Heritage buildings require specialized training for renovation and retrofits. Hire qualified professionals to assess, plan and execute any work being done on older buildings with heritage status.

Altering a building and its conditions for air tightness, insulation and comfort may see you dealing with the following:

• Toxic materials like asbestos, vermiculite and others.
• Dust, mold and spores from animals that may lead to respiratory and nervous system damage
• Unstable structures that are rotted or deteriorated because of moisture damage

Always treat these situations with care and use recommended personal protective equipment (PPE). Don't take chances with your health!!

SPECIAL NOTE: Altering the airtightness and thermal performance of ANY building must be accompanied by ventilation strategies applied by professional HVAC technicians.
