San Ramon’s hot Tri-Valley summers, cool evening delta breezes, and occasional winter storms can punish siding and trim. We start with a 3,000-PSI pressure-wash to remove dirt, dust, and mildew. Then we repair or epoxy dry-rot, countersink stray nails, scrape and sand peeling paint, and spot-prime bare stucco, wood, or Hardie® siding with Sherwin-Williams Loxon or Multi-Purpose Primer. After masking landscaping and hardscapes, we spray or roll two full coats of Emerald or Duration Exterior in your HOA-approved colors. Elastomeric caulking seals vertical joints for lasting water resistance, and UV-blocking pigments keep colors vivid for years. Every San Ramon project ends with a detailed walk-through and a written workmanship warranty.
