Frequently asked questions

They are not the same job. Pressure washing uses high-powered water — often 3,000 PSI or more — to blast dirt, grime, mildew, and stains off a surface. Soft washing uses low water pressure plus a cleaning solution. The solution sits, breaks down algae, mold, mildew, and moss, then we rinse it away.

Pressure washing is brute-force cleaning for hard surfaces. Soft washing is chemistry-first cleaning for surfaces that high pressure can ruin.

For more detailed information, read about pressure washing vs. soft washing in the Resource Center.

A simple rule of thumb: hard, ground-level surfaces usually want pressure washing. Roofs, siding, and anything painted or delicate want a soft wash.

• Driveways, sidewalks, patios, brick, stone, and similar flatwork — pressure washing
• Roof shingles, vinyl or wood siding, painted surfaces, stucco — soft washing

Yes. High pressure on the wrong surface can cause expensive damage. We choose the method surface by surface instead of running one machine across the whole property.

• Roofs: high pressure can crack shingles, strip granules, and drive water underneath
• Siding: aggressive pressure can force water behind panels and into the walls
• Wood: high pressure can etch or gouge softer boards
• Paint: pressure can strip the finish and leave a patchy exterior

Yes — as a soft wash on 1-story buildings only, priced by square footage. We clean shingle, tile, and metal roofs. Soft washing kills the algae that makes those black streaks, instead of blasting granules off the shingles. We use specialized equipment so we do not need to walk on the roof.

The Services page shows typical ranges so you have a ballpark. Your written estimate depends on size, condition, and the stains we need to treat — oil, grease, heavy iron, or red clay can move the number. Oxidation removal is priced in person because difficulty varies so much.

The term “solutions” can often raise questions. We pre-wet or cover landscaping, use lower concentrations, and rinse thoroughly afterward.

If you are worried at all, ask your specialist about the dilution process or our plant protection procedures.

Typical guidance is once a year for siding and roofs (more often in humid or shaded climates prone to algae and mold), and every 1–2 years for driveways, walkways, and patios, depending on traffic and staining.
