While I was painting behind my stove I bent down next to the gas line and actually felt air blowing from a hole in the line onto my cheek--but the air was natural gas. I knew I had smelled some gas, but I kept assuming it was the pilot light. Nope, it was a huge leak in the gas line. No wonder I...

Not happy at all. This company does not have the interest of property owners in mind. The test samples they take are often needless. For example air testing in every room. There are not even quantitative standards from the CDC on what is acceptable air spore counts. Do your research.

Percolation Tests questions, answered by experts

If you have an older electrical system with fraying wires and other signs of damage, removal may be the best course of action. When asbestos begins to break down, it's more likely to become airborne, increasing the risk of health issues when it's inhaled.

However, if the system is in good condition and doesn't have visible signs of wear or damage, leaving it alone may be the safest course of action. An asbestos abatement and removal professional can help you determine the best way to proceed.

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.

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

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.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.
