Facade water repellent
in Grez-Doiceau
On the building stock of Grez-Doiceau — brick and stone farmhouses, converted barns, contemporary houses with flat or low-pitched roofs — facade water repellent calls for an adapted method. Cleaning, then water-repellent impregnation of the brick or the render: water beads instead of soaking in, the facade dries and stays clean for longer.
BeforeAfter
The context in Grez-Doiceau
Why here in particular
What changes in Grez-Doiceau is the context: brick and stone farms, converted barns, contemporary houses with flat or low-pitched roofs. The big converted farm buildings combine long roof valleys, endless runs of fascia and old roof timbers that have rarely been treated.
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 Grez-Doiceau
The questions we get asked most often before this kind of job.
Does that solve a damp problem indoors?
If the damp comes from driving rain, largely yes. If it rises from the ground by capillary action, no: that is a different treatment and we say so.
And on a facade that is already painted?
The impregnation no longer penetrates. What you need then is a breathable mineral paint, not a water-repellent treatment.
Is scaffolding needed?
For two storeys, a platform or a mobile scaffold is often enough. That is costed separately and stated up front.
Do you come out to Grez-Doiceau with no extra call-out charge?
Yes. Grez-Doiceau 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.
