Technical building inspection is no superfluous luxury

Anyone who is about to buy an existing home would do well to have it inspected from a building technical point of view. This not only makes it clear whether and which defects the house has, but also what the costs are to deal with them. But is an inspection also necessary for renovated oldies?

A broken sewer system, a leaking roof, wood rot… It will only happen to you: when you have just bought your dream house, it turns out that everything is wrong.

Price tag

To prevent you from being faced with unpleasant surprises, it is wise to have a building inspection carried out. An extensive inspection that looks at the condition of the house and the possible price tag attached to the improvements.

The results also make it easier to decide whether you really want the house and at what price.

The inspection examines, for example, the quality of the roof, window frames, floor and boiler. To the overall picture, says John Kersemakers of Vereniging Eigen Huis. For example, the inspector does not investigate where a leak comes from. If we see strange cracks in the house whose cause is not immediately clear, we advise you to call in the help of a specialist

If defects are identified during an inspection, the costs of repairing them are also mapped out. A distinction is made between direct and indirect costs.

Kersemakers: The direct costs are the repairs that have to be done within a year, such as grouting or roof tiles that need to be replaced The indirect costs are about things that need to be done within three to four years. Replacement of the boiler, for example, which lasts for an average of around eighteen years

The study also looks at the so-called housing improvement costs. A prospective buyer can indicate that he doesn‘t like the pink tiles in the bathroom and wants to know what it costs to replace them


The older the house, the greater the chance of defects, of course. Even in the case of an old property that has been completely renovated, it is advisable, according to the Eigen Huis Association, to have it inspected. After all, you don’t know by whom the work was carried out. By a skilled contractor or a hobbyist? Kersemakers warns: During a renovation, a building may have been cosmetically refurbished to conceal defects

Such research pays off not only for potential buyers, but also for sellers. Certainly in regions where houses are less likely to be sold than in the Randstad, says Kersemakers.

According to the expert, it saves a lot of time and negotiation problems when you can tell interested parties exactly what the defects and possible costs are and that you have based your asking price on them.
