Mold growth is often caused by moisture, organic residues, or poor ventilation. It severely damages building materials and poses a significant health risk. Especially in sensitive areas such as food production facilities, archives, public buildings, or residential spaces, thorough, controlled, and residue-free removal is essential. Since the affected surfaces (wood, concrete, natural stone) are often already weakened by the fungal infestation, an extremely gentle treatment of the material is mandatory.
Traditional methods (such as chemical treatments, fungicides, or high-pressure cleaning) have major disadvantages. While chemicals kill the fungus, they often leave toxic residues soaked into the material. High-pressure washing disperses spores into the air, introduces additional moisture into the surface, and can further damage the structure. Mechanical removal (sanding, brushing) is time-consuming, imprecise, and promotes cross-contamination of the surrounding environment.
Laser cleaning removes mold 100% dry, with absolute precision, and entirely without chemical additives. The laser beam thermally vaporizes the spores and fungal mycelium deep down to the roots, without introducing moisture or damaging the underlying surface. The result: a perfectly remediated, disinfected, and residue-free zone. This drastically reduces renovation times, minimizes the risk of immediate regrowth, and fully preserves the integrity of the original material.

Yes, the laser energy thermally destroys spores and mycelia right at the root, even in micropores and micro-cracks of the material.
No, the precise settings of the laser allow it to target only the fungal layer. The base material (wood, stone, concrete) reflects the light and remains completely intact.
Absolutely not. No chemicals are used. The vaporized particles are immediately extracted at the source and safely trapped in H-class industrial filters.
Yes, it is the safest method for interiors. Without the use of toxic fungicides or additional moisture, the rooms can be safely occupied immediately after treatment.
The laser sanitizes the surface perfectly. However, to prevent long-term recurrence, the underlying structural cause (leaks, thermal bridges, rising damp) must of course be resolved.
