What Lurks in Your Indoor Air
Our comprehensive testing identifies the full spectrum of indoor air quality threats — so nothing goes undetected.
Poor Ventilation
Stale, recirculated air traps contaminants indoors where they concentrate over time.
Allergens & Pathogens
Dust mites, pet dander, bacteria, and viruses thrive in poorly monitored environments.
Hidden Mould
Mould growing behind walls or under floors releases spores that go undetected without testing.
VOCs & Pollutants
Volatile organic compounds from paint, furniture, and cleaning products silently degrade air quality.
