Repair the Siding or Replace It? What Each Costs in Vancouver, WA

No, and anyone quoting you a percentage made it up. A Pacific Northwest contractor's repair guide states it directly: there is no universal percentage or simple rule that determines the answer, because the decision depends on the condition of the particular home. The things that actually move it are how much siding is damaged, whether the problem is localized, whether concealed moisture damage exists, the condition of the siding around it, whether matching material is still available, whether installation defects are widespread, whether repeated repairs have already been done, and whether the wall assembly behind it needs broader reconstruction.

That list has an order of operations buried in it. Identify the problem first, then pick the scope. Doing it the other way round leads to one of two bad outcomes: repairing the same symptom over and over, or replacing large areas of siding that were still doing their job.

When the damage is confined to one area and the siding around it is still serviceable. The regional guide's test is five-part: damage confined to a specific area, surrounding siding still serviceable, the cause correctable locally, replacement material that can be integrated effectively, and concealed damage that does not extend significantly past the affected area.

Age of the house is the quickest proxy for that. A fifteen-year-old house rarely needs replacing: on newer Ridgefield subdivisions, where the median home was built in 2012, the find is usually an installation defect worth a few hundred to correct. Camas and Battle Ground are older than that, with median years built of 2001 and 2003, so they sit closer to the point where the question is genuinely open. Cedar is its own case. In Clark County cedar is usually a repair-and-match situation rather than a full re-side, and it carries a maintenance cycle the other materials don't. What a repair runs by part of the house is on the wood rot and trim page.

When the siding has reached the end of its practical service life, or when several areas are failing at once. The same guide lists seven signals: deterioration that is widespread, multiple areas failing, siding at the end of its service life, repair material that can't be matched or integrated, installation defects across the wall system, an owner who wants a different exterior, and concealed damage that needs broad access to the wall anyway.

Service life is the one you can look up rather than argue about. Fiber cement has a 30- to 50-year life with proper installation in Pacific Northwest conditions, and vinyl 20 to 30. A wall at the top of its bracket will keep producing repairs whatever you do to it this spring. Two more things point the same way. Painting over rot seals moisture in, so the wall looks fine for two years and then the repair triples. And damaged siding near a window does not prove the window is leaking, so replacing one board may not solve a problem where water is entering higher up the wall. If the second repair in three years is on the same elevation, you are paying maintenance on a wall that needs replacing.

Published ranges, smallest scope to largest, from local price pages checked for this site:

• A trim board, a corner board or a few courses, no sheathing damage: $350 to $1,200
• One area of siding with rot, including replacement: $1,000 to $5,000
• A major structural rot project: $8,000 to $25,000 plus
• A full vinyl re-side of a typical home: $8,000 to $18,000
• A full fiber cement re-side of a typical home: $16,000 to $32,000

One Camas and Vancouver installer prices its siding at about $900 per square of 100 square feet installed, plus roughly $300 per square to tear off and haul the old material, and other local pages put tear-off and dump fees at $1 to $3 per square foot. Note the gap in the middle of that list: nothing published sits between a $5,000 repair and a $6,000 re-side of a 2,000 sq ft home, so the decision is rarely a near-tie on price.

One thing surprises people. Material is the smallest lever of the five on a re-side, because the labor to remove old siding, correct what is behind it and detail the new cladding properly is similar whichever product goes back on. Switching from Hardie to vinyl saves less than most people expect. The cost guide ranks every driver, and the price updates log records each change to these ranges.

Where the water comes from, and how far the damage runs past what you can see. The most important question on a siding repair is not whether to replace a board or a wall, it is why the siding failed in the first place. Until that is answered, a quote for either scope is a guess.

So ask for four things in writing: the cause named specifically, how far past the visible damage the contractor intends to open the wall, the rate for sheathing and rot repair if more turns up, and whether the trim, corner boards and fascia are replaced or reused. That last one quietly separates bids. A quote that re-sides the field and reuses old cedar trim that is soft at the bottom edge means new siding detailed into rotting wood. Walls on pre-1940 homes often have no drainage plane at all behind the cladding, and sometimes no sheathing, which is why age changes the answer more than appearance does. The siding contractor hiring guide has the full bid checklist.

If the windows are near the end of their life, yes, and it tips the decision toward replacement. The moment the siding is off, the window flanges and the weather barrier are exposed and accessible, so doing window replacement during the re-side is meaningfully cheaper than doing it as two separate projects, because the opening only gets opened once. Whether windows are re-flashed and wrapped, or the siding is simply cut to the existing trim, is the highest-consequence line item on the estimate and the easiest one to leave off.

House shape matters here too: every bump-out, gable return, dormer and corner is a cut, a corner detail and a place water has to be kept out of, so a simple box costs less per square foot than a Craftsman with three gables and a wrapped porch. Keeping existing window openings also keeps the paperwork to the siding in most of the nearby cities, which is set out city by city in siding permits across Clark County. How we price siding explains why none of these numbers is a quote.
