Exterior renovation in Namur

Typical issues in Namur: our response

• Dirty brick facade, crumbling joints → gentle cleaning, repointing, slope/water drainage supports, breathable water repellent.
• Cold walls & high bills → ETICS or insulated ventilated cladding, adjustments to air inlets, coordination with frames.
• Infiltrations at valleys/chimneys → repair of flashings/valleys, under-roof screen, anchoring checks to wind regulations.
• Green terrace & puddles → adjustment of slopes, gutters/drainage, draining joints, non-slip surface.
• Street noise → acoustic laminated glazing and watertight installation, adjustments to ventilation/extractions for stable air quality.

The advantages of Avenir Rénovations

• Single point of contact for facade, roof, exterior carpentry, surroundings, and small works.
• Local craftsmen: knowledge of Namur's buildings (brick, blue stone, slate/tile, hollow walls).
• Transparent quotes with variations (technical/finishes), phased planning, progress photos.
• Quality control: details of waterproofing, fixings, slopes, joints; clean and secure site (scaffolding, nets).
• Multi-lot coordination: no overlaps, well-managed interfaces (ETICS ↔ frames ↔ thresholds ↔ terrace).
• Local after-sales service: adjustments, occasional repairs, maintenance advice.

Urban planning, energy performance & co-ownership

• Urban planning: cleaning and simple repairs → generally without permit. Change of appearance (color, rendering, cladding), ETICS, roof modification, awning/carport → declaration or permit possible. We prepare your file (photos, description, colors).
• Energy performance: works on the envelope (ETICS, frames, roof) are documented (technical sheets, implementation photos) for proper recognition of gains.
• Co-ownership: facade/roof = often common areas. We anticipate AG/syndic, protections for common areas, and logistics (elevator, schedules, signage).

Maintenance & sustainability: our advice

• Facade: gentle rinsing of sensitive areas, annual inspection of joints/supports, avoid aggressive high pressure.
• Roof: clean gutters in autumn, visual inspection after strong winds.
• Terraces: non-slip/appropriate finish, periodic rinsing, targeted anti-moss treatment.
• Joinery: silicone joints/waterproofing to monitor, occasional adjustments of openings.

FAQ - Exterior renovation

What to prioritize if everything needs to be redone outside?

1. Roof & waterproofing (urgent/infiltrations), 
2. Facade (disorders + opportunity ETICS),
3. Frames, 
4. Surroundings & drainage. 

This hierarchy avoids "reverse" work.

What does ETICS mean in exterior renovation?

ETICS stands for "External Thermal Insulation Composite System": an insulation is applied to the facade and then covered with a finishing coat. It combines energy performance and new rendering, with a wide choice of appearances. 

ETICS, simple plaster or cladding: how to choose?

ETICS = thermal performance + new rendering. Plaster on prepared support = aesthetic renewal without insulation. Ventilated cladding = protection + style + modular maintenance. The choice depends on your goals (energy/aesthetics/budget).

Can the house remain habitable during the work?

Most often yes: phased by facades/slopes, maintained circulation, daily protections and cleaning. We communicate the schedule and the noisy stages.

Should the frames be installed before or after an ETICS?

It is decided on a case-by-case basis. Often, replacing the frames before the ETICS facilitates the continuity of the insulation and the supports. We coordinate the interfaces to avoid thermal bridges.

How long for a typical exterior site?

Depending on the scope: 1 to 3 weeks for simple rendering; 3 to 6 weeks for ETICS of a single-family house; 1 to 3 weeks for medium terrace/pathway. A phased schedule will be provided to you.
