Diagnostics, repairs, expertise

and technical reports

Pathological expertise of

houses and buildings

We carry out technical expertise (defects, poor workmanship, hidden defects) of houses and buildings that make them unsuitable for habitation, even dangerous! We will allow you to take legal action before the Swiss Courts in the event of bad faith by an ex- owner, a real estate agency, a construction company or a construction’s independent worker. You have bought a property and you think you have made a good deal, but you discovered after the purchase problems of cracks, water leaks in a wall, infiltration during heavy rains, tiles that come off and perhaps more than you haven't seen? You don't know yet what surprises you are going to have and only an experienced professional can find out by diagnosis and estimate the repair work. In the meantime you will sleep at the hotel or temporarily rent an apartment during the works. This generates costs not foreseen before the purchase. Are you a victim of fraud? (a false sale)?

Property inspection

We seek to identify the technical problems of a property which reduce its use, its value or which present a risk to the safety of the occupants. We will provide you with a detailed inspection report and proposals for remediation or replacement of defective items.

Pre-purchase inspection of a property

Used real estate The pre-purchase inspection allows you to know the current physical condition and the real value of a property, but also to know what the costs of repairs (water infiltration, insulation, etc.) and compliance will be. mandatory (electricity, heating, asbestos, etc.) as well as the maintenance budgets that will help keep your future property in good condition. Our budget data will help you negotiate the purchase and financing of your property. The pre-purchase inspection serves to protect you in the event of hidden defects that may arise after the real estate transaction. It will allow you to negotiate, buy or abandon the real estate project for another more interesting opportunity. Our   goal   is   to   protect   you   and   reassure   you   of   the   purchase,   then   to   inform   you   about budgets   for   renovations   and   energy   efficiency   improvements.   Real   estate   is   ultimately   a long-term financial matter.

Preventive inspection of a property

Used real estate Preventive inspection is used to know the condition of a property to keep it in good condition and even increase its market value before it is put up for sale. This avoids unpleasant surprises which can be costly, by making repairs or maintenance too late. This service represents an investment to maximize a property and protect against possible claims for latent defects.

Pre-acceptance inspection of a property

1) New property. Hidden defects and poor workmanship are very common in new constructions. Water infiltration in semi-buried spaces or cellars, cracks in walls, cracks in ceilings, cracks in floors in new constructions are the most widespread defects. The pre-reception inspection will allow you to see in time to inform the manufacturer of the important corrections to be made with the warranty for defects. 2) Used and renovated real estate. The pre-acceptance inspection will allow you to know the current condition of the property and check that all the work has been carried out in compliance with the standards in force.

Hidden defect expertise after the purchase of real


House or other real estate purchased without inspection. This type of inspection takes place after the new owner moves into their new home and after a few days discovers the first anomalies. Once there, the bad smells persist despite the cleaning, the noise of certain tiles which are gradually peeling off, a crack appears on a corner and progresses, mold appears on certain places which were clean, the paint is peeling off, infiltrations of water appear, etc. Hidden defect Features: The hidden defect is not seen during the discovery tour of the house. The hidden defect is concealed by the former owner, because he does not consider it serious. The real estate agent who takes care of the sale often ignores it, because he is not informed. This hidden defect, but announced to the buyer, would have allowed a fair negotiation of the sale price to compensate for the costs incurred to put this problem in order with qualified craftsmen. The discovery of the hidden vice, after the real estate transaction by the new owner, is not pleasant. The    simplest    and    most    economical    solution    is    to    find    an    amicable arrangement   between   the   former   owner   and   the   new   owner,   so   that   the   former owner participates in the cost of repairs and compensation. In the case of a solution by the courts, the former owner risks a lot, because the conviction gives rise to administrative costs, repair costs and compensation costs which are much higher.
