Older buildings require specialized training and skills for renovation and retrofits. Hire qualified professionals to assess, plan and execute any work being done on older buildings.

Altering a building and its conditions for air tightness, insulation and comfort may see you dealing with some of 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 - use recommended personal protective equipment (PPE) and follow recommended and regulatory practices for each situation.

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