Black spots on the walls, musty odors, mold behind furniture or in corners. Mold always comes from a moisture problem.

Fungi in the basement or crawl space

Mushrooms growing on wooden joists, the smell of damp earth, rotting wood. These are signs that moisture is not being controlled.

In many cases, this happens in the homes of Lévis with a poorly ventilated or insulated basement.

Asbestos in old materials

Many houses built before 1990 contain asbestos—in insulation, floor tiles, textured ceilings. It is only dangerous when damaged or disturbed, but it must be handled properly.

Poor insulation

Poorly insulated attic, cold walls, thermal bridges, drafts. The result: high heating bills, an uncomfortable home, and condensation that creates humidity.

Poor insulation can also affect other renovations, such as bathroom renovation or kitchen renovation.

Damage after a loss

After water damage, a fire, or flooding, contaminants, soot, and trapped moisture often remain. If not cleaned properly, this can cause long-term problems.

In some cases, reconstruction also includes basement finishing.

Inadequate ventilation

Not enough air exchangers, dirty ducts, stale air that doesn't circulate. This concentrates pollutants and humidity in the house.

Inadequate ventilation can also create problems, as explained in attic ventilation: why it's crucial for insulation in Lévis.

Contaminated vermiculite in the attic

Old vermiculite insulation (gray granules) that may contain asbestos. Must be removed with caution.

In such cases, it's often necessary to completely re-insulate the attic.

Frequently Asked Questions

Is all mold dangerous?

All mold can cause health problems, especially for sensitive individuals (children, seniors, people with respiratory problems). Some molds are more toxic than others, but no mold should be allowed to grow in your home. All mold must be removed.

Can mold be cleaned with bleach?

Bleach kills mold on surfaces, but does not penetrate porous materials such as drywall or wood. Worse still, it does not address the source of moisture. The mold will return. For permanent decontamination, contaminated materials must be removed and the cause corrected.

How can I tell if my house contains asbestos?

The only way to know for sure is to have a sample tested in a laboratory. Houses built before 1990 are more likely to contain it. If you have any doubts before renovating, we can do a test. It costs around $50-100 per sample.

How long does mold decontamination take?

For a small area (closet, bathroom corner), 1-2 days. For an entire basement, 3-5 days. For major cases involving several rooms, a week or more. It depends on the extent of the problem.

Do I have to leave my home during decontamination?

Not necessarily, if the work area can be effectively contained. But if it's a major decontamination or asbestos removal project, it's often recommended that you leave for a few days, especially if you have children or respiratory problems.

How much insulation is needed in attics in Quebec?

The building code recommends a minimum of R-40, but we recommend R-50 to R-60 for our climate. The more you insulate, the more you save on heating. The investment pays for itself in energy savings.

Is blown insulation as good as panels?

Yes, even better in some cases. Blown insulation (cellulose or fiberglass) fills all corners, cracks, and spaces—no thermal bridges. It's our preferred method for attics.
