Algae on Siding

What’s on my siding?

After all of our experience, we’ll say about 90% of our house washing services are to address green algae growth.

Siding is also filthy! Have you looked at an old photo of your home recently? Various soiling accumulates over time. Also, homes with good airflow develop a static charge. As particulates in the wind blow by, filth is attracted like a magnet.

But, wait..?there’s more! Tree sugars, pollen and other small sticky by-products of plants not only contribute to holding dirt on your siding but by providing nourishment for explosive growth rates.

House Weeds

Cleaning algae from your siding is like pulling weeds in the yard. If you leave the roots, the plant returns much quicker. Lead Dog’s house washing service disinfects biological growth to a decayed brown color. If its green, the roots are still there!

Lead Dog’s Process

Our low pressure system gently applies a solution consisting of a disinfectant, soap and a sticky surfactant. The surfactant makes the solution sticky so it clings to your siding without pouring down. Lead Dog’s solution dwells to disinfect growth and release contaminants for an extended period of time. Finally, the surface is rinsed.
