Michael did an excellent job repairing our chimney after a previous contractor's repair fell apart after just a few years. Michael took his time and did the job correctly. I have no doubt his work will stand the test of time and last a lifetime.

Percolation Tests questions, answered by experts

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.

If you know your popcorn ceiling has asbestos, you should not attempt to clean it. It simply is not possible to learn how to clean asbestos safely without potentially releasing microscopic fibers into the air that could lead to severe illness in the future. Avoid disturbing or cleaning the ceiling until the asbestos removal company can get rid of the popcorn ceiling.

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