How to Choose a Mould Removal Company in Kitchener
How to choose a mould removal company in Kitchener — the questions that separate a company that fixes the cause from one that paints over the spots.
There's no licence for mould remediation in Ontario. Anyone with a van and a sprayer can call themselves a mould company, and Kitchener has plenty. The difference between a good one and a bad one shows up about six months after the cheque clears. Here's how to tell them apart beforehand.
Questions worth asking
- What's causing the mould? If they can't tell you — the attic fan, the clay soil and the grade, the cracked block, the shower pan — they haven't looked. A company that starts with "we'll spray it" is a company you'll call again next year.
- How will you contain the area? Poly barriers, negative air, HEPA scrubbers. "We'll keep the door closed" is not containment.
- What comes out and what stays? Mouldy drywall, insulation and carpet come out. Framing gets cleaned. A written scope should say which.
- Do you fix the moisture source or coordinate it? Either is fine. Ignoring it is not.
- How do you verify the job is done? Moisture readings, visual inspection, and third-party air sampling when it's warranted.
- Are you insured, and can I see it? Liability and WSIB.
- Have you done a house like mine? A post-war bungalow attic in Forest Hill is a different job from a finished basement in Stanley Park or a rubble foundation in Cedar Hill.
Red flags
- A quote over the phone with no inspection
- "Fogging" or "ozone treatment" as the whole plan
- Encapsulation (painting over) without removing the material
- Scare tactics about "toxic black mould" to rush a decision
- No written scope, no photos, no moisture readings
Frequently asked questions
Should the inspection company and the remediation company be different?
It's a fair concern. Ask for the inspection report in a form any company can quote from — if it's written that way, the conflict is manageable and you can compare quotes on the same scope.
How much does mould remediation cost in Kitchener?
A small contained area is a few hundred to a couple of thousand dollars; a finished basement or a full attic is considerably more, mostly because of the moisture fix and rebuild. A written scope is the only way to get a real number.
