Georgia's humidity and seasonal pollen create algae, mildew, and grime buildup that typically requires annual pressure washing. Homes with significant tree cover or north-facing sides may need cleaning twice yearly. Spring and fall are ideal because they follow pollen season and precede winter moisture.

Pressure washing uses high-pressure water to remove dirt and stains from concrete, brick, and hard surfaces. Soft washing uses low-pressure application with cleaning solutions for delicate surfaces like siding, roofs, and painted wood. The wrong method damages surfaces—vinyl siding cracks under high pressure, while concrete needs force to remove oil stains.

High pressure applied incorrectly cracks vinyl, strips paint, and forces water behind siding where it causes mold and rot. Proper technique uses appropriate pressure levels, correct nozzle angles, and controlled distance. Experienced operators adjust pressure based on surface age and condition to clean effectively without damage.

Algae, mildew, and moss thrive in Georgia's warm, humid climate and colonize porous concrete surfaces. These organisms feed on organic debris and moisture trapped in concrete pores. Once established, they spread quickly and create slippery surfaces that require pressure washing to remove completely.

Close all windows and doors, remove outdoor furniture and potted plants from work areas, and clear walkways of obstacles. Move vehicles out of driveways if they're being cleaned. Disconnect or cover exterior electrical outlets, and inform the crew about any loose siding, damaged wood, or previous leak areas.

High-pressure water and runoff can damage flower beds, erode mulch, and stress delicate plants. Professional operators pre-wet plants, use tarps or barriers for protection, and rinse vegetation afterward to remove cleaning solution residue. Hardy shrubs typically tolerate pressure washing better than annuals or new plantings.

Wood decks require lower pressure and specific techniques to avoid splintering, gouging, or raising grain. Cleaning follows the wood grain direction, uses wider spray patterns, and may include brightening treatments after washing. Composite decking needs even gentler pressure since high force can damage the material's surface texture.

Spring and fall offer ideal conditions—moderate temperatures help cleaning solutions work effectively without evaporating too quickly. Avoid winter when freezing temperatures can turn residual water to ice. Summer works but requires early morning or late afternoon scheduling since midday heat causes rapid drying and streaking.

Fresh oil stains respond to hot water pressure washing and degreasers, but old stains penetrate deep into concrete pores where pressure alone can't reach them. Pre-treatment with specialized chemicals breaks down petroleum bonds before washing. Complete removal of set-in stains often requires multiple applications or may leave faint shadows.

Siding regains its original color, windows look clearer without grime film, and walkways lose slippery algae coatings. Gutters drain properly once downspout openings are cleared, and paint or stain adheres better to cleaned surfaces. Mold and mildew odors near entry points typically disappear after exterior cleaning.
