Vermont winters are rough on a home's exterior. By the time the cold breaks, most siding is carrying a full season's worth of algae, mold, and grime - especially along the lower courses where moisture lingers. That green-black buildup you see creeping across the siding isn't just an eyesore. Left alone, it eats into the surface and shortens the life of your siding faster than most homeowners realize.
This is what we were working with on a couple of Colchester homes - heavy algae streaking across vinyl siding from top to bottom, concentrated along the panel seams and near the foundation line where it gets the least sun. The kind of buildup that makes a house look years older than it is. Standard pressure washing isn't the right call here. Too much pressure on vinyl siding can crack panels, force water behind the siding, and cause real damage. That's why we use soft washing - low pressure combined with professional-grade cleaning solution that actually kills the algae and mold at the root instead of just blasting the surface.
The results speak for themselves. Clean, bright siding with zero streaking and no damage to the panels or trim. We also handled some concrete steps that were covered in algae growth and porch railings that had gone dingy and gray - soft washing works just as well on those surfaces, and it's safe for the surrounding landscaping when applied correctly. Every inch gets treated the same way, whether it's the siding up high or the hard-to-reach spots where a roof line meets the wall.
That's the thing about house washing done right - it's not just about making the front look good for a photo. It's a full exterior clean that protects your investment. Algae and mold are living organisms. They spread. Cleaning them off regularly keeps your siding in better shape longer, which puts off costly repairs or replacement. One good soft wash can make a house look like it just got a fresh coat of paint - without the price tag.
House washing season is officially back for us here in Vermont, and we're already booking jobs across Colchester and the surrounding area. If your siding is looking like these before shots, it's a good time to get it taken care of before the growth gets any worse heading into the warmer months.
