Homeowners and businesses alike trust WashTech for dependable service, year after year.
Our house washing service uses a specialized soft washing technique to gently clean your home’s exterior without causing surface damage. This low-pressure method combines biodegradable detergents with precision rinsing to eliminate organic buildup like algae, moss, mold, and mildew- especially from delicate materials such as stucco, wood, Hardie board, and vinyl.
A gentler alternative designed for building exteriors.
While pressure washing blasts surfaces with high force, soft washing uses low-pressure + specially formulated cleaners to safely treat and remove organic buildup. This reduces the risk of damage, moisture intrusion, or surface erosion- especially on delicate materials like roofing, vinyl siding, wood trim, and painted finishes.
