EIFS, stucco, painted concrete, and cladding cleaned at low pressure with a targeted solution instead of force. This is the correct method wherever pressure washing risks cracking or driving water into the envelope.
Confirm EIFS, stucco, painted concrete, or siding, since dilution ratio and dwell time vary by material.
Landscaping, signage, and hardscape are pre-wet and shielded before any solution is applied.
A diluted cleaning agent is applied at low pressure (typically under 500 psi) from the top of the elevation down.
The solution is left to break down organic growth for a set period before rinsing — no scrubbing or agitation on finish coats.
Surfaces are rinsed clean with low-pressure water, working top to bottom to avoid re-depositing residue.
Elevations are checked for missed staining, and landscaping is rinsed to limit solution exposure.
Shaded, north-facing, and tree-adjacent elevations in Metro Vancouver's damp climate regrow organic staining faster than sun-exposed walls, so frequency is often set by elevation rather than the whole building.
EIFS (exterior insulation and finish systems) has a thin coat over foam insulation, and standard stucco is porous. High pressure can crack the finish coat, drive water behind the cladding, or blow holes through EIFS entirely. Soft washing uses low pressure with a cleaning solution to do the work chemically instead of mechanically.
We use a diluted sodium hypochlorite or specialty algaecide solution matched to the substrate, applied at low pressure and rinsed. Landscaping, walkways, and adjacent surfaces are pre-wet and covered or shielded, and plants are rinsed after application to limit exposure.
It removes existing growth and kills the organism at the root, which is why it lasts longer than a pressure rinse alone. Regrowth timing depends on shade, moisture exposure, and orientation — north-facing and tree-shaded elevations typically need re-treatment sooner.
Yes. Painted tilt-up concrete, parkade exteriors, and coated precast all respond better to soft washing than pressure washing, which can etch or strip coatings prematurely.
Yes, the same access methods used for window cleaning — rope access, swing stage, or lift — carry the soft wash equipment and solution to height. It's often combined with a scheduled window cleaning visit to share access setup costs.

“Class act! Super easy to book and showed up on time and did a stellar job! I had all of the glass windows cleaned and let me tell you winter was unkind to all of our sliding glass doors and now they are perfection. Will be booking them again soon!”
“David and all of the team at Spiffy are good guys who aim to please. They did a wonderful job on my windows, gutters inside and out, and my deck glass which was covered in years of green algae. I didn't think I needed cleaning, but after it was done, I must say, I do enjoy my clear views.”
