Facade Techniques and Materials in Woluwe-Saint-Lambert

Exposed Brick Facade: Maintenance and Repointing

Brick is the dominant material of Woluwe facades. When well maintained, it can last indefinitely. However, lime mortar joints age, disintegrate due to freeze-thaw cycles, and allow water to enter. A complete repointing, which involves removing old joints to a depth of 2 to 3 cm and replacing them with suitable natural lime mortar, is necessary every 20 to 30 years to maintain the facade's waterproofing. The color of the joint is chosen to harmonize with the existing brick.

Lime Render: A Traditional Finish

Some Woluwe facades of pre-war houses or garden cities are covered with lime render. This breathable and durable material deserves to be preserved and restored rather than replaced with synthetic products. Repairing lime render requires specific expertise: preparing the substrate, applying in multiple layers according to traditional methods, and finishing with a trowel or brush. The results are durable and respectful of the original architecture.

External Thermal Insulation for Terraced Houses

External thermal insulation is particularly interesting for Woluwe terraced houses where the aim is to improve the energy performance score without reducing the living space. It involves gluing or anchoring insulating panels to the existing facade, followed by applying a finishing render or cladding. External thermal insulation eliminates thermal bridges in the facade and significantly improves comfort in both winter and summer. In Woluwe, its application is subject to urban planning regulations, including finishing color, allowable overhang, and permitted materials according to the zone.

Scaffolding: An Often Underestimated Item

For a two-story facade, scaffolding represents a significant portion of the total cost of a renovation, sometimes 20 to 30% of the budget. This is why it is often wise to combine facade and roofing work into a single project: a single scaffolding setup leads to substantial savings. For terraced houses with a front facade facing the street, scaffolding requires a road permit from the municipality. We manage these administrative procedures and anticipate processing times.

Deadlines and Seasonal Planning

Renovation work cannot be carried out during freezing weather. In Belgium, the optimal window for facade rendering and painting work extends from April to October, with particular attention to weather conditions. A complete renovation project for a terraced house facade generally lasts one to two weeks, including scaffolding. Planning the project early in the season helps avoid waiting times that often increase from June onward.
