Natural Stone Cleaning

What This Service Involves

Natural stone in Northwest landscapes ranges from hard granite to acid-sensitive varieties, and the wrong chemistry can etch or dull it permanently. We identify the stone and choose a pH-appropriate cleaner so calcareous stone is never exposed to harsh acids. Moss and organic film that settle into the natural texture are lifted with dwell time rather than aggressive force. The stone keeps its integrity and shows its natural depth of color.

Benefits

Protects acid-sensitive stone with pH-correct chemistry; Preserves the natural finish and depth of color; Lifts organic growth from textured surfaces safely; Avoids the etching that harsh cleaners cause; Maintains the long-term integrity of the stone

Our Process

1) Identify the stone and test a hidden area; 2) Select a pH-appropriate cleaning solution; 3) Apply and dwell to release embedded growth; 4) Rinse gently and inspect the finish

What Affects the Cost

Stone variety and its chemical sensitivity; Surface area and texture; Extent of moss and organic staining; Testing and extra care requirements; Vertical or hardscape access

Best Time of Year

Summer's drier conditions keep porous natural stone from staying saturated and give sensitive treatments the stability they need.
