San Diego’s coastal climate can be tough on buildings. Salt, sun, moisture and wind deposit grime, encourage mold and erode surfaces over time. A comprehensive exterior cleaning routine keeps your property looking sharp and prevents minor issues from becoming costly problems. Use this checklist to keep every area of your home or business in tip‑top shape.

House and Building Washing

• Siding and stucco: Soft‑washing removes salt, dust and biological growth from vinyl, wood, brick and stucco without damaging finishes.
• Trim and shutters: Gently clean around windows, doors and trim to eliminate cobwebs and pollution buildup.
• Frequency: At least once a year; more often in high‑traffic or coastal areas.

Roof and Gutter Maintenance

• Roof cleaning: Eliminate moss, algae and debris that trap moisture and shorten roof life. Professional soft washing protects shingles and tiles.
• Gutter clearing: Remove leaves and sediment so rainwater can drain properly, preventing leaks and foundation damage.
• Frequency: Inspect twice a year (spring and fall) and clean as needed.

Solar Panel Cleaning

• Boost efficiency: Dirt and pollen can reduce energy output by 10‑25% without regular cleaning. Use purified water and soft brushes to avoid scratches.
• Safety: Let trained professionals handle roof access, harnesses and manufacturer‑approved techniques.
• Frequency: Two to four times per year depending on dust, pollen and proximity to the ocean.

Driveways and Walkways

• Oil and rust removal: Hot‑water pressure washing and specialty cleaners lift automotive fluids and iron stains from concrete and pavers.
• Tire marks and dirt: A rotary surface cleaner evens out stubborn marks and removes sand and soil.
• Frequency: Every six to twelve months, or before stains become permanent.

Deck and Patio Care

• Wood and composite: Use a lower pressure and appropriate detergents to remove mildew and food spills without splintering boards.
• Stone and tile: Clean patios, pool decks and outdoor kitchens to prevent slippery algae and grime.
• Frequency: Twice a year or before sealing/staining.

Dumpster Pads and Parking Areas

• Sanitize and deodorize: Hot‑water degreasing and disinfectants eliminate bacteria, grease and odors that attract pests.
• Wastewater recovery: Capture and filter runoff to protect drains and comply with local regulations.
• Frequency: Weekly or monthly for restaurants and food service; quarterly for retail and office complexes.

Graffiti and Stain Removal

• Rapid response: Removing graffiti quickly deters vandals and restores professional appearance.
• Specialized techniques: Use appropriate pressure, heat and chemicals to lift paint without etching underlying surfaces.
• Frequency: As needed; inspect walls and signage regularly.

Windows and Storefronts

• Glass and frames: Keep windows, doors and storefront glass spotless to maximize natural light and convey professionalism.
• Signage: Clean awnings and signs so your branding stays vibrant and legible.
• Frequency: Monthly or quarterly depending on location and weather.

Building Facades and Signage

• High‑rise exteriors: Professional building washing removes pollutants, bird droppings and cobwebs from multi‑story facades using lift equipment.
• Monuments and architectural details: Use gentle detergents and soft brushes to preserve delicate materials.
• Frequency: Annually or as part of property management schedules.

Other Surfaces

• Fences and gates: Pressure wash wood, vinyl and metal fencing to remove mildew and dirt.
• Outdoor furniture: Clean benches, tables and umbrellas to extend their life and improve aesthetics.
• Outdoor play areas: Keep playground equipment and sports courts safe and sanitary.
