retaining walls & decorative boulders
Structural stonework that shapes your terrain, controls erosion, and adds dramatic natural beauty to your estate's landscape.
THE SERVICE
Structural strength with natural elegance
Napa Valley and Sonoma County's hillside properties require expert retaining wall construction walls that manage significant soil loads, handle the region's winter rains, and integrate naturally into the surrounding landscape. A poorly built retaining wall is a liability. A well-built one is a landscape feature in its own right.
Clerici builds retaining walls in natural dry-stack stone, mortared fieldstone, engineered boulders, and premium concrete systems each appropriate for different scale and aesthetic requirements. We handle the engineering, drainage, and installation to create walls that are structurally sound, visually beautiful, and built to last generations.

- Engineered boulder placement for dramatic natural effects
