Why this work is its own category.
Natural stone patios — slate, bluestone, sandstone, flagstone — vary widely in porosity, sealer compatibility, and pressure tolerance. Cleaning one material as if it were another (sandstone with bluestone settings, for example) can permanently damage the surface. Stone patio work requires identification, calibration, and chemistry chosen for the specific stone in front of the crew.
In Los Altos Hills, the conditions of the Mid-Peninsula hillside market sharpen the need. Native stone — bluestone, sandstone, slate — appears frequently in Los Altos Hills landscape design, and identification per area of the patio matters more here than in markets with uniform paver installations.
The partner’s approach
How stone patio care is handled.
- Material identification per area of the patio (often multiple stones used together).
- Pre-treatment chemistry selected for the most porous material in the work area.
- Surface-calibrated pressure with attention to joint composition (sand, mortar, or open).
- Sealer status assessment and separate quote for resealing if the original finish has worn.
When to call
Scenarios where this service is the right answer.
- Annual maintenance on stone patio surfaces, often timed with the dry season.
- Pre-event where the patio will host guests.
- After heavy organic shed or biological staining has set into the surface.
- Before resealing or restoration work that requires a clean substrate.
