Kamloops Real Estate Insider Podcast – Interview with Dean Ganie (Norhaz) Host: Parker Bennett Guest: Dean Ganie – Specialist in hazardous material removal from NORHAZ Key Topics Discussed: 1. Hazardous Materials & Indoor Air Quality Dean started in the hazardous materials removal industry in the 1980s as part of a family business. Dean's expertise focuses on asbestos removal and mitigating risks related to lead, mold, radon, and volatile organic compounds. 2. Understanding Radon Gas What is Radon? A radioactive gas released from soil due to the decay of uranium. How Does it Enter Homes? Radon seeps through cracks in concrete, basement floors, and foundation walls. Health Risks: The second leading cause of lung cancer in North America, behind smoking. Testing for Radon: Long-term (12-month) testing is recommended for accuracy. Short-term tests (like 3-day tests often used in real estate) may not reflect actual exposure levels due to seasonal fluctuations. Mitigation Methods: Sub-slab depressurization (a vacuum system beneath the foundation). Pressurizing buildings in large structures. Sealing the slab alone is ineffective. 3. Asbestos in Homes Common Places Where Asbestos is Found: Drywall finishing compounds. Popcorn ceilings. Vinyl flooring (especially 9x9 tiles). Ductwork tape. Vermiculite insulation (often found in attics). Misconceptions About Risk: Asbestos in good condition is not immediately dangerous. Risk occurs when materials are disturbed, releasing fibers into the air. Some materials, like vinyl tiles, are low risk, while others, like popcorn ceilings, release fibers easily. Vermiculite Insulation: Often contains asbestos due to contamination from mines, particularly in Libby, Montana. Testing is unreliable because contamination varies from bag to bag. WorkSafe BC considers all vermiculite to be contaminated. 4. Lead Paint & Other Hazardous Materials Lead is primarily a concern in older paint layers (pre-1980). Lead in duct tape and other materials can be encapsulated rather than removed. Changes in building regulations (as of 2024) now require all demolition and renovation projects to be tested for hazardous materials. 5. Fiberglass Insulation & VOCs (Volatile Organic Compounds) Fiberglass insulation under a microscope resembles asbestos fibers. Formaldehyde and other VOCs off-gas from new construction materials, leading to poor air quality in new homes. Remediation methods include heating the home to 56°C and ventilating to accelerate off-gassing. 6. Mold & Moisture Control Mold Basics: Mold is a natural fungus that thrives in moisture. Not all molds are dangerous, but some (like Stachybotrys, or "toxic black mold") produce harmful mycotoxins. Misconceptions About Mold: Killing mold makes it worse—bleach and chemical sprays cause mold to release spores (sporulation). Proper remediation involves physically removing mold through thorough cleaning. Preventing Mold Growth: Mold needs moisture to grow—control humidity and air circulation. Bathrooms, attics, and poorly ventilated areas are most at risk. The key to preventing mold is removing the moisture source. 7. Real-Life Case Studies & Stories Restaurant Foreclosure: A restaurant sat vacant for eight years, leading to severe mold contamination. The entire basement was covered in thick mold, resembling a rainforest. The building was condemned because remediation was impossible. Hotel in the North Okanagan: A historic hotel had a mold-infested basement with food supplies. A foot-deep layer of mealworms covered the floor. Structural damage from mold and rodents led to condemnation. Contacting Dean Ganie & Norhas Website: www.norhaz.com Email: dean.ganie@norhaz.com Phone: 250-488-6509
