Detect the problem
How to know if there is
Mold in your home?
The presence of mold in a building is never a coincidence. At GEQ,
We translate the symptoms into a rigorous scientific diagnosis in order to target
precisely the source of the problem — not just its effects.
Suspicious stains
Black, green or white halos at the bottom of walls, in corners or near windows.
Smell of potting soil
A persistent musty or damp earth smell in the basement or attic.
Degraded materials
Wrinkling plaster, blistering paint, wood that blackens or crumbles prematurely.
Our method
Three vectors of contamination,
a unique protocol.
Envelope & Foundation
Infiltration, cracks, and faulty drainage maintain high humidity in the slab. We analyze thermal bridges and waterproofing to find the source, not just the stain.
Ventilation & attic
Poor ventilation in the attic leads to condensation and frost. We check the airflow and take samples to measure the spore concentration.
Condensation
Infiltration, cracks, and faulty drainage maintain high humidity in the slab. We analyze thermal bridges and waterproofing to find the source, not just the stain.
