What Is a Hazardous Materials Survey?
A Hazardous Materials Survey is an inspection of a building to identify materials that may pose health, handling or disposal concerns, particularly when disturbed during renovation, demolition or maintenance.
Depending on the building and agreed scope, the survey may address asbestos-containing materials, lead-containing paint, equipment potentially containing polychlorinated biphenyls (PCBs), mercury-containing components and other materials requiring special management.
The assessment combines a building inspection, review of available information, targeted sampling and laboratory analysis where appropriate. Findings are documented in a report that identifies assessed materials, their locations and recommendations for management or further work.
The scope is tailored to the building and project. A survey for a limited renovation differs from an assessment intended to support demolition of an entire structure.
A Hazardous Materials Survey May Include:
✓ Review of building age and available renovation history
✓ Inspection of accessible areas within the agreed scope
✓ Identification of suspect hazardous building materials
✓ Collection of representative material samples
✓ Laboratory analysis for asbestos or lead, where appropriate
✓ Review of accessible equipment labels and identifying information
✓ Photographs and material-location descriptions
✓ Clear recommendations and assessment limitations
Important: Hazardous materials cannot always be identified by appearance. Concealed materials may require intrusive access or further assessment before they are disturbed.
What Does a Hazardous Materials Survey Include?
Project and Building Review
We review the building’s age, available construction information, previous surveys and proposed work. This helps establish which areas and materials need to be assessed.
Building Inspection
Accessible areas within the agreed scope are inspected for suspect hazardous materials. Material locations, visible condition and relevant characteristics are recorded.
Material Sampling
Representative samples of suspect materials are collected where appropriate. Sampling requirements depend on the material, its distribution and the objectives of the survey.
Laboratory Analysis
Selected samples are submitted to a qualified laboratory for analysis. Results help determine whether sampled materials contain asbestos, lead or other substances included in the testing scope.
Material Inventory
Identified and presumed hazardous materials are documented with location descriptions and photographs where appropriate. Estimated quantities may be included where agreed and reasonably assessable.
Reporting and Recommendations
The completed report explains the inspection scope, sampling methods, laboratory findings and limitations. Recommendations help owners and contractors understand which materials may require management, further assessment or specialized removal.
When Do You Need a Hazardous Materials Survey?
A Hazardous Materials Survey is commonly requested before:
-
Building demolition or partial demolition
-
Commercial tenant improvements
-
Interior renovations and building upgrades
-
Removal of walls, ceilings or flooring
-
Mechanical-system replacement
-
Roofing repairs or replacement
-
Repairs that may disturb suspect building materials
-
Redevelopment of an older property
-
Restoration following fire or water damage, where safe access is available
-
Purchasing a property where hazardous building materials are a concern
-
Developing a hazardous materials inventory for building management
Identifying materials before work begins helps reduce unexpected discoveries, exposure risks, project delays and unplanned removal costs.
Working Toward a Renovation or Demolition Deadline?
Send us the property address, a description of the planned work and your required completion date. If available, include floor plans, photographs and previous hazardous materials reports.
We will provide a clear proposal outlining the inspection scope, anticipated sampling, cost and scheduling availability.
Hazardous Materials a Survey Can Identify
Hazardous materials may be present in finishes, insulation, mechanical equipment and other building components. Their presence is not always obvious during a routine property inspection.
Depending on the agreed scope, a survey may assess:
Asbestos-Containing Materials
Suspect materials may include:
-
Drywall joint compound and textured finishes
-
Vinyl floor tiles, sheet flooring and associated adhesives
-
Pipe, boiler and duct insulation
-
Ceiling tiles and other acoustic products
-
Cement board, siding and pipe products
-
Roofing materials
-
Vermiculite insulation
-
Gaskets and other mechanical components
Laboratory testing is generally needed to determine whether a suspect material contains asbestos.
Lead-Containing Paint and Coatings
Paints and coatings may contain lead. Disturbing them through sanding, scraping, cutting or demolition can create exposure concerns.
Targeted sampling can help inform work planning and material handling.
Potential PCB-Containing Equipment
Some older electrical equipment, including certain fluorescent light ballasts, transformers and capacitors, may contain PCBs.
Accessible labels, equipment age and identifying information can help assess whether further investigation or specialized handling is needed.
Mercury-Containing Components
Fluorescent lamps, certain thermostats, switches and other equipment may contain mercury and require appropriate handling and disposal.
Other Materials Requiring Special Management
Depending on the property, the survey may also document refrigerant-containing equipment, stored chemicals or other items relevant to the planned work.
Not every survey includes every material type. The proposal identifies what will be assessed and any exclusions.
Does Finding Hazardous Materials Mean They Must Be Removed Immediately?
No. The appropriate response depends on the material, its condition, location and whether it will be disturbed.
Some intact materials can remain in place under an appropriate management approach. Materials affected by renovation or demolition may require specialized removal or other controls before work proceeds.
Damaged materials or conditions presenting an exposure concern may require more immediate attention.
Nexus explains the findings so owners can distinguish between materials requiring action for the planned work and those requiring ongoing management or further assessment.

Frequently Asked Questions
Is a Hazardous Materials Survey the Same as Asbestos Testing?
Not necessarily. Asbestos testing focuses on determining whether selected materials contain asbestos.
A Hazardous Materials Survey can have a broader scope, including asbestos, lead-containing paint, potentially PCB-containing equipment, mercury-containing components and other specified materials.
Can You Tell Whether a Material Contains Asbestos by Looking at It?
No. Appearance alone cannot reliably confirm whether a material contains asbestos.
Suspect materials generally require laboratory analysis or must be treated as presumed asbestos-containing materials until appropriately assessed.
Does a Phase I ESA Include a Hazardous Materials Survey?
A Phase I ESA may identify potential hazardous building materials during its site inspection, but it does not normally include the detailed inventory or material sampling provided by a dedicated hazardous materials survey.
If renovation or demolition is planned, a separate assessment may be needed.
Do Newer Buildings Need a Survey?
Building age helps guide the assessment, but it does not establish the composition of every material present.
The need for a survey depends on the building materials, renovation history, available documentation and planned work. Some hazards, such as mercury-containing lamps, can also be present in newer buildings.
Will the Survey Identify Materials Behind Walls or Beneath Flooring?
Only where access is available or intrusive investigation is included in the agreed scope.
Concealed materials may remain unassessed if finishes cannot be opened or removed during the survey. The report identifies these limitations and recommends further assessment where warranted.
Does Sampling Damage Building Materials?
Sampling typically involves removing a small portion of the material being tested. This may leave a visible sample location.
More extensive openings may be needed to investigate concealed materials. Access, occupant coordination and any reinstatement requirements should be discussed before the inspection.
Does a Survey Include Hazardous Material Removal?
No. The survey identifies and documents materials and provides recommendations.
Abatement or removal is a separate scope of work performed by appropriately qualified contractors.
Does the Survey Include Air Testing or Clearance Testing?
Not normally. Material sampling determines the composition of selected building materials; it does not measure airborne exposure or confirm conditions following abatement.
Any air monitoring, post-abatement inspection or clearance requirements should be discussed separately.
Does Finding Asbestos Mean the Building Is Unsafe to Occupy?
The presence of asbestos alone does not establish that occupants are being exposed.
Material condition and the likelihood of disturbance are important considerations. Damaged or disturbed asbestos-containing materials can release fibres and require appropriate assessment and controls.
How Long Does a Hazardous Materials Survey Take?
Completion time depends on building size, access, survey scope, the number of samples and laboratory turnaround.
Provide your renovation or demolition deadline when requesting a quote so scheduling can be confirmed.
How Much Does a Hazardous Materials Survey Cost?
The cost depends on the building’s size, location, complexity, assessed areas, sampling requirements and level of reporting.
