Believe it or not, there are many different types of molds that can grow in your home. Since they’re all pretty much alike, we’ll just cover the basics and what causes them. Excel Fire And Water Damage Restoration Services offer mold remediation services including removal and cleanup to make sure your home is safe. In this article, we’ll go over the most common causes of mold in homes as well as how to stop their growth before they get out of hand.

Common Causes of Mold in Homes

  1. Constant Humidity: Mold may be an issue if you reside in an area where humidity is constantly high. Because of the high moisture content in the air, this is only normal. This mold will most likely develop on walls, ceilings, dark closets, under the kitchen sink, and other surfaces. Mold produced by humidity is very frequent if you live near the ocean or a major body of water, and it can be aggravated by a lack of ventilation. Moisture buildup in the air indoors may significantly boost mold growth, so make sure to properly ventilate your home, especially during the warmer months.
  2. Home Plumbing Leaks: This is one of the most common causes of mold behind drywall and in under-sink cupboards. As a leak might be coming from the geyser or piping in your roof, leaking pipes can also lead to ceiling and wall mold. If you observe mold growth in any of these places, the obvious next step is to inspect your plumbing for leaks.
  3. Leaking Air-Conditioning System: Most American houses have an air conditioning system, which is also one of the causes of mold. A leaky air conditioning system may aid in the growth of a mold known as Mucor. This is an allergic mold that quickly develops into thick, white patches beneath leaking air conditioning systems or as a result of moisture buildup. Check the pipes, ductwork, and filters of your air conditioner to verify there are no leaks or moisture buildup.
  4. Roof Leaking: A partially damaged roof caused by wear and tear or harsh weather conditions can quickly lead to mold growth in your house. A slow leak may accumulate a large amount of moisture in your ceiling or attic over time. This can eventually lead to mold growing on walls and ceiling planks. To avoid a mold problem in your house, inspect your attic or the tiles and facades of your ceiling for damage and probable leaks.
  5. Poor Home Ventilation: A poorly ventilated home is one of the common causes of mold. Mold thrives in stagnant air, which can be found throughout your home. So make it a point to get rid of it on a daily basis. Humidity is generated in your house by steam from appliances, cooking, and bathing, leaving surfaces wet and sticky. Remove the moisture from your home, and you will eliminate the possibility of mold formation.
  6. Too Much Insulation: One of the causes of mold, believe it or not, is having too much insulation in your home. When this happens, outside air cannot circulate and moisture cannot escape through the walls. Worse, the insulation retains heat along with the moisture, producing the ideal environment for mold development.
  7. Damp Basement: Because they are below ground level, basements are naturally subjected to greater levels of dampness. They are also more likely to have higher humidity levels due to a lack of ventilation or poor air circulation. Water leaks from your house above may potentially accumulate in your basement. This is why, in order to avoid a dangerous mold outbreak, you need to keep your basement in good condition.
  8. Flood: Mold growth is one of the unfortunate truths you’ll confront once your house has been flooded. After a flood, it can take days, if not weeks, for your house to dry out entirely, creating an ideal habitat for mold to thrive.
