Types of mold we remove in Ottawa
Black mold (Stachybotrys)
Toxic black mold is one of the most dangerous for health. It develops on cellulose-rich materials like drywall, wood and wallpaper when exposed to prolonged moisture. This mold produces mycotoxins that can cause serious respiratory problems, chronic headaches and severe allergic reactions. Our certified technicians use complete containment and HEPA filters to safely eliminate all spores.
Mold after water damage
Floods, sewage backups and water leaks create ideal conditions for rapid mold growth within 24 to 48 hours. Ottawa’s climate with its freeze-thaw cycles promotes water infiltration in spring. We respond quickly to dry, decontaminate and treat affected areas before mold spreads throughout the structure.
Basement and crawl space mold
Ottawa basements are particularly vulnerable to mold due to high humidity, condensation and groundwater infiltration. Mold develops on foundation walls, insulation, wood beams and carpets. Our process identifies the moisture source, eliminates mold and improves ventilation to prevent its return.
Attic and roof space mold
Inadequate ventilation, roof leaks and condensation create conditions conducive to mold in Ottawa attics. Mold attacks insulation, plywood and wood framing. We remove contaminated insulation, treat the structure in depth and ensure proper ventilation to definitively eliminate the problem.
Mold removal challenges specific to Ottawa
Ottawa has a humid continental climate with harsh winters and hot, humid summers. These extreme variations create freeze-thaw cycles that promote water infiltration, excessive condensation and mold growth in basements, crawl spaces and attics.
Many properties in historic neighbourhoods such as the Glebe, Sandy Hill and ByWard Market were built with ventilation systems inadequate by modern standards. This insufficient ventilation creates pockets of stagnant moisture where mold thrives rapidly.
The proximity of the Ottawa River and Rideau Canal exposes several areas to recurring spring flooding risks. These floods often leave moisture traces in foundations and basements, creating fertile ground for mold if not treated quickly by professionals.

Frequently asked questions about mold removal in Ottawa
How do I know if I have mold in my house?
Common signs include black, green or brown stains on walls or ceilings, a persistent musty odour, excessive condensation on windows, respiratory problems among occupants and recent or past water damage. If you suspect mold, a professional inspection is recommended.
Is mold dangerous for my health?
Yes. Mold exposure can cause eye and throat irritation, coughing, wheezing, allergic reactions and aggravate asthma. Some toxic molds like Stachybotrys can cause more serious health problems. Sensitive individuals, children and elderly people are particularly at risk.
Can I remove the mold myself?
For very small surface areas (less than 1 square metre) of superficial mold, personal cleaning may suffice. However, for larger contaminations, mold hidden in walls or after water damage, intervention by certified professionals is strongly recommended to guarantee complete and safe elimination.
How long does mold removal take?
For minor interventions, treatment can be completed in 1 to 2 days. For significant contaminations requiring drywall and material removal, the process can take 3 to 7 days including complete drying and final verification.
Do I need to leave my house during work?
For minor interventions with proper containment, you can remain in unaffected areas. For significant contaminations, particularly with toxic black mold, it is recommended to leave the premises for the duration of work to avoid spore exposure.
How do I prevent mold from returning?
The key is to control humidity. Maintain indoor humidity between 30% and 50%, ensure adequate ventilation, repair water leaks promptly, use dehumidifiers in basements, clean gutters regularly and ensure adequate drainage around foundations.
