What is drone stucco cleaning?+
An FAA Part 107-licensed pilot flies a tethered industrial drone carrying a low-pressure soft-wash spray head. The drone applies biodegradable detergent and pure-water rinse to stucco facades from the air — reaching the full envelope, including parapets, soffits, and architectural details, without scaffolding or boom lifts.
Why is pressure washing bad for stucco?+
Stucco is a thin cementitious finish over lath or block. High-pressure water strips the surface texture, opens hairline cracks wider, and forces water behind the cladding where it can rot sheathing and feed mold inside wall cavities. On painted stucco it strips the paint film. On elastomeric or acrylic coatings it tears the membrane. Soft-wash chemistry cleans deeper without any of that mechanical damage.
What causes the black streaks on Miami stucco?+
Almost always Gloeocapsa magma — a cyanobacteria that thrives on South Florida's humidity, UV, and airborne calcium/limestone dust. It looks like dirt or soot but it's alive. Pressure washing only blasts the visible layer; the organism grows back within months. Soft-wash kills it at the root so the streaks stay gone.
Is drone soft-wash safe for elastomeric and acrylic coatings?+
Yes. Soft-wash chemistry is pH-matched to the coating and applied at sub-500 PSI — well below the rupture threshold for elastomeric membranes and acrylic finish coats. There's no mechanical impact to lift the coating from the substrate.
Does drone cleaning damage paint on painted stucco?+
No. Pressure washing strips paint; soft-wash chemistry plus pure-water rinse does not. The detergent breaks down algae and atmospheric soiling without attacking the paint film. We've cleaned thousands of square feet of painted stucco in Miami without lifting a single coat.
How long do drone stucco cleaning results last?+
On Miami stucco: 18–36 months before visible algae return, depending on tree shade, irrigation overspray, and oceanfront exposure. Pressure washing on the same stucco lasts roughly 6 months because the spores survive and recolonize. The chemistry, not the pressure, drives the duration.
How much does drone stucco cleaning cost in Miami?+
$0.10–$0.20 per square foot of wall area. A 10,000 sqft mid-rise stucco facade typically runs $1,500–$2,500; a 50,000 sqft condo tower runs $7,500–$12,000. Pricing is fixed after a free site survey and includes substrate-matched chemistry, pure-water rinse, and 4K aerial documentation.
How long does a stucco cleaning project take?+
Single-story commercial strips: a few hours. Mid-rise (4–10 stories): 1 day. High-rise condos and office towers: 1–3 days. The drone covers far more facade per day than ground crews because there's no rigging setup and no walking elevations.
What insurance do you carry?+
We carry $2M commercial general liability plus dedicated UAS (drone) liability and hull coverage. Certificates of insurance naming the building owner, property manager, and HOA or condo board are issued before mobilization.
Do you need permits or FAA authorization?+
Most Miami-Dade, Broward, and Palm Beach municipalities do not require special permits for FAA Part 107 operations on private commercial property. For controlled airspace near MIA, FLL, and PBI we file LAANC airspace authorization with the FAA before mobilization.
Can you clean stucco on an occupied building?+
Yes. No scaffolding, no swing stage, no lobby disruption. Tenants get a 48-hour notice and the drone works one elevation at a time. Pedestrian access and business operations continue normally throughout.
What about stucco with hairline cracks or prior pressure-wash damage?+
Soft-wash chemistry will not enlarge existing cracks — it has no mechanical impact. We document any pre-existing damage during the pre-job survey and note it in writing. For severely compromised stucco, we recommend repair and recoat before cleaning so the new finish doesn't immediately re-soil.
