Professional Cold Washing for Every Surface
Serving Willis & Surrounding Areas
What Is Cold Washing?
A safe, versatile alternative to high heat
Cold washing is professional pressure cleaning using ambient‑temperature water, dialed‑in pressure, and purpose‑built detergents to lift soils without the risks of high heat. It’s ideal for painted and powder‑coated surfaces, vinyl siding, concrete, pavers, wood, and natural stone, effectively removing dirt, mildew, algae, pollen, soot, and surface oxidation.
Compared with hot water, cold washing reduces chances of warping, etching, or loosening joints and sealants while still achieving deep cleaning through mechanical action and chemistry. When applied by trained technicians, it restores curb appeal, protects coatings and substrates, and prepares surfaces for sealing or painting.
Complete cold water cleaning for properties
Sigma Pressure Washing Services provides full‑scope cold washing: whole‑home soft washing, driveway and sidewalk cleaning, brick and stucco washing, deck and fence care, pool decks and patios, screen enclosures, outdoor furniture, gutters, soffits and fascia, and light commercial exteriors such as storefronts and walkways.
Every job is tailored to the material and soil load. We select the correct nozzles and pressure ranges, pre‑treat organic growth with eco‑friendly surfactants, agitate where necessary, and perform controlled, low‑pressure rinsing. Protective measures include covering outlets and fixtures, safeguarding landscaping, and final post‑wash inspection.
Pro-grade tools, trained technicians, proven steps
Our process starts with a detailed inspection to identify substrate type, oxidation, coatings, and sensitive features like weatherstripping or hairline mortar joints. We test in inconspicuous areas, map run‑off pathways, and choose tip angles and PSI appropriate to each surface to prevent damage while maximizing cleaning efficiency.
Technicians arrive with commercial belt‑drive washers delivering 2–8 GPM and adjustable pressure, surface cleaners for flatwork, telescoping and soft‑wash wands for elevation work, and metered detergent systems for precise dilution. Where spot‑free results are critical, we can implement filtered final rinses to minimize mineral spotting.
Chemistry and safety are prioritized: biodegradable, pH‑balanced detergents matched to organic or inorganic soils; controlled dwell times; and thorough rinsing. We manage overspray and runoff, follow manufacturer care guidelines for each material, and work to extend the service life of coatings and substrates through correct technique.
