Mold, Asbestos Disclosure not Required in La. Home Sales

“Buyer beware: The Louisiana State Board of Home Inspectors Standards and Practice doesn’t require home inspectors to disclose hazardous materials in homes–including asbestos, mold, and even harmful toxic drywall. The reason the for this? Home inspectors are not accredited inspectors for asbestos, mold, and toxic drywall.”

Lead in NOLA Soil Linked to Violent Behavior

“The City of New Orleans has found high levels of lead in public playgrounds and is working to remediate the soil. Part of the issue is the incredibly high number of old houses in New Orleans that were painted with lead-based paint. When it comes time to sand and repaint, not everyone follows the rules to prevent lead from entering the air and eventually winding up in soil.”

Is the Quest for Energy Savings Killing your Indoor Air Quality?

“A lot of focus is put into making a building super “tight” for energy saving purposes.This means wraps, sealants, foams, insulation, etc. are used to reduce air infiltration. These features are excellent for energy savings, but reducing infiltration ventilation in a building can cause indoor mold growth (a large contributor to poor IAQ) and a buildup of indoor air pollutants.”

“I don’t often read The New York Times, but when I do, I usually find something interesting like an article that details an innovative way to use bales of hay as a building material. The Big Bad Wolf and The Three Little Pigs come to mind, but in all seriousness using straw and plaster is not a bad way to utilize a renewable building material as long as you build the walls correctly to avoid moisture intrusion.”

If you’re like me and not in the path of Hurricane Laura, you’ve spent a good bit of time watching Hurricane Laura news coverage. So far it looks like the surge wasn’t nearly as bad as predicted, but Hurricane Laura caused a tremendous amount of damage to Cameron and Calcasieu parishes and the surrounding areas. It’s also too soon to tell how much damage Hurricane Laura will cause as the storm moves inland and dissipates. What’s certain though, is Hurricane Laura will leave a considerable amount of water damage, resulting in water damage restoration and mold remediation. Hurricane Laura environmental cleanup is going to be a huge undertaking and will cause disturbance of asbestos, lead, PCB, and mercury. Proper removal and disposal of those materials is super important. Typically, storm coverage emphasizes water damage and mold remediation. Water damage restoration and mold remediation after Hurricane Laura will be the most obvious cleanup and restoration tasks. But everyone involved with Hurricane Laura environmental cleanup has to consider the other environmental hazards they could encounter. Hurricane Laura environmental cleanup will take time. Response work, particularly environmental cleanup, must balance speediness and caution. This is particularly important since we’ll want to get out right away and assess damage as soon as Hurricane Laura clears out. I know everyone wants to get in and get everything cleaned up and put back together. When we went through Hurricane Gustav (and other storms over the years), I was the same way. But sometimes hasty cleanup efforts can make more of a mess if we don’t slow down and assess all the potential environmental hazards in the work area. We may also put ourselves, co-workers, friends, and family at risk if we unknowingly create an environmental problem. Your safety is the most important consideration. Whether it’s water in the roadways, downed power lines, unstable structures, or contaminated water, make sure it’s safe to move around before you try to get in and assess the damage and environmental hazards. And when the storm is over, we often see hot temperatures return. Dehydration, heat exhaustion, and heat stroke are common problems people face. You’re stressed out and exhausted, and now you’re working in the heat, trying to put your home or business back together. Take care of yourself, then worry about contents – it’s worth repeating that you can always replace buildings and contents, but not people. You can replace buildings and contents, but not people. I won’t get too far into avoiding mold and mold remediation, other than to stress that you need to get the building clean and dry. Maybe Hurricane Laura is the only cause of the mold. Or maybe there’s an ongoing moisture problem that existed before the storm, and now the recovery work has led to discovery of other moisture problems. Find the cause, get the building dried out, cleaned up, and keep the mold from coming back. One other quick reminder on water damage restoration and mold remediation: there is no such thing as a Mold Free Certificate . There’s no requirement to get your home or building certified as “mold free” to make sure you can sell or rent a home or building. Anyone trying to sell you a mold free certificate is trying to scam you. Period.
