Paid contract work for new and renovated buildings implies a professional responsibility for planners, designers and installers on a job. You must know your obligations, communicating expectations and problems clearly with clients and your fellow workers.

These professional obligations include the following:

• Have a plan for your work, from start to finish, and stick to the plan.
• Identify and be aware of hazardous materials on the job site;
• Install insulation to the standards of the NBC and local codes/by-laws;
• Follow the construction safety laws of the area/location of the job site. Ensure proper training for yourself and your employees;
• Inform clients in writing of any potential issues that could arise from installing insulation or creating a tighter envelope;
• Know the risks you may be creating by altering the building envelope;
• Ensure that all tools, equipment and machinery are in good working order.
  
• If combustion spillage susceptible appliances are present, inform the client of the risks in writing so they can contact the appropriate professionals to mitigate the risk;
• Moisture is the enemy of your work. Ensure that materials and methods are used to prevent the entry of water and moisture into building envelope assemblies.
