Cost to refinish hardwood floors in Luxembourg (2026)

Finish choice drives €4–€10/m² within each row:

• Matt water-based lacquer (Bona Traffic HD, Berger Aquaseal) — popular 2026 choice, 10+ year wear life
• Satin polyurethane — classic finish, slightly amber cast, 10+ year wear life
• Hardwax-oil (Osmo Polyx, Rubio Monocoat) — natural feel, needs re-coat every 4–7 years
• Pure oil — traditional look, re-coat yearly in high-traffic areas; cheapest re-application but most intensive upkeep

Fixed labour lines:

• Edge sanding (20 cm around perimeter) — typically €8–€14/m² add-on on complex rooms
• Gap filling with wood dust + resin — €4–€9/m² on pine strip floors
• Plank replacement (rot, insect damage) — €35–€70 per plank piece
• Colour staining before finish — €8–€18/m²
• Skirting removal and re-fit — €12–€24 per linear metre

On a €2 200 net refinishing job at TVA 17 %: €2 574; at TVA 3 % primary-residence: €2 266 — delta €308.

Quality on a refinishing job is decided by process discipline, not by the brand of machine. A good contractor will talk through each step before quoting.

Step 1 — site preparation (0,5 day):

• Furniture moved out of the room
• Skirtings protected or temporarily removed for a cleaner edge
• HVAC intakes masked; extraction-fan equipment positioned
• Door leaves removed if they clear the current floor height (most will need planing after refinishing)

Step 2 — structural check (0,5 day):

• Walk every plank; identify loose or rotten boards
• Sound-check for hollow spots (glue failure on engineered parquet)
• Decide replacement-board quantity and source before sanding starts

Step 3 — sanding (1 to 2,5 days for 60 m²):

• Pass 1: coarse (40 or 60 grit) to level the surface
• Pass 2: medium (80 grit) across the grain
• Pass 3: fine (120 grit) along the grain
• Edge machine (20 cm strip against walls) follows each pass
• Corner scraping and hand sanding where the edge machine cannot reach
• Industrial vacuum between every pass — not optional

Step 4 — filling + first coat (0,5 day):

• Fine wood-dust resin fills nail holes and hairline gaps
• Tack-cloth the entire floor
• First finish coat applied with lambswool or T-bar depending on product

Step 5 — recoat + handover (1,5 day):

• 4–8 hour cure between coats on water-based lacquer
• Light sanding between coats with 240-grit screen
• Final coat applied in the direction of the board
• Walking permitted after 12 hours on water-based, 24 hours on polyurethane
• Furniture in after 48 hours on lacquer, 72 hours on oil, 10 days for heavy loads on any finish

Total site time for 60 m²: 4 to 6 working days. Plan room-by-room on multi-room jobs so part of the home remains occupiable.

The finish choice shapes look, feel and maintenance burden. Picking the right system for the room avoids premature recoating.

Matt water-based lacquer (most popular 2026):

• Best for: living rooms, corridors, bedrooms, home offices
• Strengths: low VOC, low odour, yellowing-free, fast cure (12 h walkable), 10+ year life
• Weaknesses: slight "plastic" look on some species; repair requires full-coat sand
• Typical cost including material: €38–€48 per m²

Satin polyurethane lacquer:

• Best for: heritage-floor look, kitchen transitions
• Strengths: warm amber cast, high wear resistance, forgiving on application
• Weaknesses: yellows slightly over time; higher VOC during cure
• Typical cost: €34–€44 per m²

Hardwax-oil (Osmo Polyx, Rubio Monocoat):

• Best for: open-plan living, spaces where a matt, tactile surface matters
• Strengths: natural feel, spot repair possible with local buff-in
• Weaknesses: re-coat every 4–7 years in high-traffic zones; delicate against red-wine stains
• Typical cost: €36–€46 per m²

Pure oil:

• Best for: low-traffic dining and bedroom spaces, traditionalist preference
• Strengths: most natural look, cheapest materially
• Weaknesses: annual maintenance coat required in lived-in zones
• Typical cost: €30–€40 per m²

Kitchen and bathroom special cases:

• Engineered parquet designed for wet zones needed — solid hardwood in kitchens must sit behind a drain tray
• Water-based two-component lacquer (Bona Traffic HD) or marine-grade polyurethane for kitchens
• Avoid hardwax-oil under sinks and dishwashers — water rings form within weeks

Pets and underfloor heating:

• Dogs scratch every finish; a slightly textured matt lacquer hides claw marks better than gloss
• Underfloor heating: water-based lacquer preferred (hardwax-oil performs but needs a break-in heat cycle of 72 hours)

Refinishing a hardwood floor can be billed at either 17 % standard TVA or 3 % super-reduced TVA depending on context.

The rate in practice:

• Standalone refinishing on an owner-occupied house where no broader renovation is declared: TVA 17 %
• Refinishing as part of a broader primary-residence renovation (painting, electrical refurbishment, kitchen) on a house older than 2 years, with logement.lu authorisation filed: TVA 3 %
• Refinishing in a rental investment property: TVA 17 %, no 3 % access
• Commercial floor refinishing (office, retail): TVA 17 % with input VAT recovery for registered businesses
• Short-term-rental property refinishing (Airbnb, bed-and-breakfast): TVA 17 %; some single-unit owner-operator cases accept reduced rates but are fact-specific

3 % application:

• Property older than 2 years
• Primary-residence attestation signed by the owner
• Application via MyGuichet.lu BEFORE the refinishing invoice is issued
• Refinishing listed alongside other renovation items in the broader project
• Invoice explicitly references the 3 %-rate and the authorisation number
• Lifetime cap across the dwelling's renovation life applies (currently €50 000 net advantage)

Savings worked example on a €2 200 net 60 m² refinish:

The €308 delta is material on a single-room refinish and stacks with other renovation lines. Floor refinishers who work regularly for home-renovation projects are familiar with the mechanism; generalist painters who occasionally sand may not be. Confirm the rate in writing on the quote before any deposit is paid.

Record-keeping requirement:

• Each invoice must carry the TVA rate, the authorisation number and the contractor's Autorisation d'établissement number
• Keep all invoices for 10 years — AED can audit retroactively
• If you use the property as a rental within 10 years, the VAT saving is subject to reclaim

The €28–€62 per m² refinishing cost is attractive, but it is not always the right economic choice. The decision between refinish and full replacement comes down to four structural factors.

Refinish when:

• Wear layer on solid plank floor is ≥ 4 mm above the tongue — enough thickness for 2–3 future sand cycles
• Wear layer on engineered parquet is ≥ 3 mm — same rule
• Board structure is sound (no rot, no insect damage)
• Gaps between boards are <3 mm — filling with wood-dust resin will hold
• Existing pattern (herringbone, Versailles) has heritage or design value
• Subfloor is flat and uninsulated — no thermal or acoustic improvement needed

Replace when:

• Wear layer thickness < 2 mm on engineered parquet — cannot be sanded without exposing substrate
• Widespread rot, water damage or insect damage affecting more than 10 % of boards
• Floor sits directly on slab with no damp-proof layer and moisture readings above 3 % — new floor with DPM is better
• Underfloor heating retrofit desired — a new floor sits properly above the heating circuit
• Acoustic improvement required to meet LU 2026 regulation in multi-residential buildings

Cost comparison on 60 m²:

• Refinish and re-finish: €1 700–€3 750
• Strip and replace with 14 mm engineered oak parquet + underfloor heating: €6 500–€11 500
• Strip and replace with 18 mm solid oak plank: €9 500–€15 500
• Keep, refinish now, replace in 12–15 years if wear layer is sufficient: €1 700–€3 750 now + €6 500–€11 500 later

The grey-zone case:

• An engineered parquet with 2,5 mm wear layer can be refinished once by hand — €46–€62/m² — but there will be no further cycles
• A solid plank floor with a single deep stain (water damage around a radiator) can have 2–4 boards spliced in during refinish for €180–€450 extra, saving a full replacement

Ask the contractor to measure the wear-layer thickness with a pin gauge before quoting — reputable floor refinishers do this as a matter of course.

Three quotes for a 60 m² hardwood refinishing job in Luxembourg typically span 20–35 % — some of that is margin, most is scope drift.

The six checks that matter:

• On-site wear-layer measurement. Reputable contractors measure thickness before quoting; a flat-rate quote without site visit on an old floor is a red flag
• Number of passes named. Three passes minimum (coarse, medium, fine) + edge work. A quote with only "sand and finish" language leaves room to underdeliver
• Finish product named. Brand and product — e.g., "Bona Traffic HD matt, 3 coats" — not "water-based lacquer"
• Furniture movement included or excluded. Named explicitly; some contractors move furniture as part of labour, others list it separately at €80–€180 per room
• Dust-containment method. Continuous industrial vacuum on all machines; older contractors using open bags should be avoided in occupied homes
• TVA treatment. 17 % or 3 % named, with logement.lu number if 3 %

A clean briefing pack for three contractors:

• Room plan with m² noted per room
• Current floor type (solid oak, pine, engineered parquet, species and approximate age)
• Photos of worst areas (stains, deep scratches, damaged boards)
• Desired finish product (or open to recommendation with named trade-off)
• Site access window (weekdays only, full-week availability)
• TVA treatment and logement.lu status

Red flags:

• Price well below competitors — often excludes edge sanding, furniture move, or uses single-pass sand
• No Autorisation d'établissement on quote header
• "All inclusive" language without itemisation
• Demand for more than 30 % deposit before start
• Warranty shorter than 2 years on workmanship

Service calls on existing floors:

• Screen and recoat (light sand + one top coat, no full sand) is €14–€22/m², adds 3–6 years to a tired finish without a full refinish
• Spot repair of a 1 m² damaged zone: €180–€380 labour
• Isolated plank replacement: €35–€70 per plank + labour
