Why renovate your home in Woluwe-Saint-Lambert?
A building from the 60s to 90s in need of upgrading
A large part of the residential stock in Woluwe dates from the 60s to 90s. These houses are well-built but have reached a stage where several aspects require intervention: thermal insulation is often non-existent or insufficient, electrical installations no longer meet current standards, and original joinery (old single or double glazing) lets in cold and noise. Addressing these elements immediately improves comfort and reduces energy consumption in the long term.
Adapting the space to today's living
Houses from the 70s and 80s were designed with a rigid layout: closed living rooms, partitioned kitchens, separate bedrooms. Today, uses have changed. Opening up living spaces, creating a home office, or adding an additional bathroom are common transformations. They are carried out to measure, respecting load-bearing walls and the building's technical constraints.
Enhancing a property in a premium market
Woluwe-Saint-Lambert is one of the most sought-after municipalities in Brussels. A renovated property (insulation, frames, bathroom, kitchen) stands out clearly in the market. It is an investment that appreciates, both in use and resale. For owners considering renting, targeted renovation also significantly improves rental yield.
Progress of a renovation project
Each renovation follows a logical sequence, from the first visit to the handover. Here’s how we organize the project:
Our renovation solutions in Woluwe-Saint-Lambert
Depending on the condition of the property and your priorities, we offer several levels of intervention:
- Partial or staged renovation: floors, painting, without touching the structure
- Complete interior renovation: room redistribution, new networks, finishes from A to Z
- Energy renovation: insulation, frames, heating, ventilation, with support for available grants in the Brussels region
- Structural renovation: demolition of load-bearing walls, creation of openings, consolidation
For the renovation of each space, we have specialized teams: bedroom, bathroom, kitchen and living room.

Essential Technical Points in Woluwean Buildings
Electrical Networks: Compliance Often Necessary
In Woluwean houses built between 1960 and 1990, electrical installations have often not evolved since their installation. The absence of a 30 mA differential per circuit, outdated distribution boards, and aluminum wiring in some older homes pose compliance and safety issues. Electrical compliance is generally the first technical project to plan before any broader renovation: it conditions the new lighting networks, the bathroom, the kitchen, and sometimes access to Brussels renovation grants.
Moisture and Foundations: Diagnose Before Starting
In areas close to the Woluwe Valley, some foundations are exposed to rising damp or lateral infiltrations. Renovating the floors and walls of a basement or ground floor without first addressing the cause of moisture leads to rapid deterioration: mold, peeling, warping. Our preliminary diagnosis systematically includes a check of the masonry, with concrete recommendations on the treatments to implement before the finishes.
Acoustics Between Adjacent Homes
Terraced houses share one or two walls with neighbors. Impact noise, voices, plumbing: these nuisances are common in Woluwean buildings from the 70s. Renovation is the right time to address these issues at a lower cost: sound insulation of floors between levels, acoustic lining of the party wall, sealing of duct passages. These interventions naturally integrate into a comprehensive project without additional mobilization costs.
Phasing of Work: A Logic to Respect
The order of interventions is not neutral. The logical sequence in a Woluwean renovation is as follows: structural work and moisture treatment first, then technical networks (electricity, plumbing, ventilation), followed by insulation and joinery, and finally finishes. Reversing this order often requires redoing work or damaging new finishes. We establish this phasing from the estimation phase so that you can prioritize without waste, whether you do everything at once or in stages over several years.
Ventilation: Don't Forget Air Renewal
Houses from the 70s-80s were not designed to be airtight. When insulation is improved and frames are replaced, indoor air quality can deteriorate if ventilation does not keep up. Installing a mechanical ventilation system (single flow with humidity control or double flow with heat recovery) is recommended in any renovation that involves insulation or joinery. In the Brussels Region, a double flow mechanical ventilation system is often eligible for energy grants and directly improves the energy performance score.
