Renshaw Renovation & Restoration in Alpine holds CSLB license #1089874 (B-General Building) and serves San Diego County with kitchen remodels, bathroom renovations, ADU construction, and full-home additions from its base on Japatul Lane near Cleveland National Forest. The company's remodeling scope requires plumbing rough-in for relocated fixtures — a phase coordinated with Alpine-based contractors including Alpine Plumbing & Backhoe Inc on projects involving slab-on-grade re-routes and sewer tie-ins. Structural foundation work utilizes helical pile systems as an alternative to traditional poured footings, reducing excavation impact on Alpine's rocky hillside terrain along the Japatul Valley corridor. Exterior deck and patio builds incorporate natural stone and composite materials sourced through East County suppliers including Alpine Landscape Materials on Tavern Road for retaining walls, flagstone paths, and decorative hardscape. Highest-complexity projects include full ADU construction on helical pile foundations with independent HVAC, electrical sub-panels, and separate sewer laterals meeting County of San Diego ADU ordinance setback and utility requirements.
