Standard pressure washing uses high-pressure water to blast grime off hard surfaces like concrete, brick, and stone.
Most residential cleaning jobs range from $150 to $950 depending on the size of the home and scope of work. Driveway cleaning starts around $150, while full house and roof wash packages depend on total square footage. We provide 100% free, no-obligation quotes.
Absolutely not. We use biodegradable, eco-friendly, plant-safe and pet-safe solutions. We pre-wet and post-rinse all surrounding vegetation during our washing process to ensure your plants, grass, and shrubs remain healthy and protected.
In the Pacific Northwest climate, we recommend having your siding washed once a year and your concrete cleaned annually to prevent slippery algae buildup. Roof treatments are typically needed every 2 to 3 years to prevent moss and lichen from damaging shingles.
