Facade water repellent
in Lasne
Cleaning, then water-repellent impregnation of the brick or the render: water beads off instead of getting in, the facade dries and stays clean longer. In Lasne (1380) it is a regular request: detached properties add up plenty of roof square metres and outbuildings nobody thinks about until the first leak.
BeforeAfter
The context in Lasne
Why here in particular
Very scattered housing between meadows, hedges and woodland: Lasne is among the greenest municipalities in Walloon Brabant, with large isolated properties. In practice, those isolated properties add up a lot of square metres of roof plus outbuildings that get forgotten until the first leak.
A late-nineteenth-century Belgian brick literally drinks the driving rain from the west. The water passes through, comes out as saltpetre inside, and in winter it blows the surface apart.

How it runs
How the job runs
The same protocol everywhere, adapted to what the visit reveals on site. Nothing is decided from the pavement.
- Documented absorption test
- Low-pressure cleaning
- Anti-moss treatment
- Spot repointing
- Colourless water-repellent treatment with a beading effect
- Protection of window frames and surroundings
Diagnosis
Absorption test, condition of the joints, mapping the cracks.
Cleaning
Low pressure, plus anti-moss treatment where the facade is green.
Repairs
Repointing where the joints have eroded and treatment of the hairline cracks. A water repellent over an open joint is pointless.
Drying
48 to 72 h. That is the part we do not shorten.
Impregnation
Applied to saturation, from the bottom up, in two crossing passes.
Frequently asked questions
Facade water repellent in Lasne
The questions we get asked most often before this kind of job.
Is scaffolding needed?
For two storeys, a platform or a mobile scaffold is often enough. That is costed separately and stated up front.
Does the water-repellent treatment change the appearance?
A colourless product leaves the colour almost untouched, with a very slight deepening when wet. There is no glossy film.
Can the facade still breathe?
Yes, that is the whole point of an impregnation: it blocks liquid water and lets vapour through. A film-forming paint, by contrast, traps the damp inside.
Do you come out to Lasne with no extra call-out charge?
Yes. Lasne is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.

While we are on site
Combining two jobs in one visit brings the invoice down. We suggest it when it makes sense, never to pad the quote.
