Frequently Asked Questions About Mold Removal Costs

How much does it cost to get rid of mold?

In Ottawa, professional mold removal typically costs between $500 and $10,000, with most homeowners paying $1,800-$3,500. Small DIY projects under 10 square feet may cost $50-$200 for supplies, but professional remediation is recommended for areas larger than 10 square feet, toxic black mold, or mold affecting HVAC systems.

Is mold remediation worth the cost?

Absolutely. Mold remediation is worth the cost because untreated mold causes serious health problems (respiratory issues, allergies, asthma), structural damage that worsens over time, decreased property value, and potential liability issues. Professional remediation typically costs less than the long-term damage mold causes. In Ottawa's climate, addressing mold quickly prevents it from spreading during humid summer months.

Can I remove mold myself?

You can remove small areas of mold (less than 10 square feet) yourself if it's non-toxic surface mold. However, professional help is necessary for: areas larger than 10 sq ft, black mold (Stachybotrys), mold in HVAC systems, mold behind walls or in crawl spaces, properties with health-vulnerable occupants, or when the mold source is unknown. DIY mold removal costs $50-$200 for supplies but risks incomplete removal.

Does insurance cover mold removal in Ottawa?

Insurance coverage for mold removal depends on the cause. Most Ottawa home insurance policies cover mold if it results from a covered peril like sudden pipe bursts or storm damage. They typically do NOT cover mold from neglect, gradual leaks, or flooding. Review your policy and document everything. The average insurance claim for mold in Canada is $15,000-$30,000 when covered.

How long does mold remediation take?

Mold remediation timelines in Ottawa vary by project size: small areas (1-2 days), medium projects (3-5 days), and large infestations (1-2 weeks). The process includes inspection, containment, removal, cleaning, and verification testing. Ottawa's climate may extend drying times during humid periods.

How much does black mold removal cost?

Black mold (Stachybotrys chartarum) removal in Ottawa costs 10-25% more than regular mold due to its toxicity. Expect to pay: $1,000-$2,500 for small areas, $2,500-$6,000 for medium areas, and $6,000-$15,000+ for large infestations. Black mold requires specialized containment, protective equipment, and disposal procedures, making professional remediation essential.
