Building exterior washing

Buildings go green on the north side and grey everywhere else, and it happens so slowly that nobody notices until a photo gets taken. We wash commercial exteriors across the province, including high rise.

Soft wash where soft wash is what the surface needs

Not every surface wants full pressure. Cladding, painted steel, stucco and older wood can all be damaged by someone treating them like a concrete pad. The right answer is usually lower pressure and the right product, letting the cleaner do the work instead of forcing it with a nozzle. We read the surface first and we have been doing it since 1997.

What we clean on a building

  • Vinyl, aluminum and steel siding, including the green that sets in on shaded walls
  • Cladding and panel systems on commercial and institutional buildings
  • High rise exteriors
  • Soffit, fascia and trim
  • Concrete, block and masonry walls

The green is not dirt

That grey green film on a north facing wall is biological. It is algae, and in our climate it is basically guaranteed, because we have damp air and long stretches without direct sun on that side of a building. Blasting it off with pressure alone knocks the surface layer down and leaves the rest to come straight back. Treating it properly is what makes a wash last.

Property managers and repeat work

Most building work we do is on a cycle, because exteriors do not stay clean and everybody would rather book it than think about it. If you look after several buildings, it is worth walking us through all of them at once so we can tell you which ones actually need doing this year and which can wait.

Questions we get

Do you wash high rise buildings?
Yes, high rise exteriors are part of what we do. Tell us the building and the access situation and we will tell you how we would approach it.
What is soft washing and do I need it?
Soft washing means using lower pressure and the right cleaning product instead of relying on force. It is what you want on siding, cladding, painted surfaces and older wood, where high pressure can drive water behind the surface or damage the finish. Hard surfaces like concrete can usually take more.
Will the cleaning products hurt the landscaping?
No. We use environmentally safe products that will not harm plants, grass or animals. That matters on a building wash because the beds and the lawn are directly under everything we are cleaning.
How often should a commercial building be washed?
It depends on the exposure more than the calendar. A shaded north wall under trees goes green far faster than a south facing wall in the open. If you tell us what the building looks like now we can tell you what a sensible cycle looks like for it.
