What Causes Mold Or Mildew Inside The House

Mildew can show up in rooms with high levels of humidity such as bathrooms, kitchens or basements and can appear as black, gray, green or brown spots. Areas in the home with high levels of humidity that are without proper or adequate fresh air circulation can eventually create mold or mildew problems.

To prevent mildew buildup ensure you create good air circulation within the home by installing bathroom vents that lead to the outdoors, replace air filters on furnaces and/or air conditioners at recommended intervals, open windows even slightly to allow some fresh air to circulate through the room. You should also make sure the proper ventilation is set up for any washers and dryers in any basement or laundry room.

Mold is typically caused by water leaks where the water infiltrates the drywall materials of the ceiling or walls and is left to sit and soak into the drywall for a long period of time.

Leaks are usually caused from leaks from a bathtub, a toilet, a water faucet or sink, a leaking roof or from flood damage. It is imperative to find the source of the water damage causing the mold and fixing it before it wreaks havoc on your home and your health.

Paint itself is not a cause of mold or mildew but the appearance of bubbling paint, peeling or cracking paint are usually signs that high levels of moisture are present and that immediate action should be taken.

My Experience: Combating Mould Under A Fresh Coat Of Paint

1) Diagnose The first thing I did was scrape off a small area of the top coat of paint so I could get a closer look and diagnose the diarrhea stains that were gobbling up the walls. I had to be sure it was mould before treating it with anti-mould remedies.

Fortunately, in my case, it was pretty obvious I was dealing with mould because it looked all moudly and stuff. Good technical diagnosis from me there.

Apparently mould commonly gets confused with dirt . I read that the best way to distinguish between mould and dirt is to apply bleach to the area. If the brown stains lighten then its most likely mould, because bleach wont change the colour of dirt. Im not sure how true that is, but it seemed to be the general consensus among the forum contributors. Either way, I bypassed the bleach test, I just went with my unqualified gut-instinct and my lifetime experience of never dealing with mould. But come on, mould looks like mould! It was definitely mould!

2) Cleaning the surface The aim at this stage was to clean the surface from dirt and rub away as much of the fresh emulsion as possible. I wiped the area down with warm soap water. Surprisingly, the newest layer of paint came off effortlessly. Believe it or not, but mould isnt the most effective adhesive primer. Go figure.

Having rubbed off the majority of the top coat of paint, it soon became clear what I was dealing with. This is what my tenants had painted over:

These areas include bathrooms, kitchens, laundry rooms, humid basements, cabinets under sinks, plumbing areas and storage rooms among other places.

These are the areas that you should always keep an eye on for mold growth. The sooner you catch it, the easier it is to deal with.

One area Ive personally dealt with mold is in the basement of my home when I first moved in. Non-green treated wood was used for the sole plates and drywall came into contact with the concrete floor. This allowed moisture to form on the organic materials in my basement and cause significant mold growth on the framing and drywall. I had to gut and redo my entire basement.

Solve The Water Problem

Mold thrives where there is a damp surface. The first order of business is to solve that dampness. If the mold is a result of a leaky roof or broken pipe, then solving the dampness problem is fairly straightforward: stop the water flow and use blowers to dry out the wet area.

Most people find it more cost-efficient to rent dehumidifiers and blowers for drying out wet wood. However, if you want to buy the equipment, ToolTally has some of the best deals on commercial blowers and humidifiers.

If you are dealing with mold on a porch or exterior wood, it pays to look up. Often this water is coming from above. There may be a gutter that is overflowing and causing the wood to rot from the constant dampness. Or trees might be dropping water on the wood for days following every rain storm.

Another common problem is damp crawlspaces. Damp crawlspaces are a haven for mold and will coat the entire underside of a house with mold growth if given a chance.

If you are dealing with a damp crawlspace, It could be that your house needs some landscaping around the house to route water around the crawlspace. Additionally, the crawlspace vents should be left open to make sure that it airs out properly.

A mildewing bathroom is also common. Older bathrooms tend to lack proper ventilation. Adding a vent even a passive vent can do a lot to help remove mildew problems in a bathroom. If you have a vent, make sure to turn it on while you shower.
