Health
 Mould, mildew- often harmful to respiratory and other health problems
Poor air quality- airflow from indoor parking garages, suite to suite transfer of cigarette smoke.

Safety
 smoke transfer
Decay of exterior finishes - often caused by exfiltration of contaminated air
Prevention of ice dams

Durability
Structural integrity - roofs, walls, windows - all benefit from a better building envelope.

Comfort
Thermal - Warm in winter, cool in summer
Bad smells - eliminating cooking, cigarette smoke from adjoining property
Dirt and pest - a better envelope will keep them out

Energy Efficiency
High energy bills - envelope improvements improve efficiency, lower energy costs and
provide a return on investment
How We Solve Them

Every building envelope improvement we recommend and install is based on sound principles of building science. Understanding how air and air vapour flow in and out of a building - infiltration and exfiltration - is the heart of our problem solving approach.
 
Techniques we use typically include
Air Leakage Testing
Depressurization devices - sometimes known as "blower doors" - combined with smoke generators help us locate and measure air leakage in both large and small buildings.

Air Barrier Continuity
If air barrier defects are identified as the cause of the problem
we use a variety of materials and techniques to restore continuity and strength to the air barrier throughout the building - commonly known as a crack, gap, leak and hole repair.

Insulation
Comfort and energy efficiency demand the correct level of insulation.Part of our building envelope repair process is to assess existing levels and upgrade or replace where needed.
