Know the Signs

When to replace siding — and when to repair.

Siding failure in the Portland metro follows a predictable pattern. Oregon's combination of persistent winter rain, morning fog, and limited winter sun creates conditions that are harder on exterior cladding than most homeowners realize — particularly on north and east-facing walls that get little direct sun to dry out.

The question we get most at estimates is whether to repair or replace. The honest answer depends on the material, the extent of failure, and what we find when we look behind the damaged sections. Fiber cement with a few cracked boards is a repair. Hardboard siding that's bubbling at every seam is a replacement. Wood siding with 10 coats of paint that's losing adhesion everywhere is a replacement. We give you a clear recommendation at the estimate and price both options when both are genuinely viable.

One thing we always do on siding estimates: we check north and east-facing walls carefully for moisture damage behind the siding that isn't visible from the street. Hidden rot and mold behind panels doesn't show up until the siding comes off — and it's better to find it at the estimate than mid-project.

Bubbling, peeling, or flaking paint
Often indicates moisture behind the panel — not just a paint problem
!
Seams that are cracking or separating
Hardboard and engineered wood siding fail at seams first as moisture penetrates
!
Soft spots when you press on a panel
Soft panels mean the substrate or sheathing behind is already deteriorating
!
Visible warping, cupping, or swelling
Wood-based products that have absorbed moisture beyond their tolerance
!
Mold or mildew staining on exterior walls
Especially on north and east faces — indicates persistent moisture that isn't drying out
!
Higher-than-expected heating or cooling bills
Failing siding with gaps allows air infiltration that significantly reduces insulation performance

Siding Materials

The right material for Oregon's climate.

Each siding material performs differently in Oregon's wet seasons. Here's an honest picture of what we install and why we recommend what we do.

Our top recommendation

Fiber Cement

James Hardie HardiePlank & HardiePanel

The most moisture-resistant siding available for Oregon's climate. James Hardie fiber cement is engineered specifically for high-moisture, freeze-thaw environments — it won't rot, warp, or support mold growth. Comes factory-primed and available in pre-painted ColorPlus options. Carries a 30-year warranty when installed to manufacturer specs. Our recommendation for the vast majority of Portland metro homes.

Lap siding Vertical panels Shingle style 30-yr warranty

Vinyl Siding

CertainTeed, Alside, Mastic

Zero-paint-maintenance siding with good moisture resistance and a lower upfront cost than fiber cement. Color is integral to the material so it never needs repainting — though it can fade over time with UV exposure. Performs best in moderate conditions. Can become brittle in extreme cold and may crack on hard impact. A strong option for budget-conscious projects where fiber cement is outside range.

Lap profiles Dutch lap Insulated Low maintenance

Wood Siding

Cedar, pine, T1-11, bevel

The traditional choice with genuine character — appropriate for period-correct restoration on older homes where fiber cement would compromise the historic profile. Cedar is naturally rot-resistant and holds paint well when properly installed with adequate air gaps. Requires painting or staining every 5–7 years. We recommend wood only where it's the right choice architecturally; for most Oregon homes it's not the practical first choice given the maintenance burden.

Our Process

How a siding project works with OJB.

From first call to finished walls — here's exactly what to expect.

01

Free on-site estimate

We walk the full perimeter, check north and east-facing walls for moisture indicators, probe any soft or damaged sections, and assess what's behind the problem areas. You get a written price that accounts for what we actually find — not a ballpark based on square footage alone.

02

Written price — locked

Full itemized estimate: siding removal, sheathing repair if needed, house wrap, siding material, trim, and finish. Hidden moisture remediation is scoped in where we find it at the estimate. The number doesn't change once you approve it.

03

Removal & prep

Old siding comes off, sheathing is inspected and repaired where damaged, new house wrap goes on with properly lapped seams, and window and door openings are flashed to manufacturer specs. The substrate is right before new siding ever touches it.

04

Install & finish

Siding installed to manufacturer specs and local code. Corner trim, window trim, and soffit transitions completed. Factory-primed fiber cement is paint-ready for your painter or we can coordinate a finish coat. Full walk-through with you before we leave.

Why OJB for Siding

Built on trust. Weatherproofed for Oregon.

01

We check what's behind the siding before quoting

The most expensive surprise in a siding project is finding rot, mold, or failed sheathing after the old siding is already off. We probe north and east-facing walls at every estimate, check for soft spots and moisture staining, and scope any substrate issues into the written price upfront. No mid-project additions when the walls open up.

Pre-install moisture assessment
02

Drainage plane and flashing done right — every time

The most common cause of premature siding failure is improper installation — house wrap lapped wrong, window flashing skipped, no air gap behind panels. We install to manufacturer specs and Oregon code on every job: properly lapped house wrap, pan flashing at all window sills, and drainage gaps that let walls breathe. We don't skip these steps to go faster.

Correct installation, start to finish
03

James Hardie certified installation

We install James Hardie fiber cement products to their published installation guidelines — the specific requirements for fastener type and spacing, clearances from grade, flashing at horizontal joints, and caulk product selection that govern whether the 30-year warranty stays valid. Cutting corners on a Hardie install doesn't just look bad — it voids the warranty.

FAQ

Common siding questions.

James Hardie fiber cement is our consistent recommendation for the Portland metro. It's specifically engineered for high-moisture, freeze-thaw environments — the exact conditions Oregon delivers every winter. It won't rot, warp, or support mold growth, carries a 30-year warranty when properly installed, and is available in profiles that match virtually any architectural style. Vinyl is a sound second choice where budget is a primary driver. Wood is appropriate for period-correct restoration where architectural authenticity matters more than long-term maintenance cost.

Repair makes sense when damage is isolated — a few cracked fiber cement boards, a small section of wood rot around a window, or a single damaged panel. Replacement makes sense when failure is widespread (bubbling or cracking at every seam), when the material has reached the end of its useful life (hardboard siding from the 1980s–90s in most cases), or when there's moisture damage behind the panels that requires opening the whole wall anyway. We'll assess honestly at the estimate and price both options when both are genuinely viable.

Signs of hidden moisture behind siding include: paint that bubbles or peels repeatedly even after repainting, a soft or spongy feeling when you press on a panel, interior walls that feel damp near exterior surfaces, and persistent mold or mildew staining on north or east-facing walls. At the estimate we probe suspect areas and check for moisture indicators before quoting — it's far better to find it at the estimate than mid-project when the walls are open.

James Hardie fiber cement carries a 30-year limited warranty when installed to their published specifications. In practice, properly installed and painted fiber cement in the Portland metro typically lasts 40+ years with minimal maintenance beyond repainting every 10–15 years. The warranty requires proper installation including correct fastener type and spacing, minimum clearances from grade, and specific flashing at horizontal joints — all of which we follow on every install.

In most Portland metro jurisdictions, like-for-like siding replacement does not require a permit. However, if the project involves changes to the building envelope, modifications to window or door openings, or structural sheathing replacement, a permit may be required. We determine permit requirements at the estimate and handle any necessary applications as part of the project.

For partial replacements — a damaged section or one wall — we work to match the existing profile as closely as possible. James Hardie makes a wide range of lap widths and profiles that match most common existing siding styles. For very old or unusual profiles, we'll discuss options at the estimate including whether a full-house replacement in a matching modern profile makes more sense than trying to blend old and new.

Fiber cement comes factory-primed and requires a finish coat of exterior paint. James Hardie also offers ColorPlus pre-painted siding where the color is baked on at the factory — this option comes with a 15-year fade and chip warranty and eliminates the painting step entirely. Vinyl siding never needs painting — the color is integral to the material. We'll discuss paint options at the estimate and can recommend painters we've worked with if needed.

Yes. Our Oregon CCB license (#255649) covers all construction work including siding installation throughout Oregon. We also hold a Washington contractor license (#OREGOJB755C8). We carry full general liability and workers' compensation insurance on every job and can provide proof of coverage before any work begins.
