If you're seeing dark patches or green buildup on your siding, you don't need to figure out a species name before asking about cleaning. Tell us where it is and what you'd like cleaned. Osborne Pro Wash uses soft washing for House Washing, with the surface and its condition considered before the work is agreed.

A dark patch doesn't tell the whole story
Color is useful for describing what you see, but it doesn't confirm what the growth is. The CDC's mold guidance explains that mold can appear in many colors. We don't identify a particular type or determine a health risk from a siding photo.
For a cleaning request, start with what you know. Is it spread across a wall or concentrated in one spot? Is the shaded side different from the rest of the house? A wider photo and a closer view can help us understand the concern. Take them from the ground; there's no need to climb for a quote photo.
Photos are optional, and they're especially helpful for areas we can't see from the street. Include your property address, contact details and the work you'd like considered. Pricing depends on the home's size, access, surfaces and condition, rather than one patch alone.
Soft washing the siding
Our House Washing service uses professional cleaning solution and soft washing to clean exterior buildup. We don't pressure wash the house. You can read more about the work in the House Soft Washing Guide.
Let us know about loose or damaged siding, known repairs and any sensitive areas around the house, including trim or plants you want to discuss. Cleaning and repairs are different needs. Explaining those details early helps us talk clearly about the work you want done.

If you're also concerned about moisture indoors
House Washing is exterior cleaning. It doesn't find the cause of an indoor moisture problem, repair a leak or provide indoor mold remediation. If you have those concerns as well, arrange a separate assessment with the appropriate qualified professional. Health questions belong with a healthcare professional.
The EPA explains that moisture control is central to mold control. Cleaning the siding isn't a substitute for addressing a continuing water problem. Keep those concerns separate from the exterior surfaces you'd like us to clean.
Deciding when to have the house washed again
Outdoor buildup can return. There isn't a fixed number of months we can promise that the house will stay free of growth or debris. Shade, moisture and trees affect the conditions, and your preference is the biggest factor in how often you want it cleaned.
For homeowners who want a consistently clean appearance, Kyle recommends at least yearly. Some customers prefer spring and fall, particularly on wooded properties with bugs, webs and tree debris. Others choose every two or three years as they see the need. Our House Washing frequency article explains those choices.
