Mould removal and inspection in Scarborough

Scarborough has one of the highest concentrations of basement apartments in the GTA. Many of those suites are in post-war homes that have experienced water intrusion at some point, a sewer backup, a foundation seepage, or a flood that was mopped up and never professionally dried. In those spaces, mould often develops inside wall cavities and behind baseboards without the occupant seeing it until the smell becomes impossible to ignore.

Attic mould is also common in Scarborough's older detached homes. Bathroom exhaust fans that vent directly into the attic space, rather than through the roof, pump moisture into the attic year-round, and with inadequate ventilation, mould colonizes the underside of the sheathing. It can be extensive before anyone thinks to look.

We do full mould inspections to find the source and scope, not just treat what is visible. Our IICRC certified crews contain the affected area with negative air pressure so spores do not spread to other parts of the house during removal. We treat surfaces, remove contaminated material, and coordinate post-remediation clearance testing to confirm the area is safe.

Don't disturb mould without containment

Scrubbing or pulling out drywall without negative air containment spreads spores throughout the house and almost always makes the problem significantly worse. A certified crew with the right equipment is not a luxury, it is how the job gets done properly.

Questions from Scarborough homeowners about mould

How do I know if I have mould after a basement flood in Scarborough?
The most common signs are a persistent musty smell, visible dark discolouration on drywall or framing, and allergy-like symptoms that improve when you leave the house. Mould can also be growing inside walls with no visible sign if moisture was left untreated after a flood. If you had a water event in the last 6 to 12 months and the area wasn't professionally dried, an inspection is worth doing.
We have a basement apartment with mould under the bathroom vanity and along the base of one wall. Is this a big job?
It depends on how far it has spread. Surface mould on a non-porous material can be limited, but mould along the base of a wall usually means it has gotten into the drywall and possibly the framing behind it. We inspect to find the extent before any work starts so you know exactly what you are dealing with.
Can we stay in the house during mould remediation?
For contained jobs in one area of the home, it is often possible to stay in the property. Larger jobs, particularly full basement remediations, usually warrant temporary relocation. We assess this case by case and let you know what is safe before work begins.
Do you do the air quality testing as part of the remediation?
We can coordinate post-remediation clearance air testing to confirm the affected area is clean. Post-clearance testing is independent of the remediation work, having a third-party confirm the results is best practice and what most insurance companies expect.
The city of Toronto has flagged that our area has a history of sewer backup. Does that increase mould risk?
Yes. Sewage backups introduce organic matter that mould feeds on, and homes that have had repeated basement water events, even minor ones, are at higher risk for mould in wall cavities and under flooring. If you have had multiple backup events and the basement was never professionally remediated, an inspection makes sense.
