Soft Washing in University Heights, San Diego

Soft washing in University Heights cleans stucco, painted siding, and roofs at 100 to 150 PSI instead of high pressure. A sodium hypochlorite mix lifts algae and black streaks, then rinses clean. Most single-story homes run $250 to $500 and take our crew two to three hours.

The blocks off Park Boulevard and Adams Avenue are full of 1920s Craftsman and Spanish stucco homes. That housing stock is exactly what soft washing was built for.

You cannot put a 3000 PSI wand on eighty-year-old stucco. The finish coat is soft, and the paint on the trim is often older than it looks. We drop the pressure and let the chemistry do the work instead.

Why University Heights stucco grows black streaks

North-facing walls near Trolley Barn Park hold moisture from the marine layer well into the morning. That damp shade feeds algae and the dark gloeocapsa staining you see running down under eaves and window sills.

Pressure alone does not kill it. Blast the surface and the stain grows back in months because the spores stay in the pores of the stucco. We treat with a low-pressure soft wash that kills the organism at the root, then rinse.

What a University Heights soft wash covers

We clean the body of the house, the eaves, the trim, and the entry stucco. On a typical two-bedroom bungalow near El Cajon Boulevard, that is a two hour job at 100 to 150 PSI. Painted wood siding on the older cottages gets the same gentle treatment.

Cost runs $250 to $500 for a single-story home, more if the house is two stories or the streaking is heavy on multiple elevations. Many of these lots share a zero lot line with the neighbor, so we stage hoses carefully and keep overspray off the adjacent property.

For hard surfaces like the driveway and front walk, that is a different tool. See our University Heights pressure washing page for concrete work, or our main soft washing page for how the process works. Ready for a quote? Reach us through the contact page.

Integrity Pro Washers works University Heights, Normal Heights, and North Park most weeks. If we soft washed your stucco off Adams Avenue, we would love a Google review that mentions your street and the work we did.
