Exterior surfaces are grimy in Pasadena
Grime can build up for several reasons, and the right cleaning method depends on the surface. Use the guidance below to decide when to call a professional and where to go next.
What may be causing the grime
Common possibilities include dust, pollen, traffic residue, soil splashed onto lower walls, or algae and mildew in damp or shaded spots. From the ground, note which surfaces are affected and whether the grime is concentrated near the ground or in shaded areas. Don’t climb a ladder or onto a roof to inspect.
When to bring in a professional
Ask a professional to assess it if grime is widespread, keeps returning, makes a walkway slippery, or appears alongside peeling paint or surface damage. The wrong pressure or cleaning method can harm some siding, paint, wood, or masonry.
Choose a cleaning method that fits the surface
Pressure washing may suit some driveways and exterior surfaces, but it isn’t right for every material. Continue to Pressure Washing, then confirm the provider serves your address and ask what method they recommend for your specific surface.
