Is soft washing safe for vinyl siding in Corvallis?

Yes. Soft washing is the manufacturer-recommended cleaning method for vinyl siding. GreenTree Services uses pressure under 1,000 PSI with biodegradable cleaning solutions that kill mold, mildew, and algae without warping, cracking, or forcing water behind siding panels. High-pressure washing can damage vinyl siding, which is why we exclusively use soft washing for all house washing in Corvallis.

How often should I have my Corvallis house washed?

Most Corvallis homes should be soft washed once per year. Properties with heavy tree canopy, north-facing walls, or locations in high-humidity areas like South Corvallis near the Marys River may benefit from washing every 8 to 10 months. Annual house washing prevents permanent staining and extends the life of your siding and exterior paint.

What is the difference between house washing and pressure washing?

House washing uses soft wash techniques at under 1,000 PSI with specialized cleaning solutions to safely clean siding. Pressure washing uses 2,500 to 4,000 PSI cold water for hard surfaces like concrete driveways. Using high-pressure washing on house siding can cause serious damage. GreenTree Services provides both soft wash house washing and high-pressure concrete cleaning in Corvallis.

Can house washing remove black streaks from my siding?

Yes. Black streaks on siding are typically caused by Gloeocapsa magma, a type of cyanobacteria that thrives in Corvallis's humid climate. Our soft washing solutions are specifically formulated to kill and remove this bacteria along with mold, mildew, and algae. Most black streaks are completely eliminated in a single treatment.

Will house washing damage my landscaping?

No. GreenTree Services uses biodegradable, EPA-approved cleaning solutions that are safe for plants and landscaping. Before beginning any house wash, we thoroughly pre-wet all landscaping and cover sensitive plants. After cleaning, we rinse all surrounding vegetation. Our solutions break down naturally and will not harm your Corvallis garden or lawn.

Does GreenTree wash cedar shake and wood siding?

Yes. Cedar shake and natural wood siding are common in Corvallis and require specialized care. We use extra-low pressure and pH-balanced cleaners that remove algae, moss, and weathering without raising wood grain or stripping natural oils. Our process restores cedar's natural color and prepares it for staining or sealing if desired.
