Mold is a type of fungus that grows in the form of multicellular filaments called hyphae. It reproduces by releasing tiny spores that are carried aloft by air conditions. Eventually, the spores settle on an indoor or outdoor surface. If conditions are right, they begin to grow.


When mold begins to grow indoors, it can result in all kinds of issues. As mold proliferates, it deteriorates the surfaces it grows on. This can cause various types of physical damage to a home:

  • Mold is a significant cause of wood rot. Wood rot weakens the structural integrity of wooden beams, joists, and other components, leading to serious structural issues and even collapse if left untreated.
  • Mold can grow on and inside drywall, causing it to weaken, crumble, and lose its structural integrity. Damaged sections may have to be replaced.
  • Mold growth can degrade insulation materials, reducing their effectiveness.
  • The mold that grows under carpets, on subfloors, and in other flooring materials can cause them to warp, discolor, and deteriorate.
  • Mold often causes unsightly stains and discolorations that may be difficult to remove.
  • Mold growth can cause paint to peel or bubble, damaging the appearance of walls and ceilings.
  • Mold can grow inside HVAC ducts, spreading spores throughout the home every time the system is used. This not only damages the ductwork but also exacerbates mold-related health issues. It can also damage HVAC components, such as filters, coils, and fans.
  • Mold can even grow on and degrade the insulation around electrical wiring, increasing the risk of short circuits and electrical fires.

In addition to physical damage to your home, mold growth can cause a variety of health issues, especially for infants, young children, seniors, and individuals with allergies, asthma, or weakened immune systems. Mold spores in the air can significantly reduce indoor air quality, causing health issues such as respiratory problems, allergic reactions, and asthma attacks. Some molds even release substances called mycotoxins that can cause severe respiratory or neurological issues in certain individuals.

Mold also produces a musty odor that can permeate the home, making it unpleasant and difficult to eliminate without thorough cleaning, ventilation, and remediation.


While it’s almost impossible to keep mold out of our homes, there are steps homeowners can take to prevent mold growth:

  • Keep indoor humidity levels below 60%, ideally between 30-50%. Use a dehumidifier if necessary.
  • Ensure proper ventilation. To remove moisture, use exhaust fans in bathrooms, kitchens, and laundry rooms.
  • Consider using mold-resistant drywall, paint, and other products in moisture-prone areas.
  • Mold requires moisture to grow. Repair any leaks in roofs, walls, or plumbing to prevent mold from growing. If a spill or leak occurs, wipe or mop the affected surfaces as soon as possible.

Preventing and addressing mold growth promptly is crucial to minimize damage. If mold is already present, professional remediation may be necessary to safely and effectively remove and repair any damage.
