Pressure Washing
That's Actually Safe for Your Home or Business

Pressure washing uses high-pressure water to blast away surface dirt and is best for hard, durable surfaces like concrete driveways, sidewalks, and brick patios. Soft washing uses low-pressure water combined with specialized cleaning solutions to safely kill organic growth at its root.

For delicate surfaces like vinyl siding, stucco, painted wood, and roof shingles, we use soft washing to prevent costly material damage.

No. Our roof soft washing uses a dedicated low-pressure delivery system that safely eliminates black streaks, moss, and lichen without stripping the protective asphalt granules from your shingles.

Our soft-wash approach uses low-pressure delivery with cleaning solutions designed for exterior surfaces — they target organic growth, not surrounding landscaping.

The black streaks are a destructive form of blue-green algae called Gloeocapsa magma. They should never be cleaned with high pressure, which will tear your shingles and cause premature leaks.

We treat them with a low-pressure soft-wash process that kills the algae completely, preventing it from turning into a breeding ground for moss and lichen roots.

Cost depends on total square footage, the number of stories, and the specific surfaces being cleaned. Because every property is different, we provide fast, transparent quotes tailored to your home.

Most homes should be professionally washed once a year to keep them looking their best. Homes with heavy tree coverage, excess moisture, or algae buildup may benefit from being washed twice a year.

You can — but most DIY rentals don't include the specialized cleaning solutions needed to actually kill algae, mold, and Gloeocapsa magma at the root. Without the right solution, surface dirt comes off but the organic growth returns within months.

High-pressure DIY equipment can also damage vinyl siding, strip roof granules, or break window seals — repairs that often cost far more than a professional soft wash.

Soft washing and pressure washing are safe and effective year-round in our climate. Spring and summer are popular, but fall and winter are excellent times to remove built-up algae and prepare your property before the next growth cycle.

We schedule jobs every month of the year.
