Facade renovation in Namur

Facade diagnosis: the basis for a successful renovation

Before acting, we diagnose the substrate: facing brick, stone, existing coating, concrete, exposed areas (North/West facades). We identify:

• Soiling (pollution, mosses, efflorescence),
• Crumbly joints,
• Cracks (chimneys, lintels, window frames),
• Infiltrations (supports, cornices, metalwork),
• Peeling paint or coating,
• Condition of gutters, downspouts, and blue stone supports.

This diagnosis guides the protocol: cleaning method, masonry repairs, choice of finishes, and, if relevant, insertion of external insulation.

Typical cases in Namur: our response

Brick facade, porous joints, aged color

We clean, replace damaged bricks, repoint with suitable mortar (local color), then apply breathable water repellent. Result: fewer infiltrations, enhanced bricks, easier maintenance.

Cracked coating, stains, and microcracks

After cleaning and repairs (bridging cracks, reinforced coating), we apply a siloxane/silicate paint or a compatible render. The result is homogeneous, durable, and breathable.

Signs of moisture at the bottom of the facade

We check the plinths, capillarity, water drainage from supports, and indoor ventilation. Before any finishing, we remediate (drainage if possible, anti-rising barrier if necessary) to avoid trapping moisture.

Facade highly exposed to wind/rain

We prioritize highly water-repellent and resistant systems, address the metalwork (gutters, downspouts), and ensure proper water drainage and edges.

The advantages of Avenir Rénovations 

• A single point of contact for everything: diagnosis, cleaning, repairs, finishing, ETICS.
• Local contractors: mastery of Namur's architecture (bricks, blue stone, coatings), logistics in the city center.
• Clear quotes: options (paint/plaster/ETICS/cladding), phased planning, progress photos.
• Quality control: color samples, occasional cleaning tests, step-by-step receptions.
• Safety & cleanliness: protections, nets, signage, clean disposal of debris.
• Energy advice: opportunity for insulating facade, coordination with frames and ventilation (VMC).

Urban planning, co-ownership and season

Urban planning – City of Namur

• Cleaning and simple repairs: generally without a permit.
• Change of appearance (color, plaster, cladding) or external insulation: declaration or permit possible depending on the case.
  We help you prepare the file (plans, photos, description, colors) and check local requirements (templates, materials, rainwater).

Co-ownership (apartments)

The facade is often a common area: you need the agreement of the general assembly/syndic. We prepare a clear file, organize logistics (protection of common areas, schedules, signage).

Season & weather

We plan the work during an appropriate weather window to ensure adhesion, setting, and durability of the systems (avoid frost/heavy rain).

Common issues: our answers

Paint that chips quickly: why?

Often a non-cohesive surface, poorly cleaned or an inappropriate paint (wrong system). We test adhesion, prepare properly (stripping/primers), choose a compatible system (acrylic/siloxane/silicate) and respect drying times. The film holds, the color remains stable.

Water repellent: does it “prevent the wall from breathing”?

A breathable water repellent allows vapor to pass while repelling liquid water. Used on a healthy and dry surface, it limits soiling and water penetration without trapping moisture. We assess the relevance on a case-by-case basis.

Plaster or paint: what to choose?

Paint (on brick or healthy plaster) offers a visual refresh with a contained budget. Plaster provides a texture and better masks irregularities; applied on ETICS, it adds true thermal performance. The choice depends on the condition of the surface, the budget, and the desired finish.

Should insulation be done from the inside or outside?

For the facade, outside (ETICS) is the most homogeneous solution (reduced thermal bridges, new appearance). Inside remains feasible room by room, but does not fit into a pure facade renovation and impacts the interior surface. We analyze your house, its street alignment, and your energy performance goals.

How long does a facade renovation take?

Depending on surface and complexity: 1 to 3 weeks for cleaning + repairs + painting/plastering of a single-family home. ETICS or cladding require more time (surface, window details). We provide a phased schedule and inform neighbors during noisy stages.

Maintenance tips after renovation

• Gently rinse sensitive areas (dirty drops, bottom of the facade).
• Monitor gutters/downspouts in autumn (leaves).
• Avoid aggressive high pressures.
• An annual visual inspection quickly identifies early signs of disorder (joints, microcracks).
