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 it's 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 could lead to respiratory and nervous system damage
• Unstable structure, 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.
