Gather ‘round the computer screen, as I recite a tale of yore. Way off in a dark and mysterious land known as “Peoria, Illinois” (my hometown) comes the legend of Moldy Mary, and how her magic spoiled fruit helped save millions of lives. This may sound like the talk of storybooks and tall tales… you aren’t likely to see her name in history books.
When people think of mold inside their house, they typically think of a big black splotch on the wall or ceiling. More times than not, this would be correct. But mold has tens of thousands of species and can have a wide variety of colors and show up in different areas for different reasons. Although
When you discover a large mold problem, your top priority is getting it remediated ASAP. In that haste, you may neglect to write out mold remediation plan. This blog post is intended to shed some light on the importance of having a written mold remediation plan when fixing a mold issue. This article will show how a remediation plan is both beneficial to the owner and the remediation contractor.
After mold has been discovered, the primary concern of the property owner is to have remediation. One potential hazard that is often overlooked is the presence of asbestos in the materials that are being remediated. While the EPA has created the RRP Rule (Renovation, Repair, and Painting) to educate contractors about accidentally disturbing lead paint, there is no such rule in regards to asbestos.
As trained professionals in the mold industry, we often get clients who want to know if they can live in a mold free home. The answer to that question is “It depends on your definition of mold-free.” A home can have no significant mold growth but it will always have a background amount of mold spores.
This might be the most common question we receive. Unfortunately, there are no “one size fits all” type answers to this question. Think to yourself “How much does it cost to go to the dentist”? Well if you are just going in for a routine cleaning your cost could be less than $100, but if you need major work done it could be $1000’s. Much like seeing the dentist, each mold situation is so unique pricing can vary. Our mold assessments can cost up to $1000 (and occasionally higher for special projects), but the average cost for a typical residential project is about $600.
In the world of indoor air quality measurements, the turnaround time (TAT) for getting results can vary drastically. While it is possible to give immediate feedback for some indoor air quality parameters, others can take a few days or even a few weeks depending on the type of sampling. The timing is dependant on the type of sample that is taken and consequently the amount of time the laboratory needs to analyze the sample. In this blog post, I’ll cover the turnaround time for our most common mold work.
The answer is that it all depends. Let me try to explain. Mold needs moisture in order to grow. No moisture; no mold. In an attic space, moisture can occur from a leak in the roof or from condensation due to elevated levels of humidity (typically from improper ducting from a bathroom exhaust fan). Mold
We receive many calls from property owners who are concerned about mold in their attic. Most attics tend to be unfinished with exposed sheathing, wood supports, and insulation. Because of this unwelcoming environment, property owners rarely go into their attics which can leave undetected mold problems for long periods of time. In October of 2017,
The mold industry can seem like the wild west. In most states, including Illinois, there are no requirements for someone to call themselves a mold inspector. You may find someone who advertises themselves as being “certified” and features all kinds of official looking seals and stamps on their website, but how do you know if
A funny thing happened during a recent inspection. The client had purchased a home roughly four years ago. She was concerned when a visiting relative complained of having symptoms of her mold allergy while in the property. The client called a mold company to come in and do air testing. Picture her shock when she
During one of my recent inspections, a client presented me a list of questions after the assessment. I often encounter these questions in the field, so I picked out some of the best questions and I am providing the answers below. Q1. Is everything in a room where mold spores are present assumed
Winter brings a unique situation for environmental consultants. With the colder weather and snow cover on the ground that comes with winter in Chicago, there are usually very low outdoor mold levels. Occasionally we can even see outdoor air samples that have no spores present. If you recall from my last blog post on interpreting
My new book, “Fundamentals of Mold Remediation“, was published this week. Over the past few years, I have been collecting my thoughts from designing and evaluating countless mold remediation projects. I have seen some mold projects done right, and many more projects done wrong. There are a number of guidelines and standards on mold
Several of our clients have experienced water intrusion around sliding glass doors. There is a mixed bag of flashing problems that can cause water intrusion. Flashing materials, weep holes, and weep ropes are used to drain water that gets behind the masonry. In this image, the black material beneath the vertical bricks is the flashing
“This is the time of year for mold around Chicago.” This isn’t a quote from an allergist, but rather Dusty Baker, the manager of the Washington Nationals (and past Cubs manager). He made this statement at a press conference after game 4 of the NLDS baseball playoffs, which was postponed due to rain. This was
I have been living in my home for a number of years now and really don’t have any reason to go up in my attic. I would need to get a ladder out and set it up in the middle of my hallway and access the attic through a small door in the ceiling. But
Very often we receive calls from very concerned people that need help determining if they need an Environmental Relative Moldiness Index (ERMI) test or not. The range of knowledge in the general public for this type of test varies. In this post, I will highlight a few points to keep in mind when deciding on
Are you staring at the results of a mold test and struggling to figure out what it all means? Let me try to help you. The most common method used for mold air testing is uses a spore trap cassette. Because there is always a background amount of airborne mold spores, a key step
The drill goes something like this. A mold expert is called into to your home and you find out the bad news that you have mold in your home. The remediation company is called in and after a few hours or a few days worth of work, they report that you are clear of the
