ALARA Environmental Health and Safety Ltd. specializes in former marijuana grow-op  investigations, testing and clearance.  Many home buyers unknowingly purchase homes that were used as drug houses in the past and still contain toxic mold or other contaminants. Landlords are often the victim of growers and require environmental testing before the house can be occupied again. We can provide the information necessary for buyers, owners and residents of these buildings. Former Marijuana grow operations and drug houses are common in Metro Vancouver and the Fraser Valley. All services are 100% confidential.
