An important way to reduce condensation is to lower the level of humidity indoors. Dehumidifiers and air conditioning units are effective ways to do this. A dehumidifier is specially designed for this and works by drawing water vapor into its tank which prevents it from accumulating on other surfaces. Another way to reduce humidity levels is by keeping the home well ventilated. Opening windows and doors is a good idea but only if the humidity level outside is lower than the humidity inside.
Pipe insulation is also a way to reduce condensation buildup. However, if you need the heat from these pipes to warm the house, this might not be the best option for you as insulating them will stop heat from escaping.
House plants do much good for an indoor environment as they often contribute to better air quality, but they also increase humidity levels in the home. If you are looking to lower humidity levels to reduce condensation, you may need to reconsider the number of indoor plants you have.
What if you have tried all these methods and still notice a lot of condensation? It may be time to have the issue looked at, as what you think is condensation may be a water leak.
