Hillsboro’s Dependable Deck Installer — Owner on Every Job, Properly Flashed & Built Tough
The structural rot VResh finds most often on Hillsboro homes is not at the deck surface — it is at the ledger board, where an improperly flashed deck attachment has been directing Tualatin Valley rain straight into the rim joist and floor framing of the house for 25+ years.
This damage is invisible from the exterior until it is significant and expensive. VResh builds every deck with a properly flashed ledger connection — a through-wall flashing assembly that prevents water from reaching the framing — and when we remove an old improperly flashed ledger, we repair the rot we find before the new ledger goes on.

Why Hillsboro Decks Need Attention Now
Hillsboro's 1990s–2000s housing expansion produced a large number of decks built to older construction standards — particularly at the ledger connection, where proper through-wall flashing was often omitted. These decks are now 25–35 years old and entering their natural failure cycle.
The Hillsboro Deck Ledger Problem
Deck ledger flashing requirements were not consistently enforced during the 1990s in Washington County. Many decks were attached directly through siding to the rim joist without proper flashing.
Water enters at fastener points, saturates the rim joist, and spreads into surrounding framing. After decades of exposure to Hillsboro’s wet climate, structural damage at the ledger connection is often severe.
First-Generation Composite Decking Failure
Many Hillsboro homes built in the 1990s–2000s used early composite decking products that were not capped and had limited moisture resistance.
These materials commonly show fading, staining, swelling, and breakdown after years of exposure. Replacement provides an opportunity to rebuild the deck with modern materials and proper moisture protection.
Repair vs. Replacement — What Makes Sense
Not every deck needs full replacement. Surface board wear with solid framing can be repaired. However, structural damage at the ledger, posts, or framing requires deeper work.
VResh evaluates each deck honestly — recommending repair when appropriate and full replacement when structural integrity is compromised.
What VResh Actually Does on a Hillsboro Deck Project
A deck built correctly starts with a properly flashed ledger and ends with a permit inspection. Here is what that looks like on a Hillsboro home.
Site Assessment and Ledger Evaluation
Assess the existing ledger condition, rim joist, and surrounding siding at the attachment point. If the ledger is being removed, the full structural condition behind it is inspected before any new work is specified.
What VResh Finds on Hillsboro Decks
- Rim joist rot — the most common issue after decades of moisture intrusion
- No flashing at ledger connection — water entering at every fastener point
- Siding damage near ledger — swelling, cracking, or deterioration
- Incorrect hardware — non-ACQ-rated fasteners corroding over time
Ledger Installation with Through-Wall Flashing
Install the new ledger using a full through-wall flashing system integrated into the siding and weather barrier. Structural bolts secure the ledger, ensuring long-term durability and moisture protection.
Critical Steps Most Contractors Skip
- Proper metal flashing behind siding — not just surface tape
- Fastener standoffs or flashing washers to prevent water pooling
- Integration with WRB for correct drainage path
Permit, Footings, and Structural Framing
Permits are secured before construction. Footings are installed to required depth, and framing is built using proper structural design to support load and ensure long-term performance.
- Concrete footings to code depth
- Posts, beams, and joists properly sized and installed
- Joist hangers used instead of toe-nailing
- Blocking added for structural stability
Decking, Railings, and Final Inspection
Install decking, railings, stairs, and all finishing components to meet code requirements. Final inspection is completed before project closeout.
- Composite or wood decking installed correctly
- Code-compliant railing height and spacing
- Proper stair construction and handrails
- Final inspection and workmanship warranty
Deck Materials for Hillsboro's Climate
Hillsboro's 38-inch annual rainfall and sustained wet season require careful material and fastener selection:
Pressure-Treated Lumber — Best Value for Most Hillsboro Decks
Current ACQ or CA-B pressure-treated lumber is rated for direct ground contact and above-grade applications. Cost-effective and structurally sound. Fasteners must be hot-dip galvanized, stainless, or specifically ACQ-rated — standard zinc-coated hardware corrodes rapidly in contact with ACQ pressure treatment.
Composite Decking (Trex, TimberTech, Fiberon) — Lowest Lifetime Maintenance
Modern capped composite decking does not require sealing, does not splinter, and resists staining and fading significantly better than the first-generation composites installed on 1990s-2000s Hillsboro homes. Higher upfront cost than pressure-treated but lower lifetime maintenance. The right choice for Intel and Nike homeowners prioritizing a low-maintenance outdoor space.
Cedar — For Hillsboro Homeowners Who Prioritize Appearance
Western red cedar provides visual character. Requires sealing or staining every 2–3 years in Hillsboro's wet climate. Cedar's natural rot resistance does not extend to structural framing — posts and beams should still be pressure-treated near grade or subject to water contact.
