It’s Raining, It’s Pouring, Is Mold growing while I’m Snoring?

With the potential of Rain coming our way, the potential of mold growing in your home is a Possibility. With heavy rainfall comes a tremendous amount of moisture, leaks and condensation increases, temperatures decrease and the amount of warm, drying daylight decreases.

These are optimal conditions for mold growth, both interior and exterior. As exterior mold spores explode in number some of them are bound to settle in our indoor environments. For more info you might want to check out EPA on Mold growth in the home. www.epa.gov/mold#Why

So what can you do to reduce to likelihood mold will take hold?
We have some tips to help minimize the conditions conducive to mold growth and maximize you and your family’s health.

Mold needs 3 conditions for optimal growth:
* The Right temperature. Some mold species can grow at low (below 50 degrees F) and other species at high (above 90 degrees F), but most common mold species that grow indoors grow ideally at 55-85 degrees F. Unfortunately this is the optimal temperature for human comfort. So it is unlikely you can keep your home at a temperature that is inhabitable for mold growth. So we will not concentrate on that.
* An organic food source. Different species of mold like to eat different things, but they all need something organic to munch on. Many mold species love cellulose, i.e. wood and paper. These are the natural composites and when it rains these species start to eat up all the fallen branches and leaves in the forest, as well as our yards emitting millions of spores that make their way into our homes. Inside our homes molds like to eat wood. This is what “dry rot” is, fungi usually consisting of 2 species, Ascospores and Basidiospores. Other species like to eat paper, such as cardboard boxes, books, and paper backed wallboard, such as sheetrock. Pennicillium/Aspergillus and Stachybotrys (more commonly known as toxic black mold) are often found on wet or moist paper. Cladosporium, the species most often found growing on windowsills and in bathrooms, can eat a variety of Biofilms (household dust consisting of epithelial cells (dead skin cells) insect parts, pet dander, natural fibers such as cotton and linen, etc.). Some mold food sources we cannot easily remove from our home such as framing lumber and wallboard, but others we can, such as cardboard boxes.
* Now This is the big one and the one we will be giving tips on below. Mold needs moisture. There is a common saying in our business: “Mold is the symptom, moisture is the problem”. Mold needs some type of moisture weather its water from a leak, flood or some type of water intrusion or high humidity. Water can come from condensation on windowsills and in bathrooms, or from leaks, either internal or external. Without water mold will not become active unless the humidity is high, usually over 60% RH depending on the species. When the humidity is high enough, mold can become active and grow by absorbing moisture directly from the air.

Here are some tips to reduce both food sources and moisture in your home and potentially reduce the likelihood and amount of mold that may grow inside your home:

We will start with the outside first. When it rains water can easily enter what we call the “Building Envelope”. It is very important to make sure your site drainage system is clear from debris and working properly to move rain water away from your home, foundation, and crawlspace.

Clean the roof of any leave or other debris.
Clear gutters
Make sure downspouts are in good condition; not clogged, in need of repair and properly attached properly to any extensions or the site drainage system.
Make sure all property drains are clear of debris and flowing freely.

Check the “Building Envelope” for possible signs of water intrusion, i.e. leaks.
Keep in mind Window and door frames are spots where water can intrude. Check all door and window frame caulking for cracks and gaps and repair where necessary.
Inspect the sealant around roof penetrations. Repair where necessary.
If your home is a stucco building pay close attention to any areas where the stucco maybe bubbling out or falling off. You may want to run your hand over the wall to make sure you dont have any soft spots.
Check building siding for cracks, peeling paint, holes, etc. Anywhere water may be able to get in.

After a heavy rain walk around the entire house and look for standing water, and clogged drains. Look inside the crawlspace and make sure there is no hidden flooding. Carefully check the inside of the house, take a close look at the ceilings, around windows and doors, and walls for small leaks.

** Because all big leaks start out as small leaks! **

Check under sinks and around tubs and toilets to make sure there are no plumbing leaks adding moisture to the interior of your home.

Assuming there are no leaks and your drainage system is working well, what other sources of moisture can address?

Inside a home the occupants can produce a tremendous amount of moisture. On average each human occupant expires (breathes) and perspires (sweats) about 2 POUNDS of water into the air a day. Pets can also add to this moisture source. During the winter we often close our windows, as it is cold out, and most residential heating systems have no way of bringing in fresh air or ventilating out moist, stale interior air. Thus interior humidity can often increase to levels above 60%, which is ideal for mold growth.

So what can you do to help reduce the potential of Mold Growth due to moisture?

* Monitor interior humidity. Small, portable humidity monitors are available for around $10-15 and can be placed around the home. If RH (relative humidity) is consistently above 60%, action should be taken. Ideally, interior RH should be between 45-55% RH. Below 40% RH mucous membranes start to dry out and can cause occupant discomfort.
* Open windows when practicable to help flush out moisture and other interior contaminants. Even 1 hour a day can make a big difference, although 3-4 hours is recommended.
* Run ventilation fans in bathrooms and kitchens to help exhaust excess humidity from cooking and bathing. Run fans in bathrooms for at least 20 minutes after bathing. Timer switches can be installed on most bathroom exhaust fans and are highly recommended.
* Wipe excess condensation from windowsills. Inspect windowsills often. Do not keep curtains closed as this can trap moist, cool air and promote excessive condensation.

So what can you do to help reduce the potential of Mold Growth due to food sources?

* Do not keep books, papers, or cardboard boxes in moist areas such as attics, garages, basements or crawlspaces. Attic and crawlspaces should not be used as storage areas, but if you must store items in a garage or basement, you may want to consider sealed plastic bins.
* Keep areas mold likes to grow clean and dry. This means cleaning dust (biofilms) from windowsills, baseboards, and doorframes. Vacuum carpet regularly with a HEPA vacuum. The recommendation is to vacuum and sweep one day per week PER OCCUPANT, including pets!
* Check behind drapes and furniture for hidden condensation and biofilms. Allow airflow to reach these areas by opening drapes often and moving furniture a few inches from walls, especially exterior walls that can become colder and promote condensation.
* Also, trust your nose, that musty smell is a sure indication of active mold growth. That musty smell is caused by microbial VOC’s, airborne chemicals that are a metabolic by-product of mold digestion.

If you think you have a hidden source of mold, call a professional Certified Microbial Investigator for a full mold inspection. Excessive interior mold can cause structural damage to your home and its contents, as well as allergic and respiratory reactions in some occupants. Take heed and be diligent, and you can survive the rain storms relatively mold-free.

Mold Cleanup 101: Just Say No to Bleach
The Myth about Bleach is not true... Bleach Does Not Kill Mold

Far to often I hear the dreaded words.... I thought it was Mold so I just used bleach to clean it off.

There is a myth that is circulating by many people giving advice about mold and mold remediation. This myth suggests that if you clean up moldy areas in your home with some bleach that this mold will just go away, but this is NOT TRUE. The truth is that cleaning a moldy area in your home with bleach can actually make your mold problems even worse.

It’s pretty common knowledge that if you’re doing mold cleanup around your home that your weapon of choice might be bleach. As is the way with much common knowledge, this is completely false. While using bleach as an antimicrobial is a nice thought, the truth is that bleach doesn’t actually kill mold. Not only is mold caustic (it is capable of burning living tissue — aka. your skin), but when mixed with the right stuff it can actually be toxic.

When mold is faced with bleach, this living organism believes it is under attack from this corrosive substance, which it is. So, it releases mold spores in an attempt to at least have some of its spores survive. When you wipe up after the bleach spray, you could actually be spreading the mold even further than it spread itself.

Furthermore, bleach is mostly made of water – one of the primary things that mold needs to feed on. Though bleach is a strong solution, it can’t pass through many materials in order to get to the roots of the mold infestation. However, the strong, acidic nature of bleach can actually cause your walls and floors to become damaged and porous, meaning that it is easier for mold spores to find comfortable and cozy nooks and crannies in which to multiply.

Something very important to keep in mind, though, is that when you see a little bit of mold in your home, it’s likely that there is a lot you can’t see. The most important aspect of mold removal is to remove the water source.

PLEASE... PLEASE ... don’t try to remove your mold problems with bleach, because you will likely be making things worse. Instead, if you believe you have a mold issue, Contact a Professional. Don’t try to clean up mold yourself, as you may be setting yourself up for an even worse mold problem than you originally had.
Mold in your home can jeopardize your health, so

step 1: Don’t ignore it.

Step 2: Don’t use bleach.

Step 3: Contact a Professional

Superior Mold Testing shared Category 3 LLC's post. ...

We always say when it comes to water damage the faster you clean it up the better off you are. And to leave it to a professional if you don't have the proper tools or knowledge. This water damage in Wading River NY was caused by a faulty water heater and it caused damage to a few areas in the basement. The homeowner decided to do a cleanup himself and then 3 weeks later he realized that he didn't do a proper job and found mold on the walls and contents in a closet that was left unchecked and remained wet. Thankfully the mold contamination hadn't gotten out of control and it was a manageable cleanup. The customer didn't even realize that he could make a claim for such a thing. This turned out to be a learning experience for the homeowner. If you ever have an issue with water damage in your home call us first and we can walk you through the process and assist you in filing your claim. You can count on Category 3 LLC to have your back.
