Mold Inspection in Toronto

What We Look For in Toronto Homes

Every mold inspection adapts to the housing type, because what we are looking for in a 1905 Cabbagetown semi is very different from what we are looking for in a 2019 Liberty Village condo. The framework is the same - find the moisture, find the mold, identify the source - but the specific things we check across Toronto housing stock differ by vintage.

Pre-1950 Toronto House Inspection

On older Toronto houses - Cabbagetown, Riverdale, Leslieville, Parkdale, Roncesvalles, the Junction, the Annex, Trinity-Bellwoods, Little Italy, Yorkville - we focus on:

• Stone and brick foundation condition - rising damp, efflorescence, visible water staining, deteriorated pointing
• Finished basement wall cavities - moisture meter readings on drywall, thermal imaging for hidden wet spots behind paneling
• Plaster walls at bathrooms and kitchens - long-term slow leaks behind original plaster often produce hidden mold invisible until the wall is opened
• Complex rooflines - valleys, parapets, dormers, bay windows; each is a potential failure point
• Attic spaces - ventilation adequacy, bathroom fan termination, roof sheathing staining

Postwar and Mid-Century Toronto House Inspection

East York, North Toronto, Forest Hill, Davisville, and parts of Etobicoke have extensive 1945-1975 housing. Inspection priorities:

• Basement finishing over uninsulated concrete - 1970s-80s rec rooms are frequent mold zones hidden behind panelling, and the most common scope conversion from inspection to mold remediation in Toronto
• Attic ventilation - bathroom fans often vented into the attic, especially in homes where upstairs bathrooms were added after original construction
• Original windows and flashing - aluminum sliders from the 1960s often have failed weather sealing
• Concrete block foundation condition - cracks, efflorescence, wall cavity moisture
• Kitchen and bathroom plumbing - original supply lines and drain assemblies in walls

Toronto Condo Inspection

For condo units - mostly along Yonge, King-Spadina, Queens Quay, City Place, and the dense downtown corridors - we focus on:

• Bathroom exhaust capacity and ducting integrity - often the source of bathroom ceiling mold
• Bedroom exterior walls and corners - thermal bridging behind furniture is the common condo mold zone
• Window and balcony door threshold condition - aging caulking and gasket failure
• HVAC system - fan coil unit condition, condensate drain, return plenum inspection
• Ceiling stains - indicating upstairs unit water events; source identification matters for insurance

Our Inspection Deliverable

Every inspection produces a written report that includes:

• Photo-documented findings, indexed by location
• Moisture map of any wet areas with meter readings
• Thermal imaging documentation of hidden moisture
• Humidity and HVAC findings
• Written scope recommendation if remediation is needed, with cost estimate
