Why Mould Grows in Mississauga Homes
Wet basements after storms
Finished basements that took in water in 2024 can hold moisture in drywall, trim, underlay and stored boxes. Mould can begin within 24 to 48 hours of a wetting, so materials that were not dried promptly are worth checking.
Hidden leaks and condensation
A slow pipe leak, a failed seal or steady condensation can keep a wall cavity damp for weeks. Mould there shows first as a musty odour or staining, and a moisture survey finds the source.
Mould in workplaces
Ontario's workplace mould alert puts duties on constructors, employers and supervisors under the Occupational Health and Safety Act. Commercial clients should expect containment, documentation and a clear scope before work begins.
How We Handle Mould Remediation in Mississauga
- You call (289) 274-5747. We ask about the area, the odour, and any recent water, and we schedule an assessment.
- We inspect with moisture meters and thermal imaging to find the extent of the growth and the water source.
- We set up containment with plastic barriers and negative air pressure so spores do not spread to clean areas.
- We remove affected porous materials, HEPA vacuum and clean surfaces, and apply antimicrobial treatment.
- We dry the area to verified targets and confirm the moisture source is corrected before rebuilding.

Signs You Need Mould Remediation, and What To Do First
- A musty or earthy odour in a basement, closet, or crawl space
- Dark spots or fuzzy growth on drywall, wood, or ceiling tiles
- Peeling paint or bubbling wallpaper on exterior or basement walls
- Condensation on windows, pipes, or foundation walls
- Stored boxes or furniture in the basement that feel damp
- Allergy-like symptoms that improve when you leave the house
Do not scrub, spray, or disturb visible mould, because that releases spores into the air. Keep the door to the area closed, run a dehumidifier if you have one, and stop any active leak. Then call (289) 274-5747 for an assessment.
What Affects the Scope and Timeline
The scope depends on how large the affected area is, which materials are involved, and whether the moisture source is still active. Mould on a hard surface can often be cleaned, while mould in drywall, insulation, and carpet pad usually means removal. We map the affected area and write a scope that lists every material we will clean or remove.
A small, contained area can take one to two days. A finished basement or a large area behind walls takes longer because of containment, removal, drying, and rebuilding. We do not close walls until the moisture readings confirm the area is dry.
What We Restore After Mould Growth
- Finished basements
- Drywall and insulation
- Crawl spaces and sill plates
- Attics and roof sheathing
- Bathrooms and kitchens
- Subfloors and framing
- HVAC components
