Exterior renovation in Marche-en-Famenne

The Walls and Insulation: The Invisible Efficiency

External Insulation: Eliminating Thermal Bridges at the Source

Behind the facade cladding lies the very structure of the dwelling. The renovation of each exterior wall is an opportunity to correct the thermal bridges responsible for indoor condensation and discomfort in winter.

Insulating the walls from the outside has become the norm in Wallonia for high-performance renovations. By wrapping the house in a continuous insulating layer, cold spots are eliminated. Comfort improves immediately: no more feeling of a "cold wall" in winter, and favorable thermal inertia in summer.

Old Masonry: Check the Structure Before Finishing

In the old buildings of Aye or Hargimont, it is sometimes necessary to install ties or reinforce certain lintels before starting the finishes. The exterior masonry must be structurally sound to sustainably support the new coverings. This attention to constructive details distinguishes the work of Avenir Rénovations.

Joinery and Details: The Finishing Touch That Matters

Frames and Glazing Replacement: The Complement to Wall Insulation

A comprehensive exterior renovation does not close without replacing the old frames. Switching to high-performance double or triple glazing is an essential complement to wall insulation. We install joinery in PVC, aluminum, or wood, chosen to harmonize with the new face of the facade.

Unique Points, Edge Finishes, and Restoration

Unique points receive special attention: blue stone thresholds, window sills, choice of the front door — both secure and welcoming. The eaves and edge boards are made from maintenance-free materials (PVC or Alulux) to spare you the hassle of high painting chores.

The final adjustment of each element ensures impeccable air and water tightness. Our teams also ensure complete cleaning of the surroundings: removal of debris, window cleaning, tidying up the garden.

The value of a single point of contact: coordinated roofing, facade, and frames

No re-plastering after the roofer: a continuous project that changes everything

When roofing, facade, and frames are managed by different companies, the interfaces are often poorly handled. The roofer finishes their part without considering the connection with the facade coating. The facade worker takes over hastily. The carpenter installs their frame without paying attention to the insulation returns. The result: residual thermal bridges, costly interior plaster repairs, and an envelope that is never truly airtight. At Avenir Rénovations, a single site manager oversees everything — roofer, facade worker, carpenter. The interfaces are planned in advance, not caught up in an emergency.

Continuity of insulation without thermal bridge at the facade/roof junction

The junction between roof insulation and facade insulation is one of the most critical points in an energy renovation. In Famenne, where winters are harsh, a thermal bridge at this point leads to condensation under the gutters, moisture stains on the cornice plaster, and a measurable loss of efficiency on your heating bill. Our specialists ensure the continuity of the insulating layer from top to bottom of the envelope — a guarantee that only a single point of contact can truly provide.

Your trusted partner in the Marche-en-Famenne region

Rooted locally in Marche-en-Famenne, we understand the constraints imposed by the terrain and climate of Famenne. We operate throughout the greater Marche — Waha, Marloie, Aye, Hargimont, On — as well as in neighboring municipalities: Rochefort, Ciney, Hotton, Nassogne, and Durbuy.

Working with us means benefiting from a single point of contact for all your outdoor fit-out projects. No coordination to manage between the roofer, facade worker, and carpenter: we oversee everything from A to Z.

Common issues and our solutions

Facade coating applied on untreated damp support — rapid detachment

A plaster applied to a facade that is still damp or poorly dusted detaches within a few freeze-thaw cycles, revealing blisters and unsightly detachments. In Marche-en-Famenne, facades exposed to the north or west remain damp long after rainfall. We systematically treat the support — drying, consolidating base, and priming — before any coating application, to ensure lasting adhesion over time.

Frames replaced but residual thermal bridge on the bay returns

Replacing frames without treating the bay returns — the masonry or concrete framing around the opening — leaves a thermal bridge that neutralizes part of the expected thermal gain. This results in condensation on the interior plaster at the edges of the windows, despite new glazing. During each frame replacement, we offer insulation for the reveals and window sills to eliminate this residual thermal bridge.

Overflowing gutters silently attacking the foundations

A gutter blocked by leaves or with a faulty end joint spills rainwater along the wall instead of into the downspout. Over time, this water seeps into the ground at the base of the facade and degrades the foundations and basement plaster — damage that is rarely visible until it is advanced. We clean and check all the metalwork during each intervention on the roof or facade, to put an end to this type of gradual degradation.

Frequently Asked Questions

In what order should exterior renovation work be carried out?

The logical order always starts with the roof, which determines the protection of everything else. Next, we address the facades and walls — including external insulation if planned — before finishing with the replacement of frames and detailed finishes. Following this sequence prevents damage to new elements during subsequent interventions.

Can facade renovation and external insulation be combined to benefit from Walloon grants?

Yes, and it is even recommended. In Wallonia, grants related to the building envelope cover both wall insulation and facade treatment when the work is carried out together. A prior Housing Audit helps identify priority interventions and optimize the amount of available aid.

Does exterior renovation improve the EPC score of my home?

Yes, significantly. Roof insulation, external wall insulation, and frame replacement are precisely the items that weigh the most in the EPC calculation. A better EPC certificate enhances your property's value at resale and may grant you access to more favorable financing conditions.

Can exterior renovation work be carried out in winter in Marche-en-Famenne?

Some work, such as frame replacement or zinc work, can be organized in the cold season. However, facade coatings and paints require minimum temperatures to adhere properly. We plan the sites taking into account the climatic constraints specific to Famenne.

Does Avenir Rénovations handle the entire project, or do I need to hire multiple companies?

Avenir Rénovations acts as a single point of contact for all your exterior work: roofing, facade, insulation, and carpentry. This greatly simplifies coordination and ensures technical consistency between each trade throughout the project.
