Our windows act as barriers between the outside world and the interior of our house while still letting light and air circulate. Windows are prone to having problems like mould, mildew, and algae because of the circulating air, dust, organic debris, and moisture. The seals that keep glass panes inside their frames prevent this exchange, but they can get weaker with time, especially if you don’t maintain them properly.
This is why it’s crucial to know how to spot mould, mildew, or algae and always try to prevent them rather than waiting for them to appear.
Why Does Algae Grow on Windows?
Windows are often exposed to harsh conditions brought by weather or the activities inside our home. Excessive moisture is usually the culprit when organic health hazards appear. Bathroom and kitchen windows have a higher risk of experiencing mould or algae growth, so it’s crucial to pay extra attention to them when window cleaning.
Glass panes have a smooth surface, but pores can still exist if the glass is not ion-blasted or protected by a sealant. If moisture keeps on pooling in these pores, it can encourage organic growth. However, most problems appear when the glass panels meet the framing or within it. Sliding, double-paned, or timber windows are prone to develop mould, mildew, or algae because they tend to trap moisture and dirt.
Is Algae Harmful to Humans?
Any organic matter like algae or mould that develops around moist, damp places can harm our health. People with allergies, asthma or other respiratory problems are most sensitive to organic hazards, but healthy people can get irritations too.
Algae can be toxic, allergenic, and pathogenic, and you should always remove any that you spot. Symptoms of irritation from algae can include an itchy nose, sudden skin rashes, watery eyes and nose, coughing, and sneezing.
Algae and mould grow in similar conditions, but they are not the same. Mould is a fungus and harmful because of the spores it expels, while algae are more plant-like. Both are very damaging to your home and health.
Some species of mould, like black mould, are also toxicogenic, which means you get mould poisoning if you don’t eliminate the problem soon enough. Black mould is dark green or black in colour and typically presents as gatherings of tiny spots around problematic areas.
Cause and Effect
Homeowners should understand that algae, mould, or mildew are usually symptoms of a bigger problem. There are solutions to temporarily remove them from the area, but it’s necessary to eliminate the cause if you want to avoid them in the future. Excessive moisture, improper ventilation or insulation, and plumbing issues are some common causes of mould and algae on windows.
