Deck Ledger Repair in Medford, OR | Bear Creek Estates

The Morning After the Party

The gathering had gone well. Good weather, a full deck, the kind of evening that makes a craftsman home in the Bear Creek Estates area feel like exactly the right place to live. Then the next morning, in the flat light before coffee, the homeowner noticed it: a gap — roughly three-quarters of an inch — running along the line where the deck frame met the house siding.

The deck felt solid underfoot. No bounce, no sway. But that gap wasn't there before. And with the deck sitting nearly five feet off grade on the downhill side of the lot, "felt solid" wasn't going to be enough reassurance.

They called us before 8 AM. That was exactly the right move.

This is a same-day service situation. A deck ledger pulling away from the house is one of the leading causes of sudden deck detachment nationally. It doesn't always give you a warning bounce or a creak. Sometimes the connection just lets go. We told them to keep everyone off the deck until we arrived, and we were on site within the hour.

What We Found on Site

Our first job on any emergency call like this is to assess load safety before we touch anything. We looked at the full ledger run, checked the lag bolt heads for movement, and probed the siding and framing in the affected zone.

What we found was a textbook case of a code-deficient original installation — the kind of detail that was common on decks built before modern IRC deck attachment requirements became standard practice in this region.

The ledger board had been lag-bolted directly through the vinyl siding with no flashing and no standoff spacer. That means for years — likely since the deck was first built — water had been wicking behind the ledger every time it rained. The siding trapped moisture against the rim joist. The rim joist, the framing member the lags are supposed to bite into, had rotted from the inside out.

By the time we pulled back the siding in the affected section, the wood behind it was dark, punky, and soft. The lag bolts weren't holding in solid lumber anymore. They were threading through material that had the structural integrity of wet cardboard. The deck was essentially hanging on friction and habit.

This is the scenario that keeps deck builders up at night. The deck looked fine from the surface. The rot was completely hidden. And a full deck load — a crowd of people on a summer evening — had been stressing that connection all night.

We documented everything with photos, walked the homeowner through what we were seeing, and outlined the scope of work before we touched a fastener.

How We Fixed It

Step one: temporary shoring. Before any structural work began, we installed temporary posts and beam supports under the deck frame to carry the load independently of the ledger. This is non-negotiable when you're pulling a ledger on an elevated deck. The deck stays up; we work safely underneath.

Step two: permit pull. Structural deck repair in Medford requires a permit. We pulled one with the City of Medford before the repair work started. We're licensed, bonded, and insured in OR, and our license number is on every quote and every truck. Skipping the permit on structural work like this isn't a shortcut — it's a liability that follows the house.

Step three: rim joist repair. We removed the rotted section of rim joist and sistered in new pressure-treated lumber, properly fastened and tied back into the existing floor framing. Solid, inspectable, done right.

Step four: full ledger replacement. The old ledger came out entirely. The new ledger went in with correctly installed flashing — metal flashing lapped up behind the house wrap and down over the top of the ledger, with a proper drip edge detail to direct water away from the framing. We used through-bolts in a pattern that meets current IRC deck attachment requirements, with appropriate spacing and staggering for the deck's tributary load. No lag bolts threading into rot. No water traps built into the connection.

Step five: siding repair and cleanup. We reinstalled siding over the repaired zone, sealed the penetrations, and hauled off all demo material. The punch list was clean before we called for inspection.

The repair passed inspection. The temporary shoring came down. The deck was back in service.

What to Watch For on Your Own Deck

This job is a good reminder that deck ledger failure is almost always a slow, hidden process — until it isn't.

Here's what we tell every homeowner after a job like this:

Once a year, walk the line where your deck meets the house. Get close. Look for any gap between the ledger or the siding and the house wall. Look for staining, bubbling paint, or soft spots in the siding in that zone. Press on the siding with your thumb — it should feel firm. If it flexes, there's a problem worth investigating.

Check the lag bolt heads or through-bolt hardware. Any rust streaking down from the fasteners is a sign moisture is getting in. Any movement in the bolt when you push on the deck frame means the connection has already lost its bite.

Flashing is not optional. If your deck was built before modern flashing details became standard — or if you've never seen documentation that flashing was installed — a licensed deck inspection before the next heavy rain season is money well spent. The inspection cost is nothing compared to the liability of a deck ledger pulling away from the house with people on it.

Elevated decks carry more risk. A deck that's two feet off grade is an inconvenience if it fails. A deck that's five feet off grade on a hillside lot is a serious injury event. The height changes the stakes entirely.

Bear Creek Estates sits on rolling terrain. A lot of homes in that neighborhood have elevated rear decks on the downhill side — exactly the configuration we saw here. If that describes your home, this story is worth a few minutes of your time outside with a flashlight.
