That green, streaky buildup you see on siding is not just dirt. It is algae, mildew, and biological growth - and it spreads. Left alone, it works its way into the surface of your siding and starts to break it down over time. Most homeowners do not realize how bad it has gotten until they see it side by side with a clean wall.
That is exactly what we were dealing with on this Rumson home. The siding had heavy green algae coverage running top to bottom, with dark streaking around the windows and corners. It was one of those situations where the house just looked tired - even though the structure itself was in great shape.
We used soft washing to take care of it. Here is why that matters - soft washing uses low pressure combined with a professional-grade cleaning solution that kills the biological growth at the source. It does not blast the siding with high pressure and risk cracking panels, blowing out caulk, or forcing water behind the walls. It cleans it properly and keeps the siding intact.
The result is exactly what you want. Bright, uniform siding with no streaks, no green tint, and no residue. The whole exterior looks fresh without a single panel being damaged in the process. That is the difference between doing it fast and doing it right.
Soft washing is hands down the safest and most effective method for cleaning vinyl and fiber cement siding. If your home has that same dull, green-tinged look, it is not something you want to keep ignoring - because the longer it sits, the harder it is to reverse.
