Exterior Cleaning FAQs

Price comes down to the size of the area, how many surfaces are included, and how much buildup has accumulated over time. A house wash, a roof cleaning, and a driveway are each quoted separately based on square footage and access. We give you a firm, upfront price before any work starts, so there are no surprises at the end.

Pressure washing relies on high-force water alone, which can strip paint, drive water behind siding, splinter wood, and blast roof granules loose. Soft washing uses a low-pressure rinse paired with a cleaning solution that kills algae, mold, and mildew at the root. The result lasts longer and the surface underneath — siding, shingles, wood, or stucco — stays undamaged.

Yes. We use biodegradable cleaning solutions and pre-wet and rinse landscaping before and after treatment to protect grass and shrubs. Pets should stay inside during the cleaning, then are free to be back outside shortly after we rinse. On roofs specifically, soft washing is the method shingle manufacturers actually recommend, since it cleans without stripping granules or shortening the roof's life.

Most homes in Mobile and Baldwin County benefit from a house wash every 12 to 18 months. Our humidity and rainfall give algae and mildew ideal growing conditions, so exteriors here get dirty noticeably faster than in drier climates. Homes with heavy shade or facing the water sometimes need it closer to once a year.

No, as long as it's done correctly. We saturate lawns and planting beds with fresh water before we begin and rinse them again afterward, which dilutes and washes away any solution that drifts over. Our cleaning products are also formulated to break down quickly, so they don't linger in the soil the way some commercial chemicals can.

Not necessarily. Many customers give us access instructions and go about their day while we work. We just ask that windows and doors be closed, pets are kept inside, and any patio furniture or delicate items near the work area are moved or covered ahead of time. We'll call when we're on the way and again when the job is complete.

Because soft washing kills algae and mildew at the root rather than just rinsing the surface, the clean holds up far longer than a plain pressure rinse — typically 12 months or more on siding, and longer on roofs and shaded surfaces where we apply a post-treatment. Sun exposure, shade, sprinklers, and tree cover all affect exactly how fast growth returns.

Done the right way, yes. High-pressure cleaning is what damages roofs, not cleaning itself. We use the soft wash method — a cleaning solution applied at low pressure, left to dwell, then rinsed gently — which removes black streaks, algae, and moss without stripping granules or shortening the shingles' life. It's the method most shingle manufacturers specifically recommend.

Yes. Delta Softwash is fully licensed and insured, and we carry coverage for every job we run, residential or commercial. We're glad to provide a certificate of insurance for any property management company or HOA that requires one before scheduling.
