Moisture problems in new-build homes
In any building, moisture can occur at some point. In many cases, this remains almost harmless, such as the occurrence of condensation moisture after showering. However, over time, even seemingly minor moisture problems can cause damage. Read all about moisture problems in new-build homes here.

What moisture problems in new-build homes?
Different types of moisture problems the head in a new-build home. We list some common causes of damp problems in a new building.
Building moisture
Moisture problems in new-build homes are often caused by building moisture. Building materials such as cement and concrete require a lot of water during production. In addition, weather conditions during the works can also cause additional moisture. After construction, it is essential that these materials are given sufficient time to dry out properly before the property is occupied. Adequate ventilation is also required. However, we often find that this is not always respected in practice, which can result in increased humidity or moisture stains. So wait a sufficient amount of time and ventilate your newly built home thoroughly before finishing your walls and floors and moving in, otherwise you will suffer from moisture problems in the long run.
Condensation moisture
In humid rooms such as kitchens and bathrooms, humidity rises quickly. When you cook or take a bath, a large amount of water vapour enters the air, which will then deposit on cold surfaces, such as the walls and ceiling. The resulting water droplets are harmless at first. However, it becomes a problem when the humidity is too high for a long period of time and the water vapour cannot escape. This type of condensation problems is often caused by mistakes in construction or faulty insulation installation.
Rising damp
Rising damp occurs when walls absorb soil moisture or excess rainwater. This phenomenon is often caused by high groundwater levels and can be exacerbated by problems with the flood defence. Failure to do so when renovating the waterproofing is one of the most common construction mistakes that lead to this moisture problem. Allowing plaster to reach the ground can also contribute to rising damp.
Consequences of moisture problems in new buildings
Moisture problems in a new building have adverse effects on both the liveability and the value of the new home:
The longer symptoms are ignored, the more difficult and expensive treatment becomes. So it is essential to address moisture problems early, even if they only occur in winter.
Tackling moisture problems in your new home
Just as there are different causes for moisture problems, there are also different moisture solutions that can remedy moisture problems. Some examples are:
The best solution to deploy depends very much on the cause and extent of the moisture problem. Make sure you call on the expertise of a moisture expert, as this ensures the right choice and correct application of moisture control methods.

How do you get moisture out of a newly built house?
The moisture in your new-build home won't just go away by turning up the heating. In fact, it can cause the moisture problem to get worse every day. The most effective solution is the combination of constant ventilation and letting the moisture in the house dry out. It is a process that involves a lot of patience combined with the right technique. Now, during the construction of your home, litres of water are used for concrete and plastering. Modern homes are airtight, which means that the building moisture has nowhere to go, resulting in high humidity levels.
Waiting for it to go away on its own carries risks, as untreated moisture gets worse every day. For instance, it can affect the construction of your house and mould can develop. Prevent further moisture damage to your newly-built home by investing in stable heating and mechanical ventilation in time. But only by tackling the underlying moisture problem at the source will you protect your new investment and the health of your family.
Is it normal to get mould in a newly built house?
With a new home, you expect a fresh start, yet mould is present in a lot of new, modern homes. This moisture problem is more common than thought. This is because the constructions of new buildings are airtight, so daily condensation no longer finds a way out, not in the natural way anyway. Mould spores only need a damp wall and stagnant air to develop quickly on your new plastering. Don't ignore this moisture problem, as untreated moisture will only get worse and affect the finish of your entire home in no time.
Prevent further damage to your newly built home from the moment you notice black spots or a musty smell in the house. Merely brushing away the mould is never a solution. The mould will simply return as long as the source of the moisture problem is not addressed.
Is moisture common in new-build homes?
The answer is ‘yes’. Almost every new home suffers from moisture problems, mainly the persistent presence of building moisture. Lots of gallons of water are used during the construction process, and because houses are airtight and superbly insulated, the moisture cannot escape. Or at least not in a natural way. From the moment you move into your new home and use heating, moisture migrates into the walls and ceilings. This can lead to a clammy indoor climate. Waiting for the problem to solve itself is not an option, as the moisture gets worse every day, threatening your family and interior.
Is housing construction responsible for mould?
Whether the construction of the house, and therefore the contractor or construction promoter, is responsible for mould depends very much on the cause. Is it a construction defect or residual building moisture? In new construction houses, a technical defect in the water barrier or a thermal bridge may be the cause of the moisture problem. If this is the case, it falls under the ten-year liability of housing construction. But if the mould is caused by a poor form of ventilation or insufficient drying of building moisture, it is often more difficult to prove that it is effectively due to the construction of the house.

Frequently asked questions about moisture in new-build homes
Yes, excessive humidity in your home has a direct impact on your health. When building moisture or condensation moisture cannot get away, moisture and additional fungus builds up. This can lead to respiratory irritations, asthma and allergies. Especially in modern new-build homes, polluted air lingers causing the moisture problems. So don't wait until you experience health symptoms to deal with the moisture problem, because moisture gets worse every day and as you are exposed to it, the health risks increase. Also, prevent further damage to your newly built home by taking action immediately at the first musty smell you smell and a free diagnosis to be requested from AquaConsult.
For new-build homes in Flanders, this involves the ten-year liability from the contractor or construction promoter for serious defects that endanger the stability of your home. For hidden defects that were not immediately visible upon completion, you need to act quickly as soon as you discover the (moisture) problem. Quick action is important not only for liability, but certainly also for the moisture problem, because moisture is getting worse every day. Have the problem diagnosed by AquaConsult to strengthen your legal position. This way, you also immediately prevent possible further damage.
The main cause in new construction houses for moisture is usually residual building moisture that was not drained in time. In addition, a poorly adjusted ventilation system, windows being sealed too quickly or unforeseen leaks in the water barrier can also cause major moisture problems. Whatever the cause, prevent the moisture as soon as possible to protect your home. Have the source of the moisture problems in your new-build homes identified by one of our experts.
Sure! A humidity of 70% in the house is way too high. The ideal value of humidity in a new building is between 40% and 60%. A higher percentage indicates insufficient ventilation or that residual moisture is still present in the walls. This gives moisture and mould free rein, and knowing that moisture is getting worse every day means that it can quickly lead to condensation on the windows and walls and, in the long run, health problems as well. Prevent further damage to your home and your health with AquaConsult bringing the humidity in your home to safe levels with quality ventilation systems.
