"The whole experience was amazing! When Eric came to look at the house he explained everything to us so we would understand the process and what to expect. He let me know how common this happens and it even happened to him recently which made me feel better. They were super efficient, quick, and caring. They even use green products which is a plus having a pet. I would recommend them to friends family and anyone else who needs their help with the services they provide. Very affordable for us and money well spent! Thank you so much for making the house feel more comfortable and the air so much cleaner!"

"They came quickly to inspect the property. It turned out there is no asbestos so they were not needed. They were prompt and helpful nevertheless. If it had been asbestos, we would have hired them."

"Malcolm, Tony and Darren put my worries at ease. My basement flooded and I had major water damage. They immediately came out to assess the damage and developed a plan for cleanup. These guys work hard. They came out and did a demolition and cleaned out my whole basement. I'm very pleased with the price and the work that was done. VODA is a very friendly crew that love animals and love to help people in need. I would recommend them to anyone. THANK YOU AGAIN GUYS FOR ALL YOUR HARD WORK!!!"

Biohazard Remediation FAQs, answered by experts

Professionals will ensure waste is sorted for recycling, thus reducing landfill impact.

If you prefer not to use a commercial cleaning product on your pink mold issue, or on other types of mold you are seeing in your bathroom, there are some natural mold killer products that you can use. You can try substances that you may already have in your home, like vinegar, tea tree oil, hydrogen peroxide, lemon juice, and baking soda.

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

If your roof was constructed between 1930 and 1970, there’s a possibility that the shingles contain asbestos. If that’s the case, you should hire a professional for repairs and replacement, as they’ll have the necessary equipment to stay safe from such a hazardous and cancer-causing substance. If your home was constructed after this period, it’s unlikely that the shingles in place are toxic. In most cases, asbestos shingles are not recyclable, while standard asphalt shingles are recyclable.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.
