   Walker Design Building’s team offers consultation services to guide clients through the regulatory maze, helping them understand their legal obligations and avoid costly fines or project delays.

3. Asbestos Abatement and Removal Asbestos is one of the most dangerous and commonly encountered hazardous materials in building projects. Asbestos fibers, when disturbed, can become airborne and pose serious health risks such as lung cancer, mesothelioma, and asbestosis. Walker Design Building provides professional asbestos abatement services, including safe removal, encapsulation, and disposal in accordance with the stringent guidelines laid out by Ontario Regulation 278/05. The process typically involves sealing off the affected area, using specialized protective equipment, and employing HEPA vacuum systems to prevent contamination.

4. Lead Paint Management Lead paint, often found in buildings constructed before 1978, is another hazardous material that requires careful handling. Inhalation or ingestion of lead dust or chips can lead to severe health issues, particularly for children and pregnant women. Walker Design Building offers lead paint removal, stabilization, and encapsulation services. These processes are carried out under controlled conditions to minimize exposure to lead particles and ensure the safety of both workers and building occupants.

5. Mold Remediation Mold can be a serious issue in damp or water-damaged buildings, causing respiratory problems, allergic reactions, and other health concerns. Walker Design Building provides comprehensive mold remediation services that include moisture control, contamination assessment, and safe removal of mold-infested materials. By addressing the root causes of mold growth, such as poor ventilation or leaks, the company helps prevent future outbreaks and ensures a healthy living or working environment.

6. PCB and Mercury Containment and Disposal Older electrical equipment, fluorescent lighting, and thermostats may contain harmful substances like PCBs and mercury, both of which are classified as hazardous waste.
