Independent evidence
Laboratory testing
& lab reports.
A result you can hand to someone else.
Some property questions can only be settled by a laboratory. ASM collects the sample, documents the chain of custody, submits it to an accredited third-party laboratory and returns the laboratory report together with a written explanation of what the result means for the building and what should happen next.

What’s included
A complete scope,
not a surface fix.
Airborne and surface mold sampling
Bulk material analysis for asbestos
Documented chain of custody
Accredited third-party laboratory
Laboratory report plus written interpretation
How the work happens
Four clear stages.
One accountable team.
Sampling is completed during the site visit. Laboratory turnaround depends on the analysis selected and the laboratory schedule, and is confirmed before sampling. Expedited analysis is available for some tests at additional cost.
- 01
Define
We agree what question the laboratory result has to answer before anything is sampled.
- 02
Collect
Samples are taken from the right locations and logged with chain of custody.
- 03
Analyze
An accredited third-party laboratory performs the analysis independently of ASM.
- 04
Explain
You receive the laboratory report with a written interpretation and a next step.
Project scope
What shapes the work?
ASM confirms the scope before sampling because the number of samples, the analysis selected and the turnaround you need matter more than a generic online estimate.

What you receive
Sampled. Analyzed.
Documented in writing.
Samples are submitted to an accredited third-party laboratory under documented chain of custody. You receive the laboratory report together with a written interpretation, so the result can be given to a contractor, a landlord, an insurer or the other side of a transaction.

Questions about laboratory testing & reports
Which laboratory does ASM use?+
Samples go to accredited third-party laboratories rather than being analyzed in-house. The laboratory is selected for the analysis required and is independent of ASM, which keeps the result objective rather than an opinion from the party that took the sample.
Do results come back as a pass or a fail?+
Rarely. Most analyses return quantities, species or fibre content rather than a verdict. Airborne spore results are read against an outdoor sample taken the same day; asbestos results report whether the material contains asbestos and at what content.
Why does chain of custody matter?+
Chain of custody is the documented record of who collected the sample, when, from where and how it reached the laboratory. Without it a result can be challenged by an insurer, a landlord or the other side of a transaction.
Can you interpret a lab report I already have?+
Yes. Bring the laboratory report and, if available, the sampling record showing where and when samples were taken. Sampling context matters as much as the figures, so where it is missing the interpretation will say what the report can and cannot establish.

What Ontario property
owners actually say.
Our in-laws were in need of their services. Given their age and condition ASM came highly recommended. The co-ordinator was very courteous and advisd them of any precautions they needed to take before the treatment. Once Syed was on site, he investigated and advised them further. He was quick, friendly and thorough and delivered as promised. Would definitely recommend to any friend or family.
Ali, the inspector/coordinator, super friendly, well spoken, answered any questions we had. Syed, the technician, did a clean, efficient job removing the mold. We got the best quote and they completed with a report and warranty. Will use again.
Amer and his company did a great job with my mold remediation. They were efficient and provided the best price in town with full certification and before and after pictures of work done
Work was done very professionally and they were able to finish in 2-3 hours, which was amazing, recommended required changes and made my life easier. Highly recommended.
