Mould Inspection Toronto
A mould inspection Toronto homeowners can rely on begins with the question of where the water is coming from, because growth only lives where moisture does.
Fully licensed and insured
Monday to Sunday: Open 24 hours

What a mould inspection looks at
Our inspection starts with a walk through the areas you are worried about and the rooms around them. We use moisture and thermal tools to find damp materials that look dry on the surface, then trace the pattern back to a likely source such as a plumbing leak, window seepage, roof entry or a past flood that was never dried completely.
Hidden growth is common behind baseboards, under flooring and above ceilings, so a visual check alone can miss it. Where a home has a health concern or an unexplained odour, we also offer indoor air quality testing so you have data about what is circulating, not guesses. If the inspection leads to removal, the same team carries on with the cleanup and the repairs, and we bill your insurance company directly where there is a claim.
What you receive after the visit
- A plain-language explanation of what we found and where
- Moisture findings that point to the likely cause
- A recommendation on whether removal is needed or monitoring is enough
- A written scope and price if work is recommended
Inspection before purchase or renovation
Buyers of older Toronto houses, and owners planning to open walls for a renovation, often want to know what is behind the finishes before spending money. An early inspection can reveal damp framing or a poorly vented bathroom before it turns into a larger repair.
What to do while you wait for an inspection
Until the visit, keep the area ventilated if you can do so safely, and avoid disturbing visible growth by scrubbing or sanding it. Fix an obvious active leak if you can, for example by shutting off the water to a failing fixture. Take dated photos of what you see, including the wall, the ceiling and any stained items. Move belongings away from the affected wall, and note when you first noticed the smell or staining. These small steps give the assessor a clearer picture and help if an insurance claim later becomes relevant.
Toronto homes often have more than one source at work. A bathroom fan that vents into the ceiling, an old window well and a past flood can all contribute to the same basement odour. That is why we look at the whole pattern and not a single spot.
Mould inspection questions
Does the inspection cost anything?
No charge. If removal turns out to be necessary, you get the scope and price in writing afterwards.
Can you tell the type of mould by looking?
Colour alone does not identify a species or its risk. What matters for the home is where the moisture is and how far the growth has spread.
Do you do air testing?
We offer indoor air quality testing for homes where a concern remains after the visual and moisture inspection.
