Why Mould Grows in Edmonton Homes
Wet finished basements
Carpet, underlay, drywall and insulation hold water long after the surface feels dry. When a basement floods from melt, a storm or a backup, mould can establish behind walls and under flooring within 24 to 48 hours unless drying reaches those layers.
Hidden leaks after winter
A pipe that split in deep cold may leak quietly behind a wall once the thaw comes. The dampness feeds mould in the cavity, and the first sign is often a musty smell or staining on drywall.
Disturbing mould spreads it
Scrubbing or tearing out mouldy drywall without containment sends spores through the house. Alberta Occupational Health and Safety publishes guidance on mould in the workplace, and we follow the same principles at home: contain, filter the air and remove material carefully.
How We Handle Mould Remediation in Edmonton
- You call (587) 315-1498. 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 (587) 315-1498 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.
