"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!"

Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

Mold Testing and Remediation FAQs, answered by experts

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.

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’re wondering which is more toxic, laminate vs.vinyl flooring, you might be surprised to learn that both can include toxic chemicals. Depending on the specific brand and the manufacturing process, both are likely made from synthetic materials that can emit volatile organic compounds, or VOCs, into the air. However, since laminate has a wood core, it is more sustainable and less polluting than vinyl, which is entirely synthetic and almost always emits more VOCs than laminate flooring. If you’re concerned about indoor air quality, choose a low-chemical flooring manufacturer or, better yet, choose flooring that doesn’t off-gas VOCs.

Mold can damage the surface it’s growing on, cause mold-related sickness, and even affect your upper respiratory system.

Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure. This is why we recommend a full, professional removal and cleaning of any asbestos found in your home. If you are unsure whether there is any present, you should call a pro who will inspect your property.
