ceiling tileEvery year LCS Laboratory analyses about 20,000 samples of older flooring, drywalls, joint compound, ceiling tiles, pipe insulation, attic insulation and all kind of other materials for asbestos contamination.  This page is a collection of answers to the frequently asked questions that we receive from our clients.

  1. What materials do I check for asbestos? You should check every material that you will cut, break or disturb during the renovation project. Asbestos is relatively safe if you do not touch it, so test only what you are planning to work with. We often find asbestos in vinyl flooring, drywall compound. A more or less complete list of construction materials can be found on this page.
  2. Why is asbestos toxic? When you unknowingly disturb an Asbestos Containing Material (ACM), it releases billions of toxic fibers that damage your lungs.
  3. Which construction materials may contain asbestos?  We prepared an illustrated list of construction materials, that may contain asbestos.
  4. Are there any materials that do not contain materials? We have never seen asbestos in wood, steel, glass, red brick, and porcelain.
  5. Until when the asbestos had been used in construction? By 1985 industry mostly stopped using asbestos in construction.  Vermiculite insulation is an exception. It is found even in newer houses.
  6. How much of the sample does the laboratory need for analysis? We need a few grams only. For most materials, this is the size of a teaspoon. The exception is Vermiculite, which is commonly used as attic insulation, where we need a cup full of vermiculite. Please check this article for more details..
  7. How many samples of the same material should I test? Typically you need to test 3 samples of the same material to prove that it is clean. There are situations where you can test one sample and get an answer. Please check this article for additional explanation and reference on current asbestos law.
  8. What is the cost of asbestos testing in construction materials? Please check the prices for different services in this article.

  15. How do I pack the sample for shipping? You can place the sample into 2 Ziploc bags, or a container. Please send the sample in a box or padded envelope. Do not use a simple paper envelope as it will likely break in transit. For additional information please check here

  21. Will the test results show the percentage (%) of asbestos in my sample? Yes we report the concentration and the type of asbestos found
  22. What is a “safe” asbestos limit? “Safe limit” is not a very accurate term. A better term is a “legal limit”: in Ontario, it is 0.5% (2024).  This page explains the difference between safe and legal asbestos limits.
  23. I have many layers in my sample. What should I test? Generally speaking, you need to test them all. Additional information can be found on this page.
  24. Will my test results be confidential, or is your company required to report the results to any regulatory or government agencies? All results are strictly confidential between the client and LCS laboratory. We do not share the results with authorities. The exception is the court order (which has never happened)
  25. I need to show the lab report to my contractor (…, real estate agent, lawyer, Ministry of Environment, etc….). Will they accept it?  There is no reason why they shouldn’t accept our report, but some agencies are trying to force you to use their “trusted” laboratories. To avoid a conflict please download the 2020 Asbestos report, and discuss it with your counterparts before placing the order.
