Siding & Exterior Walls

Protect Your Home’s Envelope with a Professional Wash 

Your siding is your home’s first line of defense, but it’s also one of the largest surfaces to keep clean. Over time, dust, pollution, and spider webs accumulate on your walls. In Vancouver and Surrey, the most common issue is “green staining” on the side of the house that stays in the shade. This is typically a mix of algae and mildew that thrives in our damp environment. At Onsite, we provide expert siding power washing Surrey that removes these contaminants, protecting your home’s “envelope” and restoring its original color. 

Many homeowners are nervous about power washing their siding, and for good reason. High pressure can force water behind the siding panels, leading to mold inside the walls or even cracking vinyl and stucco. That is why we utilize a “soft wash” system for exterior wall cleaning Vancouver. This method relies on specialized cleaning solutions and low pressure to gently lift away grime without risking the structural integrity of your home. 

Cleaning All Surface Types 

Every home is built differently, and we tailor our approach to your specific siding material: 

• Vinyl Siding: We remove the chalky “oxidation” and green algae that often plague vinyl, leaving a streak-free finish. 
• Stucco & Hardie Plank: These textured surfaces love to hold onto dust and dirt. Our stucco cleaning BC uses the perfect pressure to deep-clean the “nooks and crannies” without chipping the finish. 
• Brick & Stone: We blast away the “white fuzz” (efflorescence) and moss that can grow in the mortar joints, restoring the classic look of your masonry. 
• Metal Siding: We use gentle cleaners to remove road salt and pollution, ensuring your metal exterior remains bright and rust-free.
