The Most Common Causes of Mold in Households

The last thing anyone wants is a house full of mold. Even if you maintain a clean home and use disinfectants, there will always be traces of mold spores indoors – although mold needs the right environment to grow.


Unfortunately, the conditions that cause rapid mold growth can commonly be found in homes. Even if you think there are no signs of mold in your home, there could be tell-tale signs that you are overlooking. 


If you are unsure whether your home has mold, hiring a trusted professional team to conduct a mold inspection and testing can help you know for sure. At Mold Masters, we help Florida homeowners with mold remediation and removal of any overgrowth.  


Let’s look at the common culprits that cause mold in homes to better understand why mold overgrowth occurs.

Constant Humidity

 

With warm weather, the air in houses can become damp and humid. Many scenarios can increase humidity in homes. Whether it is caused by humid weather, continuous rain, cooking in a poorly ventilated kitchen, or showering – it can increase the likelihood of mold growth in your home. 

 

Poor Ventilation

 

When the air within your residence isn’t properly ventilated, this can lead to increased humidity which, as we already covered, increases mold growth inside the home. To prevent this from happening, make sure your home is well ventilated by opening windows and/or doors when it is practical to do so. If opening windows and doors is impossible, you may use fans to control the humidity inside your home.

 

Condensation Buildup

 

When dampness occurs, it is because of condensation buildup inside the home. This dampness can lead to mold growth that will appear in the corners of rooms, behind furniture, inside wardrobes, and in more serious cases, on ceilings. At Mold Masters, we deal with minor and severe mold problems and provide comprehensive mold removal services.

 

Leaky Pipes and HVAC Systems

 

Leaking pipes are a common problem in homes and need to be fixed immediately. Oftentimes, your house may have a leaky pipe that is hidden from your view. 


Leakage can wreak havoc inside your walls, and you may only notice once the problem is severe. Be sure to inspect your walls for water stains often.

 

As warm weather arrives, you will likely be using your HVAC system more frequently – and there may be water leaking from your HVAC unit. Water buildup inside your home is never a good sign and should be attended to immediately to prevent damage to your home.

 

Leaky Roof

 

Roof leaks are another way for moisture and water to seep into your home and cause mold. This could be due to damage to your roof. Check regularly for any water stains on your ceiling. If you notice water damage, have your roof inspected before the problem gets worse.

 

Flooding

 

Flooding can bring copious amounts of water into your home – this will cause severe water damage and possible mold growth within 24-48 hours. It is important to call a professional restoration company, such as Mold Masters, after the incident for possible damage prevention and mold remediation.
