Siding Replacement Cost in Portland: Sourced Ranges
Published price ranges for siding work in and around Portland, each with its source and the date it was checked, and the parts of a quote those ranges leave out.
Siding replacement cost in Portland, Oregon depends mostly on how much wall there is, which material goes on, and what turns up once the old siding comes off. The table on this page gathers published figures, each labeled with its source, whether it is a Portland, regional or national number, and the date it was last checked. Treat them as reference points for reading a quote, not as a quote.
Portland Siding Pros does not price siding work. When you send a request, an independent local siding contractor looks at the house and gives you their own quote.
How to read the ranges
- Per-square-foot figures are installed prices for the siding material, per square foot of wall. Multiply by your wall area (not your floor area) for a rough scale, then add the lines they leave out: tear-off, sheathing repair, trim and paint.
- Per-job regional averages come from the Remodeling 2025 Cost vs. Value Report and describe one house size, 1,250 square feet of siding including trim. Portland is not reported separately; the figures average the report’s Pacific region markets.
- Repair figures for Portland describe a typical repair visit, not a job where rot has reached the sheathing.
What do siding materials cost to install?
The table below compares fiber cement, vinyl, cedar, engineered wood and T1-11. Fiber cement and cedar sit higher per square foot than vinyl and T1-11; engineered wood sits in between. Fiber cement’s price buys a board that does not rot; cedar’s buys real wood that can be repaired board by board; vinyl’s lower price comes with sensitivity to heat and installation.
Repair or replacement: which budget are you in?
A siding repair on one wall usually lands within the Portland repair range in the table. Full replacement is a different order of cost, which is why it is worth being sure the siding has actually failed before pricing it. The common reasons it has are swollen hardboard, failing T1-11 and rot from water behind the siding.
Getting comparable quotes
Quotes only compare when they cover the same scope. Ask each contractor to list:
- tear-off and disposal, and lead-safe work if the house predates 1978;
- a unit price for sheathing replacement;
- the house wrap, flashing and drainage gap they will install;
- trim, soffit and fascia scope and material;
- paint or finish, and how many coats;
- who handles any permit or historic review.
Oregon requires a written contract for residential work over two thousand dollars, showing the contractor’s CCB license number.

Prices on this page are general ranges gathered from published sources, not a quote. What a job actually costs depends on the specifics of the job and who does the work. Only a quote from a qualified contractor who has seen the job is a real price. Last reviewed September 27, 2026.
What goes into the price
Wall area, not floor area
Siding is priced by the square foot or by the square (100 square feet) of wall, minus large openings. A two-storey house has far more wall per square foot of floor than a ranch, which is why price-per-house-size figures mislead.
Tear-off and disposal
Removing and hauling away the old siding is a line of its own, and it costs more when the old paint may contain lead or the siding is fastened over a second layer.
Sheathing and framing repair
The biggest unknown in any Portland re-side. Nobody can see the sheathing until the siding is off, so good quotes price it per sheet or per hour rather than guessing a total.
House wrap, flashing and drainage gap
A continuous water-resistive barrier, flashed windows and doors, kickout flashings and, where required, furring or a drainage mat. These are the parts that keep water out of the wall, and the easiest to leave out of a low bid.
Trim, soffits and fascia
Window and corner trim, frieze boards, soffits and fascia can be kept, replaced in wood, or replaced in fiber cement or PVC. Each choice changes the price.
Paint or finish
Primed fiber cement and new wood need painting after install; prefinished boards and vinyl do not. Ask whether the quote includes paint, how many coats, and who picks the color.

What changes the price
Stories and access
Second- and third-storey walls need scaffolding or lifts. Steep lots, tight side yards and landscaping against the house slow the work.
Rot found behind the siding
Every sheet of sheathing replaced adds material and labor. Houses with long-running leaks at windows and roof corners find more.
A pre-1978 house
Lead-safe setup, containment and cleanup add time and cost when 20 square feet or more of old paint is disturbed, which a tear-off always does.
Architectural detail
Gables, bays, dormers and many windows mean more cuts, more trim and more flashing per square foot than a plain rectangle.
Material grade and profile
Prefinished over primed fiber cement, clear over knotty cedar, shingles over lap boards and insulated over standard vinyl all move a job up the range.
Review and permits
Historic resource review in Portland's historic and conservation districts, or a permit for a fire-rated wall near a property line, adds lead time and sometimes design requirements.
Common questions
What does a full re-side cost on a Portland house?
It depends on wall area, material and what is found behind the old siding. As a reference point, the table on this page gives the Remodeling 2025 Cost vs. Value Report's Pacific region averages for replacing 1,250 square feet of siding with trim in fiber cement and in vinyl. Those are regional averages, not Portland quotes; the contractor's written quote is the only price that applies to your house.
Is fiber cement more expensive than vinyl?
In the sources on this page, yes. Installed fiber cement runs higher per square foot than vinyl, and in the 2025 Cost vs. Value regional averages the fiber cement re-side comes in above the vinyl one for the same house size.
Why are there no Portland totals for every material?
Few published sources report Portland-specific siding prices with a clear date and method. Some Portland figures on cost websites are sized by the floor area of the house rather than the wall area, which makes them unreliable for siding. This page uses Portland figures where a dated source exists and national or regional ranges otherwise, and labels each one.
Are these the prices a contractor will charge me?
No. Portland Siding Pros does not set or quote prices. These ranges are published reference points to help you read a quote; the contractor sets the price after seeing the house.
