STAINS REMOVED BY PRESSURE WASHING

Biological growths that thrive in damp, shaded environments, often appearing as green, black, or grey films. They are particularly common on siding, roofs (often black streaks), decks, and concrete, and they pose a significant health hazard and degrade surfaces over time.

Stains caused by iron oxides (rust) leaching from metal fixtures (e.g., screws, air conditioning units) or from the minerals naturally present in red clay soil. These require specialized rust removal chemicals.

Hardy, complex organisms that attach tenaciously to porous surfaces, especially roofs, brick, and pavers. They absorb water, causing granular loss on shingles and accelerating surface deterioration.

Hydrocarbon stains left by vehicle leaks, cooking spills, or industrial machinery, common in driveways, garages, and dumpster pads. These are highly resistant to cold water and often require hot water (true power washing) and heavy-duty degreasers.

The general accumulation of environmental dust, soil, mud splatter, and airborne particulate matter (such as pollution) that settles on all exterior surfaces, causing a dull, gray, or brown film.

A chalky residue that forms on painted siding (especially aluminum or vinyl) as the paint binder breaks down from sun exposure. Cleaning removes this powdery layer, restoring the color and preparing the surface for sealing.
