We remove algae, pollution, efflorescence and graffiti from brick, render, natural stone and cladding. We match the pressure to the material, because spraying too hard opens the joints and damages the stone.
On the shaded side moisture lingers, and that is where algae and moss take hold. Left alone it eats into the pointing. On delicate facades we use low pressure and softwash rather than force, so the stone stays intact.

White bloom on masonry is a different story from green or black dirt when it comes to facade cleaning in Delft. That white haze consists of salts that moisture brings out of the brick or mortar, which crystallise at the surface. Spray water on it and you dissolve them and draw part of them back into the brick, after which they simply reappear as it dries.
With salt bloom we do the opposite of what you would expect: brush it dry first, so the crystals fall off the wall instead of dissolving into it. Whatever is still visible afterwards gets a product intended for bloom and a sparing rinse. The rest of the facade is cleaned in the way that suits the masonry.
The professional is insured and vetted and brings dry brushes for the bloom alongside his rinsing equipment. The products are eco-friendly and safe for children, pets and the garden plants along the wall. You have the same professional for the job and for any follow-up visit.
