If your home, strata or commercial space needs a bit of sprucing up but you aren’t sure where to start, just call a Gorilla! Our Markham soft washing services can take years off of your structures without the threat of damage or a subpar result.

    Understanding the Soft Wash Process

    For many property owners, the idea of “soft washing” is a new one. In the past, professional pressure washing services have been a magical cure-all for stains and discolourations around outdoor spaces. Pressure washers have been used for roof cleaning, gutter cleaning and even window cleaning. High pressure and a heavy hand might seem like the best way to tackle stubborn stains but this is not the case. Too much pressure might be able to treat some surface stains but treating the cause is more important than the symptom. In fact, power washing can do more harm than good. Delicate, aged or weakened materials can be blown away, leaving cracks, bald spots or even water damage.

    The advantage of low pressure sprays is that water works with its surroundings and textures instead of against it. Low pressure cleaning allows water to travel into cracks, crevices and openings around exterior walls or roofing. When combined with cleansing agents, this process leads to a deep-down clean that can last up to seven times longer than any surface treatment.

    Seeking Out Professional Care

    It is easy enough to borrow or rent power tools but proper results mean more than flipping a power switch. One wrong move can mean damage to your property, along with costly repair bills. Calling in a professional for your exterior cleaning services mean the best results in the safest way possible. Our Gorillas use eco-friendly cleaning methods, as well as securing any nearby waterways or inlets from contamination. Cleaners are applied to loosen surface dirt and are scrubbed with specialty brushes. Only then are high quality soft washers fired up!

    Common questions

    Softwashing — answered

    Can you soft wash my vinyl siding?

    In Markham, vinyl siding soft washing is standard work for our crews. It is the surface we treat most often. Low pressure and chemistry handle the algae and biological staining that vinyl collects, cleaning the panels effectively without the warping risk of high pressure.

    Does soft washing remove algae?

    Yes, algae is the primary target of soft washing, including the black streaks it leaves on roofs and walls. The biodegradable chemistry kills the growth at the root rather than just rinsing the surface, which is why a soft-washed surface stays clean far longer than a pressure-rinsed one.

    Is soft washing chemistry safe?

    Yes, when used at controlled dilution with proper pre-rinse and post-rinse protocols. The chemistry is biodegradable and breaks down into inert components within days of application. The safety lies in the dilution and rinsing, which keep it effective on growth yet gentle on surroundings.

    How often should I soft wash my home?

    Most homes need soft washing every four to six years. Properties under heavy tree canopy, in damp climates, or sitting in chronic shade hold moisture longer and grow algae faster, so they often land on the shorter end of that range or sooner.

    Will my kids be safe?

    For Markham families, our standard protocol keeps children indoors while crews work. It keeps them away from wet surfaces, ladders, and equipment during the job. Once the treated areas dry, generally within one to two hours, they are safe for kids.

    Do you do a final inspection?

    Yes, every job ends with a visual inspection after the final rinse to confirm the cleaning is complete and even. We then walk the property with you at completion, so you can see the results firsthand and point out anything you want a closer look at.

    Can you soft wash my pool deck?

    A pool deck is one place where algae is a safety issue, not just a cosmetic one, since growth on wet concrete gets dangerously slick. Soft washing kills that growth at the root, and our crews protect the pool water from the chemistry while they work.

    Does soft washing remove black streaks?

    Those black streaks are not dirt, so scrubbing or rinsing them does nothing. They are colonies of Gloeocapsa magma algae feeding on the shingles, which is why only chemistry removes them. Soft washing kills the algae at the source and the staining washes away with it.

    Can soft washing damage my home?

    Properly applied, no. Soft washing is designed to protect surfaces, not harm them. The combination of low pressure, well below 500 PSI, and appropriately diluted chemistry is gentle on every common residential exterior material, from vinyl and painted wood to stucco and asphalt roofing.
