"Continental Remediation Services provided incredible service when our office flooded and needed immediate attention for moisture control and mold prevention! Dean and his crew showed up within the hour and got right on the problem. They were very knowledgeable and answered any questions we had. Their pricing was great and very fair especially with us being a non-profit! Dean was so honest and definitely a trustworthy resource who cares about his clients! They not only treated the flood right away but also removed all of the damaged carpet and baseboards to ease our worries. I highly recommend Dean and his crew for any emergencies and home related work!"

"After the traumatic and heartbreaking experience of the Palisades fires, we had to go ahead and hire a remediation company. We just finished our remediation with Brett from Hunter Restoration and our apartment smells and looks great! Brett and Braulio did a wonderful job! Not only did they do an amazing job with our unit and were very hardworking and dedicated to making our place look amazing… They were also very compassionate, understanding, patient and worked with us and our situation to be able to make this happen for us as smoothly as possible. I met with almost 8 remediation companies… I’m happy I went with them… I will definitely go back to them for any future jobs I have. I cannot recommend them enough! They did a fantastic job! Thanks Hunter Restoration!"

Mold Testing and Remediation FAQs, answered by experts

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.

Not necessarily. If the mold is only on the surface or in small areas, you may be able to clean it effectively without removing all the caulk. However, if the mold has deeply penetrated the caulk or the caulk is damaged or deteriorating, you should remove the caulk completely and replace it to ensure thorough mold removal and prevent future growth.

If you believe mold is hidden somewhere in your home, don’t delay inspecting it, as it can be dangerous, especially to people with breathing problems and allergies. While it’s possible to learn how to check for mold yourself, we advise most people to hire a professional mold inspector, who can look more thoroughly. You can also purchase mold test kits if you aren’t sure if your home has mold, but a true human inspector is still your best bet.

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.

Most mushrooms found on residential lawns are harmless. Certain varieties such as destroying angel, fly agaric, and vomiter mushrooms that can grow in grass will occasionally make their way onto residential lawn, but this is uncommon. Since mushrooms can be notoriously difficult to identify, if you suspect that your lawn mushrooms could be a poisonous type, consulting a professional is recommended.
