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 FAQs, answered by experts

The cost for asbestos testing typically ranges from $400 to $800. The final price depends on several factors, including the number of samples needed, the size and age of the property, and the professional's expertise required for comprehensive testing. Larger or older properties may have higher costs.

Asbestos is commonly found in certain older homes, depending on the time period in which they were built. Asbestos use in home construction began in the 1920s and peaked after World War II before being limited by legislation in the ’70s, so a house constructed in 1880 is unlikely to contain asbestos, while one built in 1950 is much more likely to. Research a home’s history to determine the time period when it was built and any renovations made since.

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.

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.

Bathroom tiles can contain asbestos, just the same as patio tiles or kitchen tiles. Remember that asbestos was used primarily for its insulative and fire-resistant properties, both of which are desired in a house. Before we knew asbestos caused cancers and other diseases, it made a lot of sense to include it in many different building materials, including bathroom tiles.
