Lake Stevens Primed Cedarmill James Hardie Siding With Localized OSB Repair, Boral Trim & Two-Color SuperPaint

This Lake Stevens, WA project was built as a complete exterior case study, not just another list of siding materials. KV Construction approached the work as one exterior system, coordinating the main cladding with the documented preparation, weather protection, transitions, and finish details.

In Lake Stevens, localized deterioration in older panel siding is common enough that repairing the documented weak areas before the finished exterior goes on can make a major difference.

The core installation centered on 8 1/4-inch primed Cedarmill James Hardie lap siding. Several project-specific details shaped the scope: pressure washing, caulking repair, two-color Sherwin-Williams SuperPaint on the house, and two-color shed painting completed the finish scope. Together, those choices gave the project a clearer architectural identity while keeping the scope grounded in the actual materials and processes used on site.

Localized Substrate Repair Before New Cedarmill Hardie

The project started with the preparation that mattered for this specific exterior: old window trim, corners, and moulding removed; rotten spots in LP panels replaced with OSB plywood. That work gave the new siding system the right foundation instead of treating the project as a surface-only update.

Weather Barrier, Flashing, and Rain Control

Pacific Northwest exterior work has to respect water. On this project, the documented supporting system included HardieWrap, 4-inch HardieWrap Pro-Flashing, and QUAD MAX. Those layers and transition details help the siding, openings, corners, penetrations, and adjoining surfaces work together through the region’s long wet season.

Material Choices That Fit the Project

The main exterior choice was 8 1/4-inch primed Cedarmill James Hardie lap siding. KV Construction paired that with Boral 5/4×4 outside-corner and window trim. The profile, spacing, texture, trim depth, and color or finish all influence how the building reads from the street, while the supporting details protect the edges where materials meet.

Details That Made This Project More Complete

Several project details made this scope more complete: Pressure washing, caulking repair, two-color Sherwin-Williams SuperPaint on the house, and two-color shed painting completed the finish scope. These items are important because siding projects often become most complex at soffits, openings, rooflines, lower-wall transitions, gutters, or places where two materials and profiles meet.

Outcome and Property Owner Value

The finished scope gives the property a more coordinated exterior, with the visible siding and the supporting details tied into one project. It is the kind of work KV Construction wants to be known for: practical, well-organized, and built around durable siding systems suited to Pacific Northwest weather.
