Façade budget: compare quotations item by item
Published on 31 July 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
No Luxembourg average calculated from documented quotations is presented here. Start with assessment and compare equivalent work: treated area, support condition, access, finish and possible insulation. This guide helps explain differences without presenting fictional examples as observed prices.
The essentials in 30 seconds
- Give each contractor the same defined brief.
- Ask how areas and openings are measured.
- Separate preparation, finishes and insulation.
- Check access, protection and related repairs.
- Do not count unconfirmed grants as secured funding.
Define what the budget covers
Distinguish cleaning, repainting, render renewal, cladding and complete insulation. Buildwise describes several external insulation systems; visible material alone does not define them. Specify the build-up before comparing offers.

Compare quantities
Ask how façades are measured, whether openings are deducted and how reveals, sills and plinths are counted. Align measurement conventions. Do not universally deduct windows while overlooking perimeter work.
Read support preparation
Identify cleaning, removal, repairs, crack assessment and moisture-cause treatment. Specify retained areas. Limited preparation and extensive renewal need their findings and exclusions clarified before comparison.
Include associated work
Check scaffolding, protection, access, removal and reinstatement of downpipes or equipment, sill changes and finishes. Ask about waste and final cleaning. Where scaffolding serves several trades, confirm actual sharing and who coordinates its use.
Your project deserves an accurate estimate — it's free.
Request a quotePlan for unknowns and changes
Ask which findings could trigger extra costs and how these are priced and approved. Separate options from required work. A low offer does not prove hidden items, but missing lines need clarification before signing.
Separate price and funding
Guichet.lu describes conditional energy-renovation support; an estimate is not payment. Show total cost, scheduled payments and confirmed grants separately. Check additional schemes with their providers rather than deducting a standard percentage from every façade project.
Frequently asked questions
Which area rate should I use?
One from a defined quotation for your wall, with its measurement basis and services. No unobserved local average is published here.
Should every window be deducted?
Ask about measurement conventions and perimeter work. Compare matching quantities and services.
Is a cheaper offer suspicious?
Not from its total alone. Clarify scope, preparation, products, quantities and exclusions.
Does insulation make the whole renovation subsidised?
Not automatically. Check the application and relevant expenditure before including support.
Can coordinated work save money?
Request an offer identifying genuinely shared access and services. No fixed saving is guaranteed.
