Siding Soft Wash Clears Heavy Green Buildup in Middlesex VT

This Middlesex home had a serious layer of green algae and grime working its way up the siding - especially heavy along the lower courses near the foundation. That kind of buildup doesn't just happen overnight. It creeps in slowly, and most homeowners don't notice how bad it's gotten until they're standing right next to it.

That green film you see on siding is almost always a mix of algae, mold, and mildew. It holds moisture against the surface, which over time can break down the material underneath - whether that's wood, vinyl, or fiber cement. Letting it sit isn't just a cosmetic issue. It's the kind of thing that quietly shortens the life of your exterior.

This is exactly where soft washing makes sense. Unlike high-pressure washing, soft washing uses a low-pressure application with a cleaning solution that actually kills the biological growth at the source. That means the grime doesn't just get knocked off - it gets treated. The result holds up a lot longer because you're not just rinsing the surface.

The before-and-after here is hard to miss. The lower siding and foundation wall came back clean and consistent across the entire side of the house. No streaking, no leftover patches. Just a clean, even finish that shows what the exterior is actually supposed to look like.

If your siding is starting to show that familiar green tint - especially on north-facing walls or anywhere that stays shaded and damp - it's worth getting it handled sooner rather than later. The longer that stuff sits, the harder it works against your home.
