Process of a facade project

The initial diagnosis examines the condition of the support and identifies priority areas to be treated before proposing a treatment suitable for the existing material.

Cleaning always precedes the repair of cracks, followed by the application of the new coating or paint. The scaffolding remains up for the entire duration of the project.

A standard restoration project lasts from one to three weeks depending on the facade area and the extent of the necessary repairs. Weather conditions also influence the schedule: some coatings cannot be applied in high heat, frost, or rain, which can delay planning by a few days depending on the chosen season.

External thermal insulation and facade: a combined project

Taking advantage of a facade project to add external thermal insulation allows for addressing two distinct issues in a single intervention: the appearance of the wall and its energy performance. The scaffolding already in place reduces the cost of the second operation, as its setup represents a significant portion of the budget for a separately conducted insulation project.

The energy savings are especially noticeable in older brick houses, where solid walls without an air gap lose a significant amount of heat in winter. External insulation of 10 to 14 centimeters, combined with a finishing coat, significantly improves indoor comfort without reducing the living space, unlike insulation installed from the inside.

Maintenance and durability of your facade

A properly applied coating and suitable water-repellent treatment extend the lifespan of the facade by several years. Regular visual inspections, once or twice a year, allow for the detection of emerging cracks or areas where moisture begins to seep in, before it spreads to the rest of the wall.

Gutters and downspouts also play a direct role in the longevity of the facade. A clogged or poorly fixed gutter pours water directly against the wall, accelerating the appearance of black stains and moss, especially on north-facing facades or those shaded by nearby trees.

Regulations and grants in Wallonia

A modification of the exterior appearance of the facade, such as a change in color or material, generally requires municipal authorization, especially in protected neighborhoods.

External thermal insulation may be eligible for Walloon grants as well as a reduced VAT rate of 6% for homes over ten years old. The reform of housing grants scheduled for October 1, 2026, will further favor comprehensive renovations over piecemeal interventions, an element to anticipate for homeowners considering multiple work items in the coming years.

Signs of wear, authorization, and suitable materials for old buildings

Widening cracks, persistent moss, or peeling coating are clear signals justifying a quick diagnosis. Changing the color of your facade usually requires prior authorization from the urban planning department in most municipalities, as any change in exterior appearance is concerned. Lime-based coating remains the most suitable for old stone or brick facades, thanks to its ability to allow the wall to breathe.

Associated insulation, timeline, and partial or complete treatment

Taking advantage of the renovation to integrate external thermal insulation is highly recommended: it avoids reopening the site a few years later and allows for the cost of scaffolding to be spread over the two items carried out simultaneously. Expect one to three weeks for a facade renovation depending on the surface area and extent of repairs, a timeline that also depends on weather conditions. A localized treatment remains possible for a degraded area, but a perfect color match between the old and new paint is never guaranteed: on a facade visible from the street, a complete treatment avoids an unsightly patchwork effect. Repainting a facade already insulated from the outside is possible, provided that a paint compatible with the type of finishing coating applied to the insulation is used. A poor choice of product can harm the breathability of the system and cause premature blistering. A properly applied and maintained coating generally lasts between fifteen and twenty-five years, depending on the wall's exposure to the elements and the quality of the original substrate.

Enhance your facade with Avenir Rénovations

A well-maintained facade sustainably protects the building while significantly improving its perceived value in the real estate market.

Our teams visit Charleroi and each of its sections, providing a free diagnosis that examines the actual condition of your facade before any final estimates.

In Mont-sur-Marchienne, where the hilly terrain exposes certain facades more to the elements than others, a precise diagnosis allows us to identify the most vulnerable areas before they visibly deteriorate. Unfortunately, many homeowners wait for significant cracks to appear before taking action, whereas preventive maintenance often costs much less.
