What should I test for?
Tap "What should I test for?".
What materials of that age may contain — and what to test before you disturb them.
What result should I expect?
A list of things to test for before disturbing — for example aluminum branch wiring, asbestos in older materials, lead paint — each with where it usually sits. It lists what to test; it does not say what is actually there — only a test can.
How do I save, share or get help?
Use the list to book testing before demolition. For suspected asbestos, removal is done under Ontario's asbestos regulation by trained workers.
