Household mould can be very dangerous if not treated in the correct way.

In some circumstances, mould in the home can cause illness, particularly for those with asthma or allergies.

Mould and mildew growth can result from excess moisture in a dwelling, posing potential health risks and causing structural damage. Maintaining a healthy indoor environment requires moisture regulation and preventing mould and fungal growth. 

This post will explain all about moisture, mould & mildew.

Elements of moisture

Principal moisture ingress and entrapment pathways within a residence consist of:

  • Roof leaks, plumbing leaks, and foundation fissures that permit the ingress of water.
  • Cooking, bathing, and inhaling all contribute to interior moisture, particularly in the case of inadequate ventilation.
  • Hydrostatic pressure acting through walls and floors facilitates basement subterranean water infiltration.
  • Condensation occurs when water vapour encounters temperature differences and remains on colder surfaces, such as external walls and windows.
  • Significant weather events that cause inundation introduce substantial volumes of water into the structure.

Who is vulnerable to mould reactions? – Further useful information

Allergy reactions to mould can result from inhaling or contacting mould particles. Symptoms include rash, sneezing, conjunctivitis, and redness of the eyes. Individuals with severe mould allergies may experience more severe reactions, such as dyspnea. 

Asthmatics who are allergic to mould may experience asthma attacks if they inhale particles. The following may be particularly susceptible to the detrimental impacts of mould:

  • Infants and youngsters
  • Elderly individuals who have undergone chemotherapy
  • HIV infection
  • Cancer
  • liver disease
  • Individuals suffering from chronic pulmonary disease

Where does mould come from? 

Common household annoyance mould flourishes in moist, humid environments. It is generated by minuscule mould spores, present everywhere in the atmosphere. These spores initiate growth and construct an intricate web of filaments upon contact with surfaces that possess favourable conditions—including moisture, temperature, and a food source such as wood or drywall. 

Eventually, this interconnected network transforms into the recognisable visible mould. Regulating humidity, addressing water leakage, and maintaining adequate ventilation in your living spaces are critical to prevent mould growth.

Getting rid of moisture 

To reduce excess moisture, target its origins:

  • Repairs: Repair any breaches; address plumbing, roofing, or foundation issues without delay to prevent the propagation of water damage.
  • Vent appliances outside the home: dryers, range hoods and lavatory fans vent humidity outside the home.
  • Use exhaust fans: Use exhaust fans to remove moisture-laden air during and after cooking and bathing.
  • Control humidity: To ensure interior humidity levels remain below the recommended 50%, employ dehumidifiers.
  • Air circulation: Maintain air circulation to prevent the accumulation of stagnant moisture in closets and crevices.
  • Insulate cold surfaces: Insulation prevents condensation by warming exterior walls, windows, and pipelines.
  • Waterproof your walls: To prevent groundwater from entering, waterproof the walls and floors of the cellar.

Prevention of mildew and mould growth

Mould growth must be prevented immediately if excessive moisture does enter a residence:

  • Use appliances with fans: Use fans, dehumidifiers, and leak repairs to dry damp areas quickly; any water intrusion should be remedied within forty-eight hours.
  • Remove correctly: Mould must be removed promptly; scrub any visible mould from surfaces or walls with detergent and dry the area thoroughly.
  • Replacement: Carpets, fabrics, and furnishings harmed by floods or spills may require replacement to prevent mould growth; therefore, porous items should be discarded.
  • Maintain appropriate humidity: Keep interior humidity levels between 30 and 50% to prevent mould growth.
  • Increase ventilation: Open windows and operate fans to circulate air whenever possible.

Particular areas vulnerable to moisture problems

Specific areas within a residence are more susceptible to moisture accumulation and the subsequent growth of mould. Prioritising prevention efforts in the following critical domains can effectively avert the onset of issues:

  • Warm and humid conditions in restrooms promote the rapid growth of mould. Use exhaust fans conscientiously both during and following bathing. 
  • Damp basements create the optimal environment for mould growth. Maintain appropriate humidity levels, waterproof basement floors and walls, and repair any gaps that permit moisture intrusion. 
  • Crawl spaces, similar to basements, may experience elevated humidity levels due to the evaporation of earth moisture. 
  • Mould may develop in attics due to roof leakage, inadequate insulation resulting in condensation on rafters, or insufficient ventilation. 
  • Once more, the elevated humidity levels found in kitchens and bathrooms render them susceptible to mould development.

Final Thoughts 

It is considerably simpler to prevent mould growth by addressing moisture issues in problematic areas in advance instead of attempting to eliminate mould once it has spread. Inspect humid areas regularly, enhance ventilation, promptly repair breaches, and ensure that your residence’s relative humidity is at its ideal. 

If you follow the directions in this post, you should be able to prevent your home from developing mould. 

Ensuring optimal indoor moisture control is of utmost importance. But if mould does begin to develop, addressing it immediately can prevent more serious complications.
