Treating damp in walls: all costs listed

You discover moisture in your walls and want to have it treated professionally: what are the costs? And how do you choose the right company specializing in damp control? It is helpful to know how a damp control firm calculates the total costs to tackle moisture problems. This way, you can understand quotes more easily and compare prices. We provide expert guidance.

Different types of damp in walls, different prices

When it comes to damp proofing and the associated costs, the cause of the damp problem is often the deciding factor. For example, is it rising damp, penetrating damp, or condensation? The larger the damp problem, the higher the costs often rise. It is therefore best to act as quickly as possible.

Suppose a damp proofing company determines that there is rising damp. In that case, wall injection is a frequently chosen option. Is the wall already severely damaged? Then it may be necessary to replace the plaster as well. You can then expect an average total price between €1,000 and €2,000 for a 10-meter wall – although this price can fluctuate significantly depending on the type of damp-proofing gels or other liquids a company uses when injecting and finishing walls.

With penetrating damp, the total price is often higher because more work is required to repair the walls. It is usually necessary to treat the entire facade with a water-repellent agent so that the damp problem disappears for good. Depending on the surface, one or more exterior layers are needed to optimally protect the walls.

Damp proofing for walls: other factors that determine the price

In addition to the cause of the damp problem in walls, there are also other factors that determine the final price. For instance, the accessibility of the wall influences the price calculation – because a wall that is difficult to reach requires more work and time.

Furthermore, the type of home is also important. Do you have an older home? Then you may be dealing with a poorly functioning damp-proof course, which can make the treatment more complex.

Finally, the finish plays an important role. Depending on the state of your walls, additional work is often required, such as facade cleaning, repointing, and ventilation. A damp proofing company is your priority to ensure dry walls before you think about facade cladding or insulation, for example. Some companies can also finish your facade to perfection – so it’s good to keep this in mind when looking for the ideal company to treat your walls.

Damp proofing: are you entitled to a grant?

For damp proofing, you are entitled to one or more grants if you meet a number of conditions. One of the most important grants is the ‘Mijn VerbouwPremie’ from the Flemish Government. If your home is older than 15 years, you may qualify for this grant. The amount you receive depends on your household income and the nature of the work. In some cases, up to 50% of the costs are reimbursed. Want to view all grants immediately?

Company specialized in damp proofing: how do you make the right choice?

You always win with the right advice. That is why most specialized companies start with a no-obligation inspection or diagnosis. They come to your home to assess the situation and analyze the damp problem – usually using a moisture meter to check how deep the moisture is in the walls.

Afterwards, they determine which type of damp is causing the problem and advise you on the best solution. You will then receive a quote with an overview of the work, the materials required, and the total cost.

Do you agree? Then they schedule the execution of the work. Depending on the scale of the problem, this usually takes one to several days. Many companies also offer some form of aftercare or guarantee, so you can be sure that the damp problem has truly been resolved.
