Masonry works in Liège

Common cases in Liège: our answers

Before intervening, we conduct a building assessment (cracks, plumb, load, humidity) and then propose the safest solution at the best overall cost. The examples below illustrate our hands-on approach.

• Opening the kitchen to the living room: shoring, controlled cutting, installation of a IPN/HEB, clean covering ready for Gyproc and finishing of the frames. Result: bright space, smooth circulation, solid support for the future kitchen.
• Brick facade with porous joints: removal of old joints, suitable repointing (color/texture) and replacement of cracked bricks; supports reinstated. Result: sanitized facade, infiltrations stopped.
• Annex on the ground floor (kitchen/dining room): earthworks, foundations, reinforced slab, elevations; clean connection with the existing structure to prepare for joinery and insulation. Result: flat and durable base.

Urban planning, neighborhood & co-ownership (Liège / Wallonia)

In a masonry project, the rules change depending on whether or not we touch the structure and the appearance of the facade. Creating a visible opening, modifying a facade, or erecting an annex may require a Prior Urban Planning Declaration (DUP) or a Urban Planning Permit (PU).  :

• Discreet interventions, without altering appearance or structure
  Ex.: repointing identical to the original, local brick repair, reinstatement of non-visible plinth.
  → In principle without permit or declaration (subject to specific situations: listed property, protected perimeter, municipal regulations, etc.).
• Small exterior or visible works, without structural impact
  Ex.: identical replacement of supports/sills in blue stone, lightweight non-supporting low wall, minor decorative reinstatements.
  → Depending on the case, Prior Urban Planning Declaration.
• Works impacting the facade or structure
  Ex.: creation/expansion of a opening in the facade, opening of a load-bearing wall (IPN/HEB, concrete lintel), underpinning, supports, significant modification of the profile.
  → Urban Planning Permit generally required.

Our role: we check your situation and compile the appropriate file (surveys, detailed plans, “before” photos, stability note from the engineer for IPN/HEB, description, phasing). In co-ownership, we prepare the note for the property manager/AG. On the construction side, we manage shoring, security, scaffolding/roadworks, and party walls.

In co-ownership, facade and structure are often common parts: an agreement property manager/AG is required. We prepare the necessary documents (plans, description, photos, colors), organize the signage if it affects the sidewalk, and plan the removal of debris for clean circulation.

Frequently Asked Questions

Before starting masonry work, questions arise about structural feasibility, timelines, cohabitation with the site, and procedures. Here are concrete answers tailored to the Liège context.

How can I tell if a wall is load-bearing and if I can open it?

The thickness, the support of the floors, and the layout of the building provide clues, but only a diagnosis (surveys, structural reading, sometimes calculations) can provide a definitive answer. In most cases, opening is possible with shoring and a properly sized lintel.

Can I stay in the house during the work?

For light interventions (non-load-bearing walls, small slabs), yes with protections and phasing. For a load-bearing wall or a large opening, access is restricted during shoring and curing; we organize key moments at the least disruptive times.

Repointing a facade: aesthetic or real protection?

Joints also ensure waterproofing. Proper repointing (depth, compatible mortar, repair of damaged bricks) extends the life of the facade and limits infiltration; a breathable water repellent can be discussed on a case-by-case basis.

How long does it take to open a load-bearing wall and install a steel beam?

Generally 1 to 3 days for the structure (preparation, shoring, profile), then 1 to 2 interventions for frames and connections. Access (floor/central area) and span influence the schedule.

What permits should be anticipated?

As soon as there is a change in appearance or structure, a DUP or PU may be required; in co-ownership, the syndic/AG agreement is necessary. We prepare the files and organize signage and evacuations if the work affects the roadway.
