James Hardie Siding Installation in Portland, OR
HardiePlank Lap Siding. HardieShingle. HardiePanel. ColorPlus Factory Finish. Experienced Installer — Proper Technique, Not Just New Siding Over Old Problems.
James Hardie fiber cement siding is the most recommended exterior cladding product for Pacific Northwest homes — and VResh Construction has installed it on hundreds of Portland-area homes. We know the product line thoroughly: the correct clearances from grade and rooflines, the right fasteners, the specific caulk products the manufacturer requires, and the installation details that make the difference between a 30-year installation and one that fails before the warranty runs out.
What most Portland homeowners don't know: James Hardie siding can be incorrectly installed by contractors who don't follow the manufacturer's installation guide. The most common failures are too-low bottom course clearance (which leads to bottom-course rot within 5–10 years), missing or inadequate head flashing at windows, and use of standard caulk instead of the James Hardie-specified flexible caulk. We install James Hardie correctly, every time.
The James Hardie Product Line — Which is Right for Your Portland Home?
HardiePlank Lap Siding — Most Popular
The most widely installed James Hardie product. HardiePlank closely matches the appearance of traditional wood lap siding and is available in three profiles: Traditional (smooth), Cedarmill (wood grain texture), and Beaded (Craftsman style).
Available primed-only (field painted) or in ColorPlus factory finish (baked-on paint, 15-year fade warranty).
Best for: Ranch homes, Craftsman bungalows, and any Portland home where lap siding is the existing or desired profile.
Width options: 5.25", 6.25", 7.25", 8.25", 9.25", 12" — wider boards create a bolder, more contemporary appearance.
HardieShingle — Authentic Shingle Appearance
HardieShingle replicates the appearance of eastern white cedar shingle siding — extremely popular in Portland's Craftsman and Tudor-revival neighborhoods.
Available in staggered and straight-edge profiles. Used extensively on upper-story applications and gable ends where a traditional shingle look is desired.
Available primed or in ColorPlus finish.
Best for: Craftsman bungalows, Tudor revival homes, homes with existing cedar shingle detail to be maintained.
HardiePanel Vertical Siding — Contemporary Applications
HardiePanel is a vertical siding system — 4x8 or 4x10 panels installed vertically, typically with battens at joints. Creates a board-and-batten appearance.
Extremely popular in new construction and contemporary remodels in the Portland area.
Available in Smooth, Cedarmill, and Sierra 8 textures.
Best for: Contemporary designs, new construction, accessory dwelling units (ADUs), and garage re-cladding.
HardieTrim — Board Matching for a Unified System
HardieTrim boards and sheets are used for corner trim, window and door trim, frieze boards, and other trim applications. Using James Hardie trim with James Hardie siding creates a unified, all-fiber-cement exterior system with matching expansion rates.
Far more durable than wood trim, especially at vulnerable locations like window and door corners, where paint failure and rot typically start first.
ColorPlus Technology — Factory-Applied Finish
James Hardie's ColorPlus finish is a factory-applied, kiln-baked topcoat that significantly outperforms field-applied paint. It carries a 15-year fade, peel, and crack limited warranty — far longer than any field-applied exterior paint.
ColorPlus is available in over 700 colors and eliminates the need for a post-installation paint job.
Cost premium over primed siding: approximately 15–20% more than primed-only siding installed with a standard paint job. The 15-year finish warranty and longer repaint cycles often make ColorPlus the more economical choice over a 20–30 year period.
James Hardie's Warranty Depends on Correct Installation
The James Hardie 30-year limited product warranty is conditional on installation following the manufacturer's published installation guide. Specific installation requirements that contractors commonly miss and that void the warranty when not followed:
Minimum 6-inch clearance between the bottom course of siding and grade
Minimum 2-inch clearance above all roof surfaces at roof-to-wall intersections
Minimum 1-inch clearance above any flashing
Use of hot-dip galvanized or stainless steel nails — corrosion-resistant nails only
Use of a James Hardie-approved flexible caulk at required joints
Back-priming all field cuts with an approved exterior primer
Proper storage on-site, off-ground, protected from weather, and an acclimation period
We follow every one of these requirements on every James Hardie project. We also document the installation for homeowners who want a record of compliance for future warranty claims or home sale disclosure.
