Stone Cleaning

What This Service Involves

Stone veneer and stonework across the Northwest collect moss in the crevices and a dull film on the faces from constant moisture. Different stones react differently, so we adjust chemistry and pressure to avoid dulling a polished face or eroding a soft stone. Textured stone in particular hides growth deep in its surface, requiring dwell time rather than force. The cleaned stone shows its natural variation and color again.

Benefits

Tailors the method to the specific stone type and finish; Draws growth out of deep-textured surfaces; Avoids dulling or eroding softer stones; Restores the natural color variation of the stone; Cleans crevices that trap moss and debris

Our Process

1) Identify the stone type and test a discreet area; 2) Apply the appropriate cleaning solution; 3) Allow dwell time for textured and porous stone; 4) Rinse at a stone-safe pressure and inspect

What Affects the Cost

Stone type, finish, and porosity; Surface area and texture depth; Extent of moss and film buildup; Vertical height and access; Sensitivity requiring extra testing and care

Best Time of Year

A drier summer schedule keeps porous stone from staying saturated, giving the cleaning solution the best conditions to work.
