  • What is a Designated Substance Survey?
What is a Designated Substance Survey?

A Designated Substance Survey (DSS) is a detailed inspection that identifies regulated hazardous materials—such as asbestos, lead, silica, and others—within a building. It is required before many renovations, demolitions, or major maintenance projects in commercial and some residential properties.

  • Why do I need a DSS for my building?
Why do I need a DSS for my building?

A DSS protects workers and occupants by revealing where designated substances are present, how much there is, and how it may be disturbed. It is often required by law before construction, renovation, or demolition and helps you plan safe, compliant work.

  • Is a DSS required for residential properties?
Is a DSS required for residential properties?

Residential properties are usually not legally required to have a DSS unless they are part of a larger complex or being converted for commercial use. However, homeowners planning renovations in older homes often choose a DSS to proactively identify hidden hazards.

  • Who performs a Designated Substance Survey?
Who performs a Designated Substance Survey?

A DSS must be completed by a qualified and licensed consultant trained in hazardous materials identification. At Envirocomm, our certified professionals follow strict protocols and documentation standards to ensure accuracy and compliance.

  • How long does a Designated Substance Survey take?
How long does a Designated Substance Survey take?

The time depends on the size and complexity of the building. A typical small home may take a few hours, while a large commercial building can take one or more days. We provide a clear schedule and scope before starting the survey.

  • When is a DSS required for a construction project or property repair?
When is a DSS required for a construction project or property repair?

A DSS is a regulatory requirement that applies to construction projects and repair operations in buildings where designated substances are or may be present. This is covered under specific regulations like O.Reg-278-05 and 490/09 O.Reg.

  • What is asbestos testing and why is it important?
What is asbestos testing and why is it important?

Asbestos testing involves collecting samples from suspect materials and having them analyzed in an accredited lab to confirm the presence of asbestos fibers. Testing is essential before any renovation, demolition, or disturbance of materials in older homes or buildings.

  • Should I get asbestos testing done in my home?
Should I get asbestos testing done in my home?

If your home was built before the mid‑1980s (and even some newer homes), materials such as insulation, floor tiles, and siding may contain asbestos. Testing is recommended if you plan to renovate, replace flooring, or disturb walls or ceilings.

  • Do commercial buildings need regular asbestos testing?
Do commercial buildings need regular asbestos testing?

Commercial buildings are not required to test routinely if asbestos is already known and managed, but new construction, renovations, or occupant concerns often trigger targeted asbestos testing. Periodic reassessment helps ensure ongoing safety and compliance.

  • How is asbestos testing performed?
How is asbestos testing performed?

A trained inspector carefully collects small samples from suspect materials using safe containment and PPE. Samples are sent to an accredited laboratory, and results are reported with clear guidance on health risks and next steps.

  • How long does it take to get asbestos test results?
How long does it take to get asbestos test results?

Most accredited labs provide asbestos test results within 24–72 hours after receiving samples. We ensure quick turnaround so you can make timely decisions about repairs, renovations, or abatement.

  • Can the property inspector test for asbestos during a visual inspection?
Can the property inspector test for asbestos during a visual inspection?

No, our standard visual property inspection is not an environmental assessment, nor does it include testing for asbestos. If you are concerned about asbestos, we strongly recommend you contact an environmental testing company for a review by a licensed testing lab to ensure safety prior to closing or repairs.

  • What is asbestos abatement?
What is asbestos abatement?

Asbestos abatement means safely removing, encapsulating, or enclosing asbestos‑containing materials to prevent fibers from becoming airborne. It is performed by licensed professionals using strict procedures and protective equipment.

  • When is asbestos abatement necessary?
When is asbestos abatement necessary?

Abatement is needed when asbestos materials are damaged, likely to be disturbed by renovation or demolition, or no longer in good condition. It is also required if the building is changing use or if occupants are at increased risk.

  • Do I need abatement in my home?
Do I need abatement in my home?

If asbestos‑containing materials in your home are intact and undisturbed, they may not need removal. However, if you plan major renovations, repairs, or if the material is crumbling or damaged, abatement by licensed professionals is recommended.

  • How is asbestos abatement done in commercial buildings?
How is asbestos abatement done in commercial buildings?

Commercial abatement involves sealing the work area with containment barriers, using negative air machines and HEPA filters, wearing full PPE, and carefully removing or encapsulating the material. Waste is transported and disposed of at licensed facilities.

  • Is asbestos abatement regulated?
Is asbestos abatement regulated?

Yes. Asbestos abatement is strictly regulated at the federal, provincial, and local levels. Our team follows all applicable laws and safety standards, including proper notifications, work practices, and documentation, to ensure full compliance.

  • What is vermiculite and why is it a concern?
What is vermiculite and why is it a concern?

Vermiculite is a lightweight insulation material often used in attics and walls of older homes. Some vermiculite insulation, especially from the Libby, Montana mine, contains asbestos and can release dangerous fibers if disturbed.

  • Should I have my attic’s vermiculite tested?
Should I have my attic’s vermiculite tested?

If your home was insulated before the 1990s and you have loose, pebble‑like material in the attic, professional testing is strongly recommended before any work, storage, or renovation in that space.

  • Do commercial buildings ever have vermiculite insulation?
Do commercial buildings ever have vermiculite insulation?

Some older commercial and industrial buildings also used vermiculite insulation. If you suspect it in ceilings, walls, or crawl spaces, testing and professional management are important to protect workers and occupants.

  • How is vermiculite safely removed?
How is vermiculite safely removed?

Vermiculite removal is treated like asbestos abatement: the area is sealed off, negative air machines and HEPA filters are used, workers wear full PPE, and the material is carefully bagged and hauled to a licensed disposal site.
