Mold Inspection in London, Ontario

A mold inspection answers one question honestly: what is actually here, and where is it coming from? We walk the home, take moisture readings, sample where the evidence points, send it to an accredited lab, and hand you a plain report. We do not remove anything, so nothing in that report is written to sell you a removal job.

If you have a musty smell you can't place, a dark patch that won't come clean, a basement that flooded, or a disagreement that needs settling, an inspection is the calm first step that replaces guessing with a document.

What an inspection actually covers

An inspection is not someone glancing at a wall and quoting a price. It is a methodical look for moisture, because mold is a moisture problem before it is a mold problem.

• A full visual walk-through of the areas of concern and the usual London trouble spots: basements, bathrooms, around windows, behind and under sinks, the attic hatch, and anywhere there has been a past leak.
• Moisture and humidity readings with a meter, because damp drywall reads long before mold is visible, and a high-humidity basement tells you where the next problem is coming from.
• A sampling plan matched to what we find: air samples to measure what is in the air you breathe, surface samples (tape lift or swab) to identify a visible patch, and a comparison outdoor air sample so the indoor numbers mean something.
• Photographs and notes tied to each sample, so the report is a record you can hand to anyone.

Air sampling versus surface sampling, plainly

People ask which one they need. The honest answer is that they measure different things, and a good inspection uses whichever the situation calls for.

Air sampling captures the spores floating in the air and counts them against an outdoor baseline. It is how you answer "is the air in this room a problem?" and it catches mold you cannot see, including growth behind walls that is releasing spores into the room.

Surface sampling (a tape lift or swab of a visible patch) identifies what a specific stain actually is. It answers "is this dark spot on the bathroom wall mold, and if so, what kind?"

A visible patch usually gets a surface sample to name it, plus an air sample to find out whether it is affecting the air. One without the other tells half the story.

What you get back

The deliverable is the point, so here is exactly what it is: a plain-language report, usually within a few business days of the visit, that states for each sample what was found, whether the level reads normal or elevated against the baseline, the likely moisture source, and the honest next step. If everything reads normal, the report says so in plain words, and you are done. If something is elevated, it points to the one real problem and where it is coming from, so any money you spend goes to the right place instead of everywhere.

Why independent inspection is the whole point

The mold industry has a built-in conflict: the company that inspects for free is usually the company that gets paid to remove. That is not a reason to distrust every remover, but it is a reason to get the diagnosis from someone who does not profit from the cure.

That independence is not a marketing line, it is the business model. It is the same reason a home inspector should not also be the renovation contractor, and the same reason a good asbestos tester sells testing only.

London homes and where they grow mold

London's housing stock and weather point mold to a few predictable places, and knowing them makes an inspection faster and more thorough.

• Basements, especially in the older neighbourhoods (Old North, Old South, Woodfield) where fieldstone and block foundations, past flooding, and low ventilation combine.
• Student rentals around Western and Fanshawe, where a lot of people, a lot of showers, and deferred maintenance meet.
• Attics, where roof-vent and bathroom-fan issues plus London's freeze-thaw create condensation that feeds growth on the sheathing.
• Bathrooms and around windows, the everyday condensation spots in any home.
