Exterior Cleaning in Columbia, SC — Gutters, Soft Wash, and Bundled Maintenance

Columbia's heat and humidity make exterior cleaning a maintenance necessity, not a luxury. Vinyl siding, brick, stucco, and painted surfaces all accumulate algae, mildew, and pollen that look worse every month. Roofs develop black streaks from Gloeocapsa magma algae that shortens shingle life by feeding on limestone filler in asphalt shingles. Gutters oxidize and develop tiger-stripe staining. Windows build up a film of pollen and hard water deposits that reduces natural light. We clean every exterior surface using the method matched to its material -- soft wash for delicate surfaces, pressure wash for hard surfaces, and specialized treatments for specific stains like rust, red clay, and oxidation.

Our soft wash process uses a professional sodium hypochlorite blend at low pressure (under 500 PSI) to kill biological growth at the root level. The result lasts 2-3 times longer than high-pressure blasting, which only removes surface growth without killing the organism. We pre-wet all landscaping within 10 feet, apply the solution, let it dwell for 5-10 minutes to penetrate mold and algae root systems, then rinse with clean water. North-facing walls get extra attention -- they stay damp longer and grow algae fastest, sometimes needing treatment twice when the rest of the house only needs annual cleaning. Two-story homes require extended wand equipment and add $100-$200 to the base price. Vinyl, brick, stucco, fiber cement, and painted wood surfaces each get the appropriate concentration and pressure setting -- there is no one-size-fits-all approach.

The black streaks on your roof are Gloeocapsa magma algae feeding on your shingles' limestone content. Left untreated, the algae shortens shingle life by 5-10 years and increases attic temperatures because dark algae absorbs more heat than clean shingles. Soft wash roof treatment removes the algae safely without loosening granules or voiding your manufacturer warranty. Results last 2-3 years in Columbia's climate. Gutter brightening removes the black tiger-stripe staining on gutter faces caused by oxidized aluminum and trapped debris runoff. Interior gutter cleaning removes leaves, pine needles, and decomposed organic matter that causes overflow and fascia damage. Both services dramatically improve curb appeal and protect your roofing investment. We inspect gutters during every cleaning and flag any sections that are pulling away from the fascia, have damaged seams, or show inadequate slope.

Forest Acres: Mature tree canopy means heavy shade, accelerated algae growth on north-facing walls, and gutter clogs from oak leaves. Most Forest Acres homes need annual soft washing and semi-annual gutter cleaning. Typical house wash: $350-$550. Shandon and Rosewood: Older homes with a mix of wood siding, brick, and vinyl. Wood surfaces require lower pressure and careful detergent selection to avoid stripping paint. Typical exterior package: $400-$600. Northeast Columbia (Killian Road, Summit): Newer construction with cleaner siding but dustier from ongoing development. Pollen season hits hard April through May. Typical house wash: $250-$400. Downtown and Vista: Commercial facades, mixed-use buildings, and historic properties. Brick requires careful pressure control to avoid mortar damage. Quarterly commercial contracts available. West Columbia and Cayce: Mix of older residential and commercial. River proximity adds moisture that accelerates biological growth on properties nearest the Congaree.

Spring package (March-May): house wash + window rinse + gutter cleanout after pollen season. This is the most popular package and addresses the pollen film, winter mold growth, and leaf debris from fall that overflowed gutter guards. Price: $400-$700 for a standard home. Fall package (September-November): pre-holiday refresh including house wash, driveway, gutter cleanout, and window cleaning. Gets the property looking its best before Thanksgiving and Christmas guests. Price: $500-$900. Annual maintenance contract: two visits per year (spring and fall) with 15-20% savings over booking individually. Quarterly commercial plans for storefronts and multi-family properties at 20-30% monthly savings. The best value is always a bundled package -- setup time is the same whether we clean one surface or five, so adding surfaces to a visit costs less than booking them separately.

We serve Columbia-area retail, office, restaurant, and multi-family properties. Storefront cleaning includes facade, sidewalk, and entry area washing -- first impressions matter for foot traffic businesses. Apartment and condo complexes benefit from building exterior and common area cleaning on a quarterly schedule. Property managers: we coordinate with tenants and schedule around business hours. Restaurant and food-service properties need monthly dumpster pad and grease area cleaning using hot water equipment. Church properties and HOA common areas are cleaned on monthly or quarterly rotation depending on visibility and foot traffic. We work around business hours and can schedule overnight cleaning for high-traffic commercial areas in downtown Columbia and the Vista.

Before we arrive: move any outdoor furniture, decorations, or vehicles away from the areas being cleaned. Close all windows and doors. We handle the rest. On arrival, the crew does a walkthrough to identify any pre-existing damage, note areas of concern, and confirm the scope of work. We pre-wet all landscaping and cover any sensitive plants near the work area. The cleaning process takes 2-4 hours for a standard residential property (house wash + driveway + patio). You don't need to be home, but we need access to an outdoor water spigot. After cleaning, we do a final walkthrough and photograph the results. If any spots need retreatment, we handle it on the same visit. Payment is due after you're satisfied with the results -- never before the work is complete.
