Quality siding installation for Edmonds homes

This Edmonds exterior upgrade features smooth HardiePanels installed with clean, modern lines. We used ½-inch primed H-channels between vertical seams and primed Z-metal flashings along horizontal transitions to ensure a crisp architectural look and long-lasting moisture protection. The result is a sleek, contemporary finish that highlights the home’s mid-century design while delivering the durability of James Hardie fiber cement.

Certified waterproofing for long-term protection

Before installing the new siding, we completed full waterproofing using a complete James Hardie–approved system. The home was wrapped with HardieWrap weather barrier, all panel and lap seams were sealed with Hardie Seam Tape, and every window and door received proper flashing using HardieFlash for a secure, watertight installation. This layered protection ensures the exterior can withstand Edmonds’ consistent moisture, wind, and seasonal rain for years to come.

Entryway soffit upgrade with vented tongue-and-groove panels

The entryway received a clean architectural upgrade with rough 1×6 TK tongue-and-groove soffit panels, installed to add warmth, texture, and a refined finish to the front elevation. To maintain proper attic ventilation and long-term airflow performance, we added 2-inch continuous vents integrated seamlessly into the soffit. This combination provides both a beautiful natural wood look and dependable moisture control for Edmonds’ Northwest climate.

Upgraded exterior details with fiber cement and cedar trim

To complete the exterior, we installed Hardie Rustic 5/4×4 fiber cement corners for clean, durable edge transitions that hold up exceptionally well in Edmonds’ damp climate. Around the windows, we used finger-joint cedar 2×4 and 2×3 trim, finished with a cedar finger-joint slope seal to ensure proper water shedding and long-term stability. This combination of fiber cement and precision-milled cedar creates crisp, elegant lines while delivering reliable performance against moisture and seasonal weather.

Proper window flashing and smooth HardieCraft detailing

For enhanced water protection across the façade, we installed primed flashing with a built-in drippage above each window trim. This directs water away from vulnerable edges and prevents moisture intrusion in Edmonds’ wet climate. Below, the exterior was finished with a 5/4×8 smooth Hardie belly band, creating a clean horizontal break and adding architectural definition while maintaining the durability and low-maintenance benefits of James Hardie fiber cement.

Cedar beam and post wraps for a warm architectural finish

The entire fascia was removed and replaced after significant dry rot was discovered along the roofline. Installing new, properly primed fascia boards ensured a solid, stable foundation for the updated exterior trim and prevented further moisture damage. Replacing the full run—rather than patching—provides long-term protection and is especially important for homes in Edmonds’ damp, coastal climate.
