"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

Ensures comprehensive removal and adherence to safety regulations, protecting health.

Asbestos siding can be dangerous, but it doesn't necessarily pose a health risk if it's in good condition and left undisturbed. The danger comes from inhaling asbestos fibers, which can be released if the siding is damaged, deteriorating, crumbling, or disturbed during remodeling or repairs. Exposure to these airborne fibers can cause serious, life-threatening diseases like asbestosis (lung scarring), mesothelioma (an aggressive cancer), and other lung cancers.

If your asbestos siding is intact, the general recommendation is to leave it alone. However, if it's damaged or you plan to renovate, it's crucial to handle it safely. Due to the significant health risks and the difficulty of containing the fibers, it is not recommended to perform any asbestos work yourself. Instead, you should hire a professional asbestos removal company to inspect, repair, encapsulate, or remove the material. The presence of asbestos can also negatively impact your property's value.

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.

In the 1980s, the use of asbestos in house siding materials underwent a significant decline, ultimately being phased out by the mid-1980s to early 1990s. This change was largely due to a growing awareness of the severe health risks associated with asbestos exposure, particularly its link to lung diseases and cancers. With increased public concern and regulatory agency involvement, building codes and regulations were updated to restrict the use of asbestos in construction materials. 

Since DIY asbestos removal isn’t the best option to save money, there are other steps that you can take to help cut costs when dealing with this project. After speaking with your asbestos removal expert, discuss if encapsulation is an option. If it is, you can save between 15% to 25% on overall project costs over demolition and disposal. In addition, when speaking with your professional, discuss if there are any tax credits available for your removal project. Finally, check with your homeowner’s insurance to see if any removal costs might be covered. However, be aware that this is usually only applicable if the asbestos is due to a covered incident, like a tree falling into your roof.
