Exterior door installation cost in Luxembourg (2026)

Luxembourg residential door pricing falls into four material lanes. The leaf cost varies by a factor of three between PVC and high-end aluminium; the install cost is much steadier.

The cost stack on a standard aluminium front door, RC2, Uw 1,1, replacement in existing frame:

• Door leaf supply (90 × 210 cm, factory-finished) → €1 050
• Multi-point lock and cylinder set, 3 keys → €140
• Old door removal and disposal → €60
• Frame check, packing shims, levelling → €50
• Hinge transfer or new hinge fit → €80
• Air-tightness band and silicone seal → €90
• Fitter labour, 4 hours at €52/hour → €208
• Mobilisation and quote → €80
• Net total: €1 678 / 1,17 = €1 434, brutto at 17 %: €1 678

Hidden cost drivers:

• New frame required (rotten wood, distorted PVC, change of door axis) — adds €220–€420 including disposal of the old frame
• Different opening size (existing frame 88 cm wide, new door 90 cm) — adapter frame or masonry rework adds €180–€350
• First-floor or above in a copropriété — manual carry up stairs adds €80–€160, lift permit if available
• Glass insert with safety film or laminated pane — adds €140–€280
• Smart lock (motorised, fingerprint, app) — adds €280–€650 including wiring

A headline price of €490 TTC for "porte d'entrée fournie posée" almost always means a base PVC leaf, no air-tightness band, no disposal line and a basic cylinder. Confirm the spec sheet matches.

The single biggest price split on an LU door job is whether the existing frame stays in place. A block-only swap takes 2 to 3 hours and is cheap. A full frame replacement takes a day and brings the masonry back into play.

Block-only replacement (in the existing frame):

• Existing frame is sound, plumb and the right size for a stock door
• The fitter unscrews the old hinges, lifts the old leaf, fits the new leaf to the same axis, swaps the strike plate, finishes with silicone and a fresh air-tightness strip
• 2 to 3,5 hours of labour, no masonry, no plaster repair, no painting
• Typical labour line: €220–€420

Full frame replacement:

• Existing frame is rotten, distorted, undersized for a modern thermally broken door, or has a different cross-section than the new product
• The fitter cuts the old frame out, packs the masonry opening for the new frame, sets the frame plumb, foams and bands for air-tightness, fits the leaf, then redoes the interior plaster band and exterior render touch-up
• 5 to 8 hours of fitter labour plus often a small mason or plasterer hour for the finish
• Typical labour line: €480–€780, plus €80–€220 of plaster/render finish

When the contractor will insist on a full frame:

• Wood frame older than 30 years with visible rot at the threshold
• PVC frame from 1995–2005 with thermal cracks
• Aluminium frame without thermal break (cold-bridge)
• A change of door type (e.g. solid wood to aluminium glass-insert) where the rebate depths don't match
• Insurance demand for a higher security class — the frame is rated together with the leaf

The pre-2000 LU housing reality:

• Frames installed before 2000 in older Esch-sur-Alzette, Differdange and Dudelange housing stock often need full replacement to hit the modern Uw ≤ 1,3 W/m²K target
• Frames in newer Bettembourg, Mersch and Wiltz developments (post-2008) are usually still acceptable for a block swap

A small sanity check before the visit:

• Open the door to 45° and see if the latch slides freely. If it sticks, the frame is out of plumb — full replacement is likely
• Run a finger along the threshold from inside. If you feel a draught, the air-tightness is gone — at minimum the threshold and band need replacing
• Check for water staining at the bottom interior corner — sign of frame rot inside the masonry

Net effect on price:

• A €690 TTC quote for "porte d'entrée pose" is block-only
• A €1 480 TTC quote on the same address is usually full-frame
• The €790 difference is real work; do not assume the higher quote is over-priced

The right question to ask:

• "Does your quote replace the frame, or fit the new leaf into the existing frame?" — get the answer in writing before signing.

Two technical numbers drive the LU door price more than the brand: the U-value (Uw) and the burglary class (RC). Both feed into the renovation incentive eligibility and the home insurance premium.

The Uw scale (whole-door U-value, W/m²K):

• Uw ≥ 1,8 — old, bare PVC or non-insulated wood. Not eligible for any LU renovation incentive
• Uw 1,3–1,7 — modern stock PVC. Acceptable for replacement but rarely qualifies for the highest incentive bracket
• Uw 1,0–1,3 — thermally broken aluminium, insulated steel, modern wood with insulated core. Qualifies for the standard logement.lu renovation premium
• Uw 0,8–1,0 — passive-house grade. Premium price, premium incentive

The RC scale (resistance class, EN 1627):

• RC1 — basic anti-trespass, deters opportunists. Most stock PVC doors
• RC2 — resists 3 minutes of attack with simple tools. Insurer's typical minimum for ground-floor doors in Luxembourg-Ville and Esch
• RC3 — resists 5 minutes with leverage tools. Standard for high-value households or houses in isolated communes
• RC4–RC6 — commercial / specialist; rare in residential

The price impact, in round numbers:

• Stepping from Uw 1,5 to Uw 1,1 → + €80–€140 on the leaf
• Stepping from Uw 1,1 to Uw 0,9 → + €120–€220 on the leaf
• Stepping from RC1 to RC2 → + €180–€320 on the leaf
• Stepping from RC2 to RC3 → + €280–€480 on the leaf

Insurance angle:

• LU home insurers price the burglary risk on the front-door class. A house insured at content value above €40 000 is increasingly required to have an RC2 front door
• Some insurers offer a 5–10 % premium discount for an RC2 door with a multi-point lock and a certified cylinder (VdS / SKG / VSÖ)
• A claim after a burglary can be challenged if the door class is below the insurer's stated minimum — confirm in writing before installing

The renovation incentive (logement.lu, prime myenergy):

• The Uw threshold for the standard premium typically sits around Uw ≤ 1,3 W/m²K for entry doors
• Documentation: factory data sheet (Leistungs­erklärung / DoP) showing the Uw, plus the installer's invoice with material reference
• The premium runs roughly €80–€200 per door at current rates, paid after the work and after a compliance check

The cylinder and key control:

• A multi-point lock without a certified cylinder is RC1 in practice — the cylinder can be drilled in 60 seconds
• A VdS class B / SKG 3-star cylinder costs €90–€180 and lifts the door from RC1 to functional RC2
• Coded keys (registered cylinder) prevent unauthorised duplication — useful for houses where keys are held by family, cleaners and tradesmen

The pragmatic spec for an LU front door:

• Aluminium or insulated steel, Uw ≤ 1,2, RC2, certified multi-point lock, certified cylinder, full air-tightness band
• Expected install all-in TTC: €1 350–€1 750
• Expected logement.lu premium back: €80–€180
• Net cost after premium: €1 200–€1 600

In Luxembourg, a meaningful share of door installations happen in copropriété buildings, where the door — especially the front door of a flat or the building entry door — sits at the boundary between private and common parts. The administrative path matters as much as the technical spec.

Private flat entry door (door from the common stairwell into your flat):

• The door leaf and lock are typically private property, but the exterior face of the door is often considered part of the building's visual unity (règlement de copropriété)
• A change of colour, of material (wood to aluminium) or of design usually requires syndic approval
• A change of leaf only, keeping the same exterior finish, is usually allowed without a vote
• The fire-rating of the door (often EI30 or EI60) is non-negotiable in newer LU buildings — replacing a fire door with a non-rated one is a serious compliance breach

Building entry door (the street-level door):

• This is unambiguously a common part. Replacement requires a copropriété vote (assemblée générale)
• The cost is shared by all owners on the basis of the tantièmes
• A typical building entry door in a small LU residence (10 to 20 flats) costs €2 800–€4 800 TTC for an aluminium door with intercom, electric strike and Uw ≤ 1,3
• The syndic typically tenders 3 quotes and circulates them ahead of the AG

Required syndic paperwork before any replacement:

• Written request to the syndic with the proposed door spec (DoP)
• Photo of the existing door, dimensions, colour
• Confirmation that the new door respects the building's visual unity
• For fire-rated doors, the EI rating certificate
• Insurance: contractor's RC pro and décennale on file
• Evidence the contractor has Autorisation d'établissement and Chambre des Métiers registration

Lift and stair use during install:

• Most syndics require a lift cover (protective blanket and corner protectors) during transport — €30 to €80 per day
• The fitter is responsible for cleaning the stairwell after the work
• Some buildings ban deliveries during specific hours (early morning, evening, weekends)

Ground-floor entries on private houses:

• No syndic, but the commune may have a "patrimoine bâti" view if the house sits in a heritage perimeter (Luxembourg-Ville old town, parts of Wiltz, Echternach centre)
• A change of colour or material on a heritage façade requires a déclaration to the commune urbanisme service before the work
• The commune can refuse a non-compliant choice or demand a specific tone — adds 2–4 weeks to the timeline

A practical syndic-friendly checklist:

• Match the existing exterior colour and finish unless you have AG approval to change
• Stick to the existing leaf dimensions where possible to avoid masonry rework on the common-part side
• Coordinate the fitting day with the syndic's caretaker for stairwell cleanliness
• Take photos of the stairwell and lift before and after the work — protects you if a damage claim is raised
• Get the syndic's written acknowledgement of the work after completion — closes the loop

The stop-work risk:

• A door installation begun without syndic approval can be ordered torn out at the owner's cost
• A compliance breach on a fire door can void the building insurance for everyone
• A heritage breach in a protected commune can trigger a fine of €500–€2 500

The administrative load is modest if planned 3 to 6 weeks ahead, expensive if treated as an afterthought.

Door installation in Luxembourg is invoiced at TVA 17 % by default. The 3 % super-reduced regime under logement.lu can apply when the work is part of a renovation of a primary residence over 10 years old.

The TVA picture for door installation:

• Stand-alone door replacement on primary residence over 10 years — usually qualifies for TVA 3 % if framed as a renovation
• Door installation in a new build — TVA 17 %, no reduced regime
• Door installation in a primary residence under 10 years — TVA 17 %
• Door installation on rental or commercial property — TVA 17 %
• Building entry door replacement on a copropriété — TVA 3 % typically when the building is over 10 years old, dispatched per tantième

Example on a €1 678 TTC standard alu front door:

The €201 saving at 3 % is meaningful and routinely accessible on door work in eligible dwellings — provided the contractor handles the paperwork. Many contractors will quote 17 % by default and switch to 3 % only if the customer asks; the burden is on you.

Documents required for 3 %:

• Certificat de résidence and proof of primary-residence status
• Notarial deed or cadastre extract showing the dwelling is over 10 years old
• Single contract framing the work as a renovation (mention "rénovation porte d'entrée" rather than "fourniture porte" only)
• Contractor's written commitment to defend the 3 % rate at a tax audit

The aggregate cap:

• The 3 % super-reduced regime is capped per dwelling (currently around €50 000 of cumulative eligible work). A door is a small line; the cap rarely binds for door-only projects but matters if you have a wider renovation underway

Practical recommendation:

• For any primary-residence over 10 years, ask the contractor explicitly whether they will issue the invoice at 3 %. If they refuse without a clear reason, take a different bidder
• Keep all paperwork (contract, factures, energy certificate) for at least 5 years in case of a TVA audit
• For copropriété building entries, the syndic handles the 3 % paperwork on behalf of the owners

A common mistake:

• Splitting "door supply" and "door installation" into two separate invoices can cause the supply line to be charged at 17 % even when the install qualifies at 3 %. Keep both lines on a single contract under a renovation framing to maximise the reduced-rate exposure.

A second common mistake:

• Confusing logement.lu super-reduced TVA (3 %) with the energy renovation premium (paid cash after the work). They are independent — you can claim both on the same eligible job.

Three door quotes for the same opening typically spread by 25 to 60 % because each contractor specs the leaf differently and reads the install scope differently. The cheapest bid on a vague brief is rarely the lowest final price.

The five anchor points:

• Door material and product reference — manufacturer, model number, factory finish, dimensions exactly named
• Uw value and security class — RC1/RC2/RC3 explicit, certified cylinder confirmed
• Install scope — block-only or full frame, threshold replacement or kept, air-tightness band included or not
• Disposal of old door and frame — included in price or extra
• TVA position — 17 % default unless explicit and documented 3 % qualification

The brief to hand each bidder:

• Photo of the existing door from inside and outside, with a tape measure for scale
• Frame condition (any rot, cracks, gaps)
• Dimensions to mm: width, height, frame thickness, opening side (left/right)
• Existing leaf material and approximate age
• Required Uw target and required RC class (or "tell me what your insurer requires")
• Access route (ground floor, stair flight, lift, balcony delivery)
• Is the dwelling a primary residence over 10 years? (TVA framing)
• Is the building a copropriété? (syndic notice timing)

Pre-award contractor checks:

• Autorisation d'établissement number, Chambre des Métiers registration in joinery / fenêtres-portes
• RC pro and décennale insurance certificates
• Photos of two recent door installs, ideally one of the same brand
• Manufacturer reference and DoP (declaration of performance) for the proposed door
• Confirmation that the cylinder is VdS / SKG certified if RC2 or higher
• Written commitment on the install warranty (typically 2 years on labour, 10 years on the leaf manufacturer warranty)

Reading the spread:

• ±10 % on a clean brief — normal market variance
• 15 to 30 % — typically different leaf class or different install scope
• 30 % and above — often the lowest bidder has assumed block-only when full frame is needed, or has skipped the air-tightness band

The two most common omissions:

• Air-tightness band — required for any modern install but often quietly skipped to win price. Leaves a permanent draught
• Disposal of old leaf and frame — €40–€90 invisibly missing on the cheap bid

A useful tactic:

• Ask each contractor to itemise four lines explicitly: leaf supply (with reference), labour (with hours), disposal, and any plaster/render touch-up. The variance per line tells you who is winning the price by under-spec'ing what

The single most useful question:

• "If on the day you find the existing frame is rotten and needs full replacement, what is the additional cost and how long does the work then take?" — a contractor who can answer this with a clean number is realistic; one who fudges will surprise you mid-job.
