Neighborhoods We Serve
Siding Across Mill Valley Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.
Scott Highlands
Scott Highlands homeowners frequently choose Hamilton Exteriors for siding. Redwood siding is signature Mill Valley but requires restaining every 5-7 years minimum in the fog belt. With Mill Valley's Heavy fog May-September, burns off by mid-morning but returns late afternoon, material selection in Scott Highlands requires local expertise.
Tamalpais Valley
Tamalpais Valley's fog belt location creates persistent moisture that deteriorates wood siding quickly. We replace failing exteriors with James Hardie fiber cement boards engineered for coastal California, including proper rainscreen detailing to prevent the moisture trapping common in this area.
Cascade Canyon
Cascade Canyon's WUI (wildland-urban interface) location requires fire-rated exterior cladding. James Hardie fiber cement siding provides Class A fire resistance and holds up against the heavy moisture and debris exposure common in this forested Mill Valley canyon.
Alto
Alto's hillside homes benefit from durable siding that handles both sun exposure on south-facing walls and moisture on shaded north sides. We specify Hardie products in profiles that suit Alto's mix of midcentury and contemporary residential architecture.
