Cold Room Mold Removal
Basement cold rooms are among the most mold-prone spaces in Quebec homes — poor airflow, concrete walls, and year-round humidity create conditions that almost guarantee growth over time.
Cold rooms — the uninsulated storage spaces found in most Quebec basements — are built to stay cool, but their design makes them inherently vulnerable to mold. Concrete walls absorb and hold moisture, air circulation is minimal, and temperature fluctuations between seasons cause repeated condensation cycles.
Mold in cold rooms is often visible as dark patches or white powdery growth on walls, shelves, and stored items. It can develop quickly and, if connected to the home's ventilation, affect air quality throughout the house.
Our cold room mold treatment includes a full assessment of the affected surfaces, mechanical cleaning and biocide treatment, and a moisture management review. We'll identify whether improved sealing, ventilation, or drainage is needed to prevent recurrence.
If mold has spread to joists, subfloor materials, or adjacent walls, we address those areas as part of the same job. Every treatment is documented with a written report and before/after photography.
Common Questions
Why is my cold room getting moldy every year?
Recurring mold in cold rooms usually comes down to persistent moisture — either from condensation on cold concrete surfaces, water infiltration through the foundation, or high basement humidity. Treatment alone won't prevent recurrence without addressing the root moisture source.
Is cold room mold dangerous?
Yes. Many mold species found in cold rooms can trigger respiratory symptoms, allergic reactions, and in some cases more serious health effects with prolonged exposure. Cold rooms connected to main living areas can distribute mold spores throughout the home.
Can I just bleach it myself?
Surface bleaching will temporarily kill visible mold but won't penetrate porous concrete or address the underlying moisture problem. Professional treatment uses appropriate biocides and physical removal to eliminate the colony properly.
Do you treat the shelves and items inside?
We treat all affected surfaces within the cold room. Wooden shelving, stored items, and any visible mold on walls and ceiling are all part of the scope. Severely moldy items may need to be discarded.
