"Undaunted removed asbestos siding and contracted to install new siding thereafter. The entire process took a week. The crews were unfailingly professional and attentive, offering to install a light fixture and repair a porch post free of charge. Excellent company."

"I hired Kascon to do asbestos abatement in my attic. I worked with Keith Carroll as my primary contact, he was outstanding. Keith was prompt courteous knowledgeable and extremely helpful. The back office crew was equally oppressive in assisting me with documentation billing etc. as were the gentlemen who showed up to do the abatement work. They were neat and meticulous, showed up when they said they were going to show and did a great job cleaning out not only the asbestos but contaminated wood and materials. Would absolutely recommend this company to anyone who needs asbestos abatement work done. Ask for Keith, you will not be disappointed."

"I called Adam’s Asbestos and Mold testing after we had a small fire and our contractor told us there may be an asbestos issue. Adam himself called me back within minutes, and he was at the house right away! He was professional and very detailed in his work. Best part was, that due to Adam’s report, our renovation was covered by insurance!!! Huge thank you to Adam’s Asbestos & Mold testing!"

"I had a great experience working with Diego and D&C Construction Group. I initially hired them through Angi for siding on my home, and I was immediately impressed by both the quality of their work and how quickly the project was completed. The craftsmanship and attention to detail really stood out, and the team was professional and easy to work with from start to finish. Because of how satisfied I was with the siding project, I didn’t hesitate to hire them again to install a new roof—and they delivered the same outstanding results. Their pricing was very fair, especially considering the level of service and quality they provide. I highly recommend Diego and D&C Construction Group to anyone looking for reliable, efficient, and high-quality work."

"They did an excellent job removing asbestos from pipes in my basement. You can't even tell anything was there. They did an excellent job, were prompt and efficient and cleaned up everything at the end of the day and kept me informed of the steps they were completing as they progressed through the day. The office then called on Monday to ensure I was satisfied with the work the crew performed over the weekend. Great company, I would highly recommend them."

Asbestos Removal FAQs, answered by experts

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. 

Follow recommendations for removal or remediation to ensure a safe living environment.

It is best to wear a respirator during the sanding, painting, and sealing process. It can filter particles, vapors, and fumes that can be toxic to breathe. So it’s better to be safe and protect your lungs during this project.

If the tiles are undamaged and in good condition, painting can be a safe method of encapsulating them, but it is important first to evaluate the state of the tiles before proceeding. If the tiles are deteriorating, damaged, or already loose, simply painting over them fails to address the underlying issues that can cause asbestos exposure. It is recommended to consult asbestos abatement experts in such situations to identify the best way to safely manage or remove the asbestos-containing materials. During the painting process, it is crucial to adhere to safety regulations and guidelines to reduce the potential health risks associated with asbestos exposure.

You are not really supposed to seal asbestos with paint, but in theory it could work—the caveat being that this is extremely dangerous and should be avoided at all costs. The only real way to seal asbestos is with the professional application of an encapsulating material like epoxy. Due to the negative effect asbestos can have on your home, however, it is usually the best course of action to accept a costly fix and remove the material entirely.
