Facade renovation and painting
We breathe new life into your facade:

- the installation or repair of gutters and cornices,
- roof insulation from the inside or outside.
All work is carried out by qualified and experienced craftsmen.
Outdoor fit-outs
We create your surroundings:
- terraces (wood, tiles, stone),
- driveways, paving, fences, and walls,
- draining or vehicle-accessible floor coverings.
These works harmoniously complement the renovation of your envelope.

FAQ – Exterior renovation in Brussels
Do I need a building permit to redo my facade?
Not always. A simple repainting to the same specifications does not require it. However, external insulation or changing the appearance may require a declaration or a permit. We will check this with you.
Can I benefit from multiple grants?
Yes, provided you have completed a housing audit beforehand. You can combine grants for insulation, frames, ventilation... The amount can cover a significant part of the project.
What materials are recommended in Brussels?
We favor breathable, durable materials suitable for the local style: mineral renders, wood or fiber-cement cladding, natural slate, wood imitation joinery...
How long does a complete exterior project take?
Between 3 and 8 weeks depending on the scope. We establish a precise schedule from the start, coordinating between each trade.
Can insulation be done without altering the appearance?
Yes. Many finishes allow for maintaining a traditional style (brick imitation cladding, tinted renders, custom joinery...). We help you make the right choices.
