Why choose Avenir Renovations?
Why renovate the exterior of your house in Leuven?
Protect the structure
A roof that lets water in, eroded brick joints, a crack that widens from one winter to the next: the envelope no longer protects what is behind it. Damage then appears inside, in the form of stains, mold, or peeling plaster.
A preventive renovation always costs less than a repair after damage.
Improve energy performance
Roof, walls, and joinery account for most of the heat loss in a house. Addressing them together allows for a real jump in EPC rating, useful for meeting Flemish renovation obligations or simply to reduce the bill.
A coherent envelope also avoids thermal bridges at joints, where separately done work often leaves cold spots.
Enhance the appearance of the house
A cleaned and re-jointed facade, a new roof, recent frames: the house changes its face from the street. In a Leuven market where many visit, the exterior condition sets the first impression.
Our exterior renovation solutions in Leuven
Four tasks, to be addressed alone or together, in a logical order.
The advantages of an exterior renovation with Avenir Renovations
Avenir Renovations coordinates your exterior work to optimize costs and ensure durability. Each intervention respects the constraints of the building and the Belgian climate.
We prioritize tasks, group what can be grouped, and avoid undoing one task to carry out another. The roof comes before the facade, the frames are installed before or during wall insulation, and the gutters are redone before the coatings.
This order is decided during the visit, even if you spread the work over several years.
Roof, floor frames, and facade completed in one go: the scaffolding is set up once, rented once. This is a real saving on a two or three-story house.
To give you an idea, the scaffolding for the front and back facade of a terraced house often amounts to thousands of euros. Setting it up just once also means fewer weeks of disruption for you, your neighbors, and the street.
Resistance to frost, driving rain, and urban pollution, limited maintenance, compatibility with the original brick. The tiles, mortars, and coatings are chosen to age with the house, not to impress on the day of the handover.
What is the price of an exterior renovation in Leuven?
The price depends on the selected items, surfaces, materials, and access. Price ranges including VAT, with the 6% VAT applicable to homes over ten years old.
| Type of work | Factors affecting the price | Indicative price including VAT |
| Roof renovation with insulation | Roofing material, insulation technique | 180 to 320 € / m² |
| Replacement of gutters and downpipes | Zinc or other material, length | 60 to 120 € / linear meter |
| Repointing and cleaning of facade | Condition of joints, cleaning technique | 60 to 120 € / m² |
| External facade insulation with finish | Thickness, coating, cladding or brick slips | 130 to 200 € / m² |
| Replacement of frames (3-bedroom house) | Material, glazing, number of openings | 10,000 to 22,000 € |
| Scaffolding for front and back facade (terraced house) | Height, rental duration, sidewalk | 2,500 to 6,000 € |
| Drainage and protection of foundations | Length, water connections | 80 to 200 € / linear meter |
The visit reviews the entire envelope, from the chimney to the foundation. Each element is priced separately, with a recommended order if you prefer to spread out the work.
Example: for a terraced house in Heverlee, an exterior renovation including insulated roof, new gutters, repointing of both facades, and replacement of frames often ranges between 35,000 and 65,000 euros including VAT, scaffolding included.
Procedures and grants for an exterior renovation in Leuven in 2026
A single file for multiple works
When an exterior renovation involves the roof, facade, and street-facing frames, it is better to combine all the tasks requiring permission into a single omgevingsvergunning application. This avoids partial refusals, accumulating delays, and inconsistencies between plans.
Identical works, such as re-jointing or tile replacement, are generally exempt and can start without waiting.
The grants by category
For owner-occupiers in income categories 3 and 4, Mijn VerbouwPremie supports the insulation of roofs and walls as well as glazing. Purely aesthetic works, such as facade cleaning, are not supported. All households benefit from the reduced VAT rate, provided the housing is over ten years old.
Neighbors and party walls
In a terraced house, the roof and facade connections are often made at the boundary with the neighbor, sometimes working from their side. A written agreement on access and any shared costs, for example for a common wall or gutter, should be prepared before the work begins.
Scaffolding and sidewalk
Scaffolding on the sidewalk requires a public space occupation permit from the City of Leuven. For a complete exterior renovation, it is requested for the entire duration of the work, with a margin for rainy days.
Neighbors, seasons, and duration: the organization of the site
Insulate without losing the appearance of the brick
The injection of the hollow wall, when it exists, does not change the appearance of the facade. Otherwise, some external insulation systems end with brick facing tiles that replicate the original look.
Informing the neighbors
For a semi-detached house, this is essential: the scaffolding, roof connections, and sometimes access from their side require it. A word before the work avoids many tensions, and we can help you prepare this contact.
The right season for outdoor work
From spring to early autumn for coatings, paints, and roofs. Frames and hollow wall injection can be done almost all year round.
A coating or paint applied in cold and humid weather dries poorly and ages faster: that is why we avoid scheduling them between November and March.
The duration of a complete exterior renovation
A complete exterior renovation of a semi-detached house generally takes four to eight weeks, scaffolding included. The timeline mainly depends on the roofing and the weather, with frames and repointing following quite quickly thereafter.
Frequently asked questions about exterior renovation in Leuven
How to choose the colors of the frames and facade?
We start from the existing brick or coating and the neighboring houses. Dark shades for the frames, such as anthracite, match most Leuven bricks. A sample placed on the facade, in daylight, always helps to make a decision.
What guarantees for roofing and facade work?
Work that affects stability and waterproofing is covered by the ten-year guarantee. The materials also benefit from the manufacturers' guarantees, often long for tiles, membranes, and frames. You will receive all the documents upon completion.
Can you live in the house during outdoor work?
Yes, in almost all cases. The rooms remain usable, only the installation of the frames requires clearing access to the windows for one day per room. Noise and dust are concentrated on demolition days.
Does an exterior renovation improve EPC classes?
Yes, if it includes insulation of the roof, walls, or replacement of frames. A cleaning or repointing alone, however, has no effect on the EPC certificate, even if they protect the house.
One site, one time
Combining roofing, frames, and facade means one scaffolding, one schedule, and connections made by the same team. The result is more durable and often cheaper than three separate sites.
