Mould in New-Build Properties: Causes and Prevention


Unveiling the causes of mould growth in new-build properties can be a daunting task.


Poor ventilation often plays a significant role, contributing to this common issue found within newly built homes.


Moisture During Construction


The construction phase is an integral part of any new-build property project.


Particularly when water-saturated building materials are used, can create favourable conditions for mould development.


Daily Activities Leading to Mould Growth


Your daily activities could also contribute significantly towards creating an environment conducive for mould growth inside your home.


Cooking or showering without adequate ventilation leads to increased humidity levels which may trigger ventilation isn’t just about keeping you cool; it’s essential for preventing future issues like black mould infestations.


By maintaining proper air circulation during these activities, we reduce the risk associated with high moisture content that favours fungal proliferation.


In essence, understanding how various factors such as poor ventilation and excess moisture from everyday routines affect our living spaces helps us better manage potential threats posed by unwanted organisms like damp room mould.


Stay tuned as we delve into practical tips on how homeowners can prevent future encounters with these pesky fungi invading their precious indoor area.

Tips to Prevent Future Mould Problems in New-Build Homes


To protect your new-build home and ensure its longevity, it is essential to take steps to prevent mould growth.


To avoid future issues, consider these practical tips that can help you keep damp room mould at bay.


Proper Use of Extractor Fans


Cooking fumes are one source of moisture that contributes significantly to indoor humidity levels.


Extractor fans, when used correctly during cooking, can efficiently reduce this problem. They work by redirecting excess steam and heat outside, preventing an environment conducive for mould growth.


Importance of Ventilation When Showering


Showers produce high amounts of water vapour which could lead to black mould if not managed properly. Therefore it’s essential to ensure proper ventilation while showering and afterwards too. Ventilating systems or even opening windows after showers will allow the accumulated moisture from hot showers to escape instead of creating moisture inside, leading towards musty odour caused by growing fungi.


Drying Clothes Correctly


Wet clothes also contribute substantially towards increasing indoor humidity levels; hence they should be dried appropriately.


Drying them outdoors whenever possible is advisable as sunlight acts as a natural disinfectant against potential fungal spores on clothing items. If outdoor drying isn’t feasible due to weather conditions or lack of space, then opt for well-ventilated areas indoors with open windows which will prevent the accumulation of excessive moist air, thus helping homeowners avoid creating suitable environments for mould propagation.


Remember, prevention is always better than cure, so adopting the right practices in the early stages will save a lot of trouble down the line, ensuring a healthy living atmosphere within a newly built house free from any kind of harmful moulds.
