Chemical Treatment

What This Service Involves

The foundation of effective soft washing is the right detergent or solution matched to the specific contaminant on the surface. We select and dilute cleaning agents to tackle algae, mildew, and organic staining common on shaded Northwest exteriors. Allowing the solution proper dwell time lets it penetrate and break down growth before a gentle rinse carries it away. Correct chemistry means surfaces come clean at low pressure, protecting both the material and surrounding plants.

Benefits

Matches the cleaning solution precisely to each contaminant; dissolves algae, mildew, and organic stains at the source; enables effective cleaning at low, surface-safe pressure; protects materials and landscaping through careful dilution

Our Process

1) Identify the growth or stain and the surface material; 2) Select and dilute the appropriate cleaning solution; 3) Apply and allow proper dwell time to break down the contaminant; 4) Rinse gently and confirm the surface is clean and undamaged

What Affects the Cost

Area requiring chemical application; type and severity of the growth or staining; surface sensitivity and dilution requirements; landscaping protection needed nearby; number of applications to fully resolve the problem

Best Time of Year

Works throughout the year, with the wet Northwest seasons driving the most demand for treating active organic growth.
