How long does it take to do a real estate diagnosis?
In order to carry out a real estate diagnosis, the expertise of a generalist or specialist is necessary. This expert will then examine the condition of the building by taking into account a number of criteria or indicators.
Before a sale, the law obliges the realization of a diagnosis, the place of the good, the nature of the transaction and the date of construction will make it possible to fix the number of diagnosis to be carried out.
A property whose building permit was obtained before January 1, 1949 requires several diagnoses as:
- The state of natural, mining and technological risks.
- Checking for the presence of lead.
- Control of the electrical installation.
- Diagnosis of the presence of asbestos before sale.
- Diagnosis of energy performance.
There are no rules regarding the rate framework. The price of the diagnosis is freely fixed by the diagnostician, criteria such as the surface and the location of the property influence the cost of the diagnosis.
The time spent on a real estate diagnosis depends on the type of expertise to be carried out, the size and the technicalities of the property.
Have you asked yourself the question: Is it possible to sell your home without real estate diagnostics?
The 3 steps of a real estate diagnosis
- The first contact
The first contact: When you request a quote, an appointment is scheduled to explain the estimate, but also in order to provide the necessary documents for the real estate diagnosis.
- The beginning of the intervention
The purpose of the intervention is to verify information such as the number of lots in co-ownership or the cadastral reference of the property. Energy bills, work invoices and plans are documents that will be reviewed for the start of the intervention.
- The first location
The purpose of this step is to get an overview of all the rooms that make up the property. A description of the property will be made listing all the elements such as walls, windows, floors or ceilings, etc. Then, the various diagnoses will be able to begin, it is necessary to count on average 1 hour to carry out a real diagnosis.
The different real estate diagnostics
- DPE energy performance diagnosis
The purpose of the energy performance diagnosis is to measure the amount of energy used by the property, as well as the greenhouse gas emissions generated.

We hear about the Carrez law and the Boutin law when it comes to measuring the surface of a property.
The Carrez law concerns housing located in co-ownership, during a sale the Carrez law surface is a mandatory information. As for the Boutin law surface, it corresponds to the living area of a dwelling. Unlike the Carrez law, garages, cellars, verandas or attics are not taken into account. The Boutin law must therefore be indicated for residential housing.
The diagnosis costs on average between 80 € and 150 €. Calling in a professional means you won't incur civil liability in the event of a dispute, so the length of his or her intervention will depend on the surface area to be diagnosed.
- Lead diagnosis, CREP
The lead diagnosis or lead exposure risk report is the most time consuming diagnosis. The professional who carries out the intervention must control the presence of lead on all the constituent elements of the property as well as on the external elements which can contain some like for example:

- The portal
- The shutters
In case of presence of lead, the technician will be obliged to transmit a copy of the report to the regional health agency depending on the property. The price of the diagnosis varies between €100 and €250, and the time required to carry it out can range from 30 minutes to 5 hours, depending on the surface area of the property.

The duration of intervention of real estate diagnostics
Each of the diagnoses can take a certain amount of time to complete, so it is difficult to give a precise time to complete a property diagnosis.
For small apartments, they can be completed in just a few hours, while for large apartments or houses it can take several hours.
It is important to specify that the duration of a diagnosis depends on several factors such as the surface area, the age, the general condition and the nature of the property. It is preferable to ask for an estimate from a real estate diagnostician in order to have a more precise estimate.
The time it takes to carry out real estate diagnostics depends on several factors:
