Drywall installation cost in Luxembourg (2026)

Typical build-up on a standard 10 cm bedroom partition:

• Metal track 98 mm + studs at 60 cm
• 45 mm mineral wool (acoustic rating 37 dB)
• Single plasterboard (12,5 mm) both sides
• Three-coat jointing, sanded to level Q3
• Ready-for-paint at ~€70/m²

Thickness breakdown of common partitions:

• 72 mm total (48 mm track + 12,5 mm board each side): light partition
• 98 mm total (standard bedroom, good acoustic)
• 148 mm total (double-board fire or acoustic stairwell)

Minimum fees:

• Small jobs under 15 m² may carry a site-day minimum of €550–€850 TTC regardless of m² calculation, to cover mobilisation costs and 1 day on site with two tradesmen.

Build-up choice depends on the performance requirement. Specify before quoting.

Acoustic performance:

• Rw 37 dB (single 12,5 mm board each side, 45 mm mineral wool): baseline bedroom-to-bedroom privacy
• Rw 43 dB (single board each side, 70 mm mineral wool, decoupled studs): good for bedroom to living room
• Rw 50 dB (two boards each side, 70 mm mineral wool, staggered studs): apartment-to-apartment demising
• Rw 55+ dB (independent double-frame system with acoustic mats): recording studio, medical practice

Luxembourg residential rule of thumb:

• Bedroom-to-bedroom in same apartment: Rw ≥ 37 dB
• Apartment demising wall: Rw ≥ 55 dB (code — DICR 2016 thermal+acoustic regulation)
• Hotel room: Rw ≥ 52 dB

Fire performance:

• EI 30 (single 12,5 mm type F or GKF board each side): interior compartment in residential (30-min fire resistance)
• EI 60 (two 12,5 mm type F boards each side, double layer): stairwell, service shaft, boiler room
• EI 90 (specialised build-up, thicker boards): multi-storey shaft, technical room, commercial

Luxembourg code (DICR 2016, ITM):

• Stairwell enclosure in multi-storey residence: EI 60
• Lift shaft: EI 60
• Residential boiler room (>70 kW): EI 60 with EI 30 self-closing door

Moisture and splash zones:

• Standard bathroom wall (outside of splash zone): normal plasterboard acceptable, skimcoat to Q3
• Splash zone around shower or bath (up to 2 m height): green board (H2 rating) or cement board, tiled finish
• Laundry room with washing machine: green board minimum
• Swimming pool or sauna wall: cement board + waterproof membrane

Cost delta for upgrading from standard:

• Green board instead of standard plasterboard: +€4–€8/m²
• Cement board instead of standard: +€10–€18/m²
• Acoustic upgrade (70 mm wool + decoupled stud): +€15–€25/m²
• Fire upgrade from standard to EI 30: +€10–€18/m²
• Fire upgrade from EI 30 to EI 60: +€18–€32/m²

A bedroom partition upgraded for acoustic from 37 dB to 50 dB adds €15–€25/m² on the base price.

The joint-finishing quality level drives the paint-ready state — and the price. German-standard Q-classification used across Luxembourg.

Q1 — basic:

• Single joint compound fill on tape only
• Fastener heads filled
• Visible joint line remains
• Suitable for substrate to be tiled, clad with panel, or behind wardrobe
• Included in standard €45–€95/m²

Q2 — standard decorative:

• Three-coat joint compound
• Fasteners filled and sanded
• Joints blended with surrounding surface to within 3 mm
• Suitable for textured paint, matte wall paper, or basic matte paint
• €0–€5/m² over Q1

Q3 — high decorative:

• Full three-coat with additional broad-edge feathering
• Fastener heads fully hidden
• Surface smoothed to within 1 mm deviation
• Suitable for satin paint, fine wallpaper, or standard decorative finish
• +€6–€10/m² over Q2

Q4 — premium / grazing-light:

• Full skim-coat over the entire surface (not just joints)
• Sanded to a continuous uniform surface
• Suitable for high-gloss paint, metallic paint, pigmented satin, grazing light conditions
• +€15–€25/m² over Q2

Choosing the right Q level:

• Bedroom walls with matte paint: Q2
• Open-plan living room with large windows (grazing light): Q3
• Feature wall with satin or semi-gloss paint: Q3 minimum, Q4 if the paint is very reflective
• Bathroom with glossy paint above splash zone: Q3
• Ceiling directly under pendant lighting: Q3 if light is close to the surface; Q4 if light is less than 15 cm from the ceiling

Common mistake: Specifying Q2 and expecting a glass-smooth wall. If the client will paint high-gloss satin over the partition, Q3 minimum is required. Asking for Q3 retrospectively adds €8–€15/m² because the work needs a second sanding pass.

Worked example on a 30 m² partition:

• Q2 standard: 30 × €70 = €2 100 TTC
• Q3 for matte decorative living room: 30 × €77 = €2 310 TTC
• Q4 for grazing-light feature wall: 30 × €92 = €2 760 TTC

Drywall is almost always part of a renovation project, which opens the 3 % super-reduced TVA regime when the dwelling qualifies. For 3 % directly on the invoice, the AED (Administration de l'enregistrement, des domaines et de la TVA) must approve the request before the works start; otherwise 17 % is invoiced and the difference is reclaimed.

Rate by scenario:

• Drywall in existing main residence (owner or tenant) at least 10 years old: TVA 3 % with AED approval (within the €50 000 VAT advantage cap per dwelling)
• Drywall in primary residence <10 years old: TVA 17 % (unless the works take place within 5 years of purchase)
• Drywall in a secondary residence or a flat nobody uses as a main residence: TVA 17 %
• Drywall in commercial office or shop: TVA 17 %
• Drywall in new-build residential: TVA 17 %
• Drywall as part of agreed copropriété works on private apartment >10 years: TVA 3 % on the apartment portion, TVA 17 % on common-area works
• Drywall in a public or subsidised project: as per the project-specific TVA regime

The AED approval process:

1. Owner compiles proof of property (title deed) and proof of primary-residence status (address certificate, identity document)
2. Owner submits the request to the AED with the planned scope and estimated cost, before the works start
3. AED issues the approval (usually within 4–8 weeks)
4. Owner forwards the approval reference to each trade contractor
5. Each invoice issued after the approval cites the AED reference and applies TVA 3 %

Mandatory mentions on a 3 % invoice:

• AED approval reference
• Property address and date of construction
• Scope description (drywall partition / ceiling / lining, m² count, build-up)
• Labour hours and materials separate
• Net HT, TVA 3 %, TTC totals

Worked example on a 30 m² partition at €70/m² TTC:

• 17 % regime: net €1 795 + TVA €305 = TTC €2 100
• 3 % regime: net €1 795 + TVA €54 = TTC €1 849
• Saving on primary residence = ~€251; at €1 795 net the quote is below the €3 000 minimum for direct 3 %, so this goes through a refund claim (invoice above €1 250, claim above €3 000 covering at least 6 months)

For a €14 000 drywall package (TTC at 17 %) in a 2-storey renovation, the saving is ~€1 675.

The €50 000 cap is tracked per dwelling: later eligible renovations (bathroom, roofing) count towards the same cap until it is reached; a fitted kitchen stays at 17 % in any case.

The six checks that matter:

• Trade registration. plâtrier-peintre or plaquiste speciality listed in Autorisation d'établissement; Chambre des Métiers registration verifiable.
• Detailed take-off. m² of each wall type listed (partition, lining, ceiling, fire), per build-up and per room.
• Build-up specified. For each line item — stud size, stud spacing, insulation type and thickness, board type and thickness, finish Q level, acoustic or fire rating.
• Brand of materials. Knauf, Rigips (Saint-Gobain), Gyproc, Fermacell — indicate brand to compare apples with apples.
• Finish quality level. Q1/Q2/Q3/Q4 explicitly stated on each surface.
• Warranty. 10-year décennale under the Luxembourg décennale regime on load-bearing-relevant works; 2 years on standard partitions is the minimum.

Briefing pack to share with each tradesman:

• Floor plan with partition positions marked and dimensions
• Elevations if partitions are curved or have niches
• Acoustic or fire requirements by wall (if multi-family or special use)
• Finish destination for each wall (paint type, tile, wallpaper)
• Power and plumbing routing inside the wall (provide drawings from the other trades)
• AED approval reference if 3 % TVA applies
• Site access constraints (lift-or-stairs for boards, night or weekend restriction)

Typical quote segments in Luxembourg:

• Budget (−25 %): small 1–2-person outfit, local brand or no-brand boards, basic Q2 finish, no warranty on acoustic — useful for garage or utility room lining
• Median: established SME using Knauf or Rigips, Q3 standard, 2-year warranty, AED approval handled — best value
• Premium (+25 %): specialised interior-finish contractor, Q4 grazing-light finish on feature walls, acoustic and fire specialist, 5-year warranty — used for villa, show apartment, medical practice

Quotes on a shared scope cluster within ±15–20 %. A 30 %+ discount usually means reduced insulation thickness, cheaper boards, or omitted Q-level upgrade. Verify each line item and request sample photos of previous work at the stated Q level before selecting.

For a 30 m² partition budget package, the spread typically looks like: €1 700 (budget), €2 100 (median), €2 700 (premium). For a 140 m² house-wide package, typically: €8 500 (budget), €10 000 (median), €12 500 (premium).
