Service · Soft Washing

The right pressure for delicate surfaces.

Low-pressure, chemistry-based cleaning for the exterior surfaces that high-pressure water would damage — stucco, EIFS, painted finishes, vinyl siding, and roofs.

What it is

Cleaning that removes the staining, not the substrate.

Soft washing is the right answer for any surface a high-pressure stream would damage. Instead of using force, soft washing uses chemistry — biodegradable, runoff-aware soft-wash solutions applied at low pressure (under 500 PSI), with a controlled dwell time that lets the chemistry do the work.

When delivered by drone, soft washing reaches the full exterior envelope — including the parapets, soffits, and high corners traditional ground crews struggle to access without specialized equipment.

  • Under 500 PSI.Safe for stucco, EIFS, paint, and vinyl.
  • Chemistry-driven.Removes mold, algae, and lichen at the root.
  • Drone-delivered.Full envelope reach without lifts.
  • California-compliant runoff.Biodegradable chemistry, containment when needed.

Why drone-based

What aerial delivery changes about soft washing.

Soft washing has been delivered by ground crews for decades. Drone delivery doesn't replace the chemistry — it changes the access economics.

How it runs

Process — soft washing.

Step 01

Surface Assessment

Identify substrate, soiling type (mold, algae, environmental), and runoff path.

Step 02

Chemistry Selection

Match solution strength to surface and soiling. Containment plan if storm drains or sensitive landscaping are nearby.

Step 03

Application & Dwell

Low-pressure controlled application via drone, with appropriate dwell time for the chemistry to lift the soiling.

Step 04

Rinse & Report

Low-pressure rinse, runoff control, then before/after imagery and condition notes delivered.

Compliance

Chemistry handled responsibly.

What we deliver around chemistry & runoff.

Soft washing is chemistry-first cleaning, which means how we handle the chemistry matters as much as how we apply it.

  • Biodegradable formulations selected for the substrate and soiling type — no off-the-shelf household bleach.
  • California runoff awareness — containment, dilution, or capture when storm drains or sensitive landscaping are nearby.
  • Substrate testing when surface compatibility is uncertain — small test patch before the full job.
  • Tenant & landscape protection — pre-rinse of plantings, vehicle relocation guidance, signage.
  • FAA Part 107 on every drone-delivered application.
