What causes mould in buildings?

Old and even new buildings often get mouldy during the colder months. Whether you are living in a domestic flat or a commercial office, we’ve all had to deal with mould in buildings at some point. And despite what people may tell you, it is never just as simple as wiping it off and leaving it there.

Recently, the awareness of mould-related health concerns has grown significantly, prompting individuals to seek practical solutions for their homes, offices, and other indoor spaces. ASK Building & Repairs understands the importance of maintaining a healthy living environment, and we’re here to provide affordable services that address mould and moisture issues. In this article, we’ll explore the impact of mould, its sources, and how ASK Building & Repairs can help you prevent and eliminate these problems without breaking the bank.

Understanding Mould and Its Impact on Buildings


Mould, a type of filamentous fungi, threatens both the structural integrity of buildings and the health of occupants. ASK Building & Repairs recognises the urgency of tackling this issue, especially considering the various health effects of mould exposure, such as respiratory symptoms, asthma, and COPD.

Identifying Moisture Sources


To effectively address mould problems, it’s crucial to understand the sources of moisture in buildings. Common culprits include poor ventilation, unheated or poorly insulated rooms, excessive moisture in the air, and water damage from leaks or condensation. ASK Building & Repairs specialises in identifying and rectifying these issues to eliminate the conditions conducive to mould growth.

The Role of Moisture in Building Damage

Moisture damage is a significant concern, contributing to approximately 75% of building envelope problems. ASK Building & Repairs emphasises controlling moisture entry, accumulation, and removal to prevent issues like rainwater infiltration, porous material water travel, and condensation on building elements.

Preventing Moisture Effects of Mould in Buildings


The construction industry must adopt strategies controlling moisture entry and accumulation to combat excess moisture and dampness. ASK Building & Repairs recommends a comprehensive approach, including airtightness, ventilation, and thermal bridge-free design, to ensure long-term protection against moisture-related problems.

Ventilation Solutions to Deal with Mould in Buildings


Ventilation is a critical component of moisture control, and ASK Building & Repairs offers practical solutions. Natural ventilation, while cost-effective, requires careful consideration to prevent dampness and health issues. For a more controlled approach, mechanical ventilation systems, such as LUNOS Heat Recovery Ventilation, provide energy-efficient solutions tailored to your needs.

Airtightness and Vapour Control


ASK Building & Repairs employs advanced technologies like VARA PLUS and VARA FLUID bright vapour control layers to manage air leakage and vapour diffusion. These solutions adapt to changing conditions, offering optimum protection against moisture during both summer and winter.

Thermal Bridge-Free Design

Controlling thermal bridges is crucial in preventing condensation and mould growth. ASK Building & Repairs recommends thermal bridge-free design through materials like ALMA VERT, a recycled structural insulation panel, to enhance energy efficiency and reduce thermal bridges effectively.
