Who we work for

Building expert for property managers

Establishing the origin of a defect in a building and drawing a clear line between common and private parts.

  • Independent expert
  • Report you can use with your insurer, your contractor or the court
  • Site visits throughout Luxembourg

Our role beside you

In a multi-unit building, a defect is rarely a purely technical matter. It affects several units, commits a shared budget and awaits a decision of the owners' meeting. Without an established cause, the discussion goes in circles.

We work with property managers in Luxembourg to establish the origin of defects and state what each repair belongs to. Our position is independent of both owners and contractors.

You then hold a neutral document that lets you present a reasoned budget to the general meeting and pursue a claim where needed.

Situations where we step in

  • Water damage between two units: locating the real entry point and setting the boundary between common and private parts.
  • Cracks in façades or stairwells: qualifying the defect and assessing its progression and structural risk.
  • Roofs and terraces: condition of the waterproofing, upstands and drainage, with the repairs to schedule.
  • Basements and garages: rising damp, infiltration through buried walls, corrosion of reinforcement.
  • Poorly executed works: checking a contractor's work before the final payment and support in case of dispute.

How the assessment works

01

Defining the brief

We agree the scope with you, the units concerned and the documents to gather: drawings, works history, earlier reports.

02

Building inspection

Findings in the common parts and, with the occupants' agreement, in the units affected.

03

Analysis

We establish the cause, its exact location and the technical responsibilities, including those of a contractor who worked before us.

04

Report for the meeting

You receive a report suitable for the general meeting, with priorities and an estimate of the works.

The expert report

The report states clearly what belongs to the common parts and what belongs to the private parts, a condition for an uncontested allocation of charges.

It proposes a ranked programme of works: urgent measures, repairs to budget and points that simply need monitoring over time.
