Not good they had to come back three times to fix issues, the workers were very nice but you could tell they were not trained very well. In the end I had to buy foam board and a foam gun and I spent a couple days tearing out some of what they did and redo it. The reason I knew it wasn’t done...

Percolation Tests questions, answered by experts

Since DIY asbestos removal isn’t the best option to save money, there are other steps that you can take to help cut costs when dealing with this project. After speaking with your asbestos removal expert, discuss if encapsulation is an option. If it is, you can save between 15% to 25% on overall project costs over demolition and disposal. In addition, when speaking with your professional, discuss if there are any tax credits available for your removal project. Finally, check with your homeowner’s insurance to see if any removal costs might be covered. However, be aware that this is usually only applicable if the asbestos is due to a covered incident, like a tree falling into your roof.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Older textures may contain asbestos, requiring careful handling and professional inspection before work begins to ensure safety compliance.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.
