The Process: How therlo Systematically Assesses Your Mould Risk
A comprehensive mould risk analysis is the first step towards a healthy home. Our process begins with a detailed survey of your property. We examine relevant building plans, previous water damage, and usage habits. Subsequently, our certified experts conduct a visual inspection and utilise state-of-the-art measuring technology to determine moisture levels in walls, floors, and ceilings. Thermal imaging cameras uncover thermal bridges, while data loggers record the indoor climate over an extended period. This precise data forms the basis for a scientifically sound assessment of your property's individual mould risk.

Common causes of an increased risk of mould
Mould does not develop randomly. An increased risk is usually due to specific structural defects or incorrect user behaviour. The most common causes include insufficient ventilation, leading to high humidity, as well as structural thermal bridges where warm, moist indoor air condenses. Other critical factors include undiscovered water damage from leaky roofs or pipes, rising damp from the ground due to inadequate basement sealing, and insufficient thermal insulation. Our analysis precisely identifies these weaknesses to initiate targeted and sustainable countermeasures.
Measurement technology in use: From thermography to long-term measurement
For a reliable mould risk analysis, at therlo we use a mix of advanced measurement technologies. The thermographic camera visualises surface temperatures, precisely identifying thermal bridges that may serve as potential condensation points for mould. We use capacitive moisture meters to non-destructively check the moisture content in building materials. To monitor the indoor climate and ventilation behaviour, we employ data loggers that record temperature and relative humidity over days or weeks. Additionally, air samplers or contact plates can be used to quantitatively determine the spore load in the indoor air and on surfaces.
The Analysis Report: Your Roadmap to a Mould-Free Home
After completing all measurements and investigations, you will receive a comprehensive and understandable analysis report from us. This document is more than just a collection of measurement values. It interprets the results, clearly identifies risk areas, and explains the underlying causes. The core of the report is concrete, prioritized recommendations for action. These range from simple adjustments to ventilation behavior, small structural measures, to recommendations for comprehensive renovations. The report serves as an objective basis for decision-making and as a detailed roadmap for the sustainable security of your property.
Prevention: How to Actively Reduce the Risk of Mould
Prevention is the most effective protection against mould. Based on the results of our risk analysis, you can take targeted preventative measures. Correct ventilation and heating behaviour plays a central role. Regular airing, several times a day for 5-10 minutes, effectively transports moisture outside. Avoid leaving windows ajar permanently, as this cools down the walls. Keep the room temperature constant and avoid placing furniture directly against outer walls. Ensure that moisture sources such as cooking or showering are ventilated away immediately. A hygrometer helps you maintain the humidity in the optimal range of 40% to 60%.

Legal Aspects for Landlords and Tenants
Mould infestations in rental properties often lead to legal disputes. A professional mould risk analysis from therlo provides an objective and reliable basis. For landlords, the report serves as proof that the building's structure is free from defects that promote mould growth. For tenants, it can demonstrate that a structural defect exists. Our analysis clarifies the question of cause – whether it's a building defect or improper user behaviour – and thus helps to avoid or resolve disputes. It provides the necessary data basis for rent reductions, compensation claims, or planning of renovation measures and protects both parties from unjustified claims.
When is a risk analysis particularly useful?
A mould risk analysis is advisable not only when there is visible infestation. It is particularly useful before purchasing a property to uncover hidden defects and future costs. Also, after an energy-efficient renovation, such as the installation of new, tightly sealed windows, the indoor climate may change and increase the risk of mould. If residents complain of unexplained health issues like allergies or respiratory problems, an analysis can provide insight into a possible mould spore exposure. Similarly, after rectified water damage, a control measurement is crucial to ensure no residual moisture remains in the building structure.
therlo vs. DIY tests: The difference lies in the precision
While DIY mould tests from the hardware store can provide an initial indication, they never replace a professional analysis. DIY tests often only measure the spore concentration at a single point in time and cannot uncover the actual cause. They do not differentiate between normal and elevated spore levels and provide no recommendations for action. Our experts at therlo, however, combine various measurement methods, interpret the results in the context of the building, and analyse the entire system of building envelope, technical equipment, and user behaviour. Only this holistic approach leads to an accurate diagnosis and effective, sustainable solutions.
How long does a mould risk analysis take?
The cost of a professional mould risk analysis is a valuable investment in your family's health and the preservation of your property's value. Consider the potential follow-up costs of undetected mould infestation: extensive renovations that can quickly reach five-figure sums, depreciation of the property, and not least the health risks. By comparison, the expense for a thorough analysis is small. You gain clarity about the condition of your building, avoid costly misinvestments in incorrect renovation measures, and protect yourself from long-term damage. The analysis quickly pays for itself through saved costs and enhanced security.
