Second Opinion on a 'Rotting Deck' in South Medford

A South Medford homeowner was quoted a full deck rebuild. A second opinion found only the ledger board had rotted. See what we found — and saved. Call us.

A homeowner in a quiet South Medford subdivision called us on a Tuesday afternoon. They were frustrated — and honestly, a little rattled. A contractor had walked their backyard deck, poked around for maybe twenty minutes, and handed them a verbal quote for a full tear-out and rebuild. The number was significant. The explanation was vague: "widespread rot, the whole thing's got to go."

Before signing anything, they decided to get a deck building second opinion. That call made a real difference.

The Call: "Is My Whole Deck Really That Far Gone?"

The home is a 1990s single-story ranch in a South Medford neighborhood with mature oaks lining the back fence and a classic sliding glass door opening onto an attached deck. It's the kind of backyard setup that gets used hard — summer barbecues, morning coffee, kids and dogs tracking in and out.

The deck itself was maybe twelve by sixteen feet of pressure-treated framing with composite decking boards. Nothing flashy. Solid and functional, the way a good deck should be.

When the homeowner described the original contractor's findings, a few things stood out. The word "widespread" kept coming up, but when pressed, the homeowner said the contractor had mostly focused on the area where the deck attached to the house. The decking surface looked fine to them. The posts looked fine. The framing out toward the yard looked fine. So why was the whole thing being condemned?

That's exactly the kind of situation where a deck building second opinion earns its keep.

What We Found On Site

We showed up the next morning with a probe, a moisture meter, and no assumptions.

The decking boards? Solid. We walked every plank. No soft spots, no bounce, no discoloration beyond normal weathering. The structural posts were planted firmly, and the beam-to-post connections were tight. Out in the yard, this deck had plenty of life left.

The story changed at the house wall.

The ledger board — the pressure-treated lumber that bolts directly to the house's rim joist and carries the inside edge of the deck — was soft. Not just surface-soft. The probe sank in. Moisture readings were elevated well into the framing. When we pulled back the siding slightly to get a look at the flashing condition, we found the problem immediately: the step flashing and drip edge at the ledger connection were either missing entirely or had been installed incorrectly — lapped the wrong direction, with no positive drainage away from the wall.

For years, every rainstorm had been doing the same quiet thing. Water ran down the house wall, found the gap at the ledger, and wicked straight into the rim joist. No visible leak inside the house. No puddle on the deck. Just slow, invisible moisture accumulation in a piece of framing that was never meant to stay wet.

The rot was real. But it was confined — limited to the ledger board and a section of the rim joist behind it. The rest of the deck was structurally sound.

A full tear-out was never necessary.

How We Fixed It

The scope of work was surgical. Here's what the job actually required:

1. Remove the ledger board. We detached the existing ledger carefully to expose the rim joist behind it. The affected section of rim joist had surface decay but the damage hadn't penetrated to the floor framing inside. We treated the exposed wood with a penetrating borate solution to stop any residual fungal activity and let it dry thoroughly before closing things back up.

2. Install proper flashing. This is the step that was skipped the first time — and the step that would have prevented all of this. We installed step flashing integrated with the house wrap, then a metal drip edge angled to direct water away from the wall. Every layer lapped correctly, shingle-style, so water has one direction to travel: away from the structure.

3. Replace the ledger with code-compliant pressure-treated lumber. The new ledger went in with the correct fastener pattern — structural lag screws at the specified spacing, into solid framing. In Oregon, deck ledger connections have to meet IRC standards, and we pulled the permit to make sure the work was inspected. Licensed, bonded, and insured in OR — that's not a detail we skip.

4. Reconnect the joist hangers and deck framing. Once the new ledger was set and inspected, we reattached the existing joist hangers and confirmed every connection was tight. The decking boards went right back down. From the outside, the deck looks exactly as it did before — because structurally, it's the same deck. Just properly flashed and properly attached.

The total cost was a fraction of what a full rebuild would have run. The homeowner kept their deck, kept their weekend plans, and didn't have to live through a two-week construction project.

What to Watch For: The Ledger Is Your Deck's Highest-Risk Point

If there's one thing to take away from this job, it's this: where your deck meets your house is the most vulnerable spot on the entire structure. It's a horizontal surface where two building assemblies join, and if the flashing isn't right, water will find its way in every single time it rains.

The frustrating part is that ledger rot is invisible for years. It happens behind the siding, inside the wall assembly, in a place you'd never think to look. By the time you notice soft wood or discoloration near the house wall, the damage has usually been building for a long time.

A few things worth watching:

Soft or spongy decking boards near the house wall. This is often the first visible sign that moisture is working its way out from the ledger area.
Discoloration or staining on the siding just above the deck. Water tracking down the wall and pooling at the ledger connection often leaves a shadow or streak.
Any gap between the ledger and the house wall. Even a small separation can let water in.
Decks on homes built in the 1980s and 1990s. Flashing standards and installation practices have improved significantly. Older decks are more likely to have inadequate or missing flashing.

If you're seeing any of these signs, don't let anyone quote you a full rebuild before someone has actually looked at the ledger connection. A deck building second opinion costs you nothing but a morning — and it might save you thousands.
