Deck repair, done right and done soon
A lot of builders chase big new-build jobs and let repair calls go to voicemail. We don't. In the Pacific Northwest, a soft board or a wobbly railing isn't a someday problem — it's a safety issue, and the wet season is always working against you. We reply the same day and we show up.
Clark County decks live a hard life. Our climate hands them roughly nine months of rain, damp air, and shade, then a few months of strong summer UV. That cycle — wet, dry, wet again, with freeze-thaw mixed in — is exactly what breaks down wood, loosens fasteners, and feeds the fungus that causes dry rot. Below is a straight, detailed look at how decks fail here, how to catch it early, and how we fix it for good.
Why decks rot so fast in the Pacific Northwest
“Dry rot” is a misleading name — it's actually caused by wood-decay fungi that need moisture to live. Once wood stays above about 20% moisture content for long enough, fungal spores take hold, feed on the wood fibers, and leave behind the crumbly, cracked, weakened material everyone calls dry rot. In a bone-dry climate it's rare. In Clark County, it's the single most common reason decks fail.
Three local factors make it worse than almost anywhere else:
- Persistent moisture. Vancouver, Camas, and the rest of the county see long, wet winters and heavy morning dew much of the year. Wood rarely gets a chance to fully dry out.
- Shade and tree cover. Douglas firs and big-leaf maples keep decks shaded and drop needles and leaves that trap water against the boards and pack into the gaps. North-facing decks are the worst offenders.
- Freeze-thaw and summer UV. Winter freeze-thaw cycles pry open checks and cracks; summer sun then dries and splits the surface. Every crack becomes a new place for water to soak into the vulnerable end grain.
This is also why we so often recommend composite or Trex when boards are replaced — it simply doesn't rot. But a well-maintained wood deck can last decades here if the water is managed and the rot is caught early.
Where dry rot starts on a deck (and what we check first)
Rot almost never starts in the open, sun-and-wind-exposed middle of the deck. It starts in the hidden, slow-drying connection points — the exact places that also hold the structure together. When we inspect a deck, this is the order we check:
- The ledger board & flashing. Where the deck attaches to the house. Bad or missing flashing lets water run behind the ledger and into the rim joist of your home — this is the #1 cause of catastrophic deck collapses and hidden water damage to the house itself. We check it on every single repair.
- Post bases & footings. Posts in or near ground contact wick up moisture and rot from the bottom, often invisibly. A post that looks fine at eye level can be mush at the base.
- Joist ends & beam pockets. Cut end grain soaks up water like a straw. Joist ends resting on or notched into a beam are classic rot pockets, especially where debris collects.
- Stair stringers & landings. Stairs touch the ground, take the most foot traffic, and shed water poorly — a very common failure and fall point.
- Under the railing posts. Railing posts bolted through the deck create holes that trap water, quietly rotting the framing they're attached to — which is why a wobbly railing is often a structural warning, not just a loose bolt.
- Board ends & fastener holes. Every cut end and every screw hole is an entry point. Cupped, cracked boards funnel water straight in.
Warning signs: a 5-minute homeowner inspection
You can catch most problems yourself before they get expensive. On a dry day, walk your deck and look (and press) for these:
- The screwdriver test. Press a screwdriver or key into suspect boards, joist ends, post bases, and stair stringers. Sound wood resists; rotten wood is soft, spongy, or crumbles. This is the single most useful test.
- Soft, spongy, or bouncy spots underfoot — a sign the board or the framing beneath it has lost strength.
- Dark staining, discoloration, or a musty smell — early fungal activity, often before the wood feels soft.
- Mushrooms, moss, algae, or fungal growth on or under the deck — proof that moisture is sitting long enough to grow things.
- A deck that wobbles, sways, or feels bouncy — possible framing, post, or ledger movement. Take this seriously.
- Gaps opening at the ledger or the deck visibly pulling away from the house — stop using the deck and call us.
- Rusted, popping, or backing-out fasteners and rusty streaks — water has been in the connection for a while.
- Cracked, checked, or cupped boards and cracked posts — the openings that let the next round of water in.

When it's a safety emergency
Most rot is a “fix it this month” problem. But some signs mean stop using the deck now:
- The deck is pulling away from the house or you see a widening gap at the ledger.
- Railings or guardrails are loose, leaning, or give way when leaned on — especially on an elevated deck.
- Posts are cracked, tilting, or rotted at the base, or the deck sways side to side.
- Stairs are soft, separating, or moving underfoot.
Elevated deck failures cause serious injuries every year, and they tend to happen when the deck is most loaded — a summer gathering. If you see any of the above, keep people off it and reach out right away. We prioritize genuine safety issues.
Repair or replace? An honest framework
We'd rather earn your trust with a fair repair than oversell you a rebuild. Here's the same logic we use on site:
- Repair makes sense when the damage is localized — some rotten boards, a failing railing, a few compromised joists, worn stairs — and the core structure (footings, posts, beams, ledger) is sound.
- Replacement is the smarter spend when rot is widespread, the framing or footings are undersized or failing, the ledger was never flashed correctly, or you'd be pouring money into a deck that's simply at the end of its life.
- The gray area — when repairs approach roughly half the cost of a rebuild, replacement usually wins on value, and it lets you upgrade to composite and reset the clock. We'll show you the numbers both ways.
Either way you get a straight recommendation and a written quote. If replacement is the right call, here's how our deck replacement works, and here are real Clark County cost ranges.
How we repair a deck — and stop the rot coming back
Anyone can screw a new board over rotten framing. That's not a repair, it's a cover-up. We fix the cause, not just the symptom:
- Diagnose the source. We find where the water is getting in — flashing, drainage, ground contact, trapped debris — because if we don't fix that, the rot returns.
- Replace compromised structure with properly sized, pressure-treated or rot-resistant material, correctly fastened and connected to code.
- Re-flash the ledger when needed with proper flashing and fasteners — the connection that protects both the deck and your house.
- Improve the water management — correct post-to-concrete standoffs, better drainage, gapping, and (on elevated decks) under-deck drainage so the space below stays dry.
- Re-deck or reseal the surface — new boards (often composite), fresh fasteners, and on wood, a proper clean-and-seal.
Preventing future dry rot
After a repair, a few things keep it from happening again: keep gaps and joist tops clear of needles and leaves, don't let planters or mats trap water on the boards, reseal wood decks on schedule, keep soil and mulch away from posts and framing, and make sure downspouts aren't dumping onto the deck. When boards need replacing anyway, switching to composite ends the rot cycle entirely.
Winter storms & seasonal deck damage
Clark County winters don't just cause slow rot — they cause sudden damage too. We repair storm and seasonal problems including:
- Fallen limbs and tree debris that crack boards or railings — common on our wooded lots in Camas, Brush Prairie, and Felida.
- Wind damage to railings, lattice, and covers, especially on exposed Gorge-facing decks near Washougal.
- Freeze-thaw splitting that opens boards and posts to new water intrusion.
- Standing-water and drainage failures after heavy rain that accelerate rot if not corrected.
Caught something after a storm? The sooner it's sealed up, the less water gets into the structure over the wet months. Send photos and we'll get you a same-day answer.
What deck repair costs in Clark County
Repairs range widely because “deck repair” covers everything from swapping a few boards to rebuilding rotted framing:
- Small jobs — a handful of boards, a railing re-anchor, popped fasteners, minor stair fixes — are typically a modest one- to two-day repair.
- Mid-size jobs — multiple joists, a section of decking, stair rebuilds, ledger and flashing correction — take more time and material.
- Structural repairs — beams, posts, footings, or widespread rot — are the point where we'll compare the repair cost honestly against a replacement.
We quote repairs honestly and tell you when replacement is the better value. See our full Deck Cost in Clark County guide for material and per-square-foot ranges. Every repair is backed by our written workmanship warranty — if a repair we made fails on us, we come back and fix it.

FAQ
Deck Repair questions
What deck repairs do you handle?
Dry rot and soft boards, loose or wobbly railings, sagging or bouncy framing, popped fasteners, damaged stairs and landings, and structural fixes to joists, beams, posts and footings.
How fast can you look at my deck?
We respond to repair requests the same day through the form. Safety issues like a loose railing or rotten board move to the front of the line.
Is my deck safe or does it need replacing?
We'll give you an honest assessment. If a repair makes it safe and adds years, we repair it; if the structure is compromised, we'll show you why and quote a replacement.
Why is my deck wobbly or bouncy?
Usually undersized or over-spanned joists, missing blocking, loose ledger connections, or failing posts/footings. We diagnose the cause instead of just adding a nail.
What causes dry rot on PNW decks?
Constant moisture — trapped water at the ledger, poor flashing, ground contact, and end-grain soaking up rain. Cedar and pressure-treated wood both rot eventually without maintenance.
Can you replace just a few boards?
Yes. We can swap damaged boards, though on older wood decks matching color is tough — we'll advise whether spot repair or re-decking makes more sense.
Do you fix decks other contractors built?
Yes — much of our repair work is correcting someone else's cut corners or a previous owner's DIY. We stand behind our repairs in writing.
My railing is loose — is that dangerous?
Yes, a loose railing is a serious fall hazard, especially on elevated decks. It's one of the most common and important repairs we do; don't put it off.
Can you repair the ledger and flashing?
Yes, and it's critical work — a bad ledger/flashing connection causes both deck collapses and water damage to your house. We repair and flash it to code.
Do you repair deck stairs?
Yes — we rebuild loose, rotted or out-of-code stairs and landings, including stringers, treads and handrails.
Can you fix a deck that's pulling away from the house?
Yes. A deck separating from the house is a ledger failure and a safety emergency — stop using it and contact us right away. We'll re-anchor it correctly.
Do deck repairs need a permit?
Simple like-for-like repairs often don't, but structural changes usually do. We'll tell you which applies and handle any permit needed.
Can you treat or prevent future rot?
We fix the source (drainage, flashing, ground contact), use rot-resistant materials, and can recommend sealing schedules for wood — prevention is cheaper than repair.
How much does deck repair cost?
It ranges from a small job for a few boards or a railing to more for replacing rotted joists or footings. We quote honestly and flag when replacement is the better value.
Should I repair or replace an old wood deck?
If damage is localized, repair. If rot is widespread or the structure is undersized/failing, replacement is safer and often cheaper long-term. We give you the honest call.
Can you make my deck code-compliant?
Yes — we bring railings, stair rise/run, guard height and structural connections up to current Clark County code, which matters for safety and resale.
Do you repair composite decks?
Yes. Composite surfaces rarely rot, but framing underneath can, and boards or fasteners can be damaged. We repair both the surface and the structure.
How long does a repair take?
Many repairs are a one- to two-day job; larger structural repairs take longer. We'll give you a clear timeline with the quote.
What's your warranty on repairs?
We back our repair work in writing. If a repair we made fails on us, we come back and fix it — the No-Ghost Guarantee applies to repairs too.
How do I request a repair?
Send photos and your town through the quote form. We'll respond the same day, even on weekends.
