Flagstone Patio Cleaning

What This Service Involves

Flagstone patios feature broad, irregular joints that fill with moss and organic matter in Washington's damp climate. We treat and clean both the stone faces and the joint material so the whole surface reads clean rather than patchy. Because flagstone can be soft and layered, we keep pressure low and let the cleaning solution do the work. The finished patio shows warm, natural flagstone tones with clean, defined joints.

Benefits

Clears moss from wide flagstone joints; Protects soft, layered stone from flaking; Restores warm natural flagstone color; Evens out patchy, shaded staining

Our Process

1) Remove debris and loose growth from joints; 2) Saturate stone and joints with a moss treatment; 3) Rinse at low pressure to protect the stone; 4) Refresh joint material and finish evenly

What Affects the Cost

Patio square footage and joint width; Softness and layering of the flagstone; Depth of moss embedded in joints; Joint material refresh required; Optional post-clean sealing

Best Time of Year

Flagstone patios are best cleaned during dry summer stretches so joints and stone dry fully.
