What to know about Mold remediation
Mould remediation is the professional cleanup of mould growing inside a home, together with the repair of whatever let it grow. Mould needs only moisture and something to feed on, such as the paper face of drywall, wood, dust or fabric, and Canadian houses offer both: basements that stay damp through the spring, bathrooms without enough ventilation, windows streaming with condensation in January and slow leaks hidden behind finished walls. Health Canada notes that mould can begin to grow within 48 hours wherever there is excess moisture.

How to choose mould remediation specialists in North York
- Choose a contractor who finds the source of the water before recommending a fix, whether that's grading, eavestroughs, cracks or drainage.
- Ask them to explain the difference between interior and exterior waterproofing for your home, and why they recommend one.
- For foundation cracks that are wide, growing or uneven, ask whether a structural engineer should assess them first.
- For mould, asbestos or radon, hire professionals qualified for that specific work, and don't disturb suspect materials yourself.
- Get a written quote that lists excavation, membranes, weeping tile, sump pumps and restoration of landscaping or finishes.
Questions to ask mould remediation specialists before you hire
- Where do you think the water is coming from, and how did you confirm it?
- Do you recommend interior or exterior waterproofing for my home, and why?
- Should a structural engineer look at these cracks or this wall?
- Does this work need a permit from my municipality?
- Is your warranty transferable if I sell the house, and what does it cover?
- How will you restore the landscaping, driveway or basement finishes afterwards?
- If you find mould or asbestos, how will it be handled and by whom?
Mould removal permits in Ontario
Some mould removal work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
Licensing in Ontario
General contracting and renovation
Renovating an existing home generally doesn’t require an HCRA builder licence: HCRA says renovations or upgrades typically don’t make a home “new”. Ontario advises checking references, WSIB coverage and trade certificates before you hire.
