What a House Wash Will — and Will Not — Remove
A professional house wash can make a dramatic difference in how your home looks. But like any service, it has limits.
One of the most important parts of our job is helping homeowners understand what results to expect before we ever start. Clear expectations lead to happy customers.
What a House Wash Will Remove
Our soft washing process is designed to safely eliminate organic growth and surface buildup, including:
Green and black algae
Mold and mildew
Pollen and airborne dirt
Spider webs and insect residue
General grime from weather exposure
These are the most common causes of discoloration on siding, and they respond extremely well to soft washing. In many cases, homes look nearly new again after cleaning.
What a House Wash Will Not Remove
Some stains are not organic and cannot be removed through standard house washing alone. These include:
Oxidation (chalky or faded siding)
Paint drips or overspray
Rust stains
Oil or grease stains
Permanent discoloration from sun damage or age
Artillery fungus
These issues are often embedded into the material itself — not sitting on the surface.
Why Certain Spots May Not Come Off
If a spot doesn’t come off during a house wash, it’s usually because:
The stain is non-organic
The material has deteriorated or faded
The discoloration is part of the siding, not on it
Attempting to remove these with aggressive pressure or chemicals can cause damage, which is something we actively avoid.
Our Philosophy on Results
We clean homes the safest way possible — not the most aggressive way.
That means:
No unnecessary high pressure on siding
No harsh methods that risk damage
No “forcing” stains off at the expense of your home
If something won’t come off safely, we’d rather leave it than risk costly repairs.
How We Handle Expectations Up Front
Whenever possible, we:
Point out areas that may not fully clean beforehand
Explain what’s organic vs. permanent
Set clear expectations before the job begins
If you ever have questions about a specific stain or area, just ask. We’re always happy to explain what’s happening and why.
The Bottom Line
A house wash removes what nature puts on your home — not damage, wear, or permanent staining.
When done properly, it dramatically improves curb appeal while protecting your siding for the long term.
If you’re unsure whether something will come off, we’ll give you an honest answer every time.
