  • Mold Remediation OttawaWhen mold growth is found within an indoor environment, the cleanup costs can become subtantial if the problem is allowed to persist for prolonged periods of time.Learn More


  • We develop and implement site specific sampling plans when we inspect buildings facing difficult IAQ issues. During a standard inspection we can measure the precense of contaminants such as TVOCs, CO2, particulates, and formaldehyde off-gassing.


  • From testing for possible hidden mold growth, to assessing the scope of contamination that may require abatement. Our mold inspections and mold sampling plans are tailored to meet your specific project needs, as well as priced to fit your budget.


  • If you are planning or are in the process of begining a building renovation project, you need to complete an abestos survey in order to meet mandatory Ontario regulations. Some materials that require testing are plaster, pipe insulation, and ceiling/floor tiles.


  • Mold remediation projects should begin with an assessment of the work site in order to determine the extent of the contamination, and to formulate a proper plan with clear goals and expectations that can be verified by an indoor environmental professional.
