"If you binge watch home improvement shows on TV like I do, the word, "asbestos" can send you and your budget into a cold sweat! William and his team at Laroue Environmental, LLC did a great job thoroughly explaining the asbestos testing process to me as well as my options should the results come back positive. As a first time home owner myself, the process of renovating can be a bit stressful. Working with Laroue Environmental, LLC was anything BUT stressful. If you do sign up for their testing services, you're in good hands! Good luck on your next home renovation project and stay safe out there!"

"Hamilton's price was competitive. The phone representative sound professional and courteous. However, the technician they sent seem very inexperience. He was performing the work (collecting asbestos samples) via Facetime with another senior technician. Also, he only brought a 2-step ladder trying to climb and pull himself up into the attic; he requested to come back the next day, which I'm not available. I ended up borrowing a 3-step ladder from the occupant for the technician. It was risky seeing him pulling himself up into the attic. On his way down, I have to spot him landing his foot on the ladder since the borrowed ladder was still not tall enough."

"Top Notch was quick to come out and do asbestos testing for me when I needed it for plumbing work. They were communicative and showed up on time. I paid for the lab to do quicker turnaround and had my results the next day."

Asbestos Removal FAQs, answered by experts

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.

Homeowners’ insurance doesn’t often cover the cost to remove asbestos siding, which averages about $2,900. Insurance policies treat the removal of asbestos siding as regular home maintenance, which insurance doesn’t cover. If your siding suffers damage in a storm, though, it’s possible the insurer may cover the replacement cost, even if the damaged siding contains asbestos.

The legality of covering asbestos tile with new flooring can vary by location. In some cities, it is not legal to cover asbestos tile due to the risk of causing fibers to become airborne. While a professional method called encapsulation can seal the asbestos in place, it is not always an appropriate solution. In other areas, covering the tile is a legal and reasonable option to prevent fibers from spreading and reduce health hazards. However, the best long-term solution is to have the asbestos professionally and completely removed from your home.

It is possible to repair an asbestos roof if the damage is minor. However, it is crucial to follow proper safety procedures and regulations while doing so. It’s always recommended to hire a professional asbestos roofing contractor who specializes in asbestos roof repairs to ensure the work is done safely and correctly.

Since the EPA partially banned asbestos in 1989, it is no longer used to manufacture new siding in the United States; production had largely ceased by the early 1980s. Many other countries, such as Canada, Iceland, and Denmark, also have bans on asbestos. However, asbestos siding is still present in many homes built before the late 1980s. The only definitive way to know if your siding contains asbestos is to have it professionally lab-tested.
