Why Siding Fails in Portland — and What We Do About It
Portland gets more than 150 days of rain a year, and most of it arrives sideways. Siding here doesn't usually fail because the boards wear out — it fails because water finds its way behind them at a window, a corner or a hose bib, and nobody sees it for years.
By the time a homeowner calls us, the siding looks tired but the real damage is in the sheathing underneath. North-facing walls grow moss. Bottom courses soften. Trim around windows goes spongy.
That's why we don't just hang new boards. Every job includes a full inspection of what's behind the old siding, replacement of any rotted sheathing, a proper weather-resistive barrier, and flashing at every penetration. It's the part you never see and the only part that decides how long the job lasts. On full replacements we install a rainscreen — a vented gap between the siding and the wall that lets water drain and the assembly dry out instead of holding moisture against the sheathing. In a climate with 150 rain days a year, that gap is much of the difference between siding that lasts fifteen years and siding that lasts forty.
Vinyl & Engineered Wood Siding
Natural Wood & Cedar Siding
Classic Pacific Northwest beauty for homeowners who appreciate the character of real wood and are willing to maintain it. We also handle repair, refinishing and tear-off when replacing old siding. Cedar needs refinishing every five to eight years in this climate; if you’d rather not sign up for that, we can walk you through exterior painting options or a lower-maintenance material instead.
- Vinyl (1,500 sq ft): $6,000–$12,000
- Engineered wood: $9,000–$16,500
- Fiber cement (Hardie): $12,000–$21,000
- Cedar: $12,000–$24,000
Siding Repair and Rot Repair
Not every house needs full replacement. If the siding is structurally sound and the damage is contained, repair is usually the better spend.
Rot rarely stops at the siding. We check the soffit, fascia and trim at the same time, because water that got behind one has usually got behind the others, and repairing the siding alone just hides it for a season.
We handle board replacement, rot repair at the sheathing and framing, trim and fascia replacement, re-flashing around windows and doors, and caulking and sealing before the wet season. If the roofline is involved, we handle roofing and gutters too, so you’re not coordinating two contractors on one wall.
Where we’ll tell you to replace instead: widespread rot, siding that’s been painted over several times and is cupping or splitting, or any wall where the moisture barrier behind it has failed. Patching over those problems costs more in the end. We’ll tell you which one you’re looking at before you spend anything.
What Hiring Us Actually Looks Like
Most homeowners get three bids and find they can’t compare them, because every contractor measures and describes the job differently. Here’s how ours works.
We come out and walk the house with you, measure every elevation, and check for soft spots and failed flashing. You get a written estimate that separates materials, labor, tear-off, disposal and permits — so you can hold it next to anyone else’s and see what’s actually different.
If you hire us, you get a start date, a finish date and one phone number for the whole job. Most houses take one to three weeks. We pull the permits and handle the inspections. Book your free estimate and we’ll come measure.
Siding Contractors Serving the Portland Metro
We install and repair siding across Portland and the surrounding cities — Beaverton, Gresham, Lake Oswego, Tigard, Hillsboro, Tualatin, Milwaukie, West Linn, Oregon City and Happy Valley.
Older Portland neighborhoods come with their own problems. Craftsman and bungalow homes in Sellwood, Woodstock and Montavilla often still have original cedar that’s forty years past its last real maintenance. Mid-century houses in Beaverton and Tigard tend to have T1-11 that’s delaminating at the bottom. We’ve worked on all of it — take a look at our recent projects.
