Why renovate your facade in Leuven?
A degraded facade is not just a matter of appearance. It protects everything behind it.
Protecting the walls from moisture
Sunken brick joints, peeling coating, cracks around openings: water eventually penetrates the masonry. The frost does the rest, widening microcracks from one winter to the next.
The signs of moisture that appear inside often originate from a facade that no longer fulfills its role. Acting in time always costs less than an emergency repair.
Improving the insulation of the house
A facade renovation can become an opportunity to insulate from the outside, without losing a centimeter of living space. For houses with cavity walls, which are very common in Kessel-Lo and Wilsele, injecting insulation from the facade is a quick alternative when the appearance of the brick must remain unchanged.
In both cases, the EPC label improves, and insulation work easily combines with repointing or cleaning done under the same scaffolding.
Giving the property a facelift
A clean and well-maintained facade changes the perception of a house from the street. In the center, the coated and painted facades of the 19th century regain their shine with careful repainting. Elsewhere, repointing and cleaning are often enough to rejuvenate a facade of several decades.

Our façade renovation solutions in Leuven
From simple cleaning to complete insulation, the solution depends on the substrate, its condition, and your goals.
The benefits of entrusting your facade to Avenir Renovations in Leuven
Entrusting your facade to Avenir Renovations in Leuven means benefiting from an accurate diagnosis and solutions tailored to the actual condition of your building. From substrate preparation to site security, each step is controlled to ensure a durable, well-maintained, and properly protected facade.
Nature of the substrate, condition of the joints, active or old cracks, moisture, heritage status of the building: everything is checked before proposing a solution.
You receive recommendations prioritized by urgency, indicating what is urgent and what can wait.
A well-renovated facade lasts fifteen to twenty years when the preparation is thorough. Sensitive points, window supports, corners, and joints between materials receive special attention.
Joinery, sidewalks, and surroundings are protected throughout the project.
Scaffolding, lift, or rope work depending on the facade configuration and street width. Safety nets limit dust and debris towards the sidewalk and neighbors.
Every evening, the site is tidied up and access to the house remains clear, even when the scaffolding occupies the entire width of the facade.
What is the price of a facade renovation in Leuven?
Type of intervention, surface area, condition of the substrate, and site access: these determine the budget. Price indications with reduced VAT at 6% (for homes over ten years old), excluding specific scaffolding.
| Type of work | Factors affecting the price | Indicative price including VAT |
| Cleaning and water-repellent treatment | Cleaning technique, condition of the brick | 20 to 40 € / m² |
| Repointing of brick facade | Depth of removal, type of mortar | 45 to 90 € / m² |
| Replacement of damaged bricks | Number of bricks, matching model search | 60 to 150 € / m² concerned |
| Rendering with plaster or cement | Necessary chiseling, type of render | 60 to 110 € / m² |
| Facade painting (preparation included) | Condition of the substrate, number of coats | 28 to 55 € / m² |
| External insulation with plaster or cladding | Thickness, finish, window frames | 130 to 200 € / m² |
| Injection of hollow walls | Width of the cavity, surface area | 20 to 35 € / m² |
On-site, the render is probed, wall moisture is measured, and joints are closely examined. The estimate is established after this analysis, with each item detailed, including scaffolding.
Example: for the street-facing facade of a city house in the center, approximately sixty square meters, gentle cleaning, complete repointing, and a water-repellent treatment often cost between 6,000 and 10,000 euros including VAT, scaffolding included.
Procedures and grants for facade renovation in Leuven in 2026
What requires a permit and what does not
A cleaning, repointing, or identical repainting is most often exempt from authorization. External insulation on the street side, a change of material or marked color modifies the appearance of the facade and generally requires an omgevingsvergunning.
The facades listed in the heritage inventory
In the historic center of Leuven, many facades are listed in the inventory of Flemish architectural heritage. For these buildings, shades, coatings, and techniques may be regulated. We check the status of the building and, if necessary, prepare the file with an architect.
The grant for insulating a facade
Mijn VerbouwPremie only supports a facade renovation if it includes insulation, either from the outside or by injecting cavity walls. Since March 2026, this grant is reserved for owner-occupiers in income categories 3 and 4. A simple cleaning or painting is not supported, but benefits from the reduced VAT rate once the dwelling has exceeded ten years.
The scaffolding on public roads
When the scaffolding or container occupies the sidewalk, a public domain occupation permit is required from the City of Leuven. In the narrow streets of the center, it may impose specific hours or signage. We submit it and integrate it into the planning.
Cleaning, a step not to rush
Why avoid high pressure on a façade
Improperly adjusted, a pressure washer can strip the facing and dig into the joints. We prefer low pressure, hydrogommage, or steam depending on the brick, with products suitable for moss and dirt.
Test before treating the entire façade
Always perform a test on a small, inconspicuous area. It allows you to check the reaction of the brick or coating and adjust the technique before applying it to the entire façade.
Frequently asked questions about façade renovation in Leuven
How often should a façade be renovated?
A well-pointed brick façade often lasts thirty to forty years before needing repointing. A coated or painted façade requires more frequent maintenance, generally every fifteen to twenty years, depending on exposure to rain.
Should a brick façade be waterproofed?
This is useful for a façade exposed to prevailing rains, often facing southwest in Belgium. The waterproofing must remain breathable: it prevents water from penetrating without blocking the moisture already present in the wall.
Can a street-facing façade in the center of Leuven be insulated?
This is possible, but rarely simple. External insulation alters the alignment and appearance of the façade, which requires permission and may be denied for a listed building. One often turns to injecting hollow walls or internal insulation.
How long does a façade renovation take?
For a terraced house, cleaning with repointing often takes one to two weeks, scaffolding included. External insulation typically requires three to five weeks, depending on the surface area and weather.
A renovated façade before the bad season
Façade work is ideally done from April to October, when coatings and paints dry under good conditions. Scaffolding should be booked several weeks in advance during the nice season.
To have a completed façade before winter, it is better to start the diagnosis now. It is free, and we will call you back within 48 hours.
