Why Is My Siding Turning Green

If you notice a green tint creeping across your home exterior, you are seeing the result of the Fraser Valley damp climate. Our consistent rainfall and shaded residential areas create the perfect environment for algae and moss to thrive on siding materials. This buildup is not just an aesthetic issue, as it traps moisture against your walls, which can lead to wood rot, premature paint failure, and dangerous mold growth hidden behind the panels. Addressing these organic invaders early is essential to maintaining the structural integrity of your property.

The most effective way to eliminate this growth is through a professional soft wash treatment. Unlike standard power washing, which uses high pressure that can force water behind siding and cause hidden internal damage, soft washing utilizes low pressure combined with specialized eco-friendly solutions. This method is superior because it kills the algae and mold spores at the root rather than just blasting the surface clean. Relying on high-pressure equipment often fails to neutralize the growth entirely, leading to recurring stains within just a few months.

A professional soft wash treats the organic growth, rinses away the discoloration gently, and leaves behind a protective barrier that helps prevent regrowth for many months. By scheduling a treatment before the accumulation spreads further or begins holding significant moisture against your walls, you protect your investment from long-term decay. Taking this proactive step ensures your home remains clean, safe, and curb-appeal ready throughout our rainy seasons.
