Musty smell but nothing visible? Unexplained allergies indoors? Buying or selling a home? Get facts before you get quotes.
We'll be straight with you: if you can see a large patch of mold and you know where the water came from, you don't need a test — you need remediation. Testing earns its money in the situations where you can't see the problem:
The full property — basement, attic, bathrooms, plumbing, windows and exterior grading. In London's older neighbourhoods we focus on stone foundations, plaster walls and attic ventilation; in newer subdivisions, finished basements and bathroom exhaust routing are the usual suspects.
Pin and pinless meters on suspect walls, floors, and framing — mold needs water, so we follow the moisture.
Where useful, to spot temperature anomalies that indicate hidden dampness behind finished surfaces.
Indoor air samples compared against an outdoor baseline, analyzed by an independent accredited lab. Elevated spore counts indoors tell us there's a source, even when it's hidden.
Tape or swab samples when we need to confirm whether a stain is mold and what species it is.
Photos, readings, lab results — and most importantly, what to do next. If remediation is warranted, you'll know the scope. If it isn't, we'll say so.
The dirty secret of "free mold inspections" is that a company that only makes money on removal has every incentive to find a removal job. Our inspection is a paid, standalone service that stands on its own: if your musty smell turns out to be a dead mouse in a duct or condensation you can fix with a $60 dehumidifier setting, that's what the report will say.
Standard lab turnaround is 3–5 business days; rush processing is available when a closing date is on the line.
The finished basement that flooded "years ago." Dried on the surface, wet in the wall cavity. Mold grows quietly behind vapour barrier and drywall until the smell gives it away.
Attic mold found during a roof quote or home sale. Usually a bathroom fan venting into the attic, or blocked soffit vents. Common across London's 1970s–90s housing stock.
The north-facing bedroom closet. Cold exterior wall + poor airflow = condensation and a fuzzy surprise behind the winter coats.
Crawlspaces under additions and older cottages — bare earth floors breathing humidity into the house all summer.
A visual inspection with moisture readings typically runs $200–$400. Air sampling adds lab fees — usually $100–$150 per sample, with 2–3 samples (including the outdoor control) being typical. You'll get exact pricing before we book.
Standard turnaround is 3–5 business days. Rush service is available for real estate deadlines.
Yes, though we always take an outdoor control sample too — indoor counts only mean something compared against what's naturally in the air outside that day.
No. The report is yours. Homeowners aren't required to report residential mold findings to any Ontario authority — what you do with the results is your decision.
Lab-backed answers and a written plan — before anyone quotes you a dollar figure for removal.
