Port Huron House Wash Clears Years of Algae and Rust

This Port Huron home had a pretty common situation - years of algae streaking across the siding and rust stains working their way up from the base of the house. The kind of buildup that happens gradually, so you almost don't notice it until one day you're standing in the backyard and it just hits you. The siding was covered in dark green streaking, especially up toward the gable, and there were orange-brown rust stains bleeding onto the lower panels near a pipe fitting along the foundation.

We used a soft wash approach for the full exterior. Soft washing isn't just a gentle rinse - it uses a low-pressure application with professional-grade cleaning solutions that actually kill the algae, mold, and bacteria living in the siding rather than just blasting the surface. High pressure might knock some of it loose, but it won't kill the root of the problem. Soft washing does. It's also a lot safer for vinyl siding, windows, and trim than running high pressure over everything.

The rust stains required a separate treatment. Rust doesn't respond to the same cleaners used for biological growth - it needs a dedicated rust remover applied directly to the affected area. Those orange stains along the lower siding came out clean, and the difference between the before and after on that section alone is pretty striking.

What you end up with after a full house wash and rust removal is more than just a cleaner look. You're stopping the algae from continuing to eat into the surface, and you're getting rid of staining that regular washing just won't touch. The siding on this home looks uniform and bright again - no streaking, no discoloration, no rust bleeding down from the fixtures.

Homes in this area deal with algae growth and rust staining on a regular basis. It's not a reflection of how well you maintain your property - it's just what happens over time with moisture, shade, and metal hardware. The good news is it's completely fixable, usually in a single visit.
