Common questions

Answers

What damage does Litscher GmbH investigate?
Litscher GmbH specializes in expert reports on construction, root-cause analyses, and professional remediation solutions for mold, moisture, and water damage. The range of services is complemented by odor neutralization, disinfection and hygiene solutions, as well as expert consultation and training. As the general representative of Sanosil Schweiz for German-speaking Switzerland, Litscher GmbH combines many years of practical experience with professional products and application solutions.
How is leak detection performed?
Leak detection is carried out as non-destructively as possible, for example on water, heating and drain pipes or on flat roofs and terraces. Depending on the situation, smoke gas, ultrasound, fogging methods or other inspection methods are used.
Who are the services particularly suitable for?
The services are aimed at companies and private individuals, especially at insurance companies, real estate firms, administrations and associations. Property owners of residential buildings and apartments also benefit from the clarifications and renovations. Also specialized trades and commercial customers who require professional disinfection, cleaning and hygiene products from Sanosil AG benefit from product guidance and sales through the General Agency Sanosil Switzerland.
What does a mold diagnosis or mold assessment include?
A mold diagnosis can include spore measurements, room climate measurements, and microbiological analyses. You will then receive a detailed report with the measurement results and a professional assessment.
Which Sanosil products are suitable for mold suppression, odor control, or after water damage?
For mold and water damage, Sanosil SD7 (silicone-free) and Sanosil S010 (with silver) are suitable. Sanosil QDis 8 as well as Sanosil S015 are suitable for aerosol/room disinfection. For hard-to-reach cavities, Sanosil SFS can be used with S015. For general surface disinfection, the products Sanosil S003, SanoClean AR and Sanosil SD1 are suitable. For odor control, the products SanoSorb PX, Longactive and especially for drains the Multi-enzyme L from Felema are suitable. The Litscher GmbH uses these products professionally.

Which disinfectants are suitable for mold infestation?

At Litscher GmbH we repeatedly see the same pattern in practice: those who choose the product first, instead of clarifying the infestation and moisture situation, end up treating only symptoms. Therefore, in products for mold remediation, the order is more important than the name on the bottle. This surprises many people, because the obvious instinct is to reach for the cleaner, although it does not effectively remove spores, germs, and viruses.
