How Much Water Does It Take to Soft Wash a House?

One of the most common questions we hear at Bayside Clean is, "How much water is used washing my house”?

Many homeowners assume that exterior cleaning requires thousands of litres of water, but the reality is quite the opposite. Soft washing is one of the most effective and water-efficient ways to clean your home's exterior.

We're mindful of water usage throughout every job. We never let hoses run unnecessarily, and our equipment is designed to recirculate water whenever the trigger isn't engaged, eliminating needless waste. Most importantly, soft washing doesn't rely on high pressure and excessive water to get results. Instead, we use professional-grade soaps and detergents that break down algae, mildew, dirt, and organic buildup at the source, allowing the cleaning solution to do the heavy lifting—not thousands of gallons of water.

Soft Washing Uses Less Water Than You Think

For a typical 1,500-2000 square-foot home, a professional soft wash system generally uses between (250-350 gallons) from start to finish. This includes both the cleaning solution application and the final rinse.

The majority of water used during a house wash isn't in the cleaning process —it's in the rinse process. Even at the higher end, that's often less water than many homeowners use watering their lawn over the course of a day.

A typical Soft Wash may use:

5-10 gallons of cleaning detergent
250-350 gallons for washing and rinsing

Why Soft Washing Is More Effective Than Pressure Washing

Soft washing doesn't just remove visible dirt. It targets the root cause of staining, including:

Algae
Pollen
Mold and Mildew
Lichen & Moss
Spider Webs, Bird Droppings

This means surfaces stay cleaner longer while avoiding the risk of damage that excessive pressure can cause to siding, soffits, fascia, gutters, and painted surfaces.
