Eco Flo Plumbing spent a lot of time preparing an estimate for me. The company also made two visits to my home for thorough inspections of my job site. The price quoted to me was fair and reasonable, and the sales person was extremely personable! I Wholeheartedly Recommend EcoFlow !

Rocco was amazing. I would recommend him for any and every repair or build. He has a charming old-world skillset so everything was built with superior integrity that will outlast the test of time. If I could give him 11 stars, I would. Choose Rocco!

No, not all popcorn ceilings have asbestos, but a vast majority do. The Environmental Protection Agency (EPA) banned its use in 1973, although it still may have been used up through the early ‘90s. But, in general, homes built or remodeled before the early ‘80s likely utilized materials with asbestos. That being said, a professional test is the only way to determine for sure.

Asbestos testing is conducted by collecting samples from materials suspected to contain asbestos and analyzing them in laboratories for confirmed presence.

The microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working.

Because of the danger of inhaling asbestos fibers, figuring out through testing whether your popcorn ceiling contains asbestos is definitely worth it. If the popcorn ceiling texture has asbestos, remove it as soon as possible to keep your family safe. Any home built in or before the 1980s that has popcorn ceilings could have asbestos, necessitating testing. Asbestos carries several health risks for people who inhale it, including the increased chance of developing lung cancer in the future.
