Clean Siding Without the Risk of High Pressure.

Pressure washing vinyl siding, aluminum and soffit can force water behind panels, crack paint, break seals around windows and permanently damage surfaces. Soft washing gets the same result without any of that risk.

We apply a biodegradable cleaning solution at low pressure that penetrates and kills the biological growth causing the discolouration. Algae, mildew, mould and lichen treated at the source, not just rinsed off the surface.

We currently focus on vinyl siding, aluminum siding and soffit, keeping our scope tight so we can stand behind the results on every job.

Soft Washing vs. Pressure Washing

For siding and soffit, these are not interchangeable. Here is why it matters.

Pressure Washing

  • ✕High PSI can crack or warp vinyl panels
  • ✕Forces water behind siding into wall cavities
  • ✕Strips paint, caulk and window seals
  • ✕Blasts growth off the surface but does not kill the root
  • ✕Regrowth returns faster because spores remain

Soft Washing

  • ✓Low pressure, safe for all residential siding types
  • ✓No water forced behind panels or into walls
  • ✓Safe around windows, doors, caulk and paint
  • ✓Kills algae and mildew at the biological root
  • ✓Slower regrowth because the source is treated
What We Treat
Surfaces and Stains

Vinyl Siding

The most common siding type in KW. Soft washing removes algae, green staining and oxidation without risking panel damage.

Aluminum Siding

Older homes with aluminum siding need careful handling. Low pressure keeps panels intact while chemistry does the cleaning work.

Soffit and Fascia

Often overlooked but frequently discoloured. We treat soffit and fascia along with the siding for a consistent result across the whole roofline.

Algae and Green Staining

The green or black streaking on shaded north-facing walls is algae growth. Our solution kills it at the root so it does not come back in weeks.

Mildew and Mould

Mildew on siding is a surface problem, but left untreated it can work into seams and caulk. Treatment stops it before it becomes a bigger issue.

General Grime and Oxidation

Road dust, pollen and surface oxidation that builds up over years responds well to soft washing, restoring the original colour of your siding.

How We Do It
Our Process
01
Assess

We walk the exterior, identify stain types, check for gaps or damaged panels and confirm the right solution mix for your siding.

02
Protect

Plants, garden beds and hardscaping wetted and covered where needed. Windows and doors checked before application begins.

03
Apply

Biodegradable solution applied at low pressure, bottom to top. Dwell time allowed so the chemistry can work before rinsing.

04
Rinse

Gentle rinse from top to bottom. Results inspected section by section. Problem areas get a second application before we finish.

FAQ
Common Questions
Soft washing is an exterior cleaning method that uses low water pressure combined with a biodegradable cleaning solution to remove biological growth like algae, mildew and mould from siding and other surfaces. The pressure used is similar to a garden hose, so there is no risk of damage to panels, seals or paint.
Yes, with proper preparation. We thoroughly wet down plants, shrubs and garden beds before and after application to dilute any overspray or runoff. We use biodegradable solutions and avoid working on windy days where drift is a concern. Most landscaping handles the process without any issue.
Most homeowners see clean siding for two to four years before biological growth becomes noticeable again. Homes with heavy tree cover or north-facing walls that stay damp tend to see regrowth sooner. Annual or biannual maintenance washes are a cost-effective way to stay ahead of it.
Not at this time. We focus on siding, soffit and fascia to keep our scope tight and our results consistent. Roof soft washing involves different chemistry, different safety considerations and different equipment. We want to do a few things very well rather than everything at average quality.
We currently focus on vinyl and aluminum siding. If you have painted wood siding, brick or other surfaces, reach out and describe your situation. We will let you know honestly whether it is a good fit before booking.
No. We need access to the exterior of your home and a water source. As long as those are available, we can complete the job while you are out. We will let you know when we are done and flag anything worth your attention.

"The soft wash on our siding made the house look brand new. The green streaks on the north side had been there for years. Gone in one visit. Incredible difference."

"We had someone pressure wash our siding a few years ago and it cracked two panels. Gecko used soft wash and the results were just as good with zero damage. Should have done it this way the first time."

"Booked the soft wash along with window cleaning. Michael was on time, thorough and left the place looking sharp. The soffit cleaning was a nice touch, makes the whole roofline look consistent."
