Mold Inspection in Toronto

What We Look For in Toronto Homes

The 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 differ.

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
• Original windows — caulking age, wood frame condition, water staining at sills
• Chimney masonry — mortar condition, flashing, chimney crown

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
• 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
• Kitchen and bathroom supply line age — original supplies on older condos are reaching 25-30 years

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
• Honest "no action needed" report if visual and moisture findings are clean

We will not sell you remediation you do not need. A significant percentage of the Toronto inspections we do result in "clean" reports or in recommendations for simple fixes (ventilation upgrades, dehumidification, minor caulking repairs) that do not require professional remediation. Health Canada guidance is that moisture control is the key to mold prevention — a good inspection tells you what to control, not just what to remediate.
