Building a new house or renovating an existing one is an exciting and challenging experience for homeowners and construction professionals alike. Unfortunately, the presence of mold in new construction can turn this experience into a nightmare. Mold can grow and spread quickly, and it can be difficult and expensive to remove. Therefore, it is essential to take steps to prevent mold in new construction and to address it promptly if it appears. In this article, we’ll discuss what causes mold in new construction, how to prevent it, and what to do if you discover it in your new building.
The Causes of Mold in New Construction
Mold is a common problem that can occur in new construction sites for various reasons. Below are the leading causes of mold formation in new buildings:
Poor ventilation
When air in a building becomes trapped, moisture builds up and increases the chances of mold growth. This situation is exacerbated when the HVAC system is not in use during construction.
High humidity
Humidity levels above 60% create the perfect environment for mold growth. During the construction process, building materials such as wood, drywall, and concrete absorb moisture, promoting mold growth if not properly ventilated.
Inadequate moisture management during construction
Water damage due to improper construction materials or leaking plumbing can cause mold growth, especially in places that are susceptible to moisture buildup.
Poor quality building materials
When cheap, inferior materials are used in a new construction project, they are more prone to moisture retention, leading to mold growth. Supporting structures like insulation and drywall are vulnerable to mold.
Delayed construction schedules
Construction delays increase the amount of time building materials are exposed to moisture, which is risky for mold blooms. Additionally, construction materials may sit in storage and exposed to moisture, creating the perfect breeding grounds for mold.
Lack of proper mold testing
After construction, it is crucial to test for mold before moving into the new construction as mold growth may occur without visible signs. Neglecting proper mold testing can result in unnecessary health risks.
Ineffectual cleaning practices
Mold can be transferred to a new construction site through inadequate cleaning practices of previous construction debris. This inadequate cleaning results in the transfer of bacteria, viruses, fungi, and mold spores to new buildings, which can create the perfect environment for mold growth.
The Effects of Mold in New Construction
While new constructions are meant to be free from any hazards, circumstances may cause mold growth. It is important to be aware of the potential dangers of mold in new construction, which include:
Structural Damage
Mold can grow and eat away materials used in the construction of a new building, such as wood, plaster, drywall, and other cellulose-based materials, leading to structural damage. When mold is not addressed promptly, this can lead to the need to replace the damaged structures.
Health risks
Exposure to mold can be dangerous since it can cause adverse reactions such as allergies, respiratory infections, and even asthma attacks. These health risks can be particularly harmful to people who have a weakened immune system, such as children, elderly individuals, and individuals with respiratory issues.
Decreased property value
When mold growth is detected, it can adversely affect the value of the property, making it less attractive to potential buyers or tenants. This can make it more challenging to sell or rent the property, causing financial loss to the owner.
Legal liabilities
Property owners and contractors can be held accountable for any health hazards caused by mold in new constructions. Negligence or failure to adhere to building codes during construction may lead to costly legal battles and health claims from tenants and other affected individuals.
Why Does Mold Grow in New Construction?
Even new construction can develop mold problems. With the current trend of making buildings more energy-efficient, buildings are being built with better insulation and better sealing which means there’s less air flow. With less air circulation, moisture will start to accumulate in certain areas, and these wet areas are perfect environments for mold growth. This is why it’s essential to get ahead of any moisture issues in your new construction project.
High Humidity from Building Materials
New construction materials such as cement, paint, and wood can contain a lot of moisture. As these materials dry and cure, they release water vapor into the air, which can lead to high levels of humidity in the building. This humidity creates a perfect environment for mold growth in new construction.
Inadequate Ventilation
New construction designs often involve creating tight seals and restricting ventilation to improve energy efficiency, which can create an environment where mold can flourish. Without proper ventilation, moisture cannot escape, and it becomes increasingly difficult to control moisture levels in the building.
