Question 1

When should I get an air quality test in Guelph?

Accepted Answer

Air quality testing in Guelph is recommended in several situations: after any renovation involving new flooring, cabinetry, paint, or adhesives (peak VOC off-gassing occurs in the first 6–12 months); when occupants experience unexplained persistent headaches, fatigue, respiratory irritation, or worsening allergies; when moving into a newly constructed or recently renovated Guelph home; when an older home has aging HVAC or an HRV that has not been serviced; before or after mold remediation; for landlord-tenant disputes involving indoor air quality complaints; or as a baseline health assessment for families with young children or respiratory conditions.

Question 2

What are VOCs?

Accepted Answer

Volatile organic compounds (VOCs) are carbon-based gases emitted at room temperature from a wide range of building materials and household products: paints, varnishes, and lacquers; flooring adhesives and laminate products; new engineered wood furniture and cabinetry; cleaning products; air fresheners; and carpets. In newly constructed or recently renovated Guelph homes, total VOC concentrations can be 10 times higher than outdoor air. Formaldehyde — a specific VOC of particular health concern — is emitted by pressed wood products, insulation, and certain textiles. Chronic exposure to elevated VOCs causes respiratory irritation, headaches, dizziness, and has been linked to longer-term health effects in sensitive populations. Our AIHA-accredited laboratory identifies individual VOC compounds and compares them against Health Canada and ASHRAE guidelines.

Question 3

Does air quality testing detect mold?

Accepted Answer

Yes — our air quality panel includes airborne mold spore concentration as a measured parameter. The result gives you a total spore count compared against an outdoor control sample, which identifies whether indoor spore levels are elevated relative to the ambient outdoor baseline. However, general air quality testing does not provide species-level identification of mold types. If your results show elevated spore counts, or if you have specific concerns about toxic species like Stachybotrys or Aspergillus, our dedicated mold inspection service uses AIHA-accredited spore trap or PCR/DNA analysis for definitive species identification — the appropriate next step for remediation planning or health assessments in Guelph.

Question 4

How much does air quality testing cost in Guelph?

Accepted Answer

Residential air quality testing in Guelph starts from $299 for a standard panel covering VOCs, formaldehyde, particulate matter, CO2, carbon monoxide, mold spore concentration, and humidity mapping. Comprehensive multi-room testing packages for larger Guelph homes or specific renovation-related concerns run $399–$549. Commercial and multi-unit building air quality assessments are quoted individually based on building size and scope. Results are delivered with AIHA-accredited lab analysis and a written report benchmarking each result against Health Canada, ASHRAE, and WHO indoor air quality guidelines.
