single spring, and why the ones you can't see matter more than the ones you can.

Okoniq Property Hub logs every deck check with photos and dates, so you're not guessing whether last spring's inspection actually happened.

Is the ledger board still attached correctly?

The ledger board is where your deck bolts into the house rim joist, and it's responsible for roughly half of all deck collapses reported by the Consumer Product Safety Commission over the past two decades. Water gets trapped behind the ledger when flashing fails, rotting the framing from the inside while the surface boards look fine.

Pull back any loose flashing in spring and look for dark staining, soft wood, or gaps where the ledger meets the house. If you see daylight between the ledger and the siding, or the lag bolts are rusted and loose, that's a structural issue, not a cosmetic one. Poor water management around the house is often the root cause, and the same principle shows up with downspout mistakes that send water into your basement — water finds the weakest connection point and stays there.

Are the joist hangers and fasteners actually holding?

Check every visible joist hanger for rust, bent tabs, or missing nails, because galvanized hangers installed before 2005 often used undersized fasteners that back out over time. Crawl underneath if you can and look up — this is the inspection homeowners skip most because it means getting dirty.

Press on each hanger by hand. If it flexes or you can wiggle a nail with two fingers, replace it with a joist hanger nail rated for that hanger, not a generic 16d nail bought at the hardware store. A box of proper hanger nails costs under $10 and takes 20 minutes to redo a dozen connections.

Do the posts and footings still bear weight evenly?

Rot at the base of a post or a footing that's shifted from frost heave will show up as a deck that feels slightly springy on one side. Push against each support post at ground level — any give, or wood that's spongy when you press a screwdriver into it, means the post base is compromised.

Footings poured less than 12 inches below grade in freeze-thaw climates move a little every winter, and after 8 to 10 years that movement adds up to visible tilt. Compare what you're dealing with:

| Concern | Minor / Cosmetic | Structural / Fix Now | |---|---|---| | Post base | Surface graying, no give | Soft wood, visible cracking | | Footing | Slight settling, deck still level | Post leaning more than 1 inch | | Railing post | Loose cap, tight base | Base moves when pushed |

If your footing is undersized or shallow, that's a job for a contractor who pulls a permit, not a spring DIY fix.

Are the railings still rated to stop a fall?

Railings need to hold 200 pounds of lateral force per code, and most people never test that until someone leans on one. Grip the top rail and push firmly side to side and down. Any wobble at the post connections means the lag bolts have backed out or the post itself has split.

Check baluster spacing too — anything wider than 4 inches is a fall risk for small children and often fails inspection if you ever sell. If your deck has an electrical outlet for string lights or a grill, spring is also the time to confirm it's GFCI-protected; outdoor circuits near water and metal railings need that protection, similar to the safety upgrade covered in 2-prong vs 3-prong outlets and how to upgrade safely.

What's the fastest way to prioritize these jobs?

Start with anything that affects structural load — ledger, joist hangers, posts, footings — before you touch anything cosmetic like staining or gap cleaning. A deck can look freshly stained and still fail if the ledger flashing is rotted behind it.

Two more jobs worth adding to the same spring visit: clear debris from between deck boards so water drains instead of pooling against the wood, and confirm the ground under the deck still slopes away from the house. If water pools under there, you'll see the same staining pattern that shows up when downspouts dump water in the wrong place — the fix is usually regrading, not more sealant.

FAQ

How often should a deck be inspected?

Once a year at minimum, ideally in spring before heavy summer use begins, plus a quick check after any winter with heavy snow load or ice.

How much does it cost to fix a rotted ledger board?

A ledger replacement with new flashing typically runs $800 to $2,500 depending on deck size and siding access, far less than the $3,000-plus cost of repairing damage after a partial collapse.

Can I inspect my own deck or do I need a professional?

You can handle the visual and hand-pressure checks described here yourself in under an hour. Call a licensed contractor if you find soft wood at the ledger, a leaning post, or any structural movement you can't explain.

What's the lifespan of a typical wood deck?

A pressure-treated wood deck lasts 10 to 15 years with regular maintenance, while the ledger connection and footings often need attention sooner, around the 7 to 10 year mark, since they take on the most water exposure.

Does deck maintenance affect homeowners insurance?

Some insurers ask about deck condition during underwriting or after a claim, and documented annual inspections can support your case if you ever need to prove the structure was maintained.
