Kitchen renovation in Liège

Materials & compatibilities

Longevity depends on a complete and compatible system. We prioritize professional ranges distributed in Belgium, with reliable after-sales service.

• Partitions: Gyproc/Fermacell (water-resistant near water areas), compatible tapes and coatings.
• Floors: LVT click/glue (easy to maintain), C2 tiles in glue, suitable engineered wood.
• Countertops: laminate (value for money), quartz/ceramic (stain/heat resistance), granite (natural and robust).
• Backsplashes: tiles (waterproof joint), lacquered glass, large format ceramic, stainless steel behind the cooktop.
• Electricity: equipment compatible with wet areas, differential protections compliant with RGIE.
• Ventilation: ducts carefully sealed, external discharge if possible.

Common issues observed in Liège

We address the cause, not just the appearance.

• Insufficient or poorly placed outlets: adding worktop circuits, dedicated lines, discreet conduits.
• Poorly thought-out lighting: shadows, glare; adding LED strips under furniture, rail above preparation areas.
• Ineffective hood: switching to extraction with external discharge when possible, recalculating flows.
• Worktops that mark: choosing more durable materials (quartz/ceramic) or refurbishing edges/joints.
• Peeling coverings: redoing primers, suitable adhesives, drainage joints if necessary.

Urban planning procedures & co-ownership (Liège / Wallonia)

Most interior works are exempt from procedures. However, modification of exterior appearance (new hood grille on the facade, changing frames, creating/extending openings) may require a Prior Urban Planning Declaration (DUP) or a Building Permit (PU) depending on the municipality.

In co-ownership, technical columns, ventilation ducts, and facades are common areas: a syndic/AG vote is required. We prepare a clear file (plans, description, colors, technical diagrams) to facilitate agreement.

Grants & Taxation (Wallonia – 2025-2026)

There is no regional grant for kitchen furniture or simple decoration. However, certain components energy/health may qualify for Housing Grants (temporary scheme in Wallonia, amounts varied by income category R1→R5, often via Housing audit):

• Ventilation (correct flow rates, mechanical ventilation if part of a global project),
• Insulation of adjoining walls (if you are treating walls/ceilings as part of an energy project),
• Exterior joinery (if replaced during renovation),
• Hot water/heating production if the project connects to it.

For a private dwelling > 10 years, 6% VAT may apply to improvement/repair works (conditions). We check these options without over-promising and plan the works to optimize the aids when they are available.

FAQ

Extraction or recycling: which hood to choose?

Extraction to the outside remains the most effective: it removes steam, grease, and odors. It requires a sealed duct, a backdraft damper, and a compliant discharge point on the facade/roof. Recycling is useful when extraction is impossible (condominium, facade constraints): it filters and returns air to the room but requires regular maintenance of the charcoal filters and is less efficient. We size the flow rate (in m³/h) according to your volume and usage.

Can I live on-site during the renovation?

Often yes, provided there is a clear phasing: temporary kitchen (temporary sink, mobile plates), planned noisy periods, protections, and daily cleaning. We work by zones to reduce disturbances and maintain a minimum level of comfort.

Is it complicated to move the sink and the cooktop?

Moving the sink involves extending the supply and drainage (slopes, diameters, siphon), sometimes a lift pump if there is a negative slope. Moving the cooktop requires a dedicated line (electric) or gas adaptation by a certified professional, and repositioning of the hood. We check feasibility, costs, and aesthetics before making a decision.

What flooring should I prefer in the kitchen?

LVT is comfortable, stable, and easy to maintain; tiles excel in high-traffic areas and with underfloor heating; engineered wood is suitable if the finish is appropriate and maintenance is regular. We compare slip resistance, water resistance, acoustics, and style to decide.

How long does a typical project last?

From 7 to 15 working days for a standard renovation (excluding heavy custom work), and 3 to 4 weeks for a complete transformation with technical relocations and full finishes. The timeline depends on supplies (plans, appliances, tiles) and approvals.
