FAQ - Odours
Odour problems?
If odours persist or keep returning, there’s usually an underlying cause; Puritas assesses the space methodically and turns the most likely factors into clear next steps you can act on.
Odour Problems?
If odours are persistant or keep coming back, there’s usually an underlying cause: moisture conditions, ventilation patterns, materials, or a hidden source.
Puritas assesses the space methodically, identifies the most likely factors, and translates findings into clear, practical next steps you can act on.
Moisture
Condensation, basement, high-risk areas.
Stagnant air
Insufficient ventilation, rarely used rooms, attics.
Drains / siphon
Sewer smell, dry trap, odor backflow.
Materials
Closets, carpets, wood, subfloors.
Infiltration
After rain: weak points, foundation, roof.
Post-remediation event
After cleaning / work, an odor that comes back
Common leads
An odour doesn’t always have a visible cause; we help clarify likely factors and guide realistic next steps.

An odour doesn’t always have a visible cause; it may relate to moisture conditions, ventilation patterns, drains, materials, or a hidden source. Our goal is to clarify the situation and guide realistic next steps.
What we investigate
We follow the odour—measuring moisture, checking airflow, reviewing materials and drains, and mapping when it happens—so you get clear, practical next steps and we flag when trade input may be warranted (HVAC, plumber).
Moisture
Readings and risk zones (surfaces, basement, condensation).
Ventilation
Airflow and circulation patterns (rooms, bathrooms, basement).
Drains / traps / sewer odours
Screening for dry traps, localized sources, and signs of backflow.
Materials
Areas that absorb or hold odours (closets, carpets, wood, subfloors).
Patterns
Where/when it’s strongest (heating cycles, timing, weather, room use).
What to expect: Typical visit 60–120 min • Verbal or written report • Prioritized recommendations
