Biohazard Remediation FAQs, answered by experts

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Before you start removing mold, turn off the furnace. Clean away any visible mold from accessible areas using a mixture of water and mild detergent. Change air filters and check for moisture sources like leaks. If the problem persists or it's widespread, hire a local HVAC company for professional cleaning.

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.

Leaving pee on a mattress for an extended period of time will make it harder to remove the moisture, increase the likelihood of unappealing stains forming, and make the urine odor linger for a longer time. Ideally, you should start cleaning a urine-soaked mattress immediately. You can start by spraying a 1:1 solution of white distilled vinegar and water over the stain and then blotting it out. Then, sprinkle baking soda over the affected area, let it sit for 8 to 10 hours, and then vacuum it out. If the issue persists, you might need to dispose of your mattress and replace it.

The answer depends on the size of your home, the type of mold, and your ventilation systems. However, the best answer would be no, you shouldn’t stay in your home. Arrange to be away from your home during the mold remediation process, as mold is often most dangerous when it’s being removed due to the particles being released into the air. Some contractors won’t proceed with the remediation if you or other household members are in the home.
