Wall & Facade Cleaning In Meerhout
Is the north side of your house slowly going green?
Cleaning for brick facades, render and garden walls, using a method suited to the brick, the pointing and the state of the wall
Walls rarely get dirty overnight. It starts as a green film on the side the sun never reaches, below a gutter that sometimes overflows or behind a tree growing close to the house. Dark streaks run down from the window sills, and white render slowly turns grey. In the wooded Kempen, with plenty of shade and damp around houses, that growth gets going faster than on an open street. When we clean walls and facades in Meerhout, we look at the wall itself first: soft or hard brick, sound or weathered pointing, brick or render. Only then do we choose the pressure and the method.

What to expect
Wall and facade cleaning in Meerhout that spares brick and pointing
You can't clean a house wall the way you'd clean a patio. Water driven hard at brick looks for a way in. Here's what we watch for.
Green and black lifted off
Algae, moss and the black staining from an overflowing gutter come away, and your yellow or red brick shows its real colour again. On a badly affected wall we use a treatment against green growth where it's needed, keeping an eye on the plants at the foot of the wall.
Pointing checked first
Weathered or loose pointing washes out further under a hard jet. If we spot that, we tell you before we start, and either clean those areas very gently or suggest getting them repointed first.
Low pressure on brick and render
High pressure is for hard materials. On facing brick, and especially on render, we keep the pressure low and stand further back, so the surface stays intact and no water gets forced in behind the brick.
Bluestone and windows protected
Bluestone window sills and thresholds can't take acid, so no acidic product goes near them. Windows, frames and air vents are covered before we start.
Garden walls too
A garden wall takes the weather on both faces and often has a coping that moss clings to. We clean both sides and the top with the same care we'd give your house.
Protection if you want it
After cleaning, you can have the wall treated with a water-repellent impregnation. A good one keeps rain on the outside without sealing the wall in, so growth has less to hold on to. It isn't right for every wall, so we talk it through first.
Brick and render
Why some walls can take water and others can't
A hard facing brick with good pointing can handle a decent rinse. A softer, older brick or a coat of render can't: too much pressure wears the outside away and leaves a rough surface that gets dirty again sooner. So we always start with a test area somewhere discreet, behind a shrub or next to the downpipe. We work from the top down, so dirty water never runs over a section that's already clean, and rinse thoroughly as we go. Bluestone window sills, which you'll find on plenty of Flemish houses, get water and a gentle approach only.
- Test area somewhere out of sight
- Pressure matched to brick, pointing or render
- Cleaned from the top down
- Windows, frames and vents covered
- Water-repellent impregnation as an option
Our approach
From first photo to a clean facade
Wall cleaning needs a dry spell without frost, so we plan the date together with you.
- 01
A look at the wall
A few photos of the facade or garden wall, including some close-ups, already give us a good idea. We'll also ask whether anything has ever been applied to the wall, such as paint or an earlier impregnation.
- 02
Pointing and test area
When we visit we check the pointing and the condition of the brick, and clean a small area. You see the result straight away, and we know how much pressure the wall will take.
- 03
Covering up
Windows, doors, air vents, outside lights and the plants at the foot of the wall are covered. For the patio or drive below the wall, we decide in advance which way the rinse water should drain.
- 04
Top to bottom
We work in strips from the roofline down to the plinth and rinse each one. Stubborn green patches get a treatment that's left to work for a while where needed.
- 05
Final check and optional impregnation
Once the wall has dried we walk round the house with you. If you'd like an impregnation, it only goes on when the brick has fully dried out.

Questions
Wall and facade cleaning in Meerhout: your questions
Isn't a pressure washer bad for brickwork?
At the wrong pressure, yes. A hard jet on soft brick, render or weak pointing damages the surface and can push water in behind the brick. That's why we use low pressure on walls, choose the method wall by wall and test first.
Can you clean rendered walls?
Yes, with even more care than brick. Render has a thin finishing coat that's easy to blast off. We use very low pressure and, where needed, a product that loosens the growth so less force is required. If the render already has cracks or loose patches, we'll point those out first.
My pointing is in poor shape. What then?
Then we'd usually suggest having it repointed first and cleaned afterwards. Water on weathered mortar washes more of it out and can let damp into the wall. We'll tell you plainly what we see, even if it means the cleaning is better left for now.
How soon will the wall go green again?
On a sunny south-facing wall it takes a long time. A north wall shaded by trees, or one below a gutter that overflows, can get a green film again within a few years. A clean, working gutter and some pruning around the house make a big difference, as does an impregnation on walls that suit one.
Do you clean garden walls and low walls around the patio?
Certainly. Garden walls, brick planters and low walls along the drive are handled the same way as a facade. Because they're exposed on every side, the top is often the dirtiest part, so it gets extra attention.
