The true financial impact of building defects is often misjudged without an appraiser. A surveyor helps you to protect your capital and property by making a technical assessment of the situation. We will show you the costs that you have to expect for the assessment and the preparation of written versions.

Many people shy away from the expense of hiring a surveyor out of fear. They fear that the expenditure is out of proportion to the benefit. This fear must be contradicted, however, because the risks are high when buying a house without experts. If structural defects are detected too late, high follow-up costs can arise. On the other hand, there are calculable and relatively cheap expenses for the construction expert. If you do not need a written version but only information about the existing defects, then the costs are reduced.

Labor costs: 70 Euro / hour x 2 hours = 140 Euro
Travel expenses: 5 percent x 140 euros = 7 euros
Expertise: 40 Euro / page x 10 pages = 400 Euro

Important questions

How can I keep costs low?>

Tip: Check whether in the event of legal disputes a cost assumption by the legal expenses insurance is possible.

Who has to pay the costs for the construction expert?

As a general rule, the person who hires the surveyor must bear the costs. However, it is possible to obtain reimbursement by other parties. First of all, the client is obliged to pay the agreed final fee to the expert. If it is determined by a court that the opposing party must pay the full amount or a partial amount, the costs will be reimbursed. In some cases it is also possible to obtain a provisional reimbursement of costs from the own legal expenses insurance if the expert opinion is required for a legal dispute. For example, if there are structural defects caused by a construction company, the commissioning of the construction expert often takes place within the framework of a legal dispute. However, if the report is needed before making a purchase decision, then the potential buyer usually appears as the client.
