"How often should I have my house washed?" is the single most common question we get. The honest answer: it depends on what's around your home — but most properties in Kentuckiana benefit from at least one professional cleaning every year.
House siding
Once a year is the sweet spot for most homes. If you have heavy tree cover, north-facing walls or are near the river, you may notice green algae returning faster — bumping to a yearly soft wash keeps it from ever getting bad.
Concrete driveways & sidewalks
Plan on every 12–18 months. Tire marks, oil drips and organic stains build up quickly, especially in shaded driveways.
Decks & fences
Wood needs a gentle clean every 1–2 years to remove the gray oxidation layer and keep the stain looking fresh. Skipping this leads to splintering and early replacement.
Roofs
Those black streaks aren't dirt — they're Gloeocapsa magma, a roof-eating algae. A soft wash every 3–5 years protects your shingles and can extend roof life by years.
Quick rule of thumb
If you can see green, black streaks or chalky buildup from the curb — it's time.
