- House wrap installation for moisture protection
- Installation of siding system (Hardie, Cedar, etc.)
- Vertical corner molding (VCM), window trim, and door trim
- Caulking, sealing, and weatherproofing
- Final walkthrough and approval
Siding Materials We Install
We install siding systems built for durability, performance, and long-term protection in our unique climate:
- James Hardie fiber cement siding: The gold standard for moisture resistance.
- Cedar lap cladding: Natural beauty with high-end craftsmanship.
- Cedar shingle siding: Architectural detail and custom textures.
- T1-11 siding: Professional demo and full replacement systems.
Material Performance: Hardie vs Cedar
James Hardie Fiber Cement
Dense, stable composite material that allows paint to adhere spectacularly well. Paint molecules form a tight-knit bond with the substrate, lasting significantly longer than wood.
Cedar Lap & Shingle
Offers unmatched natural aesthetics but requires more upkeep. Wood expands and contracts, which can eventually lead to paint failure if moisture permeates the coating.
The Tannin Bleed Issue
Cedar siding also has another issue known as tannin bleed—naturally occurring compounds that can migrate to the surface and cause brown or yellow staining. Preventing this requires high-quality stain-blocking primers and specialized application methods that ACGI has mastered over four generations.
T1-11 Siding: Short-Term Savings vs Long-Term Risk
T1-11 siding covers a large amount of square footage with a single sheet, which can save homeowners money upfront. However, those short-term savings often lead to long-term problems—especially in the Pacific Northwest.
When rain hits the siding, the bottom horizontal edge tends to retain water. Combined with wind-driven moisture and repeated wet/dry cycles, the water begins to wick upward into the panel, damaging the backside where it’s not visible. This often leads to hidden dry rot and expensive repairs. ACGI strongly recommends upgrading to James Hardie for superior protection.
Make the Right Siding Decision the First Time
Do it once. Do it right. ACGI recommends fiber cement siding systems like James Hardie for most Portland homeowners who want to preserve their property value.
