ServiceMaster uses a wide variety of methods to tackle building façade cleaning. One of the many tools at our disposal is known as soft washing. Soft Washing is a cleaning method that combines low pressure water, pumps and chemical cleaners to gently clean a building’s exterior.


We use environmentally friendly cleaning solutions to remove a variety of organic growth from the building’s exterior. During soft washing, we hand spray cleaning solutions on areas and allow them to react with debris. Once the cleaning product has finished reacting, we wash it off using water. Sometimes we also use soft brushes to help remove any organic material.


A key part of the soft washing process is the selection of the right solution for the job. Our teams carefully select products that will have the least amount of environmental impact. We often add an organic-growth retarding treatment to the surface to reduce the need for a follow-up cleaning.


Soft washing is very different from power washing. Soft Washing does not use high pressure water streams that can enter a buildings envelope during cleaning. Because of this it is less likely to do mechanical damage or promote rot. Many professional associations recommend Soft Washing because it is very effective at removing organic matter such as mildew, moss and algae. Upper floors can be cleaned with the help of tucker poles to clean off the areas effectively.

Roof Cleaning – Treatment

Throughout the Lower Mainland, we frequently use soft washing for roof cleaning. Organic material, such as moss, can easily stick to roofs because most roofs tend to have a rough, pitted, surface. The goal during roof washing is to kill only the organic material on the roof and not to damage the roof system or surrounding flora. During roof cleaning, the soft wash solutions that we use tends to require a greater dwell time and often require additional agitation with a soft brush for the best outcome.


Crews cleaning roofs require additional training and fall protection equipment to ensure they remain safe while roof cleaning. Workers also need to have the right footwear and awareness to ensure they do not damage a roof surface or vents, skylights and chimneys.

At ServiceMaster Clean, we’re highly aware of these challenges, and bring our technical knowledge to each job we service.

Eyebrow Cleaning

Soft washing Vancouver Building Facade cleaningBuilding eyebrows are the areas at the base of verandas, decks and other features. When it comes to building cleaning, eyebrows are often overlooked, because they cause fewer potential problems in terms of building maintenance. Cleaning a buildings eyebrows is important to the overall look of a building because the eyebrows are also one of a buildings most visible features.


Eyebrow cleaning should usually be done at the same time as building façade cleaning or window cleaning. This will improve efficiencies as crews can clean all three at once, and keep the building’s appearance uniform.

Balcony & Patio Cleaning

Despite the best efforts of residents to keep balconies and patios clean, discolouration and stains will eventually occur due to normal use. Often, these stains cannot be removed through regular cleaning methods and they will require more aggressive techniques, such as power washing, soft washing and hand scrubbing.


If everybody cleaned their own balconies with these methods at different times, it would be disruptive to other residents. To ensures that any runoff from the balcony washing is properly managed, cleaned up and does not affect the appearance of units below, it is recommended that stratas to periodically organize these cleanings for all residents.
