Exterior Cleaning Near Me in Columbia & Lexington SC — What's Included and What to Ask

Exterior cleaning covers a broader scope than pressure washing alone. It includes soft washing house exteriors, roof cleaning, gutter brightening, window exterior cleaning, and concrete/paver washing. Not every company offers all services, and not every company knows the difference between soft washing and pressure washing. The wrong method on the wrong surface causes expensive damage. Ask specific questions about their process before hiring.

Columbia and Lexington’s subtropical humidity grows algae, mildew, and mold on every exterior surface. Pressure washing blasts the growth off the surface temporarily, but soft washing kills it at the root level with professional detergents. Results from soft washing last 2–3 times longer. Any company that pressure washes your vinyl siding, roof, or painted surfaces is risking damage — these surfaces need low pressure and chemical cleaning.

Vinyl siding: soft wash only (under 500 PSI). High pressure forces water behind lap joints, causing mold growth inside walls. Brick: medium pressure (1,000–1,500 PSI) with a wide-angle tip. Avoid high pressure near mortar joints on older brick. Concrete driveways: high pressure (2,500–3,000 PSI) with surface cleaner attachment for even results. Stained concrete and pavers: low-to-medium pressure with an appropriate degreaser. Wood decks: low pressure (600–800 PSI) with a fan tip, never a zero-degree tip. Roofs (asphalt shingles): soft wash only — pressure washing voids most shingle warranties and strips granules. Metal roofing: soft wash with mildew treatment. Windows: low-pressure rinse, never direct pressure, which breaks seals on double-pane units.

A full exterior cleaning visit typically covers: house exterior (soft wash), driveway and sidewalks (pressure wash), patio or pool deck, and gutter face brightening. Some companies add roof cleaning and fence cleaning as add-ons. The process takes 3–6 hours for a standard residential property. Before work begins, all landscaping is pre-wetted for plant protection. After cleaning, a final rinse removes any residual solution.

House wash (soft wash): $250–$500. Roof cleaning: $300–$600. Driveway: $150–$250. Patio: $100–$200. Gutter brightening: $75–$150 per 100 linear feet. Full exterior package: $500–$1,000 with 15–22% bundle savings. Commercial properties are priced by scope. Annual maintenance contracts reduce per-visit cost and keep your property consistently clean year-round.

Five questions that separate professional operators from damage risks. First: do they carry general liability insurance and can they provide a certificate? Second: do they soft wash siding and roofs, or pressure wash everything? (If the answer is "we pressure wash everything" — walk away.) Third: do they pre-wet landscaping and use plant-safe detergents? Fourth: do they use a surface cleaner on driveways, or a wand? (A wand leaves stripe marks; a surface cleaner produces even results.) Fifth: will they walk the property with you before starting and point out anything that needs special treatment — loose siding, cracked mortar, delicate window screens? A company that skips the walkthrough skips other things too.

Spring (March–April) is the most popular window — cleaning off winter's accumulated algae, pollen, and dirt before the outdoor season starts. However, fall (September–October) is often the smarter choice: crews are less booked, pricing is more competitive, and cleaning before winter prevents organic growth from embedding deeper during cold, damp months. The worst time to clean is mid-summer (July–August) — chemicals dry too quickly in 95°F heat, reducing effectiveness, and crews work shorter days to avoid heat illness. If you notice green or black streaks on your siding, don't wait for the "right" season — algae gets harder to remove the longer it sits.
