Frequently Asked Questions

Gloeocapsa magma, a heat-loving algae, feeds on limestone filler in asphalt shingles and thrives in South Florida's moisture and warmth. The dark streaking holds heat, accelerates granule breakdown, and spreads across the roof surface. Low-pressure chemical treatment removes the organism without damaging shingle integrity or dislodging protective granules.

Stucco, painted wood, Dryvit, and aluminum siding have weep holes, seams, and finishes that high pressure can penetrate or strip. Soft washing uses low-pressure detergent application, dwell time to break down algae and mildew, then a high-volume rinse. This method cleans without forcing water behind the cladding or peeling paint.

Palm Beach County's year-round heat and moisture create ideal conditions for algae, mildew, and organic growth on roofs, siding, concrete, and wood surfaces. Homes near water or heavy shade accumulate buildup faster. Most properties benefit from annual cleaning, while north-facing walls and shaded walkways may need attention every six to nine months.

Gutter cleaning removes leaves, sludge, and debris from inside the trough and flushes downspouts to restore proper drainage. Gutter brightening addresses dark tiger stripes on the exterior aluminum caused by bonded oxidation, which requires specialized chemistry rather than pressure alone. Properties often need both services to restore function and appearance.

Yes, if aggressive pressure is used. Direct spray dislodges protective granules, shortens shingle life, and can void manufacturer warranties. ARMA guidance supports low-pressure chemical application that kills Gloeocapsa magma without mechanical abrasion. Roof cleaning should prioritize organism removal over force, leaving granule coverage intact.

Algae and organic film grow on concrete and asphalt in humid climates, creating a biofilm layer that holds moisture and reduces traction. High foot or vehicle traffic grinds the film into the surface texture. Rotary surface cleaning with pretreatment removes embedded buildup, restores slip resistance, and prevents the slick layer from reforming as quickly.

Technicians apply biodegradable detergent at low pressure to siding, soffits, and trim, allowing dwell time to break down algae, mildew, and organic stains. Landscaping is pre-wetted and protected from runoff. A high-volume rinse removes loosened contaminants without forcing water into weep holes or behind cladding, leaving surfaces clean and streak-free.

Composite materials require lower pressure and pH-neutral cleaners to avoid surface scratching or texture damage. Wood decking tolerates slightly higher pressure but can fur if the angle or distance is wrong. Pre-wetting, controlled spray patterns, and surface-specific chemistry remove algae and grime while preserving the substrate finish.

Dumpster pads accumulate grease, food residue, and organic material that standard cold water and pressure won't fully remove. Hot water breaks down oils, degreasers lift bonded contaminants, and controlled rinsing directs runoff into drains. Sanitizer application reduces odor and conditions that attract pests, keeping service areas cleaner between visits.

Schedule cleaning as soon as black streaking appears, before Gloeocapsa magma spreads across the roof plane. The algae retains heat, accelerates shingle aging, and feeds on limestone filler within the asphalt layer. Annual or biennial cleaning in South Florida prevents organism colonization and extends roof lifespan without repeated granule loss.

Wand-only cleaning creates overlapping spray patterns that show as light and dark bands once the surface dries. Commercial rotary surface cleaners use spinning nozzles under a shroud to deliver even coverage and consistent cleaning across the slab. Proper edging, uniform speed, and appropriate pressure prevent striping and produce a uniform finish.

Building height, facade material, accessibility, gum and spider web density, and scheduling constraints all influence pricing. Stucco and painted surfaces require soft washing, while concrete block may tolerate higher pressure. Properties with landscaping, awnings, or signage need additional prep and protection. Frequency contracts reduce per-visit costs compared to one-time cleanings.
