Pressure Washing (S03)

Pressure washing restores appearance and prevents damage – essential in Utah where dust, hard water stains, and de-icing salt accumulate on exterior surfaces.

This BidScope guides you through pressure washing applications: house siding (vinyl, brick, stucco, wood), driveways and walkways (concrete, pavers, asphalt), decks and fences (wood, composite, PVC), and commercial surfaces (storefronts, parking lots).

Learn pressure washer specs: PSI (pounds per square inch, force of water, 1,300-4,000 residential), GPM (gallons per minute, cleaning speed, 1.5-4 typical), gas versus electric (gas more powerful mobile, electric quieter lighter maintenance), hot versus cold water (hot removes grease and oil, cold sufficient for most residential).

Understand surface-appropriate pressure: vinyl siding (1,300-1,600 PSI, wider spray tip, avoid forcing water behind), brick and stone (2,000-3,000 PSI, remove mold and efflorescence), concrete (2,500-4,000 PSI, oil stains and tire marks), wood decks (500-1,200 PSI, along grain, strip old stain).

Master nozzle selection: 0-degree red (concentrated jet, stripping paint and concrete, dangerous on soft surfaces), 15-degree yellow (medium angle, concrete and hard surfaces), 25-degree green (wider spray, general purpose, siding and fences), 40-degree white (gentle wide spray, delicate surfaces like windows), soap nozzle black (low pressure for detergent application).

Navigate cleaning solutions: house wash (mild detergent, mildewcide for mold and algae), degreaser (oil stains on concrete, driveways and garages), deck cleaner (oxalic acid for tannin stains, brighten wood), concrete cleaner (remove efflorescence and hard water, restore appearance).

Learn technique: pre-wet (saturate surface before detergent), apply detergent bottom-up (prevents streaking, dwell time 5-10 minutes), rinse top-down (prevent streaking, overlap strokes), maintain distance (12-18 inches typical, closer for stubborn stains), consistent motion (avoid tiger striping, smooth overlapping passes).

Understand Utah-specific challenges: hard water stains (mineral deposits on siding and concrete, acid wash may be needed), de-icing salt residue (white chalky appearance, flush thoroughly), dust accumulation (dry climate, frequent buildup, pre-wet critical), altitude and sun damage (UV fading, pressure too high damages weak surfaces).

Know safety considerations: eye protection (debris and water splashback), sturdy footwear (slip hazards, chemical exposure), electrical safety (GFCI outlets for electric washers, keep connections dry), chemical handling (read labels, proper dilution, protective gloves).

Navigate scheduling and frequency: annual washing (maintain appearance, prevent buildup), spring cleaning (winter salt and grime), before painting or staining (clean surface ensures adhesion), event preparation (weddings, parties, open houses).

Learn damage prevention: avoid direct spray on windows (broken seals, water intrusion), protect plants (cover or rinse immediately, detergent can damage), electrical fixtures (cover outlets and lights, water intrusion risk), control water direction (away from foundation and vents).

Calculate typical costs: DIY washer rental $50-100 per day, detergent and chemicals $20-50, professional service (house washing $200-500 depending on size and height, driveway 500 sq ft $100-200, deck 300 sq ft $150-300).

This tool ensures pressure washing is done safely and effectively for Utah’s unique cleaning challenges.
