Not always the house itself
Rot is a water problem before it is a carpentry problem, and in Brush Prairie that water lands on ground with no city government watching over it. This is unincorporated Clark County along Route 503, roughly 48 to 50 inches of rain a year, and parcels zoned R-5 or larger, five acres and up, built for distance between neighbors rather than density. Most properties here run on a private well and septic system instead of city water and sewer, and a good share also carry a second or third building, a shed, a detached garage, a barn, that one owner put up on their own schedule with far less oversight than the house itself ever had. We get called out to the main house about as often as we get called to whatever is standing behind it. Either way the work is the same: trace the water to where it actually got in, cut back past the last soft fiber, and rebuild whatever carries load before any siding goes back on.

On a parcel that holds more than one building, water does not limit itself to whichever roofline you happen to be living under. These are the spots we end up opening most, on the house or on whatever else is standing on the property:
The first boards to go soft: corner boards at the base, the casing around windows and doors, belly bands and water tables on the house itself. A shed, barn or detached garage nearby often has no trim at all to go soft first, just bare board siding that was never meant to carry five decades of Clark County weather on its own.
Soft decking, the joists and beams underneath it, and the ledger tying the whole deck back to the house, the connection that usually gives out first regardless of who built it or when. Out here a deck might be original to the house, or it might be something a previous owner bolted on themselves one weekend without pulling a permit, and the ledger bolt pattern usually tells us which the moment the siding comes off.
Rim joists, sill plates, wall studs and post bases pulling moisture up out of ground that drains to roadside ditches and natural swales rather than any storm sewer, which is simply how water moves on acreage zoned for five acres and up. We find it most in the crawlspaces under additions a previous owner tacked onto the house over the years, one project at a time rather than all at once.
Flashing that gave out years ago quietly sends rain behind the trim with every storm since, on the house as readily as on a shed or garage that never had a flashing detail installed in the first place. A detached structure an owner put up without one at all can actually hide this longer, since there is no finished interior ceiling underneath to show a stain before the framing is already soft.
A supply line or a shower pan weeping quietly for months softens the subfloor underneath long before a tile ever cracks, the same whether that bathroom is part of the original house or was plumbed into an addition built sometime after.
Tell us what you are looking at and attach a photo or two. That is really all a first message needs to be. We read everything that comes in before 5pm the same afternoon, whether you are off Route 503 itself or out toward Hockinson and Meadow Glade, and on the rare job that is not actually ours to take, you will hear that from us too rather than us stringing you along.
On rot work this is the only proof that means anything. A finished photo shows a wall. A pair shows what was behind it.
Drag the handle. From the opened shower wall, framing dark with old water, to the finished walk-in shower with its glass panel and tiled half wall.
Before After A homeowner can usually spot a soft windowsill or a bubbled patch of paint from across the yard, but that visible spot is simply where the decay finally ran out of material to work through, not the point where water actually broke in. Underneath, rot runs the length of the grain hidden by whatever paint or siding sits over it, and on a shed or barn with no record of what the owner originally built into the walls, that unseen stretch can run considerably longer than on the house, where the construction is at least generally known. Any number attached to a photograph is really a number attached to a hunch, and that hunch tends to resurface as a change order the day the wall actually comes open.
That is exactly why nobody here writes a final number without standing at the actual wall first. Everything we can verify without opening anything becomes a locked price on the estimate. Everything that depends on what the open wall reveals gets flagged as its own separate item, one that stays untouched until you have looked at photos and said to move forward. Nothing about which figure is guaranteed is left for you to guess at, since it is spelled out in writing before a single additional cut happens.
A five-acre lot in Brush Prairie often holds more than one building, and no two of them necessarily went up in the same decade or to the same standard. A detached garage or a barn built by a previous owner with whatever lumber happened to be on hand does not fail the same way, or on the same timeline, as the main house forty feet away, which means a rot call out here is rarely about just one roofline.
Cutting the rot out is the easy half. The half that matters on a property with more than one building is matching the material to whatever is actually there, which on a shed or barn nearby might be nothing like what is on the house.
We start by matching whatever is already on the structure in question, because the best repair is the one nobody can point to later. If the house still carries its original cedar corner boards, cedar is what goes back, cut to the same profile. A shed or barn nearby is a different question entirely, since an owner working alone may have sided it in whatever was on hand at the time, plain pine, recycled lumber, even plywood siding, and matching that means working from what is actually on the wall rather than assuming it matches the house forty feet away.
Cedar and redwood resist decay because of natural preservatives packed into the dense heartwood, something a young, fast-grown board sold today simply does not carry as much of. A budget option like primed finger-jointed pine takes a brush nicely and costs little, but give it steady dampness and it softens within a handful of seasons, so it has no business near grade or at the bottom edge of a trim run. Where a joint has already failed once, we switch to a manufactured product instead, cellular PVC or fiber cement, materials with no wood fiber in them at all to feed the rot a second time.
Framing lumber follows a separate standard no matter which building it is in. Any piece landing on a foundation or sitting low to the dirt gets installed pressure-treated, full stop, because that is likely the exact failure that started the problem to begin with, plain fir resting against damp ground. A sistered joist or a fresh stud is Douglas fir, sized to actually bear the load the old piece carried, not merely cut to close the hole.
Hardware gets more attention here than people expect it to. Today’s treated lumber carries enough copper in it to chew through an ordinary zinc screw inside one wet season, leaving a rusty bleed down the face of a board that no amount of paint will ever cover again, so stainless or heavy hot-dip galvanized fasteners are the only kind that touch treated stock or cedar on our jobs.
One habit decides more than the paint brand ever will: every piece gets a coat of primer on all sides, the cut ends most of all, before it is ever nailed into place. An unsealed end pulls moisture in far faster than a flat painted face does, and whether that single step actually happened is usually the real difference between a repair that holds for twenty years and one that does not, on the house or on whatever is standing behind it.
What a rot repair here actually costs rests on four separate factors, and a screwdriver is all it takes to answer the first two yourself before we ever show up.
Does the piece actually bear weight? Trim, a water table, a bottom course of siding, none of that holds a structure up, so a bad length of it is a lost afternoon and nothing worse. A rim joist, a sill plate, a post base or a deck ledger is a different matter on either the house or a shed nearby, because something is actually resting on it, which means temporary shoring, sound replacement lumber, and a permit filed with Clark County Building Safety before the wall closes back up, even on a structure a previous owner built without ever pulling one. The lumber is rarely what sets the price. Getting a loaded member out safely, without anything shifting, is what does.
How far back does the soft wood actually go? Push a screwdriver into the board every couple of inches, starting at the obvious trouble spot, and keep testing outward until it meets real resistance again, then test a full twelve inches past that point anyway. Decay spreads inside the fiber long before anything shows outside, and stopping at the edge of what you can see is the most common reason a repair has to be done twice.
Does a consolidant belong here instead of new lumber? Occasionally, and we say so plainly when it applies. A good filler can save a shaped piece nobody mills anymore, a porch post, an old sash, a run of trim specific to whichever decade a building went up, provided the rot sits in a contained pocket rather than running clean through. None of that applies to anything load-bearing, and it is never a shortcut around opening a wall that genuinely needs it.
And what is actually above the damage? That answer decides whether a fix lasts. Out here it is as often a gutter nobody has cleaned in years on an outbuilding as it is a missing kickout on the house itself, and either way we trace that source and close it before any new wood goes in, priced on the same estimate, because lumber installed under a leak that is still running just gets paid for twice.
There is no way to hand you one number before we have actually opened the wall, because the real driver is how much rot is hiding, not the size of the house or which building it happens to be on. A few things hold true walking in, though: trim-only work or a handful of deck boards tends to sit cheap no matter what. The moment a sill plate, rim joist or post base gets involved, shoring and a county inspection come along with it, and the price follows. More than anything else, what moves the number is simply how many seasons a leak has already gotten away with running unnoticed, which happens easily on a building nobody checks on daily.
Material almost never drives the bill, which catches most people off guard. What actually costs money is reaching the damage and putting everything back the way it was: staging, pulling siding clear of the problem area, bracing a load while a bad piece comes out, then closing it up so nothing shows. A building set back on a long driveway, or tucked behind another structure on the property, simply takes longer to reach with tools and material than one sitting right off the road.
Ranked by where your money actually lands: the crew’s time comes first, then whatever seals the repair against weather for good, flashing, wrap, siding, a coat of primer and paint, then the replacement wood itself, and last, a permit fee through Clark County Building Safety on anything structural. Every item that has to come down and go back up, a light, a downspout, a stretch of railing, gets its own line, so you can see plainly what paid for wood and what paid for getting to it.

Exterior work like this barely touches daily life inside the house, which holds true everywhere we do it, but on a lot with this much open ground around it, there is not even a shared wall or a close neighbor’s yard to work around. Here is roughly how the days tend to break down.
We walk the property with you first, flag what is actually coming off, whether that is the house or a shed further back on the lot, and settle where the dumpster, the staging and the lumber pile will sit. On a bigger parcel that usually means more room to work with than a tight in-town lot, though we still confirm where the septic drain field actually runs before anything heavy gets parked or driven across the yard. Anything breakable near that wall gets moved clear first, whether that is you or us doing the moving.
Siding and trim come off through the morning, and the wall is open by early afternoon. Out here the noise rarely bothers anyone beyond the household itself, since the nearest neighbor is often a field or two away rather than across a shared fence line. That open stretch of wall is still the only thing that actually settles whether the possible-extent line on your estimate turns into real work or gets crossed off.
A worse-than-expected finding does not wait for a follow-up call days later. It gets a text or a call from us that afternoon, pictures attached, and the saw stays quiet until you have actually said go. Whatever building the surprise turned up on, the rule stays the same: nothing past what is already approved happens on its own.
New framing and fresh sheathing go in, and flashing plus house wrap follow before the crew leaves for the day, so no opening sits through a wet night, on the house or on an outbuilding either one. Working a lot this size usually means staging enough material on site to finish a section in one pass rather than making extra supply runs, which helps keep an opening from sitting any longer than it has to. If weather beats us to the finish anyway, the gap gets wrapped in plastic sheeting and taped at every seam until it clears.
Siding goes back on, then trim, then sealant and a first coat of primer. At this stage the wall already looks finished, though out here there is rarely a passerby to notice, since the nearest neighbor might be a field or two away rather than across a shared fence. The only one likely to see it fresh is whoever comes up your own driveway next.
Paint goes on last. Once the yard is cleared and swept, you and I go through the finished work together, checking it line by line against what the estimate promised, whether that covers one wall or pieces on two different buildings. Everything that came out of the walls, every cutoff, and the dumpster itself ride off with the crew before we call it done.
A simple test beats guessing from across the yard: push a thumbnail or a key corner into the spot that worries you. Solid wood barely takes a mark. Wood that is actually failing gives way with almost no pressure and often smells faintly musty as it crumbles, whether that board sits on the house or on a shed nobody has paid attention to in years. Whichever test you run, a photo and a short note get you a real answer, usually that same day if it reaches us before we close up shop.
If the one board you are pointing at really is the full extent of it, that is exactly what we will say, no padding the job to make it bigger. But rot does not stop just because new siding gets nailed over it, and a shed or barn built by a previous owner with no paperwork on what is actually behind the wall can hide a longer run than the house does, where the original construction is at least generally known. Before we quote anything past the spot you flagged, we open it up far enough to find where the soft wood genuinely ends.
It happens often enough, on a shed as much as on a house, that we plan for it instead of springing it on you partway through. The estimate separates what we can confirm from outside from whatever the open wall might still reveal, and that second part sits on its own line with its own number. Nothing on it moves forward until you have seen the photos and told us to proceed.
That depends on your specific policy and on what actually caused the water intrusion, which makes it a question for your insurer, not for us. One thing worth asking your agent about separately: many policies cover a detached structure, a shed, a garage, a barn, under its own “other structures” limit, distinct from whatever covers the house itself, so a claim involving an outbuilding can work differently than one involving your home. What we can do either way is document everything with photos and notes as we find it, so you are walking into that conversation with evidence instead of a guess.
We do, any time the work actually touches something structural, a rim joist, a sill plate, a post base or a deck ledger, on the house or on an outbuilding. Since Brush Prairie is unincorporated, there is no city hall to file with. Everything goes through Clark County Building Safety and the CC LMS portal, and we handle that filing and meet the inspector ourselves. That holds even on a shed or barn nobody ever pulled a permit for when it first went up. Straightforward cosmetic trim or siding work usually needs no permit at all.
Timeline comes down to scope, not square footage. Stick to trim or a run of siding and you are looking at a single day, occasionally bleeding into a second. Once a sill plate, rim joist or post base needs replacing, plan on more time, since shoring, the county sign-off, and getting the opening weathertight again have to happen in sequence, and finish coats need genuinely dry air to cure. We write an actual day range into every estimate rather than a guess. Being home is not required for most of it, but stay reachable the day we open the wall. That is when any call about hidden damage actually lands with you.
Usually, though it depends on what is actually on each building, and those two answers are not always the same. A house still carrying its original cedar trim gets cedar back, milled to the same profile. A shed or barn an owner built or re-sided on their own over the years might be sided in something else entirely, plain pine, salvaged lumber, even plywood, and the honest first step is confirming what is actually there rather than assuming it matches the house. Where an exact profile is no longer sold, we build it up from stock until the reveal lines up with what is already on that specific wall.
Not the repair itself, since the work stays at the wall or the deck and does not touch either system directly. Where it matters is logistics: before we stage equipment, lumber or a dumpster anywhere on the property, we ask where your well head and septic drain field actually sit, so nothing heavy gets parked or driven across either one. On a lot with more open ground than a typical in-town yard, that is usually simple to work around, but we confirm it before anything shows up rather than guessing.
Evergreen’s shop sits at 505 SE 184th Avenue in east Vancouver, a straight run north on SR-503 that gets us to Brush Prairie well short of where that highway reaches the incorporated city further up the road. We cover the whole area, from the five-acre and larger parcels strung along Route 503 itself to the quieter acreage toward Meadow Glade and Hockinson, and we work Orchards and the rest of unincorporated Clark County right alongside it. The Hockinson School District has kept its headquarters here since 1870, and Brush Prairie Cemetery, dating to an 1865 land donation, is one of the older burial grounds in this part of the county, though you would not necessarily guess either fact driving down Route 503 today. Structural permits on this ground go through Clark County Building Safety and the CC LMS portal. Washington licensed, WA Lic. #EVERGRS757MC.

David's work was terrific. Repaired a rotted out structural framing issue in a bathroom and replaced (and resized!) a window in the same space. He initially quoted a two day job but was able to finish in a single day. Dedicated! Will be using him again.

We talked to 4 different contractors and only David, of Evergreen, took the time to climb up to our roof to check out the job. The others gave us bids based upon a photo. Evergreen was not the cheapest but the extent of the work they did was worth every penny.

Evergreen crew installed three skylights for us. Once we opened the ceiling there was more to do than expected and they handled it without drama. Clean work, fair price, and they cleaned up after themselves.
