Once the location, the extent and any damage has been ascertained, it is possible to estimate how much it costs to fix an infiltration by requesting a quotation from several companies or specialized professionals, in order to choose the best offer.
The costs of the intervention may vary depending on where the infiltration is located and/or the damage has appeared. Infiltrations may concern:
- outer walls;
- doors and windows.
In the case of roofs, waterproofing is often necessary. The cost, depending on the intervention required, can range between € 17 and € 100 per square meter for more complex jobs, including labor.
If the infiltration is in the floors, the fixing costs are higher (and can reach up to € 300 per square meter) because, in addition to waterproofing, it is very often necessary to replace the pipes.
Fixing an infiltration on the outer walls requires the application of a liquid membrane which costs approximately € 10 per square meter upwards.
These costs are absolutely variable, depending on the geographic area and also on labor costs.
For this reason, before accepting a quote, it is advisable to compare multiple offers and choose the one that guarantees the best value for money and lead times.
