Façade renovation: decisions at each stage

Gather drawings, photographs, earlier repairs and signs of moisture or cracking. Define assessment scope and inaccessible areas. Choose retention, refinishing or insulation after that assessment; faded colour alone does not establish a need for complete renovation.

Discuss appearance changes and work with the municipality; Guichet.lu describes the permission framework for alterations. Clarify access, possible public-space occupation and building constraints. Where insulation is included, prepare grant paperwork before the relevant work too.

Buildwise’s NIT 296 introduction relates cleaning to material, dirt and wall condition, with trials and protection of neighbouring surfaces. Request a trial area and expected result. High pressure or abrasive blasting should not become an automatic method for every façade.

Have repairs and substrate condition checked before covering. For render on insulation, Buildwise distinguishes substrate checks and handover. Request the actual system instructions and drying conditions rather than a uniform waiting period from a guide.

Agree a colour sample, expected appearance and details around windows, sills and plinths. Specify protection, temporary opening restrictions and effects on ventilation or access. Continued occupation must be organised with the contractor, not assumed to be unaffected.

Compare completed work with the quote: treated areas, finishes, junctions and reinstalled components. Record reservations and follow-up. Keep product references, useful photographs, invoices and maintenance instructions. Ask about relevant commitments and insurance rather than assuming one warranty covers every finish.
