What Building Materials Are At Risk for Mold Infestation

Published on February 17, 2023

Mold can seem mysterious, scary, and unpredictable. When you need mold removal in Vaughan, the priority is to remove the infestation as soon as possible before the mold severely damages your home’s structure. After over a decade of experience helping families with mold removal and mold testing in Vaughan, the MoldTech team has seen a few patterns repeat many times. Mold habitually attacks the same building materials or rooms, and understanding what parts of your home are at risk can help you monitor for emerging problems. 

Here are the top 4 building materials affected by mold infestations.

Attic Insulation 

Mold grows especially well in environments with poor airflow and little traffic, making the attic a common site for mold growth in Vaughan. Issues with the attic can be tough to spot when there’s only a tiny entrance hatch, no light, and no easy way to get up there. Problems with shifting insulation, age, and blocked or insufficient vents can exacerbate minor issues and worsen mould. When you need attic mold removal, contact the MoldTech team for detection and removal services you can count on in Vaughan and elsewhere in the Greater Toronto Area.


Mold can occur anywhere in a home, provided moisture and decent growing conditions are present. While drywall isn’t ideal for mold growth, its paper covering is. Drywall can also absorb a lot of moisture, and because it’s found almost everywhere in our home, it can become a problem in any room, like the kitchen or basement, or around windows and doors. If there is leaks or water damage around drywall or even popcorn ceilings the susceptibility to infestation skyrockets. When you spot mold, act fast by contacting the mold removal leaders at MoldTech. 


Another material that we often find mold growth on is grout. This slightly porous and rough surface can be challenging to clean. Its presence in high-moisture areas like the kitchen, bathroom, or laundry room means it is often a starting point for indoor mold infestations.

Carpet and Textiles

During mold testing in Vaughan, one of mold’s biggest accomplices is carpets and other textiles, like furniture, drapes, or pillows. Many textiles are made from porous organic materials and can absorb (and often retain) moisture — if you’ve ever let a wet towel sit for a few days, you might be familiar with the smell! Drying textiles thoroughly can help you avoid their role in supporting indoor mold growth. 

Look Out for Signs You Have Mold Infestations

While not every home or mold infestation will look alike, here are a few signs the MoldTech team looks out for: 

  • Moisture collecting on the walls, floor, or ceiling. 
  • Discolouration.
  • A musty odour.
  • Problems with humidity. 
  • Peeling paint or wallpaper. 

How to Get Rid of Mold

If you think you have mold, what’s next? We always recommend professional mold removal in Vaughan when you know or suspect you have a mold problem. This is for several reasons:

  • Mold is nearly impossible to remove DIY-style.
