What you need to know about Asbestos and Lead

If your building was built before 1980, there’s a good chance you’ve got asbestos, lead, or both hiding somewhere in the structure. And if you’re planning any kind of renovation or demo work, it’s your responsibility to test for and safely remove those materials before construction begins.
Let’s break it down.
Asbestos: The Sneaky One
Asbestos was widely used from 1900 through the 1970s in more than 3,000 products, because it made materials stronger and more fire-resistant. Sounds great, right? Until they realized it causes cancer when it becomes airborne.
Even buildings constructed after 1980 aren’t totally in the clear - some imported products still contained asbestos, so testing is required no matter what year your building went up.
Are you planning a remodel? Your contractor is required to have the affected areas tested for asbestos-containing materials (ACM). Usually, they’ll bring in a subcontractor for this, but it’s worth asking who they’re using and making sure they’re actually certified.

Where asbestos tends to show up:
Adhesives under floor tiles and sheet flooring
Plaster compounds on walls
Roofing shingles and materials
Pipe wrap (especially around boiler and steam lines)
Spray-applied fireproofing
Spoiler alert: it can be anywhere. Testing doesn’t take long, and results usually come back within a few days. But abatement contractors book out fast, so get your testing scheduled early!
Lead: The Classic Offender
Most people associate lead with old paint, but it was also used in:
Plumbing pipes and solder
Bronze faucets and fixtures
Roofing materials
Vinyl flooring
Water lines
Even soil, from years of chipping paint or leaching
Any demolition, excavation, or even light digging in older soil requires testing for lead. If it's found, it needs to be removed or safely encapsulated by an EPA-certified contractor.
