Laurelhurst Primed Cedarmill HardiePlank Siding With Cedar Shingle Accent

This Laurelhurst, Seattle, WA project was built as a complete exterior case study, not just another list of siding materials. KV Construction looked at the house as a full wall system: what had to come off, what had to be checked behind the old siding, how water would be managed around windows and doors, and how the finished exterior should feel in its local setting.

Laurelhurst sits close to Lake Washington, so siding choices need to handle wet winters while still fitting the quieter, established look of the neighborhood. The cedar shingle accent on the pop-out kept the project from feeling flat, while the Hardie lap siding created a stronger long-term envelope.

The core installation centered on 6 1/4-inch primed Hardie lap Cedarmill siding with a 5-inch reveal. The combination of Cedarmill HardiePlank, carefully cut cedar shingles, and Kingspan panels gave the home both texture and a better moisture-conscious wall assembly. The work also included cedar shingle accent, Kingspan panel installation, full HardieWrap and flashing reset, which made the project more layered than a standard siding replacement and gave the final result a stronger sense of place.

Why This Exterior Needed More Than New Boards

The project started with removal and prep because the parts behind the siding determine how well the finished exterior performs. KV Construction does not position this kind of work as a small patch job; the goal is to reset the weather-facing wall system so the new siding has the right foundation.

Weather Barrier, Flashing, and Rain Control

Pacific Northwest siding work has to respect water. On this project, the weather barrier was HardieWrap paper with 1 1/2-inch Hardie seam tape. Flashing details included 4-inch HardieFlash tape, 26GA window head flashing, primed Z metal flashing, and primed W inside corners. HardieWrap, seam tape, and detailed flashing created the water-management layer behind the siding, which is the part homeowners rarely see but rely on every winter. QUAD MAX sealant was used at key transitions so trim, blocks, windows, doors, and siding could work together instead of becoming separate weak points.

Material Choices That Fit the Home

The main siding choice was 6 1/4-inch primed Hardie lap Cedarmill siding with a 5-inch reveal. KV Construction paired that with Prime rustic Hardie 5/4×4 outside corners, window trim, and door trim. This is where a case study becomes more than a materials list: the profile, reveal, texture, trim depth, and finish all influence how the home reads from the street and how well the edges are protected.

Details That Made This Project More Complete

Several project details shaped the final result: 3/8-inch Kingspan panels; Old siding demolition and full disposal; circular saw cut prime cedar shingles installed on the pop-out. These items matter because siding replacement often exposes the places where older exteriors were weakest: soffits, corners, window transitions, door openings, insulation gaps, or paint systems that no longer protect the home well.

Outcome and Homeowner Value

The finished project gives the home a more complete exterior system, with the visible siding, trim, soffit, window/door details, and hidden water-management layers all tied into one scope. The result is the kind of project KV Construction wants to be known for: practical, well-organized, and built around a full siding replacement mindset suited to Seattle-area and Pacific Northwest weather.
