Prevent Recurring Problems – don’t waste time and money dealing with the same problem over and over again. Recur is defined as “to occur again, periodically, or repeatedly.” In our mold and moisture work, we see many instances where mold and moisture problems recur. Why is that? As it turns out, there are many reasons. A lot of these reasons have to do with complicated physics – the Second Law of Thermodynamics for example. There are tons of great websites, magazine articles, and books that explain all this in exhaustive detail – I just gave you the short answer. Practically speaking, the “real” reason is many times much easier to understand. Maybe the building owner thought the problem was fixed and mold and moisture problems wouldn’t happen again. Maybe the previous project solved part of the problem, but there was something else missed, and now it’s causing mold and moisture problems. Maybe there’s not enough money right now. Often though, we notice that mold and moisture problems are cyclical, almost following the calendar. When the weather starts to warm up, we get more and more calls from building owners having mold and moisture problems. “Can you come out and look at this?” – so we go out, look at it, take samples, and tell them they do indeed have a mold or moisture problem. Gee thanks, Chris! “So what do we need to do to clean it up?” – we tell them. Maybe remediation happens, maybe not. One important question is many times not asked: what caused the problem? Another important question is also left out: what has to happen to keep this from coming back? Those two questions are what I want to get at. I want to help my client get to the cause AND the real solution. Is it useful to know what type of mold is present? Sure, but it doesn’t stop there. Likewise, the work probably shouldn’t stop when the mold cleanup is finished. More often than not, our work stops after the mold remediation. Maybe the owner doesn’t want to carry out the time consuming and expensive renovation or HVAC modification necessary to solve the problem. Or maybe repeating remediation is easier than the long term fix. It’s not – we’re just delaying the real fix. But hey, I’ll worry about that next quarter, or next year…. Whatever caused the mold or moisture problem, the remediation phase should also include eliminating the cause – in order to prevent recurrence. In other words, do this once, eliminate recurrence of the mold and moisture problems you’re fighting. One thing’s for sure, if you have a mold and moisture problem, and you don’t eliminate what caused the mold and moisture problem to occur, the remediation work you’re doing now is only a dress rehearsal for the next time the problem occurs. Be ready to remediate all over again. The good news is you won’t have to call me to come back and take samples, because you’ll already know you have mold. I know that’s not exactly a revelation, but it happens – a lot. And I know building owners and occupants are frustrated when they keep fighting (and appearing to solve) the same problem over and over again. So why doesn’t the full solution play out? Sometimes the weather changes and the problem appears to go away. But sometime the problem comes back as soon as the hot, humid times return. And here in Louisiana, that doesn’t take long. Some owners are ok with cleaning up one time, knowing the mold will come back. Whatever the reason, it’s not much fun to work on the project and not achieve the actual goal – remediating a mold or moisture problem AND keeping the problem from returning. It’s not much fun to be asked, “Why didn’t you get this right the first time?”. So why this a seasonal thing? Well, one day, our buildings seem to be wringing wet, mold is growing like crazy, and we have to do something. The next thing you know, it cools down, and the mold goes away, or the wet materials seem to dry out. So the problem’s solved – right? Since that’s the case, we don’t need to do anything else, do we? Well, it depends. If your goal is to get by until you really, really have to clean it up, ok. If your goal is to prevent recurrence, you have to work the problem through to the end. One thing I’ve yet to mention directly is the case where the owner may have received bad advice from a consultant or contractor. I may have done a great job at determining where the mold is, what kind it is, and how to clean it up – but if I didn’t do a good job of finding the cause and recommending a solution, then the problem won’t get solved on its own. The ceiling shown in the picture below could be materal that’s gotten wet over the last twenty years, and now it’s damaged and has mold. That’s not good, but what if that ceiling was only five or six years old, and this was the second or third time the owner’s had to remediate?
