When is professional surface disinfection necessary after repair or renovation work?

After repair or renovation work, premises may appear visually clean, but in reality they often remain contaminated with dust, chemicals and microorganisms . Such an environment can pose a health risk, especially if children, seniors or people with allergies live in the premises.

Therefore, professional disinfection of surfaces after repairs is not a luxury - it is a necessary step to restore a safe and hygienic environment.

What are the dangers of premises after renovation?

During repairs, the following is deposited in the air and on surfaces:

  • construction dust (cement, plaster, concrete);

  • mold spores that become active when walls are damaged;

  • chemicals from paints, varnishes, glues;

  • bacteria and microorganisms that have entered through old structures.

These particles can remain in the air and on surfaces for a long time, even after thorough household cleaning.

When is disinfection particularly recommended?

Professional disinfection is necessary if:

  • old walls or floors were demolished;

  • the premises previously contained mold or moisture;

  • the renovation took place in an old building;

  • planned use of children's room, kitchen or medical premises;

  • repairs were made after a flood or fire.

In such cases, cleaning alone does not remove invisible contamination.

How is professional disinfection different from simple cleaning?

Household cleaning:

  • removes only visible dirt;

  • does not reach bacteria, spores and chemical residues;

  • has no long-term effect.

Professional disinfection:

  • kills bacteria, viruses and fungi;

  • neutralizes odors;

  • reaches hard-to-reach places;

  • creates a safer microclimate environment.

How is professional disinfection performed?

The most commonly used methods:

  1. Cold fog disinfection – the disinfectant is dispersed in microparticles.

  2. Ozonation – destroys microorganisms and odors.

  3. Surface treatment with biocidal products .

  4. Air disinfection is especially important after painting or varnishing.

The method is selected based on the condition and purpose of the premises.
