Damp control costs an average of 300 to 8,000 euros, depending on the cause, severity and the solution used. From a simple moisture measurement to complete basement waterproofing. Discover all costs here.
Average cost for a moisture control specialist (average)
Moisture control includes all work to structurally solve moisture problems in and around a home. This may involve rising damp through the walls, condensation, leakage or ground moisture in crawl spaces and basements. A moisture specialist first makes a diagnosis via a moisture measurement and then recommends the right solution. Untreated moisture problems lead to mold formation, wood rot and an unhealthy indoor climate.
Rising damp is combated by injecting the walls. A moisture-resistant agent is injected into the wall to serve as a barrier. This costs 50 to 120 euros per linear meter. Condensation problems are solved with better ventilation, for example a mechanical ventilation system (1,500 to 4,000 euros). In case of ground moisture in the crawl space, drainage is installed or a damp-proof foil is applied.
Waterproofing a damp basement is an intensive job. Depending on the method, basement waterproofing costs 150 to 400 euros per m2. Methods include applying a waterproof coating, injecting cracks and installing drainage. A complete basement waterproofing for an average basement of 20 m2 costs 3,000 to 8,000 euros. After treatment, the basement can be used as a living space or storage space.
Moisture in the crawl space causes a damp floor, mold odor and higher heating costs. Installing crawl space ventilation costs 800 to 2,000 euros. Ventilation openings and possibly a mechanical system are installed. Combination with ground insulation (15 to 30 euros per m2) tackles the problem sustainably and noticeably improves living comfort.
Contact a moisture specialist immediately if you have damp spots on walls, a musty smell, condensation on windows, peeling wallpaper or visible mold. The longer you wait, the bigger and more expensive the problem becomes. An early moisture measurement only costs 100 to 250 euros and provides immediate insight into the cause and the required solution.

| Mechanical ventilation | €1500 | €4000 | per system |
Rising damp, condensation, leakage and ground moisture each require a different approach with associated costs.
A minor moisture problem is cheaper to solve than years of neglect resulting in mold and wood rot.
The more walls or floor space that needs to be treated, the higher the total costs.
Hard-to-reach crawl spaces or basements increase labor costs due to limited work space.
A professional moisture measurement with advisory report costs 100 to 250 euros. Some damp control companies offer a free inspection if you have the work carried out.
Signs are damp spots on walls, peeling wallpaper, a musty smell, condensation on windows, white efflorescence on walls (lime efflorescence) or visible mold. If in doubt, have a moisture measurement carried out.
Wall injection is the most commonly used method. A moisture-resistant agent is injected into the wall to serve as a barrier. This costs 50 to 120 euros per linear meter and is effective for most home types.
A wall injection for an average home takes 1 to 2 days. Basement waterproofing can take 3 to 5 days. After treatment, the moisture still has to evaporate, which can take weeks to months before the walls are completely dry.
