How To Prevent Mold In The Basement? – Mold Busters

When SPUF works out, it can be one of the better performing products in basement applications. Being sprayed directly onto concrete walls, it ensures an even and total protection. SPUF has a high R value per inch, acts as an air barrier and a vapour barrier. However, it has been known to shrink after application, leaving air gaps and a lack of thermal protection.

Another downside to the original SPUF is that some blowing agents have a high global warming potential . For this reason, we like to explore less harmful alternatives whenever possible – though *January 2018 update: new blowing agents for spray foam virtually eliminate green house gases, read more here.

Probably the most worrisome problem is that there is a great temptation for installation contractors to tinker with the chemical mix a bit, giving it more volume with less material, which is more profitable for the installers. There are not a lot of reported cases of this, but when it goes wrong it goes very wrong. Personally, I wouldn’t let someone spray foam in my house without some pretty good references that I followed up.

All that said, here’s how to proceed if you plan to insulate a basement with SPUF:

There have been a few nightmare cases reported where a SPUF installation went very wrong and apparently made homes uninhabitable. Given the fact that application involves a wet spray that hardens on surfaces, it is very difficult to remove.

What Does Mold On Concrete Look Like

Mold on concrete can look like any number of different things. It depends on what classification of mold is growing on the surface of your concrete. It could be white, black or green.

Mold can be harmless or harmful regardless of color, so you should have a professional from Mold Busters visit your property for an expert inspection.

If you mistake black mold for mildew and try to clean it off, you could spread it to the rest of your home. Certain black molds grow in circular formations and are easy to spot however, this is not always the case.

This mold should be treated in the same way as any mold colony growing inside your home.

Use Alcohol Or Vodka For Fragile Materials

Rubbing alcohol or vodka are also mold killers. Using either ingredient is ideal if youre cleaning mold from fragile materials. Spray the alcohol directly onto the surface or use a clean cloth to apply the alcohol and scrub the surface. Rubbing alcohol kills the mold. However, it does not prevent future growth.

Instructions On Mold Prevention In The Basement

To prevent the recurrence or growth of mold, you can take the following steps:

  • Use a vacuum device to filter and purify the air in your home and basement. The machine filters all the air from the room using a process called air ducts. This process filters out all mold spores that can cause mold growth under the right conditions.
  • Eliminate the moisture problem by removing leaks and cracks in the base. If your sump is out of order, make sure it is set up and working again.
  • In rooms with high humidity, install a dehumidifier and a humidity sensor to monitor the humidity level. Always make sure that the humidity always remains below 60%.
  • Cover the base with materials such as plasterboard and primer. In this way, any rise in surface water levels due to flash floods will not penetrate your base, and therefore your home.
  • Buy a mold inhibitor and mix it with the paint you will use to paint the walls of your home and basement.
  • Make sure the gutters are not clogged, and all water collects away from the house. Also, ask your gardener to keep the space around your basement off the base of your home.

Roof and foundation leaks, high interior humidity, overflowing washing machines and more severe forms of flooding are common sources of moisture and are what causes mold in a house. Drywall backing, wallpaper, carpet backing, household dust and wood products are commonly attacked organic materials.

Thereare 4 Primary Reasons For The Increase In Basement Mold

Stop mold from lurking in your basement
  • After about 20-30 years of age, many building foundations made from concrete begin to see some cracking, which leads to water penetration. As you know, mold likes water. Around this time buildings also begin to settle which means there could be a change in how level the basement floor is.
  • Lack of a sump pump, cheap sump pumps, or poorly maintained sump pumps.
  • In older homes, many basements were never truly designed to be finished but finishing a basement has become a popular renovation item. Older basements are not water-tight and many homeowners and even contractors didnt know or didnt bother to waterproof the basements prior to building them out. In addition, when basements are finished, often times there are issues with framing at the joints. This is because two dissimilar materials come together . Every material expands and contracts at a different rate over time and moisture problems easily develop where these materials meet each other.
  • Lack of proper grading, rain gutters and downspouts.

    Common Causes Of Mold In The Basement

    As mentioned above, the main cause of mold in the basement is excess moisture, which is not a rare situation in a basement. Whether that moisture comes from the outside or from the inside, it is very important to get to the root of the problem in order to deal with it and prevent any further complications .

    So, where does the moisture, or water in a basement come from? Lets dig deeper.

    There are two main sources of water in basements:

  • An outside moisture source rain, groundwater, floods.
  • An inside moisture source a high level of humidity and different activities such as drying clothes.
  • Basements are below grade spaces in your home, which means that they are prone to water seeping in from the foundation walls, and window wells. Since these are the lowest parts of the home, gravity dictates that if water is present, it will flow towards the lowest area to settle.

    Two frequent causes of water in basements are rain and floods. Without proper grading, gutters and downspouts, rain often flows into the basement creating excess moisture for mold to thrive in. Flooding caused by heavy rains or rivers, provides the right environment for mold growth.

    When it comes to sources of moisture inside, we can talk about various causes, from ineffective insulation to excess steam that evaporates and raises the level of humidity . A high level of humidity and condensation creates the perfect conditions for both mold and mildew to spread in your basement.

    Did you know?

    How To Measure Humidity

    A hygrometer is a tool people use to identify the levels of humidity in rooms. There are different models on the market, and most of them are quite affordable and available in stores and online.

    Condensation is a visual sign that the humidity in your basement is high, but a hygrometer is the only way to get precise measurements.

    So Why Are Basements Moldy & Damp

    1) The National Building Code now insists on basement insulation , and it needs to be done before delivery to homeowners, which will be years before the concrete in the basement walls has fully dried.

    2) Decisions on wall assemblies and the materials that will be used are most often made based on initial building costs, not future repair costs, energy performance or protecting the health of occupants by mitigating mold formation. They most certainly are not based on the laws of physics,that is the one thing we know for sure.

    3) The cheapest way to insulate a basement is on the inside, and using finishing materials that are moisture and therefore mold formation sensitive. This is a big problem, given the potential for mold problems building like in 1 and 2 above.

    With wet or humid soil on the exterior, concrete cannot dry to the outside. With the inclusion of a polyethylene vapour barrier on the inside, concrete is prevented from drying inwards as well. That leaves a sealed waterproof cavity containing untold thousands of litres of water along with moisture-sensitive and organic materials that are the perfect breeding ground for fungus and mold. Does this sound like a good idea to you?

  • To avoid wet floors and standing water in your basement, install a high quality sump pump like this one with a battery backup system and a perimeter drainage canal.

Sealing the basement slab against water vapor transmission and possible water seepage is the key to preventing mold and mildew. What you use to seal the concrete will make all the difference.
