    Brands the Gorilla Property Services network has worked with across Canada and the U.S.

    Your home’s exterior is what makes up its first impression to the outside world. Having build up of dirt and grime can quickly drive traffic away and can cause a significant drop in curb appeal. With so much riding on appearances, house washing is more important than ever. Sending the right message can help tenants and guests to feel at home, and encourage foot traffic for businesses, so don’t hesitate to call a Gorilla for your Calgary soft washing services.

    If you are noticing dirt and grime around your exterior, house washing processes are more complicated than you might think. Outdoor areas are often made up of a variety of construction materials, each of which have to be treated according to their unique characteristics. Power washing vulnerable areas can quickly lead to serious damage, but soft washing is exactly what the doctor ordered! Have a Gorilla swing into action, leaving your structures looking better than ever!

    Pressure Washing Vs. Soft Washing

    For many property owners, pressure washing seems like a magical cure-all for the outer areas of your home. While this might be true for more durable construction materials, such as fences, concrete, gazebos and driveways, it is not the right tool for stucco or vinyl siding. Unlike the highly pressurized sprays of traditional pressure washers, soft washing works using lower flow to dig deep into textures.

    A mobile pressure wash service can be applied in a variety of spaces, and they do have an instant impact. This method might work to provide a quick improvement, soft washing is known to leave heavily textured areas looking cleaner for up to seven times longer.

    The Soft Washing Process

    Instead of using high pressure sprays, soft washing takes a gentler approach. The materials around outdoor areas are chalk-full of cracks and crevices. These areas are prone to trapping and holding dirt, debris and creating spaces for growth to form. Moss, mold and mildew all latch onto surfaces, spreading and causing damage as they go. Softened materials can be blown to bits when pressures are too high, but at the right levels, water and cleaners drag out unwanted items, leaving a clean slate behind.

    Before any motor is fired up, a proper assessment is necessary for great results. Even low pressure sprays can damage aged or weakened materials. Our Gorillas make sure that treatments won’t cause unnecessary damage. Once safety precautions are in place – it is time to get to work! Eco-friendly cleansers and disinfecting sprays are used to loosen surface dirt that can then be sprayed away. Instead of settling for superficial results, our Gorillas dig deep for the cause of stains and discolourations, treating your issues completely.

    Common questions

    Softwashing — answered

    How long until I can stain after soft washing?

    Allow 48 to 72 hours of drying before staining after a soft wash, the same window as painting. Stain needs to soak into dry wood to bond properly, so trapped moisture will ruin the finish. Warm, dry weather helps; humidity slows things down.

    How is soft washing different on painted surfaces?

    The risk with painted surfaces is using chemistry strong enough to lift the coating along with the grime. We dilute specifically to avoid that. The chemistry targets algae and mildew, not the paint film, and low pressure means no blasting under the edges where peeling usually starts.

    What chemicals do you use in soft washing?

    Sodium hypochlorite, the active ingredient in household bleach, at a controlled dilution, combined with surfactants that help it cling to the surface. This is the industry-standard soft-wash chemistry, mixed to a concentration that kills biological growth while staying gentle on the material being cleaned.

    Can soft washing clean exterior columns?

    Columns are exactly where gentle cleaning matters. Painted wood and decorative detailing can’t take aggressive pressure without risking the finish, so soft washing is the right call. The chemistry clears biological growth from grooves and capitals while keeping the paint and profile intact.

    Can soft washing be done on a townhouse?

    Yes. We provide coordinated soft washing for townhouse complexes, typically scheduled through strata or HOA management so every unit is treated consistently. Low-pressure chemistry clears algae and mildew from shared siding and roofs without the risk pressure washing poses to attached units.

    Do you offer recurring service?

    Yes, recurring soft-wash plans are popular with Calgary customers. On an annual or biennial schedule, you get locked-in pricing and priority booking, and your exterior stays ahead of algae and mould instead of letting it rebuild between cleanings.

    Do you serve marinas?

    Yes, we clean marina exteriors and the buildings adjacent to them. Because the work sits over or beside the water, our crews sometimes use marine-friendly chemistry to keep runoff appropriate for the setting while still clearing algae and biological staining from the structures.

    Does soft washing remove biological growth from concrete?

    People assume concrete is tough enough for pressure, but high PSI etches the surface and leaves striping that traps dirt and regrows algae faster. Soft washing takes a gentler route, killing the growth chemically and rinsing it away, which keeps the concrete cleaner for longer.

    Why does soft wash use lower pressure?

    In Calgary, low pressure delivers chemistry without damaging surfaces. High pressure can score siding, splinter cedar, and pit stucco, so our crews let the chemistry kill algae and mildew at the root while pressure only rinses gently.
